Rename the application

Renaming an executable file will prevent it from being executed. Microsoft Word, Excel, PowerPoint, OneNote, Publisher and Access are some examples of programs that use.exe files. If you rename one of those files, Windows won’t recognize it anymore and won’t run it. However, you can still open the original file in Notepad or another text editor.

This trick works for all versions and editions of MS Office 2016.

If you’re trying to install a different edition of the software, you’ll probably encounter a prompt asking whether you want to replace the existing installation. Click “Yes.”

You should never renumber applications unless you check if there’s any other older version of the same program already installed.

Disable the Scheduled task

To disable the scheduled task, you must open Task Scheduler. Click Edit next to Action and choose Disable.

Disable the scheduled tasks with Powershell

Then type powershell and press Enter. This opens up PowerShell prompt window. Type the following command and press Enter:

Set-ItemProperty -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce -Name DisableTask -Value 0

Then type exit and press Enter. You are done. Now you can enable the Office feature update again.
