Microsoft has made OneDrive slightly more annoying for Windows 11 users. Quietly and without any announcement, the company changed Windows 11’s initial setup so that it could turn on the automatic folder backup without asking for it.
Now, those setting up a new Windows computer the way Microsoft wants them to (in other words, connected to the internet and signed into a Microsoft account) will get to their desktops with OneDrive already syncing stuff from folders like Desktop Pictures, Documents, Music, and Videos. Depending on how much is stored there, you might end up with a desktop and other folders filled to the brim with shortcuts to various stuff right after finishing a clean Windows installation.

Just further confirmation that Windows 11 is not ready for the desktop.
