Perflib 1008 Error SBS 2003 R2

I am continuously getting the below perflib errors. I want to understand how to fix this issue and still use the performance monitoring functions, so if anyone can give me some suggestions for it then it will be most appreciated. Check the below messages that I am getting in the event log:

Even I was getting similar things but it shows me this message " The Open Procedure for service "ASP.NET" in DLL "C:\WINNT\Microsoft.NET\Framework\v2.0.50727\aspnet_perf.dll" failed. Performance data for this service will not be available. Status code returned is data DWORD 0". It seems to me that it started right after installing KB931768 and KB935966.

The problem occurs because the system removes the Pschdprf.dll file but does not remove the following registry values when the QoS Packet Scheduler is removed:

• HKEY_LOCAL_MACHINESystem\CurrentControlSet\Services\Psched\Performance\Libray
• HKEY_LOCAL_MACHINESystem\CurrentControlSet\Services\Psched\Performance\Open
• HKEY_LOCAL_MACHINESystem\CurrentControlSet\Services\Psched\Performance\Open HKEY_LOCAL_MACHINESystem\CurrentControlSet\Services\Psched\Performance\Collection
