I happily had one note for 8 years. One note 2017. Used it offline. All my notes.
Windows 10 put Microsoft 365 on my computer. Tried to sync a bunch of stuff too OneDrive. I said no. Still it made my desktop on one drive. It kept trying to sync documents. A constant nuisance.
This year I tried to save my taxes to my One Note files. I was told they were erased. I couldn't imagine what was going on. They were on my computer, local and private. But no I would have to log into OneDrive and rebuild them if I wanted to use my files. I could see them. But I couldn't open them, I couldn't save new things, I couldn't do anything, unless I logged into OneDrive.
I uninstalled Windows and installed Linux Mint 22.1. I ain't going back no more.
