Random CMD prompt opens randomly and closes.

For the past couple of months before I installed windows 11 and was on windows 10 a cmd prompt would open, interrupt Fullscreen then close a second later. The name of the cmd prompt was a file directory to something in my AppData folder but checking for the file it doesn't show up even when looking for hidden files. It has a random name which is just random characters and sometimes it stays on long enough for me to see it says something like .NET Framework. This is an annoying issue as I haven't been able to use Fullscreen for things like games because it closes it once it opens. I have ran multiple full scans with windows defender and malwarebytes to no result. I have tried to screenshot it but it closes too quick.

 

Deleting Hiberfil & Pagefile

You would have to move your Page File to a different drive to get rid of that file, however you can make is smaller by adjusting the size in Windows.

To get rid of Hyberfile.sys you need to disable hibernation by doing the following:

• Click Start, and then type cmd in the Start Search box.
• In the search results list, right-click Command Prompt, and then click Run as Administrator.
• When you are prompted by User Account Control, click Continue.
• At the command prompt, type powercfg.exe /hibernate off, and then press ENTER.
• Type exit and then press ENTER to close the Command Prompt window

Then you can delete the hyberfile.sys file.
