I own an Asus laptop with Windows 7 installed, but I am going to be building a new gaming rig very soon. If you want to run two versions of Windows, you have to buy two licences. No, Microsoft is not giving away copies of Windows 10, just offering to upgrade existing licences for Windows 7/8/8.1 to Windows 10 for free.

I’m told the free upgrade is only for one year, and after that you have to pay £80 for it. I’m thinking of upgrading from Windows 7 to Windows 10.
