Out of the blue I will get the cmd.exe screen pop up and in a split second it's gone. I "think" it's the cmd screen. How would I go about finding out what it is exactly and why it's happening?

Here are a few steps you can take to figure out what's causing the cmd.exe screen to pop up and disappear:
  1. Check Task Scheduler: Sometimes, scheduled tasks can trigger the Command Prompt to open briefly. Open Task Scheduler by pressing Win + R, typing taskschd.msc, and hitting Enter. Look for any tasks that might be running at the time you see the cmd.exe screen.
  2. Run a Full System Scan: It's possible that malware or a virus is causing this behavior. Run a full system scan using your antivirus software to rule out any malicious activity.
  3. Check Startup Programs: Some programs set themselves to run at startup and might be causing the cmd.exe screen to appear. Open Task Manager by pressing Ctrl + Shift + Esc, go to the Startup tab, and disable any suspicious or unnecessary programs.
  4. Use Process Monitor: Download and run Process Monitor from Sysinternals. This tool can help you track what processes are being created and might give you a clue about what's causing the cmd.exe screen to appear.
  5. Check Event Viewer: Open Event Viewer by pressing Win + R, typing eventvwr.msc, and hitting Enter. Look for any events around the time you see the cmd.exe screen that might indicate what's causing it.
If you follow these steps, you should be able to pinpoint the cause of the cmd.exe screen popping up.

As TraderGary mentioned, Process Monitor can help a lot here, but it's a bit noisy. There's a filter for ProcMon in my post here to help filter out a lot of the noise and just show processes starting and stopping.

Hasn't this been mentioned a long time ago? I sometimes see cmd open two or three times on my other laptop (regular W11 build). It doesn't always do it and it's all over in the blink of an eye. It is like 'open/close, open/close, open/close and it lasts in total for around 1 second or less for all three instances one after the other.

I know I've read about this before and I don't recall any explanation or cause.

The causes can vary. Each machine needs to be looked at, depending on the owner's tolerance for annoying things. :)

check task scheduler and see what all is running as scheduled.

is this when you first login or periodically or when a certain process is taking place (are you doing the same thing when it tends to happen)?
