Sandboxed Code Service is failing to start

I was working on a issue today where The processes associated with the service will appear to come up to the user but will disappear immediately. The SharePoint ULS logs show the following error:

'Process perf counters are disabled. Sandboxed code monitoring cannot continue.'

After alot of search i found that This issue occurs when the registry key 'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PerfProc\Performance\Disable Performance Counters' value is set to 1.

To fix this issue, you will have to modify the registry
