Hi Norris,
If the Delete option is greyed out, it’s usually because the profile is still in use, even in the background. Try restarting the PC and make sure you're logged in with a different admin account you can't delete the one you're currently using.
If that doesn’t work, boot into Safe Mode or use Command Prompt run it as admin and try this command net user [username] /delete
As for the Office issue: The expired Office 365 message likely comes from a Microsoft Account that was once signed in. The “2024 Pro Plus” license showing in the apps is separate and valid.
To clean it up:
- Go to Settings > Accounts > Email & Accounts and remove any linked Microsoft accounts.
- In Office apps, go to File > Account and sign out of any expired accounts.
Hope that helps!
