My desktop PC and laptop share the same Windows account (or whatever it's called - same PC name/email). I haven't yet been able to download Windows 10 on my laptop, but I guess that's because Microsoft is apparently releasing it wave by wave. Once I am finally able to download Windows 10 on my laptop, will it upgrade my PC too? My PC doesn't have that "Get Windows 10" icon. It was there about a month ago and for some odd reason it disappeared. I'm 100% sure it's compatible for Windows 10 as well.
