Just putting this out there... a few days ago I needed to do the "monthly" clean up (after three months) so while I was making a backup of our centrally-stored data on the old Linux desktop, I let #Ucheck do its thing on our two Windows laptops, then finished off with a quick Microsoft Store update, CCleaner registry clean and ShutUpWin safety check.
Imagine my utter shock, therefore, when I went to edit an ODS spreadsheet yesterday and was confronted with EXCEL instead of #LibreOffice !!!
Unless Ucheck did it deliberately (seems unlikely) something in Windows Update or WinGet actually *uninstalled #LibreOffice * then *installed #Microsoft365 / #MicrosoftOffice instead*!
It happened on both Windows laptops. That is flabbergastingly low even for #Microsoft... I checked around and there were a couple of other people who complained about the exact same thing over the years...
