@itsfoss For me it was Windows 11. Like, just everything about 11.
10 was already horrible. I pretty much need third party solutions or a heck of a lot of time tracking down registry entries to keep it from basically sending MS my social security number and a feed of my bathroom. 11 is tough even to clean with third party tools and registry entries and judicious blocks at the router firewall...
Then they started backporting some of the bad stuff to 10 along with Copilot. I'm scared even to let my systems update anymore. MS may be less safe to trust than random hackers on the Internet.
And now they're trying to force out Recall even after everyone said no so hard they had to pretend to change their minds once before. I'm done. I'm just done. I finally made the true switch.
