After installing Windows 7, and before activation, the operating system will run in an Initial Grace Period license status for 30 days. When this grace period expires, users can rearm Windows 7 for an additional 30 days, and do this up to 3 times, effectively allowing the OS to run legally for 120 days without a genuine product key.When a user uses up all three available rearms, the only option left is to enter a genuine product key to activate Windows 7, or leave the operating system in a crippled, non-genuine state. Users will then be subjected to certain annoyances such as black desktop background, repetitive notification messages stating that this copy of Windows is illegal or counterfeited, and a reminder to register the software at login.Through a Windows Product Activation (WPA) vulnerability that Microsoft introduced in Windows 7, it is possible to reset the remaining rearm count back to 4. There is no limit to the number of times that the rearm count can be reset, meaning that a user could theoretically run an unlicensed copy of Windows 7 forever, without the need for proper activation, and without applying any activation hacks.This WPA vulnerability is related to a WPA registry key which contains the ‘Last Rearm Time’. When the WPA registry key is deleted, the whole licensing status of Windows 7 is re-initiated to the Initial Grace Period as if Windows 7 has just been installed.

The deletion of the WPA registry key is achieved via the following command:reg load HKLMMYSYSTEM “%dp0WindowsSystem32configsystem”reg delete HKLMMYSYSTEMWPA /freg unload HKLMMYSYSTEMGiven the importance of this WPA registry key, Microsoft has locked it (and its sub-keys) from been modified or deleted in a normal user session. The only way to run this command is within the WinRE (Windows Recovery Environment) or WinPE (Windows Preinstallation Environment).In our managed environment, this method of rearming Windows is ultra handy in our SOE creation, in that we do not have to keep starting from scratch when we run out of rearms. This ‘hard’ rearm reset gives us one less thing to worry about if we need to tweak anything in our images.To perform this ‘hard’ reset; create a batch script file with the following commands:.

reg load HKLMMYSYSTEM '%dp0WindowsSystem32configsystem'reg delete HKLMMYSYSTEMWPA /freg unload HKLMMYSYSTEMSave the file as delwpa.bat on drive C: at the root folder level. For example, C:delwpa.bat.

The script didn’t work but it deleting the entry manually from did.boot winperun regeditselect HKEYLOCALMACHINEFile, load hiveopen file: c:WindowsSystem32configsystem (where c = your HDD)it will ask you for a name, this is just a temporary reference to the hive, type in whatever (eg SYSTEM-LOCAL)expand HKEYLOCALMACHINESYSTEM-LOCALdelete WPAReboot.When I did this, the windows activation status was “not available” until I registered my key using the slmgr /ipk command, then it changed to ‘3 days to activate’ and slmgr /dlv showed a rearm count of 5. I did the following to reset the re-arming process:1- Run regedit, it will open the Registry Editor2- On the left of registry editor, expand the following to reach your required file HKEYLOCALMACHINE SOFTWARE MICROSOFT WINDOWS NT CURRENT VERSION SOFTWARE PROTECTION PLATFORM.3- Click on SOFTWARE PROTECTION PLATFORM and on the right of registry editor u will see the file ” SkipRearm”.

Right-click on SkipRearm, then modify the skiprearm value from 0 to 1.4- Now run command prompt as administrator and type slmgr -rearm.your job done. Nice stuff I have found here, But I saw that Changing product keys are not so difficult.

After some days ago, I need to install latest Operating system windows 8.1 pro at my notebook, So I install it with my DVD suit, But for getting its activation, I saw my product key was lost.I searched at yours as well as many other sites to buy a new one, but its all were free & blocked from Microsoft. Then One of my close friend told me about. From Where I bought a cheap one, Which is working well now. The last time i had a friend helped me with a permanent genuine windows, only if i don’t install certain updates from windows. It used a program downloaded from a link on the web.Then everything worked out great & there hadn’t been any problem ever since. But then one day, i accidentally installed an update & it ruined everything.

Now the screen goes back black with a windows not genuine message popping up every time i log into my computer. And for some reason i never noted the method. Did anyone ever passed by this kind of method before? I’ve not been in contact with him for quite a time, so i can’t ask anything from him. I have also used up all my three rearms & now I don’t really know what to do with my computer. If any of you ever came by anything similar. Please let me know.Albert.
