I am going to eventually use Linux (although need help with a good option for gaming and video library use), but I was curious how long I could use Windows unregistered for? What are the limitations of it not registered?
U can use it how long you like. There are only some settings, you cant cange (but only in the settings, when you use the old control panel, you can sometimes still change them). Biggest issues for a standard user would probably be no background image and the watermark.
