I initially ignored this error and trying to see if anything was wrong but after looking at the details tab I realized that the whenever I started the Office Search Service, the content access account was trying to access the VSS registry key and it was failing due to lack permissions. So here is the fix, just type in regedit.exe in run and navigate the VSS registry key

HKLM\SYSTEM\CurrentControlSet\Services\VSS\Diag

Right click on Diag, go to permissions and give the service account listed under details tab in the error with full control permissions.

This should fix the error, you can check this by restarting the office search service by using NET STOP OSEARCH and NET START OSEARCH

Shoot me an email if anybody have any questions!
