I paid for Windows 10 once. It was actually quite good at the beginning but then, through updates, Microsoft turned into intrusive garbage of a system pushing their shitty services and behaving like my laptop was their property. I'm still ashamed of that purchase. If you really need anything from Microsoft - pirate it.
I was forced to upgrade my work laptop by my company, and I basically lost two full days of productivity because of how truly shitty the new OS is. Still not back to normal productivity, and it’s been two weeks. Definitely felt like a scam…
