Use WinGet 1.8 to download Microsoft Store apps
Windows Package Manager (WinGet) 1.8 now allows IT professionals to download Microsoft Store apps.
What is WinGet?
WinGet is a command-line tool that enables you to install and manage applications on Windows 10 and Windows 11 devices. WinGet supports a variety of sources, and it allows you to automate the installation and update process of applications, as well as to search and discover new apps.
What is WinGet Download?
WinGet Download provides the ability to download Microsoft Store apps for offline distribution to other devices in your network. This feature replaces the Enterprise Offline feature from the Microsoft Store for Business.
How can I use WinGet 1.8 to download Microsoft Store apps?
To use WinGet to download Microsoft Store apps, you need to have the latest version of WinGet installed on your device. You can check your WinGet version by running the command winget –version in a PowerShell or Command Prompt window. If you need to update WinGet, download the latest installer, run the command winget upgrade winget, or update App Installer from the Microsoft Store.
To download a Microsoft Store app, you can use the winget download command. For example, you can run the command winget download Calculator -s msstore to download the Calculator app from the Microsoft Store. This will create a folder in your Downloads directory, where you can find the downloaded app package. You can then copy the app package to another device and install it using the Add-AppxPackage PowerShell cmdlet. Run the command Add-AppxPackage -Path C:Usersusernamedownloads9WZDNCRFHVN5Calculator.appx to install the Calculator app on another device.
To learn more about WinGet 1.8 and its features, read the Windows Package Manager documentation and winget tool documentation.

Usability is lacking
My school recently switched from Google to Microsoft and there are a lot of things I like about Outlook but there are also a lot of features or lack thereof that I am finding extremely frustrating. One thing that has been extremely frustrating is that when I look up how to do something I will find the instructions from Microsoft but the instructions are not effective. For example, I looked up how to find deleted events in Calendar and it says to click on the “Folders” tab at the top but there is no folders tab. Similarly, when I looked up how to view flagged items it gave the option of using the “Folders” tab again in Outlook email but there isn’t a folders tab. I was eventually able to figure out how to view the flagged items. I just wanted to share some of my frustrations in the hope that you will be able to make improvements on the usability or at least the instructions provided online regarding how to use features or access different things on you software.
Also, I still can’t figure out how to access deleted events in calendar and would like some assistance. And please, don’t tell me to click on the Folders tab.

Dax measure doesn’t return correct total value in all rows
Hi,
Created a measure as below:
Its giving me the correct values at filter context and total as well as shown below:
My expected outcome of this measure should be:
total 0.17 should be in all rows of DBName-point id(filter context) and not their individual values(for ex: INSE-1000 should have 0.17 instead of 0.12)
In order to achieve that,i created a measure as below:
But then it gives 0.155 in all rows rather than 0.17
To elaborate with another example:
Please find the below sample data link:
Below screenshot shows, dax measure ‘
I wrote a measure ‘Invoice Unit Rate test 3‘ as below to display the total of ‘Invoice Unit Rate test 2‘ in all rows:
But my result is as below:

Properties are not applicable to connector of type ‘OnPremises’ with the current combination.
It has come to my attention that there are new limitations on Inbound on-premise connectors. Specifically, the following options are no longer available:
• RequireTls
• RestrictDomainsToCertificate
• RestrictDomainsToIpAddresses
This change appears to be quite recent, as I’m unable to find any discussions about it online. The impact is significant – I can neither create new Inbound on-premises scoped connectors nor modify existing ones within our tenant.
Upon investigation, I discovered that Microsoft updated their documentation just four days ago. The GitHub commit (https://github.com/MicrosoftDocs/office-docs-powershell/commit/8ca7602b857e07f8d760922af0c3ca98a107c22d) indicates that these flags are now exclusively for Partner type connectors.
This change seems counterintuitive, as it prevents the creation of new connectors using the Exchange GUI or PowerShell with the recommended “Authenticating sent email” settings. These settings typically involve verifying that the subject name on the server’s authentication certificate matches the specified domain.
I’ve attached screenshots demonstrating the inability to update existing connectors with these flags or add new ones with these settings.
Has anyone else encountered this issue or have any insights into these recent changes?

Azure Monitor Logs Next Evolution: Multi-tier logging
Today we’re announcing the public preview of Auxiliary Logs, a new inexpensive Azure Monitor plan for verbose logs used in compliance and security scenarios. Together with the recent public preview of Summary Rules and improved capabilities of Basic Logs, Azure Monitor Logs is evolving into a new multi-tier logging vision.
Most organizations have many different needs for logging. This is because not all logs are the same – some are very frequently accessed, some are needed for investigation when issues arise, and some are kept mostly for audit and compliance purposes. When we talk to customers, we often hear that they use multiple logging services or products side-by-side to serve their needs, and this is slowing them down. They need to deploy, maintain and learn several different technologies just to observe their services. Customers are also telling us that they need to log much more data than before, which is ballooning their logging cost.
Azure Monitor is focused on addressing these problems with a single solution that includes multiple logging plans that cover a broad variety of scenarios. With Azure Monitor Logs, customers have a one-stop shop for observability.
These log plans are:
Auxiliary Logs – Our new, inexpensive log plan that enables ingestion and management of verbose logs needed for auditing and compliance scenarios. These may be queried with KQL on an infrequent basis and used to generate summaries.
Basic Logs – Improved to support even richer troubleshooting and incident response with fast queries while saving costs. Now available with a longer retention period and the addition of KQL operators to aggregate and lookup.
Analytics Logs – This plan is designed for frequent, concurrent access and supports interactive usage by multiple users. This plan drives the features in Azure Monitor Insights and powers Microsoft Sentinel. It is designed to manage critical and frequently accessed logs optimized for dashboards, alerts, and business advanced queries.
For detailed capabilities comparison between the plans, see our documentation. For the pricing of these plans, see here.
All these logs can be retained for up to 12 years, while being accessible using Search Jobs, that can scan Petabytes of data to find specific records.
Since all these logs are in Azure Monitor, it means that they have the same KQL query language, API, query and admin experiences. Furthermore, we’re not only integrating these logs under one roof, but also are providing additional capabilities to ensure that logs function cohesively:
Summary Rules – Continuous aggregation of raw data into compact summaries that are easier to analyze and cheaper to retain
Ingestion transformations – Enable filtering, enriching, and splitting data between log plans during ingestion
Search Job – An orchestrated long-running query that can scan Petabytes of historical data to specific records into Analytics tables for further analysis
With this, it is easy to switch or mix-and-match between the different log plans. Customers can start with a table that is configured with the Analytics plan, then can check if Basic Logs works for them through a simple configuration change. If they find that they need more capabilities, they can revert to Analytics.
Here are two examples how these plans work together to create an improved solution:
Firewall logs can be huge, 100s of TB per day of highly verbose data. Firewalls are optimized to omit all communications details. While most consumers don’t need the raw data for day-to-day use, organizations do need to keep it for auditing. In Azure Monitor, customers can now send all firewall logs to Auxiliary Logs and retain them per compliance requirements. On this data, customers can run a summary rule that creates hourly aggregations. Investigators can use these aggregations for their day-to-day work and if they need to drill down, they can easily query the relevant records from Auxiliary Logs.
Some logs contain highly important information mixed with less important data. Customers can send these logs using our pipeline Data Collection Rules and split the data between Analytics and Basic Logs. The highly important records will have all analytics capabilities, while the less important information will be available for troubleshooting at a lower.
We are working closely with our customers to collect feedback and will continue to add more functionality to the service. We are always interested in hearing your thoughts and understanding how you apply Azure Monitor Logs to your environment. You can contact us using lafeedback@microsoft.com or via our feedback community forum.

The Mathieu Equation—Stability for 2DOF whirlflutter system

Is my approach for determining the Stiffnesses and angles correct, and how can I change the process using the Floquet technique and the Mathieu equation? Because ultimately, the boundries are not shown correctly according to the reference.

Just wondering–have they fixed the problem with contact lists?
I am using MS365 and Windows 11 on a new computer. I had to manually enter all my email contacts because the last computer’s hard drive died and took them with it. So I got done with one of my contact lists and attempted to send an email using the contact list–150 emails. Finished the message, put the contact list into BCC and nothing. Checked the contact list title–says there’s no addresses in it. Redid the contact list–same thing. Finally downloaded my email addresses to the old Outlook and sent the message that way–needed to get it out today. Did anyone get this figured out yet?

Easily deploy .NET apps to Azure Container Apps with default configuration for data protection
The Azure Container Apps and .NET team have made it easier than ever to deploy your .NET application by supporting automatic configuration for data protection. This support is currently available as an opt-in feature in the Container Apps API version 2024-02-02-preview.
This blog post will discuss the feature and what it enables, how to determine if your application is correctly configured, and how to enable configuration for data protection across a variety of .NET versions.
What is data protection?
Many ASP.NET Core apps rely on a feature called data protection, which is a cryptographic API to protect data using methods like key management and rotation. By default, it requires additional configuration in both Azure and in application code to function correctly when hosted in Container Apps.
If data protection isn’t configured, the application will appear to function correctly but will experience bugs when the application scales out to multiple replicas.
For detailed information about the data protection feature, read here.
Configuring data protection for your .NET Application
The process of configuring the data protection feature varies depending on the version of .NET you are using.
.NET Aspire
Aspire applications deployed using the Azure Developer CLI (azd) will have data protection configured by default.
.NET 8 and up
If you are using ASP.NET Core v9.0.0-preview.2.24128.4 and later and ASP.NET Core v8.0.4 and newer, you can configure data protection using ARM and Bicep.
This can be done with turning on the new `autoConfigureDataProtection` property, which will allow ASP.NET Core data protection keys to be automatically managed by the platform.
.NET 7 and under
If you are using ASP.NET Core with a lower version than previously described, you will have to configure data protection manually. We recommend upgrading to one of the supported .NET versions or doing so using ARM.
Next Steps
Congratulations, you now ensured that your .NET application has data protection correctly configured and will scale to multiple replicas without issue!

Windows Admin Center (v2) Public Preview build has been updated!
It’s been seven months since we released the last Public Preview for our “Modernized Gateway” (known as v2) — today, we’re updating the Public Preview build with new functionality and bug fixes. As we get closer to officially releasing this version to general availability (GA), we want to hear from you first so that we proactively address any feedback you may have!
Please note that this is still a Public Preview version of Windows Admin Center, so it is not recommended to install this build in your production environment. This preview version will no longer be able to be installed side-by-side with the last GA release (version 2311, or any of the previous releases). Once you install this build and migrate your user data and environment configurations, you will not be able to go back.
We’ve been working behind the scenes to ensure that Windows Admin Center is up-to-date, secure, and reliable. We suggest experienced users of Windows Admin Center and Windows Admin Center developers give this new build a try. Read on to learn about the new features and updates!
What’s new in this v2 build
Upgrade to .NET Core
The Windows Admin Center frontend user-interface (UI) is built on Angular, which is in turn built on our shell. The shell hosts all the core services and most of our UI components, our solutions like server and cluster manager, and, on top of that, every extension that you use for server management.
Our front end interacts with our backend, which is also known as our gateway. The gateway hosts our authorization structure, our PS services, our gateway plug-ins, and plays a critical role in every single experience that you use in Windows Admin Center.
In this release, we have upgraded our backend again, from the .NET Core 6 to .NET Core 8, bringing enhanced security and improved cryptography to our product. This also includes support for HTTP 2, reducing latency and enhancing the responsiveness of Windows Admin Center. Combined with improved performance, providing faster load times, you’ll be able to get your tasks done more quickly and efficiently.
Virtual machine tool update
We have heard your feedback and have improved the virtual machine (VM) tool experience! Our primary goal is to provide you with the list of VMs as soon as possible so you are empowered to efficiently carry out your administrative tasks.
Today, we invite you all to enable this feature, use the tool, and share your feedback.
Highlights:
The VM Power operations (e.g. start, pause etc.) now only update the VM selected without reloading the entire table, saving customers valuable time
To optimize responsiveness (e.g., clicking, hovering and scrolling), we have removed the runtime pipeline.
To prioritize loading the VM list first, certain operations are deferred until after the initial load (e.g., cluster node check)
To optimize performance, we have reduced the columns in the default view. Note that this can be toggled off using the “Detailed Mode” toggle to switch back to the previous experience
A new streamlined Azure Site Recovery integration experience for users
How to enable the feature
Navigate to your Windows Admin Center settings by selecting the gear in the top right corner of the header.
Navigate to the “Advanced” tab.
Add the following experiment key: msft.sme.hyperv.hyperVPreviewMode
Updated installer
While modernizing our gateway, we also made the installer more flexible by providing increased customization options including network access settings, selecting trusted hosts, providing a fully qualified domain name (FQDN) for your gateway machine, and more. For more details about the installer, read on to the Installing the v2 build section.
Data migration
To ensure that your user and environment data is transferred over, we have implemented a data migration flow so that you will seamlessly transition to the new v2 build. All of your data will be copied over, except for 4 items that will require user intervention. For more details about the installer, read on to the Migrating your data section.
Settings update
As part of our gateway modernization effort, you may notice that your Windows Admin Center settings look a little bit different.
As we discussed in the 2211 Windows Admin Center release, we have deprecated the in-app update experience and have consequently removed the settings blade for Updates. Additionally, the Access and Shared Connections blades are now available on local gateway installations (also known as “desktop mode” in legacy gateway builds).
Multi-process, micro-service based
The v2 build also leverages microservice architecture. Prior to this upgrade, Windows Admin Center performed all tasks in a single process. With our new model, we start one process for Windows Admin Center on application startup that serves as a process manager. As you use Windows Admin Center, additional sub-processes are spun up to perform specific tasks.
Additionally, gateway plug-ins that are compatible with the v2 build will also run their own collection of sub-processes under the Windows Admin Center service manager to perform their functions.
Changing from a monolithic service to a microservice model helps our v2 build be more flexible, scalable, and resilient.
Kestrel HTTP web server
Previously, Windows Admin Center utilized Katana components, including a web server, on the backend. With the v2 build, we’ve shifted to an ASP.NET Core Kestrel web server.
Kestrel is the recommended web server for ASP.NET Core applications. Kestrel is:
High performing: Kestrel is optimized to handle a large number of concurrent connections efficiently.
Lightweight: Optimized for running in resource-constrained environments, such as containers and edge devices.
Security hardened: Kestrel supports HTTPS and is hardened against web server vulnerabilities.
Additionally, Kestrel supports the HTTP/2 web protocol, where previously we had only supported HTTP1.1 with the Katana components. The upgrade from HTTP1.1 to HTTP/2 brings reduced latency to our application as well as increased responsiveness through enhanced features like multiplexing and server push.
Switching to a Kestrel web server will also allow for Windows Admin Center to potentially enable cross-platform support in the future.
How does the v2 build impact my extension?
Gateway plug-in extensions will be the most impacted by the changes to our v2 build. Windows Admin Center gateway plug-ins enable API communication from the UI of your tool or solution to a target node. Windows Admin Center hosts a gateway service that relays commands and scripts from gateway plug-ins to be executed on target nodes. The gateway service can be extended to include custom gateway plug-ins that support protocols other than the default ones (PowerShell and WMI).
Because gateway plug-ins communicate with Windows Admin Center’s backend to enable API communication, gateway plug-in code may include components written with the .NET framework version 4.6.2, which will not function with .NET Core. This code needs to be updated to use the .NET Core framework.
Additionally, we’ve modified the way plug-ins work with our v2 build. Instead of developing a C# class which implements the IPlugIn interface from the Microsoft.ManagementExperience.FeatureInterfaces namespace to extend the gateway plug-in, extensions will now be written in the form of ASP.NET MVC controllers. These controllers have increased flexibility compared to the simple C# class and extensive documentation.
Learn more about gateway plug-in development in Windows Admin Center here.
What about my tool and/or solution extension?
Solution and tool extensions do not communicate with Windows Admin Center’s backend in-depth and should be minimally impacted by the v2 build. We strongly recommend testing your extension to ensure it continues to run smoothly on the new backend.
Installing the v2 build
With our v2 build, we’ve made changes to our installer to offer more flexibility to the user.
When running the installer, you will be presented with three different installation modes: express localhost setup, express remote setup, and custom setup.
Express setup options
Two of the three installation modes for the v2 build are express modes—express localhost setup and express remote setup.
Both express setup options do not allow for the configuration of the following features:
Login authentication mode
Host access network names
Internal and external network ports
Certificate type and thumbprint
Endpoint FQDN
Trusted hosts mode
WinRM over HTTPS
If you would like to configure any of these features, please use the custom setup option instead.
If you select the express localhost setup option, WAC will be accessible through port 6600 and will use internal ports 6601-6610.
If you select the express remote setup option, WAC will be accessible through port 443 and will use internal ports 6601-6610.
Custom setup
Selecting custom setup allows you to configure all Windows Admin Center setup options:
Network access – This page allows you to select how you will be using Windows Admin Center. You may choose to restrict WAC access to other users by selecting localhost access only or allow remote access through machine name of FQDN.
Port numbers – This page allows you to select the ports that will be reserved for Windows Admin Center. WAC uses one external port for its primary processes. Other processes use internal ports. There are two internal processes by default, but extensions may define their own services that will require port access. By default, the internal range is 10 ports.
Select TLS certificate – This page allows you to select Self-Signed certificates or an official TLS certificate that Windows Admin Center should use. Self-Signed certificates include Self-signed CA root certificates and TLS certificates that work with the latest Edge/Chrome browser.
Fully qualified domain name – This page allows you to provide a fully qualified domain name for network access. This name must match the name on the TLS certificate.
Trusted hosts – This page allows you to select which type of remote hosts you’d like to manage. You may choose to manage only trusted domain computers or allow access to non-domain joined machines.
WinRM over HTTPS – This page allows you to select whether to use HTTPS for WinRM communication. WinRM communicates over HTTP by default.
Troubleshooting installation
If your installation failed, or you’re having trouble opening WAC after install, you may need to uninstall and reinstall. This can also happen if you have an older version of a v2 build installed, and you are trying to update to a newer version. To uninstall, follow the instructions in the Uninstalling and cleanup section of this document.
Migrating your data
Once you have installed the v2 build, much of your transferable data is automatically copied over to the new build, reducing the time it takes for you to get started. However, there are four items that will require your input on:
Proxy credentials
WebSocket Origin configuration
Azure registration
Extensions
You will only have to do this once. Once your data is fully migrated, future releases of Windows Admin Center will have the seamless update experience you know and love.
Proxy credentials
Windows Admin Center will not be able to able access Azure services and the public extension feed without proper proxy credentials. If you have a proxy set up, then you will need to enter the proxy address, as well as the username and password to give Windows Admin Center access.
WebSocket Origin configuration
If you had previously configured WebSocket Origins, you can review and edit them here. To get you started, we have imported the WebSocket Origins list from your previous Windows Admin Center setup.
Azure registration
Windows Admin Center now requires additional redirect URLs to be configured with the Azure App Registration instance. This can only be done through the Azure Portal. Selecting the “Configure” button will programmatically update the Azure App Registration on your behalf. After it is registered, you may need to re-enable Azure login to Windows Admin Center.
You will need the elevated permissions on this Azure subscription to perform this re-registration.
Extensions
The extension feed for v2 builds is not currently fully configured. You may notice missing extensions from this Windows Admin Center instance, including extensions not installed by default on install and ones you may have installed from your own feed or from external partners. As of right now, this page is read-only. We’re working with our internal and external partners to ensure that all extensions are compatible with v2—these extensions will be available soon.
Review + complete
You will not be allowed to use Windows Admin Center unless you complete these steps.
Uninstalling the v2 build
To uninstall the Windows Admin Center (v2), perform one of the following actions:
In the Apps & Features page of your gateway machine settings, select Windows Admin Center (v2) Preview from the program list and then select uninstall.
Navigate to the folder where the Windows Admin Center (v2)is installed (default directory is C:ProgramDataMicrosoftWindowsStart MenuProgramsWindows Admin Center (v2)) and select “Uninstall Windows Admin Center (v2)”
Run C:Program FilesWindowsAdminCenterunins000.exe
Running the installer again will not result in an uninstall option at this time. To ensure your installation was removed successfully, check if a WindowsAdminCenter folder exists in C:ProgramData or C:Program Files. If it does not exist in either location, your application has been successfully uninstalled.
During the uninstallation process, everything put on the machine during installation will be removed, except for the Windows Admin Center (v2) .exe installer file. If you have another build of Windows Admin Center also installed at the time of your v2 build uninstallation, no files or properties of the other build will be touched during the uninstallation process. There are no interdependencies between the two installations.
FAQs
Q: Can you install a build of Windows Admin Center (v2) when you already have an existing build of Windows Admin Center installed?
A: Yes, you can install a v2 build of Windows Admin Center side-by-side with a legacy gateway build as long as you do not choose the same ports for both installations.
Q: Can I change the ports my Windows Admin Center installation is using after install?
A: Yes, In the Program Files for Windows Admin Center, we’ve included a PowerShell module called Microsoft.WindowsAdminCenter.Configuration.psm1. This module allows you to modify your WAC configuration after installation and can be found in the PowerShellModules folder of your installation (C:Program FilesWindowsAdminCenterPowerShellModules by default).
To change the ports WAC is using, run the following command:
Set-WACHttpsPort -Wacport <port> -ServicePortRangeStart <port> -ServicePortRangeEnd <port>
Q: Changing the ports is great, but can I change other configuration settings after install?
A: Yes! You may use the PowerShell module Microsoft.WindowsAdminCenter.Configuration.psm1 to change your configuration settings. It can be found in the PowerShellModules folder of your installation.
Q: Why aren’t all these changes just in the 2311 release?
A: To ensure the best quality experience, we require customer and developer feedback before these changes are generally available.
Q: Are all the features in the 2311 release available in this build?
A: Yes! Read more about the Windows Admin Center 2311 release.
Known issues
The account for the PowerShell session in the PowerShell tool always defaults to the user signed into the Windows Admin Center gateway, even if different management credentials were specified when remoting to a connection.
The extension feed for the v2 build has not been configured. Extensions not included in the Windows Admin Center installer (including external partner extensions) will not be available unless you add an extension feed. Even with an added feed, the following extensions do not currently function with the v2 build:
Dell OpenManage
Lenovo XClarity Integrator
HPE OneView
HPE Server extension and HPE Azure Stack HCI extension
HPE Storage manager
Fujitsu ServerView RAID
Fujitsu Software Infrastructure Manager (ISM)
Fujitsu ServerView Health
Pure Storage FlashArray
Looking forward
Please be on the lookout later this year for our next GA release. It will include even more features for Hyper-V, several Windows Server 2025 exclusive features, and will be the most performant build of Windows Admin Center to date!

how do i get the sigmas out of the livescript display?
Hi Everyone,
I am currently working with a very long equation. And when I output it in the livescript, MATLAB finds several sigmas (see screenshot). I would like to have this equation with the sigmas in order to process it in another function.
So far I have tried [r,sigma] = subexpr(expr). I cancelled this command after more than 1 hour of calculation. In addition, subexpr, if I have understood it correctly, only looks for one sigma.
I hope someone here can help me.

uiwait(msgbox(“My message”) dialog comes up behind the app. User never sees it.
