Windows 7: Using my current copy of Win7 on a new PC build

Using my current copy of Win7 on a new PC build

I would like to take the copy of Win7 Ultimate I use now, and install it on a new PC build I will be getting in a couple of weeks.

As soon as I can, I will get a new copy of Win8.1, but I am wondering if I can use the old OS on a new PC, before the 30 days (before activation) is up, and install the new OS on it before then, as an upgrade or full version?

I'm assuming this can be done, as I had a housemate move in years ago who didn't have an OS (because his WinXP installed fatally messed up during updating) and so he asked for my WinXP disc at the time and kept reinstalling it every month - he just didn't "activate" it. He later got his own copy.

I would assume if it's possible, then it's not legal, but then I'm suggesting a temporary measure and won't stick with it.

Anyone know?

Hello Foebane,

You will need to install a retail copy of Windows on the new PC, but yeah it's perfectly legal to do so as a 30 day trial without activating.

Personally, I would recommend to clean install Windows 8.1 instead of upgrading from Windows 7. This way you won't have to worry about any potential issues from an upgrade.
