Hi Diplocaulus,
Thank you for your additional clarification on this issue. It's really hard to catch a random event and record a video message.
I will provide you with a more comprehensive system repair scheme.
Visit Download Windows 11 (microsoft.com) and click "Download Now" to download MCT (Media Creation Tool), then download and run the program, select "Create installation media (USB flash drive, DVD or ISO file) for another PC” , and then choose Language, Version, Architecture (if you are not sure about these, choose "Use the recommended options for this PC"), then select "ISO file" in the "Select Media to Use" interface, and then a windows ISO file will be downloaded to your disk (about 4-5GB in size, it is recommended that you choose a non-system disk).
After the download is complete, double-click the ISO file, double-click to run "setup.exe" in the open file explorer, and select "Change how Windows Installer downloads updates" > "Download updates, drivers and optional features", Select "Keep personal files and apps" after accepting the terms of the agreement, then click "Next" > "Install". Then the system will reboot a few times, and then enter the welcome screen.
Disclaimer: Please back up all your important data before performing it.
It is important to stress that this is not a reinstallation of the system. The principle is to download the intact system image file, and then overwrite the system to achieve the purpose of repair. Therefore, you can operate with confidence.
