Resolution

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To resolve this issue, make sure that Remote Registry Service is running. Then, determine whether the issue is resolved. If the issue is resolved, do not perform the following procedure.

If the issue is not resolved, restore the default permissions to the
winreg

  1. Click Start, click Run, type regedit, and then click OK.
  2. Locate and then click the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurePipeServers\winreg
  3. Right-click the winreg subkey, and then click Permissions.
  4. Click Advanced. Then, add the following accounts and the corresponding permissions to the Permission entries list.
