Here is a neat little hack to use Microsoft’s Windows Vista OS for 4 months without a key, activation, registration, nothing!

Install or upgrade Windows Vista, do not enter a product key and get 30 days free like everyone else. On the 29th day, click Start, Run, and type in: slmgr -rearm

This will give you another 30 days and repeat this step on the 59th day. From what I have been told this works for 4 months only and hopefully by then you’ve delivered enough newspapers to buy yourself a copy of Microsoft Windows Vista.
