Can someone help me upgrade a system I've recently inherited.. believe it or not I've never changed/updated an OS.
It's currently running Windows 7 x64 Ultimate but isn't activated, I do have a genuine Windows 8.1 Standard licence key though.
TBH, as a Windows user myself (flame me now), I'd stick with Win7. No need to worry about 8.1 or 10. I had no choice* when I bought my laptop - it was Win8.1 only (I did ask). I've got used to (and like) it, but I'd still rather 7.
* I know, I
could uninstall Windows and go with a free OS like Linux, but I code in GLB, which is only available for Windows and it's my only pc.
