I'm building a new pc and i dont know what OS to use. I know Windows 10 is out but what should i get before upgrading to 10. Windows 7 or 8, which version.
If you're willing to upgrade/spend some time updating Windows7/8.1 to get the free 10 upgrade, then by all means do that and then perform a fresh install (this is if you can find 7/8.1 cheaper than 10). If not, then just go for 10. Even if it's 5-10 dollars more, it's worth saving the time.
