Am trying to remove MS 365 (from my acct) prior to end of 30 day trial, determining that it (excel 2021) corrupts my Excel 2010 file. Suspect Windows wants to upgrade my downloaded Office 2016 (to 2021) even though MS office 2021 and ms 365 apps have been uninstalled (Office 2016 is in place). (Microsoft account still shows registration keys for ms 365 and Office 2021, which I had previously tested unsuccessfully.)
