Windows vista always updating
If you plan on building your own computer instead of buying one that comes with Windows 10, you’ll need to buy a Windows 10 license anyway.
So, if you are sure you’re building your own computer, you could buy a Windows 10 license now, install Windows 10 on your Vista computer, and then remove Windows 10 from your old computer when you get a new PC and use the Windows 10 license on the new computer.
Those old Windows Vista PCs can make good Linux PCs, too.
Yes, if Microsoft offered Windows 10 for free — or even for a small fee — to Windows Vista computer, it would be worth the upgrade.
But, even then, you’d probably want to consider replacing that aging hardware anyway.
There’s a good chance you can get a laptop or desktop PC that comes with Windows 10 for just a few hundred bucks.
At 9 just for a Windows 10 license, it’s really not worth the upgrade unless you have a big, beefy, powerful PC that for some reason still runs Windows Vista.
