Microsoft is fully aware of this issue and provided following explanation for the issue,
There is a lack of permissions in the registry key HKU\S-1-5-20. The Network Service account must have full control and read permissions over that registry key.
This situation may be the result of applying a Plug and Play Group Policy object (GPO).
To resolve this issue, you can either disable the policy setting (Method A), or edit the permissions to provide the Licensing Service the required permissions (Method B).
Method A: Disable the Plug and Play Policy
1. Determine the source of the policy . To do this, follow these steps:
a. On the client experiencing the Activation error, run the Resultant Set of Policy wizard by clicking Start, Run and entering rsop.msc as the command.
b. 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.
2. Disable the Group Policy settings and force the Group Policy to be reapplied.
a. 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.
b. Force the Group Policy setting to reapply: gpupdate /force (a restart of the client is sometimes required)
Method B: Edit the permissions of the Group Policy:
1. Open the Group Policy that is identified in Method A, 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 Add and 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
Note: The Previous rights are the minimum required permissions.
5. Run gpupdate /force after you apply the previous permissions to the Group Policy setting.
6. Verify that the appropriate permissions are applied with the following command:
sc sdshow plugplay
