System Center Licences help
Hi,
I`m planning to buy System Center and have some doubts about witch licences i need.
I have a 3 node vmware cluster with 96 total physycal cores.
I’m planning to use configuration manager to manage deployment, updates and app installation on near 400 client pc.
As i understand if i buy datacenter edition i can manage all windows servers on the cluster and have to buy 400 operations manager client licences for client pc’s and with standard i have to buy client licences for servers to.
Is that ok?
Thanks

Adding TEAMS meetings to personal calendar -Free version
Hi!
I am trying to work out how to add my Teams meetings to my calendar whilst using the free version. There seems to be no calendar link at all. I have seen some extensions but they only work for the organisation/work package. I would prefer to link my Google calendar though have an Outlook calendar I could link if it’s easier.
Can anyone help? Thanks 😁

Copilot Does Not Summarise Slides in Powerpoint
I have a 40 slide presentation. Some of the slides are particularly wordy, so what I was planning to do was to ask Copilot to summarise a series of slides and add that as a companion document to the presentation.
When I ask it to summarise a single slide by asking it to “Summarise slide 5” it grabs a title from a previous headline slide and creates a summary based seemingly on the whole presentation. If I ask it to summarise multiple slides with “Please summarise slides 5, 7, 10….” It creates a headline for each slide but summarises the wrong slides throughout and places the wrong titles on each slide in the response.
Anyone else tried summarising specific slides in a presentation?

The New Entra ID Photo Update Settings Policy for User Profile Photos
A new Entra ID photo update settings policy aims to cure the mish-mash of existing settings controlling how user profile photos are updated in Microsoft 365. The new policy is based on a Microsoft Graph resource. Work is needed to update clients to respect the policy settings and take over from current controls, like the OWA mailbox policy.

How do I get HP Bloatware script to run during enrollment?
Hi all
I am wanting to put a script within Intune so during the deployment phase of autopilot it would remove the HP Bloatware however if I attach this script
https://gist.github.com/mark05e/a79221b4245962a477a49eb281d97388 into the deployment policy it would fail everytime.
I can only remove it by going to the start menu , run powershell as admin and then run the script manually from there.
What do I need to add so the script can run automatically?
It wouldn’t matter if it can’t be run during the enrollment stage but I do want to somehow automatic this .
Thanks

Windows 365 GPOs instead of Intune Policies
Hi,
can i set the Windows 365 specific settings (except the provisioning policy) like RDS-Policy via Group Policies, or due i always have to use Intune Profiles?
If GPO are possible, where do i find the requires admx-files

Moving from Amazon Quantum Ledger Database (QLDB) to ledger in Azure SQL
Overview
Amazon Web Services (AWS) has announced the discontinuation of its Amazon Quantum Ledger Database (QLDB). Their documentation has been updated to indicate that support for QLDB will end on July 31, 2025. AWS’s decision has prompted many customers to explore alternative solutions for their ledger database needs.
Introducing ledger in Azure SQL
AWS propose Aurora PostgreSQL for audit use cases as an alternative to QLDB for common ledger database use cases. While Aurora offers detailed audit logging and permanent log retention, it does not include cryptographic verifiability.
Microsoft offers an excellent replacement through its ledger feature in Azure SQL. It provides similar functionalities, ensuring data integrity through cryptographic verification, and leverages the full capabilities of Azure SQL. Ledger is a feature that offers the power of Blockchain in Azure SQL Database, Azure SQL Managed Instance and SQL Server. Ledger allows establishing trust across different business entities while maintaining the simplicity and performance of a relational database. The data is centrally managed, and you can cryptographically attest to other parties, such as auditors or business partners, that your data can be trusted and hasn’t been tampered with.
More information about ledger in Azure SQL and SQL Server can be found in the ledger documentation.
Key features of ledger
Captures and cryptographically links data changes to make the data tamper-evident and verifiable.
Uses the same SQL environment you already know.
Is easy to deploy and maintain.
It comes with NO extra cost.
Migration support
Amazon QLDB uses a document-oriented data model. The complexity lies in normalizing data during migration, converting the document model into a relational model, and handling any changes to the document model. Microsoft can assist organizations in migrating from Amazon QLDB to Azure SQL Database. For more detailed information and to initiate the migration process, organizations are encouraged to contact Microsoft support or their Microsoft Account Manager.
Conclusion
Even though QLDB is being phased out, Microsoft offers an excellent alternative for users to host their data with cryptographic immutability. This ensures they can uphold rigorous data integrity standards. Ledger in Azure SQL serves as a strong alternative, with effortless integration into the Azure SQL environment.

Exclamation mark instead of unread messages – bad user experience
Hi,
Since the new teams i get sometimes the exclamation mark and i have an “account problem” with one of my customers. Normally my signin is expired there and i need to resign in.
But i do not need them at the moment. The exclamation mark kills the “unread messages” number on my taskbar – which is needed. Anyone else experiencing this? Signing in to the customer tenant(s) is no real solution – as this disrupts the work flow.

How to disable two/three-finger zoom (pinch) in app on touchscreen?
I have an app developed with AppDesigner that you can see below on the left. It is being run on a touchscreen. Using two or three fingers (also called a "pinch") on the touchscreen, it is possible to zoom in on the app window contents. The picture on the right shows what is happening (and apologies for the glare). This was reproduced across two OSs and two different touchscreens, which suggests it is something inherent to MATLAB. This only appears to be possible with a touchscreen, since I was unable to zoom like this using combinations of mouse and/or keyboard.

Assistance Needed: Simulating Power-Exponent-Phase Vortex Beam (PEPVB) Propagation in Oceanic Turbulence
I am attempting to simulate the propagation characteristics of the Power-Exponent-Phase Vortex Beam (PEPVB) in oceanic turbulence based on the theoretical model provided in the paper Propagation properties of rotationally-symmetric power-exponent-phase vortex beam through oceanic turbulence. The model uses the extended Huygens-Fresnel diffraction integral and oceanic turbulence theory, and I’m trying to implement this in MATLAB.
I have followed the mathematical formulas provided in section 2 of the paper, particularly equations (1) to (8), which define the electric field and cross-spectral density for the PEPVB passing through turbulence. However, despite various attempts, I haven’t been able to get the simulation to work as expected.
The first image shows the results I generated using my own code, while the second image shows the results provided by the authors of the PEPVB study. The differences between these results are confusing me, especially regarding the implementation of the electric field formulas and how to handle the oceanic turbulence parameters, such as the rate of dissipation of turbulence kinetic energy (ε), the temperature-salinity contribution ratio (ω), and the dissipation rate of the mean-squared temperature (χT).
Could anyone with experience in PEPVB or similar simulations in MATLAB help me check my code or provide working examples? Any help would be greatly appreciated!

Beta channel selection disabled and unselectable after reboot
Hello everyone,
Yesterday I downloaded the iso of the latest 24h2 release preview and installed it, then chose the beta channel as the insider subscription type, but when I restarted it didn’t keep the selection because I saw myself in release preview without the possibility of choosing the beta channel, which in fact is grayed out and not selectable, while dev and canary can be chosen.
Currently, I am in release preview with build 26100.1742 ge_release.
I installed all the updates and restarted again, but nothing has changed.
Can you tell me why and where I went wrong?
Thanks everyone.

Filter SAP Data at source with Synapse/ADF CDC
Hi everyone,
I’m currently working on a project in Azure Synapse where I’m using the SAP CDC Connector to connect to an S4Hana system. My goal is to filter data on the source side before storing it in my ADLS Gen2, as there are certain data restrictions that I need to adhere to.
I need to fetch multiple objects from SAP, and I typically use a parameterized approach for this. I have a JSON file that contains parameters and queries for each object I want to retrieve from the source. For instance, I define SQL queries in the JSON file to perform the filtering. This method works well with SQL Connectors.
However, with the SAP CDC Connector, I haven’t been able to find any functionality that allows me to apply such filtering directly at the source.
Here’s what I’m doing so far:
I’m currently using a dataflow in a for each loop. In the dataflow however, I cannot pass SQL queries and Im stuck with the expression builder. I cannot figure out how to dynamically pass query like filtering. So Im just getting the unfiltered objects, which is not an option. I have so many objects, that I cant maintain a non parameterized version.
I tried using a copy data activity as well, however when selecting it, I do not get the option to choose the SAP CDC Integration Dataset.
Has anyone successfully managed to filter tables at the source when using the SAP CDC linked service? Any insights or suggestions on how to achieve this would be greatly appreciated.
Thanks in advance for your help!
Hi everyone, I’m currently working on a project in Azure Synapse where I’m using the SAP CDC Connector to connect to an S4Hana system. My goal is to filter data on the source side before storing it in my ADLS Gen2, as there are certain data restrictions that I need to adhere to.I need to fetch multiple objects from SAP, and I typically use a parameterized approach for this. I have a JSON file that contains parameters and queries for each object I want to retrieve from the source. For instance, I define SQL queries in the JSON file to perform the filtering. This method works well with SQL Connectors.However, with the SAP CDC Connector, I haven’t been able to find any functionality that allows me to apply such filtering directly at the source.

Grades app – filter by TAG
On the grades app, I can filter by date range, and by grading category. I have the need to filter by TAG
(I co-teach a class with a colleague, we use categories for TYPE of assignment, and tags to mark WHICH of us is associated with the assignment…. and I’d like to filter this).
Hopefully, it should be an uncontentious tweak to make!

Entra Connect Sync duplicated UPN
Hi
I had Entra Connect running for a long time without issues. Out of the blue Connect Sync started to report Duplicate Attribute on 3 users User Principal Name.
The 3 users, Connect Sync believe has a conflicting value in Entra, do exist in Entra, but with a smtp address which matches the UPN, and is not the the users UPN.
If i run the following command on my on-prem AD the UPN does not exist in any form of domain name:
Get-ADUser -Filter {UserPrincipalName -eq “email address removed for privacy reasons”}
Get-ADUser -Filter {UserPrincipalName -eq “e-mail@domain.local”}
Get-ADUser -Filter {UserPrincipalName -eq “email address removed for privacy reasons”}
All my users UPN are different from the configured on-prem ProxyAddresses so the above error mesage makes no sense. And futher more the 3 users which sync sees as a conflict do not even has a ProxyAddresses configured.
Any ideas how to futher debug this?
