To make Windows 7 activated and genuine again, just follow one of the two Methods stated Below:


Method I: Disable the Plug and Play Policy

On the client computer experiencing the activation error, run the Resultant Set of Policy wizard by clicking Start -> Run (or press Win+R keys), and entering rsop.msc as the command.   

3. Visit the following location:
Computer Configuration -> Policies -> Windows Settings ->Security Settings -> System Services
          

 

If the Plug and Play service is configured through a Group Policy setting, you see it here with settings other than Not Defined. Additionally, you can see which Group Policy is applying this setting.

4. Disable the Group Policy settings and force the Group Policy to be reapplied.

• Edit the Group Policy that is identified in Step 1 and change the setting to “Not Defined.” Or, follow the section below to add the required permissions for the Network Service account.
• Force the Group Policy setting to reapply: gpupdate /force (a restart of the client is sometimes required).
