Uninstall Office 365 Click-To-Run Updates

There are cases where you want or need to uninstall an Office update. Office 365 installations use a different update than the old Office 2013 & 2016 installations. Where the old installations are a point in time installation, click-to-run always downloads the latest version and then runs the setup. You can revert to an older version but its different than in the past where you could just uninstall an KB update.

Steps

Step 1: Check build number and find previous build number

In one of your office programs go to the options menu and go to Office Account. Find your current and previous version on the Microsoft website: Update history Office365 ProPlus by date

Step 2: The Office 365 installations are automatically updated in the background, we will first need to disable automatic updates. Go in any Office application to:
File > Office Account > Update Options > Disable Updates

Step 3: Type the command that applies to your version of Office and/or Windows in a Elevated command prompt (Run CMD as Administrator)

Office 2016 / 2019 / 365
cd %programfiles%\Common Files\Microsoft Shared\ClickToRun\

Office 2013 on Windows 32-bit
cd %programfiles%\Microsoft Office 15\ClientX86\

Office 2013 on Windows 64-bit
cd %programfiles%\Microsoft Office 15\ClientX64\

Step 4: Revert to the previous version by entering the following command:
officec2rclient.exe /update user updatetoversion=<build number>

After hitting Enter there will be an Office update box. You can verify your version by going to your office account in the options menu.

What next?

In step 1 we disabled automatic updates. Now that it is disabled you will need to keep an eye on new updates your self. Always re-enable automatic updates at the earliest opportunity.
