Hi
I never experienced limited usage before registering Windows.
I don't know whats going on here, I've never used Vista but everything else has you connected before you get to the desktop the first time. It usually downloads drivers while it's installing.
I'm not sure what you mean by test copy?
A Google search didn't come up with anything called that.
Can you download the driver install on another computer and install it from a CD?
How about downloading an ISO for Windows 7 and installing it in place of Vista since you don't have a registration for Vista anyway.
Or if you want to, you could download and install Windows 8 and not have to worry about registering it at all for the rest of the year.
I'm running Windows 8 and it really runs better then Vista or 7 for gaming and it will install ready to go as far as drivers.
