How to activate windows after expiration

To activate your expired windows,just follow my little explanation below!
Click on START >> RUN >> and then type 'regedit'.
Now click on HKEY_LOCAL_MACHINE >> SOFTWARE >> MICROSOFT >> WINDOWS INT
Now you will see WPAEvent,all you need to do is just to locate OOBETimer,double click on it for it to open.
You will see a code,delete it and let's proceed...
In the position in which you deleted the old code,type and insert the following code:
FF D5 71 D6 8D 6F D5 33 93 FD
Note:You must not copy paste the code above because,if you do,it may not work so type it as shown above.
Next is to click on OK.
Right click on WPAEvents and then permissions and then select system and then DENY of FULL CONTROL and finally,click on OK.
Now click on OK dialog box until you are finished with it.
Next step is to close everything cos you are done.
CHECK IF IT WORKED
Now click on START >> ALL PROGRAMS >> ACTIVATE WINDOWS.
You will find out that the message that comes up will no longer be that windows is expired but windows already updated.
