You want to take a look at Microsoft office, my bad Microsoft copilot 365...

You can't even select a cell on notepad without a freaking copilot button pooping up every single time. Same on word, that's maddening !

You could argue that windows isn't Microsoft copilot 365, but then, why do people even use windows ? It's always because of the office, my bad, copilot 365 suite.

You can also get rid of both of them very easily with O&O Shutup 10++ (or any of many other GUIs or scripts designed for the same purpose of decrapifying Windows). I toggled off Copilot and Onedrive and haven't seen either in all the years I've been using Windows 11.
