With this change, I have decided to accept the insecurity of not updating and stick with 10. The only thing I do on Windows is ensure my FOSS is cross-platform.
I must say it's quite refreshing to not have to deal with Microsoft's user-hostile nonsense. No shenanigans with required accounts, no ads, no preinstalled bloatware. My OS is made to serve me and my needs, not to eke out extra profits. Ironic that the free option is better at serving me than the paid option, these days.
The sad part is, I like Windows. Or at least I used to. I've never been a "Windoze sucks, I hate M$" guy. Time was that it was genuinely a well made operating system that did its job well and got out of the way. But those days are long since gone. I hope that someday Microsoft gets their act together and starts caring about making a quality product again.
I refused to "upgrade" past Windows 7.
When Windows 7 went EOL, I installed Linux. I've never looked back.
I just use Windows to build and test my FOSS on it.
