Manually Uninstall Office Professional Plus 2021

Use this manual removal method when the Microsoft Support and Recovery Assistant fails or the application is missing from the Windows App list.

Since the automated Fix It tool may no longer be available or is throwing an error, you must follow Microsoft's official manual removal process. This requires manually deleting specific installation files, folders, and registry keys associated with Office 2021.

1
Remove Office Installation Folders

Open File Explorer and navigate to 'C:\Program Files' and 'C:\Program Files (x86)'. Locate the 'Microsoft Office' and 'Microsoft Office 15' folders, right-click them, and select 'Delete'.

2
Delete Scheduled Tasks

Search for 'Task Scheduler' in the Windows 11 Start menu. Open it, expand 'Task Scheduler Library', click on 'Microsoft', and select 'Office'. Delete all tasks listed in this folder.

3
Remove Office Registry Keys

Press Windows Key + R, type 'regedit', and hit Enter. Carefully navigate to 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office' and 'HKEY_CURRENT_USER\Software\Microsoft\Office', then delete these keys to wipe the remaining configurations.

4
Restart Your Computer

Once all files and registry keys are removed, restart your Windows 11 PC to finalize the manual uninstallation process.

Registry Warning: Editing the Windows Registry can cause system instability if done incorrectly. It is highly recommended to right-click and 'Export' a backup of your registry before making manual deletions.

Frequently Asked Questions

Why is Office Professional Plus 2021 not showing in Windows 11 Apps and Features?

This typically occurs if the Office installation became corrupted, was partially uninstalled by a third-party cleaner tool, or was installed using specialized deployment tools that mask it from the standard Windows application list.

What should I do if the Microsoft Support and Recovery Assistant redirects to Get Help?

If the automated tool fails or displays an error, the Fix It tool has likely been deprecated for your specific build. You must manually remove the Office program files and registry entries to clear the software.

Can I reinstall Office 2021 after manually uninstalling it?

Yes. Once the corrupted version is completely removed, you can reinstall Office 2021 by logging into your Microsoft account associated with your perpetual license and downloading the setup files again.
