The crack bypasses the Microsoft KMS servers which allows for 180 days before it needs to check it against a valid server again, WZOR posted the evidence on yfrog showing a customized Start screen.
The first leak came a day after Microsoft handed over Windows 8 RTM bits to OEMs, and was the Enterprise "N" edition which is sold in Europe without Windows Media Player. Then yesterday four more ISOs leaked, first of all, both x86 and x64 versions of Enterprise, followed later by the Professional version of Windows 8 which indecently replaces the "Ultimate" version of Windows. These were said to be untouched images directly from Microsoft, whereas the first leak was a modified image with an embedded volume license key.
Obviously we won't post details of that process here, and we would ask that people don't do so in the comments either.
