Have A Look What Microsoft Says About This Problem :-

This can be caused by either of the following:

1. 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).

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

Because the Licensing service uses Plug and Play to obtain hardware ID information and binds the license to the computer, this 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 the appropriate rights to access the Plug and Play service. The Licensing service runs under the Network Service account.

2. Missing registry keys. One of more of these registry keys may be missing:

HKLM\software\Microsoft\Windows NT\CurrentVersion\Profilelist
