Windows 10 will be EOL in a year.
These companies will bs you about how eco friendly they are, but they expect you to throw a perfectly fine computer into the trash.

The definition of insanity is doing the same thing over and over again, expecting different results.
The results this time will be same as it was for users last time. Or you finally give up on the abusive practices of this vendor, and use something that respects your efforts and choices. But, there are still a TON of older hardware running those older OSes. Security and software updates be dammed.
Windows 10 actually breathed new life into some older PCs. Sad to see them cut compatibility so suddenly and without significant advantages.
