How to Completely Uninstall Microsoft Office Using the Office Scrubber Tool

Navigate to the official Microsoft Support website to download the Office Scrubber tool. This ensures you get the latest version directly from Microsoft.

Open your web browser and go to the Microsoft Support page. Search for "Uninstall Office from a PC" or navigate directly to the Office uninstall support page. Look for Option 2 under the Click-to-Run or MSI section.

Click the Download button to save SetupProd_OffScrub.exe to your Downloads folder. The file size is approximately 50 MB.

Now install the Office Scrubber tool on your system. This process requires administrator privileges to properly access system files and registry entries.

Locate the downloaded SetupProd_OffScrub.exe file in your Downloads folder and double-click it to begin installation. When prompted, select "Open File" or choose the program from your download list.

Windows will likely display a User Account Control prompt asking "Do you want to allow this app to make changes to your device?" Click "Yes" to proceed with administrator privileges.

The installation wizard will appear. Click "Install" and wait for the installation to complete, which typically takes 2-3 minutes. When the license agreement page appears, select "I Agree" to continue.

Before running the removal process, ensure all Office applications are completely closed and your work is saved. This prevents data loss and allows the tool to access all Office files.

Save and close all open documents in Word, Excel, PowerPoint, Outlook, and any other Office applications. Use Ctrl+S to save documents quickly, then Alt+F4 to close each application.

Open Task Manager by pressing Ctrl+Shift+Esc and check the Processes tab for any remaining Office processes. Look for processes like:

WINWORD.EXE (Microsoft Word)
EXCEL.EXE (Microsoft Excel)
POWERPNT.EXE (Microsoft PowerPoint)
OUTLOOK.EXE (Microsoft Outlook)
MSPUB.EXE (Microsoft Publisher)
MSACCESS.EXE (Microsoft Access)

If you find any Office processes still running, right-click them and select "End task".

The Office Scrubber tool will automatically scan your system and present options for which Office versions to remove. This step is crucial for targeting the correct installation.

When the tool launches, it will display a list of detected Office versions. You'll see options like:

• Office 2007
• Office 2013
• Office 2016
• Microsoft 365 (Office 365)
• All of the above versions

If you're unsure which version you have installed or suspect multiple versions, select "All of the above versions". This option performs a comprehensive system scan but takes longer to complete.

For specific version removal, choose the exact Office version you want to uninstall. Click "Next" to proceed.

Before the actual removal begins, you must confirm that you've completed all preparation steps. This prevents interruptions during the removal process.

The tool will display a checklist confirmation screen. Check the box next to "I have saved all my work, closed open Office applications and stopped any other setup program".

Click "Next" to begin the removal scan. The tool will now start scanning your system for Office files, registry entries, and related components.

During the scan, you'll see a progress indicator. The duration varies based on:

• System performance and disk speed
• Number of Office versions installed
• Amount of Office-related data on your system

Typical scan times range from 5-15 minutes for single installations, up to 30 minutes for comprehensive "all versions" scans.

Once the scan completes, the tool will remove all detected Office components. This includes files, registry entries, shortcuts, and license information.

The removal process runs automatically after the scan finishes. You'll see status updates showing:

Removing Office files...
Cleaning registry entries...
Removing shortcuts and menu items...
Clearing license information...

The tool removes components from multiple locations including:

• C:\Program Files\Microsoft Office
• C:\Program Files (x86)\Microsoft Office
• %APPDATA%\Microsoft\Office
• %LOCALAPPDATA%\Microsoft\Office
• Windows Registry Office entries

When removal completes, the tool will prompt you to restart your computer. This restart is essential to finalize the removal of system-level components and registry changes.

After restarting, your system will complete the Office removal process and may present options for reinstalling Office. Handle these prompts based on your intentions.

Click "Restart Now" when prompted by the Office Scrubber tool. Your computer will restart and complete the final cleanup steps during the boot process.

After restart, the tool may automatically launch and display a prompt about reinstalling Office 365 or Microsoft 365. You have two options:

• Select "No" if you don't plan to reinstall Office
• Select "Yes" if you have an Office installation file ready and want to perform a clean reinstall

If you choose not to reinstall, the tool will close and the removal process is complete.

Perform comprehensive verification to ensure Office has been completely removed from your system, including all files, registry entries, and shortcuts.

Check multiple locations to confirm complete removal:

1. Programs and Features:

Open Settings > Apps > Apps & features (Windows 11) or Control Panel > Programs > Programs and Features (Windows 10). Search for "Microsoft Office" or "Office" to verify no Office entries remain.

2. File System Check:

Open File Explorer and navigate to these locations to confirm they're empty or don't exist:

C:\Program Files\Microsoft Office
C:\Program Files (x86)\Microsoft Office
%APPDATA%\Microsoft\Office
%LOCALAPPDATA%\Microsoft\Office

3. Start Menu Verification:

Click the Start button and look for Office applications. No Word, Excel, PowerPoint, or other Office apps should appear in your applications list.

4. Registry Check (Advanced):

Press Win+R, type regedit, and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office. This key should not exist or be empty.
