How to Fix Word/Excel Stops Working Suddenly

If Word or Excel crashes or becomes unresponsive during use, or when you try to create a new document or spreadsheet, you can try uninstalling KB5002700 to fix the issue. However, this update does not appear in the Windows Update history, so it is not the same as uninstalling a regular Windows update. To remove it, you need to use the Command Prompt. Here are the steps.

Process 1. Determine the GUID of the Office version

Step 1. Press the Windows + R key combination to open Run.

Step 2. Type regedit in the text box and press Enter.

Step 3. Type the following location in the address bar and press Enter.

For 32-bit OS:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

For 64-bit OS:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall

Step 4. In the Uninstall folder, locate the GUID for Office 2016, which should start with a brace ({). You can verify the correct GUID by checking the DisplayName field in the right panel. The name should be something like Microsoft Office Professional Plus 2016.

Finally, note down the correct GUID.

Process 2. Determine the GUID of the update

Step 1. Visit the Microsoft Update Catalog page for KB5002700 and click Download next to the update version that matches your system specs. In the new window, click the blue link to get the package file.

Step 2. Once the update file is downloaded, open Command Prompt by using the search box. After that, type cd C:\Users\YourUsername\Downloads (replace the location with the actual path where the update file is located) and press Enter.

Step 3. Run this command to extract the MSP file of the Office update to the C:KB5002700 folder: mso2016-kb5002700-fullfile-x64-glb.exe /extract:C:\KB5002700.

Step 4. In the C:\KB5002700 folder, right-click the MSP file, select Properties, and go to the Details tab to copy the GUID number or revision number.

Process 3. Delete the GUID to uninstall the update

In Command Prompt, execute the following command to remove KB5002700:

%windir%\System32\msiexec.exe /package {Office GUID} /uninstall {Update GUID} /qn

Finally, restart your computer and check if Office 2016 works well.
