Keep getting mysterious CRL folder under C:
It appears that the issue might be related to expired certificates. Despite conducting fresh installations of Windows, the problem of a folder containing around 10-15 .crl files persists. Even after deletion, the folder reappears consistently. Concerns about a potential hacking incident or a browser-related complication arise. Unfortunately, seeking assistance from Google has not yielded any helpful information on this matter.

Copilot+ PC laptop
This is my updated review of the Samsung Galaxy Book4 Edge Copilot+ PC. I recently purchased it at a discounted price.
The device is powered by a robust Snapdragon X Elite processor, running at 3.4GHz with 12 cores (X1E-80-100). Initially, it came with Windows Home edition, but I later upgraded it to the Pro build 26100.863.
I found the Samsung Copilot+ PC ARM laptop to be quite demanding in terms of how it functions. During setup, it automatically synced several unwanted folders from my LG Laptop, likely from One Drive, onto the desktop. I had to manually unsync them to tidy up the interface.
After using the device for three weeks, it suddenly stopped working, leaving me with a dreaded “Startup repair couldn’t repair your PC” error message. Despite creating two system image backups, neither of them could be detected by the recovery tool, displaying a frustrating “Windows cannot find a system image on this computer” prompt. Even attempting a factory reset failed multiple times, halting at 35.0% of Applying Image stage with an error stating “failed to install recovery file.”
In my desperate attempt to salvage the situation, I tried installing a different ARM OS, only to encounter issues with the keyboard and mouse freezing during crucial setup stages. Eventually, I decided to seek help at the Samsung store in Glendale, CA. An experienced technician wiped the system and installed Windows 11 along with some additional apps. After a 2+ hour wait, I received the device back with only the essential recovery and system partitions visible, but they appeared to be empty.
I would appreciate hearing about others’ experiences with this device.

How can I remove a line off UIAxes on App designer in RealTime with SpeedGoat
Hi,
Im creating an app using App designer and Simulink in Realtime with a speedgoat. I have a drop down menu that has a selection of position or velocity. Depending on what is selected I want to plot it on a UIaxes. However, for instance, when I go from velocity to poisition or vice versa, The graph keeps both lines on the UIAxes. I only need to show one line that corresponds to the value of the dropdown list. Im using connectline() command to plot. I tried using clearScalarAndLineData() command to clear the axes but it is not working. My issue is that I cannot get rid of a line once I use the connectline() command. I also tried using cla() but once I use it, it will not replot during the simulation.
My desire is to have when the dropdown list equals to position, the UIaxes will plot only the position signal and when the dropdown list equals velocity, it will only plot the velocity signal during simulation.
Here is my code so far
function PlotSelectValueChanged(app, event)
value = app.PlotSelect.Value;
if value == "Position"
app.Instrument = slrealtime.Instrument(app.SLRTApp);
addInstrumentedSignals(app.Instrument)
app.Instrument.connectLine(app.DataPlotAxes,"Pos_AX1");
app.Instrument.AxesTimeSpan = 10;
app.Instrument.AxesTimeSpanOverrun = ‘wrap’;
app.InstrumentManager = slrealtime.ui.tool.InstrumentManager(app.BenchTopUIFigure, ‘TargetSource’, app.TargetSelector);
app.InstrumentManager.Instruments = app.Instrument;
elseif value == "velocity"
app.Instrument = slrealtime.Instrument(app.SLRTApp);
addInstrumentedSignals(app.Instrument)
app.Instrument.connectLine(app.DataPlotAxes,"Vel_AX1");
app.Instrument.AxesTimeSpan = 10;
app.Instrument.AxesTimeSpanOverrun = ‘wrap’;
app.InstrumentManager = slrealtime.ui.tool.InstrumentManager(app.BenchTopUIFigure, ‘TargetSource’, app.TargetSelector);

Can I How do I remove the MS sign-on on startup?
It sounds like you are experiencing a situation where your computer is set to require a password at startup. You can remove this sign-in requirement by adjusting your computer’s settings. Here’s how you can do it:
Step 1: Click on the Start menu and select Settings (the gear icon).
Step 2: In the Settings window, choose Accounts.
Step 3: Navigate to the Sign-in options on the left sidebar.
Step 4: Under the “Require sign-in” section, select Never from the drop-down menu.
Step 5: Close the Settings window.
By following these steps, you should no longer be prompted to enter a password every time your computer starts up. Now, you should be able to simply press the Enter or Space bar to quickly access your computer without the need for a password.
If you encounter any difficulties or have further questions, feel free to reach out for more assistance.

How to play video in matlab for computer vision?
I am trying to do object recognition using blob analysis. when i did write the code the video is flickering every second, is it possible to have a video player running without flickering? I have attached my code below. please recommend me any changes

How to associate manually filled cells with cells linked to other excel files?
Hello everyone,
First of all, I’d like to apologize if I made any mistakes. English isn’t my first language.
I have encountered a problem at work and I wonder if you could help me.
I have linked some cells to other Excel files so they can fill themselves according to the cells from those files.
Furthermore, I manually filled some other cells on each line corresponding to the imported cells.
The problem arises when I update the files from which the data is imported.
Indeed, when lines are added to those files, they are also added to my main Excel file (which is good, that’s what I want), but when those lines are added, my manually written data doesn’t move with the cells they were next to originally. As a result, they appear next to cells they shouldn’t be next to. Basically, my whole column of manually written data becomes incorrect.
What can I do to ensure those manually written cells stay with the imported cells so they move together if more lines are inserted in between?
Thank you for your help,
Wiljunow.

Simulink Model to transfer function via simulink and Matlab
hi everyone,
in the picture i uploaded you can see my closed loop model for a dynamic system.
im trying to get the transfer function between the input signal Va to the output signal Phi , while considering all the feedbacks.
when i do it by the model linearizer app or the control system designer i get strange bode plots and wrong transfer functions.
so i would like you to help me understand how can i do it correctly plese.
the seconed question is how can i get the same closed loop transfer function on simulink script by using feedback command.
