Neowin posted a story that WZOR has confirmed that all of the editions of Windows 8 RTM that have leaked over the weekend can now be activated with a workaround

It only took a few days, but all of the Windows 8 RTM editions leaked by AngelWZR have now been cracked, allowing people who have downloaded and installed them to activate Windows, if they know where to look.

The crack bypasses the Microsoft KMS servers which allows for 180 days before it needs to check it against a valid server again, AngelWZR posted the evidence on yfrog showing a customized Start screen. An image (shown above) showing post activation and Windows Experience Index (WEI) had been completed was also submitted to Neowin.

Up until this news, the leaks allowed people to run Windows 8 in "notification mode" which meant that every so often, a reminder would show up telling the user to activate Windows.
