Prevent Office 365 Installation at New User Logon

[davidjohnson]

Office 365 (click to run) installs each time a new user logs on to the laptop. Our enterprise has licensed Office 2019 so we do not want the click to run installation. Can this be prevented?

Every time a new user logs into the same PC, it's basically performing setup again for that new use account.  IF the PC came with a trial version of Office 365 (which is my guess) then of course, it will attempt to configure that afresh for each new user.

What you most likely need to do is start over by  logging in as the original user and removing the CTR version of Office 365 -- using these instructions: https://support.office.com/en-ie/article/uninstall-office-from-a-pc-9dd49b83-264a-477a-8fcc-2fdf5dbf...

Then, you will need to reinstall Office 2019.

After that, new users should not longer get prompted regarding Office 365.

We uninstall Office CTR as the first user to log in. Office 2019 installs and runs fine. The user is never prompted about Office CTR. It simply gets installed side-by-side each time a new user logs in. HP WorkWise and HP Sure Click also get reinstalled with each new user.

Sorry, then you will have to contact Microsoft about the Office 365/2019 issue as we have no way to fix that problem.

The solution is to remove some or all of the provisioned apps. The process is described here: https://4sysops.com/archives/remove-provisioned-built-in-apps-in-windows-10/
