GWX
An annoying application for Windows 7 and Windows 8.1 that force upgrades computers to Windows 10, regardless if the user wants it installed or not. It is typically difficult to remove the operating system and restore the previous one after it's installation, and sometimes can break during installation, leaving your computer stuck in an interin loop between your previous Windows install and Windows 10, and by extension unable to boot.
Person 1: Why did my computer get upgraded to Windows 10? I did not ask for that!
Person 2: Oh, yeah. Microsoft recently decided to pull a GWX on millions of people.
