How can I gracefully leave Microsoft Windows for ever?

Dear Microsoft,

In light of your most recent update, which destroyed data on a separate hard drive to my operating system - damaging a video I spent hours on creating for YouTube (and possibly countless other files), and after seeing the AI spyware that will be included in the next feature update, I would like to know what is the best way to gracefully leave the Microsoft ecosystem.

I do not want to be spied upon any more. I do not want AI forced upon my computer to slow it down to a crawl. I do not want all of my precious memory taken up by needless compute especially at its current retail prices. I do not want subscription cloud services to steal my hard earned money away from me.

I will be seeing a new operating system. They do not pry into my private life. They do not push me into purchases of things I do not need. They do not spy on what I type, or what I watch, or what I edit, or what I listen to. Although they can be a bit distant and old fashioned, they dress up nicely in a tuxedo.

Goodbye Windows, although I will see you in passing, and occasionally borrow a cup of sugar or two while I slowly distance myself, you piled on the straw that broke the camel's back. I bought an i9 for quick responses, not for you to rape it for personal information and bog it down to an AT/XT 8MHz while destroying my precious data with your updates and automatic "disk repair".
