As we reported earlier today, Microsoft would offer both Windows 7 Home Premium and Professional at a pre-order discount price of $49.99 and $99.99 respectively starting June 26th and going through July 11 while supplies last.
But it looks like you don't have to wait any longer, the Microsoft Store is now taking Windows 7 pre-orders at the discounted prices. Users can either pre-order Windows 7 as a download, a download plus a disc, or just a disc. People are reporting that their Windows Live ID's aren't being accepted if they try to log in, but if they create a new account with their e-mail address the order does go through.
Also, for those wondering if you're able to "clean install" with a Windows 7 upgrade disc, Paul Thurrott is reporting that you will be able to like you could with a Windows Vista upgrade disc.
