Perflib (WmiApRpl and BITS) on Server2012 and SharePoint 2013

I have been searching for a way to get rid of some performance counter errors (WmiApRpl and BITS) on my SharePoint 2013 installation for a while but couldn’t find the answer. Today I decided to have a look with Process Monitor and finally found a solution.

The w3wp process tries to access to registry keys but does not have the permissions.

After granting the WSS_WPG group full control(you probable can get away with a little less) to the following registry keys, the errors went away.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BITS\Performance
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WmiApRpl\Performance
