I'm really liking Windows 10 so far, nowhere near as annoying as 8 was, it seems to be working well so far, although the installation process was a little annoying as I wanted a fresh install, so had to upgrade, then make an installation disk, then re format and install again, it's all on now though and activated, completed Dragon Age 2 last night running Windows 10, no problems occurred.
I did notice one problem very quickly though, when I tried to run my Gigabyte driver disk, I got the following message: This version of Xpress install does not support Win 98/ME, Open device failure, so I can't install my driver disk, might have a look on their website maybe.
