Windows 7 Build 7601 not genuine after installing Service Pack 1 FIX(Updated))

Well I was facing problems on my other computer where the windows was still not activated. My work was compromised due to it so Today i Decided to write a post on how to activate it to let go of that annoying message “windows is not activated and blah blah blah”
So here are the foolproof stepsThere are many ways on the net to activate windows 7 ultimate but only a few work out– this is one of the working one’s as i have tested it myself
1.If you know your windows is not an bought one then i recommend you to use this software called windows loader. to use it just run it– it takes some time to run on slow computers as it analyses your computer and accordingly loads the correct serial in it. This will do your work and you dont need to go more deep into the other steps.
2.For those who already have that annoying message called windows is not activated in your black desktop these are the steps for you
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 I finished my work

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

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.

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.

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