Hello,
Thank you for posting in the Microsoft Community Forums.
It sounds like you're encountering a few different issues with user permissions and account switching on your Windows 10 device. Here are some steps you can try to resolve these problems:
- User Account Control (UAC) Settings
Sometimes, UAC settings can prevent certain actions even if you have admin privileges. You can try adjusting these settings:
Press Windows + X and select Control Panel.
Go to User Accounts > User Accounts.
Click on Change User Account Control settings.
Move the slider to the lowest setting (Never notify) and click OK.
Try uninstalling the software again.
- Run as Administrator
Ensure that you are running the uninstallation process with administrative privileges:
Right-click on the uninstaller or the program you want to uninstall.
Select Run as administrator.
- Safe Mode
Booting into Safe Mode can sometimes bypass certain restrictions:
Press Windows + R, type msconfig, and press Enter.
Go to the Boot tab and check Safe boot.
Restart your computer and try uninstalling the software in Safe Mode.
- Switch User Issue
If you are unable to switch users:
Press Ctrl + Alt + Delete and select Switch user.
If this doesn't work, try restarting your computer and selecting the correct user account at the login screen.
- Check for Malware
Sometimes, malware can cause issues with user accounts and permissions:
Run a full system scan using Windows Defender or another trusted antivirus program.
I hope the information above is helpful.
Best regards
