After steps applied – or in your case the “Windows Activation” INFO may not appear,but that’s fine. like this

already,apply the whole steps.

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


  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 posted below.[If ‘RemoveWat’ button is not available,proceed step 3] (if the windows7 is cracked before you install the window just skip to next step)
  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 apearring on system properties or the not genuine message]
