I just installed Win11 on a work computer last week, and there were at least 3 screens of the installer trying to push o365 or one drive.
Then you have the start menu where if you look for a software, 90% of the menu is an ad trying to push you a software. At the bottom, you have your search results.
And then there is the pop ups on the bottom right of the screen trying to sell you Candy Crush or another bullshit software.
