hi there.
based upon the information provided.
In a typical Windows 10 installation, you should not see multiple "TEMP" folders within the "C:\Users" directory. The "C:\Users" directory is the parent directory for user profiles on Windows, and it should contain one folder per users account.
but If you're seeing multiple "TEMP" folders within "C:\Users," it's possible that some temporary profiles or leftover folders were not properly cleaned up.
Press windows key and r
and type %temp% and hit enter
and then select all and clean.
Use Disk Cleanup: Run the built-in Disk Cleanup utility in Windows to clean up temporary files and folders. You can access it by typing "Disk Cleanup" in the Start menu search bar and selecting the application. Once launched, select the drive where the "C:\Users" directory is located (usually the C: drive), and select the options to clean up temporary files and system files.
check if there is any malware or virus affected the pc.
And see if it helps,
Thank you
