Boy, the good ole days are gone when it comes to Windows. I am posting just to help anybody that doesn’t know. This is like a creepy wire tap. If you are actually using Windows 11, make sure to disable and or reduce telemetry in Windows 11 (Privacy). If that actually helps, I am sure there are more ways they send data back but the video link is a simple how to for the telemetry. Here is more info: https://www.youtube.com/watch?v=Wtg_s1GQiMU
The office problem. I moved over a long time ago. Word at that time couldnt handle large documents, and excel was a pain in the ass for the csv data we were getting at the time.
Either deal with that pain over a few weeks, or deal with that pain forever! Maybe the fork of onlyoffice will do what you want.
If its only office you can just run windows inside of linux without issue and have it launch the office application when needed using winapps. https://github.com/winapps-org/winapps
Personally I just keep windows in a docker container for that ultra rare time I need windows.
