Microsoft has recently started the rollout of a mysterious update that some people were afraid to install. Update KB5021751, which went live in mid-January, was listed as aimed at Office 2007, Office 2010, and Office 2013 users.
Its role was simple, Microsoft said: KB5021751 was only supposed to help the company determine the number of users who are still running out-of-the-date Office versions, but at the same time, also identify the devices where editions of the productivity suite that would soon be retired are still installed.
“This update is intended to help Microsoft identify the number of users who are running out-of-support (or soon to be out-of-support) versions of Office, including Office 2013, Office 2010, and Office 2007.
