Windows 12 could see a substantial system redesign in order to include a more AI-centric user experience. The start button could thus be replaced with Copilot AI, which is already available as a preview version in the latest Windows 11 update.
A few weeks ago when they made the search bar come back after I had told it to go away I switched to Linux. It's weird the small annoyances that add up. It's great so far. With KDE for the desktop environment, you can make it look however you want, including almost identical to any version of windows you want. It's really quite usable, and generally I'm already faster and more comfortable with it than I was with windows.
