Windows 7 Build 7601 not genuine after installing Service Pack 1

OK I've figured it out how to restore my original license before, after I got a message saying that windows is not genuine. In my case I have applied RemoveWAT 2.2.6 before I installed SP1, but after I installed SP1 on my PC a mess.

1. First we need to Uninstall Windows Activation Technologies (WAT KB971033) it has to be removed before we proceed.
2. Run RemoveWat 2.2.6 [Run as Administrator]Click "RemoveWat" button, then restart.Download link posted below.[If 'RemoveWat' button is not available,proceed step 3]

3. After you reboot repeat step 1 to check whether the (KB971033) patch is properly removed. If patch appeared on the list proceed to step 1 except step 2[if not on the list proceed step 3a] and after you “Uninstall” Patch (KB971033) on the second time open “Task Manager” Click on the “Processes” Tab, find “dllhost.exe” then End this Process.

4. After reboot

Download my slmgr file,link posted below

For 32bit OS: paste it on "C:\Windows\System32" Folder

For 64bit OS: Paste it on "C:\Windows\SysWOW64" and "C:\Windows\System32" folder.

5. Click Start Button and type “cmd” then important to run “CMD” as administrator. On cmd type the following command “slmgr[space]-rearm” and a msgbox will appear says that you have to restart your pc press ok then restart.
6.After restart,run CMD as administrator type the following command "slmgr[space]-ato",press OK.[if error occur ignore it].
7. Click Start button type "Windows Update" and run,Click "Change Seetings" and set "Important Updates" to "Let me choose whether to download or Install them" press Ok,click "Check for Updates".If windows finds an important update,click on it to verify. If patch (KB971033) is on the list, right click then "Hide Update",else don't hide if its not (KB971033).
