Activate Windows 8 Build 7955
Microsoft is going to recycle the product keys that are used to activate the Windows 7 Beta for Windows 8 Beta? Apparently, no hack nor crack is required to activate Windows 8 M2 (pre-M3) Build 7955. To activate an installed Windows 8 Build 7955 system, the trick is to just use a free product key provided by Microsoft during Windows 7 Beta.
Microsoft actually only provided 10 product keys – 5 for 32-bit (x86) and 5 for 64-bit (x64) – for the whole world to activate Windows 7 Beta. In other words, these free product keys can be used by unlimited activation. But it’s unknown why Microsoft still does not block or blacklist the Windows 7 Beta product keys.Hence the same can be used for activation.
Windows 7 Beta 64-bit Product Key
[ These keys are not needed now as the Activation for the build has expired]
Windows 7 Beta 32-bit Product Key
[ These keys are not needed now as the Activation for the build has expired]
Unfortunately, Windows 8 Build 7955 activated with the product keys above does not unlock any hidden features, as the Windows 8 activation system generates a special hash ID which determines which a feature is available from the product key used to activate the system. Thus, these supposedly expired product keys cannot unlock the features.
Note that it’s not necessary to activate the system to unlock most hidden locked Windows 8 features. After installation, there is 30 days activation grace period to enjoy the system for free.
To activate Windows 8 Build 7955, go to Control Panel -> Action Center -> Genuine Center. Click on Enter a new product key button.
