The update is distributed by Windows Update and is installed automatically. Its sole purpose is to check whether an unsupported version of Microsoft Office is installed on the system and to notify Microsoft about it.
The program checks if any version of Microsoft Office 2007, 2010 or 2013 is installed on the device. Microsoft Office 2013 is technically not unsupported yet, but it reaches end of support in April 2023.
Microsoft notes on the support page: "This update is intended to help Microsoft identify the number of users running out-of-support (or soon to be out-of-support) versions of Office, including Office 2013, Office 2010, and Office 2007. This update will run one time silently without installing anything on the user's device."
Microsoft makes no mention of it explicitly, but the information about unsupported Office clients is submitted to the company.
