    To completely remove Microsoft Teams remnants from your Windows server, you can follow these steps:

    1. Uninstall Microsoft Teams: Ensure that Microsoft Teams is properly uninstalled. You mentioned you have already done this, but it's good to perform a clean uninstall to make sure no remnants are left behind.
      • Go to Control Panel > Programs > Programs and Features.
      • Find Microsoft Teams in the list, right-click it, and choose Uninstall.
    2. Remove Teams Directory: After uninstalling, check and manually remove the Teams directories.
      • Navigate to %LocalAppData%\Microsoft and delete the Teams folder.
      • Also, check %AppData%\Microsoft and delete the Teams folder if it exists.
    3. Clean Up Registry Keys: If the path mentioned in the scan result (HKEY_USERS/S-1-5-21-4109376241-3782159086-2763052967-1002/SOFTWARE/Microsoft/Windows/CurrentVersion) does not exist, you'll need to manually search for and delete any related registry entries.
      • Open Regedit (Registry Editor) by typing regedit in the Start menu search bar and pressing Enter.
      • Navigate to HKEY_CURRENT_USER\Software\Microsoft and look for a Teams folder. If found, delete it.
