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.
Editor's Update: There seems to be some confusion about the above link to the Microsoft store. It was and is indeed genuine. We've changed the link to direct to the store.microsoft.com domain instead of the store.microsoft-ppe.com that we originally had in the story, which is still a Microsoft domain but not their normal store link. We apologize for the confusion caused.
