Better hurry up if you want to download the Windows 7 beta, since Microsoft is only allowing the first 2.5 million of you to try it out. Those of you with fancy TechNet and MSDN connections can grab it now; everyone else will have to wait till tomorrow, Friday, January 9.
You should note that, in order to use the Windows 7 beta you’ll have to be upgrading from Vista SP1. So if you’re one of those “Vista sucks~!” people you’ll have to figure something out.
And, obviously, you won’t want to be running this as your main operating system.
The beta will expire in August.
