Windows 7 not genuine Error (Screen Turning Black)

Windows 7 may sometimes been detected as illegal, not genuine,or Pirated despite the operating system has been genuinely bought from market. Then it shows a message immediately after log on, the following Windows Activation window will be displayed:

Windows is not genuine Your computer might not be running a counterfeit copy of Windows. 0×80070005 not-genuine

Moreover, the computer desktop background is turned to black, after some time of logging in and the following error message is shown on the bottom right corner of the screen:

This copy of Windows is not genuine activation message

When you try to view the system information in System Properties (Control Panel -> System and Security -> System), the following error message can be seen:

You must activate today. Activate Windows now

Using slmgr.vbs /dlv or slmgr.vbs /dli in an elevated command prompt with administrator privileges to view the licensing status will return the following message instead:

Error: 0×80070005 Access denied: the requested action requires elevated privileges

Normally, the suddenly or random deactivation of an activated Windows 7 on genuine platform can be resolved by simply restarting the computer, so thatWindows 7 can re-access the activation status to return the computer to activated status. However, in some cases, where modification has been done to HKU\S-1-5-20 registry key causing the Network Service account to lose and missing full control and read permissions over the registry key, the losing of activated status may happen on Windows 7 too.

Microsoft explains in KB2008385 that the possible cause for the Windows 7 turned pirated error is likely the result of applying a Plug and Play Group Policy object (GPO):

Computer Configuration -> Policies -> Windows Settings -> Security Settings -> System Services -> Plug and Play (Startup Mode: Automatic)

The Windows 7 Licensing service uses Plug and Play to obtain hardware ID information and binds the license to the computer, thus change to the setting can result in an activated system appearing to be out of tolerance. The default permissions of the Plug and Play policy do not grant the Licensing service, which runs under the Network Service account, the appropriate rights to access the Plug and Play service. To fix and resolve the Windows 7 activation lost issue, and make the Windows 7 activated and genuine again, just follow one of the two Methods stated Below:

Method I: Disable the Plug and Play Policy

  1. Determine the source of the policy. To do this, follow these steps:
  2. 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.

run rsop service

  1. Visit the following location:

Computer Configuration -> Policies -> Windows Settings ->Security Settings -> System Services

policy set

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.
  1. 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).

Method II: Edit the permissions of the Group Policy

  1. Open the Group Policy that is identified in Method I, Step 1 above, and open the corresponding Group Policy setting.
  2. Click the Edit Security button, and then click the Advanced button.
  3. In the Advanced Security Settings for Plug and Play window click Addand then add the SERVICE account. Then, click OK.
  4. Select the following permissions in the Allow section and then click OK:Query template Query status Enumerate dependents Interrogate User-defined control Read permissions
  5. Run gpupdate /force after applying the permissions to the Group Policy setting.
  6. Verify that the appropriate permissions are applied with the following command:sc sdshow plugplay The following are the rights applied to the Plug and Play service in SDDL:D:(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;SY) (A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA) (A;;CCLCSWLOCRRC;;;IU) (A;;CCLCSWLOCRRC;;;SU) S:(AU;FA;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;WD)Note: (A;;CC LC SW LO CR RC ;;;SU is an Access Control Entry (ACE) that allows the following rights to “SU” (SDDL_SERVICE – Service logon user):A: Access Allowed CC: Create Child LC: List Children SW: Self Write LO: List Object CR: Control Access RC: Read Control SU: Service Logon User

If there are no GPO’s in place, then another activity may have changed the default registry permissions. To resolve this problem, perform the following steps:

  1. Click Start Menu, Then Run, then enter REGEDIT
  2. Right-click the registry key HKEY_USERS\S-1-5-20, and select Permissions… button.
  3. If the NETWORK SERVICE is not present, click Add… button.
  4. In Enter the object names to select type Network Service and then click Check Names and OK.
  5. Select the NETWORK SERVICE and Grant Full Control and Read permissions.
  6. Restart the computer.
  7. After the restart, the system may require activation. Complete the activation.
