Tips & Tricks: Windows 7 Build 7601 not genuine after installing Service Pack 1 FIX

--------------------------------------------------------------------------

OK.. I've figured it out how to restore my previous Genuine licensed, after i got this message saying that my windows is not genuine. In my case i already applied RemoveWat 2.2.6 before i installed SP1,but then after i installed SP1 on my PC it was a mess.

After i installed SP1

After steps applied - or in your case the "Windows Activation" INFORMATION may not appear,but that's fine.

IMPORTANT: For those who haven't install SP1 patch and planning to install it. Manually download SP1[link below]. First make sure you implement this two steps [1 and 7] and do this method here.
Install SP1 and do the entire process[1-7].

If SP1 installed already,apply the whole steps.

The validation and updates will still be available after you apply the steps.

GOOD LUCK!

1. First we need to Uninstall Windows Activation Technologies (WAT KB971033) it has to be removed before we proceed.

Go to Control Panel > Programs and Features and Click "View Installed Updates" on the upper left corner. Then right click to “Uninstall” the patch then press "Yes" as shown below.

Or Do this Manually

Go to "*\system32" folder and delete the folder 'Wat'(download TakeOwnership file here merge it to your registry).

2. Run RemoveWat 2.2.6 [Run as Administrator]Click "RemoveWat" button, then restart...[Download link at end]. If 'RemoveWat' button is not available,proceed to 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.

[this is optional if you still have trial appearing on system properties or the not genuine message]
