Every single time it updates, which it forces on me I come back to add to buy Office 365 even if I already have it. On one computer the File Manager is slowed to a crawl, the image viewer slows to a crawl if I hit left or right arrow keys. The built-in antivirus has a feature to send “suspicious” files to Microsoft, with zero audit trail of what it sends over, and its on by default.
The various UI inconsistencies, theres weird XP goop mixed with the modern UI.
I tried to make a new user account one time and it told me I couldnt because I needed to use another feature within Windows to do so, when I went to do so it told me I needed to either use the same feature that led me there (if I remember correctly). It was ridiculous.
Hot, garbage since 2022.
Not to mention all the absurd telemetry. Everything you type into the start menu goes into a Microsoft backend. Everything, every time. Idk how people can have so much of their data constantly going to a Microsoft backend without being upset. Goes back all the way to Windows 8 or 10 btw.
