Service TrustedInstaller.EXE permanently active taking up to 50% CPU resources

On my machine (Windows 7, 64 Bit) the TrustedInstaller.EXE is permanently active. The amount of used CPU changes permanently. 2 seconds 0 % then up to 50% (I have a dual core) for a second then down to 0.

Rebooting the machine did not help. Also a complete Virus scan was negative.

I have monitored the process with the Process Explorer tool. I can see that the process always access the same Registry key when it gets active. The key is

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\PackageDetect\Microsoft-Windows-IIS-WebServer-AddOn-2-Package~31bf3856ad364e35~amd64~~0.0.0.

Hi Robear,

in the meantime I have found the process that was responsible for the trustedinstaller activities. It was the xenservice.exe that was installed together with the Citrix XenCenter on my machine. I have killed this process and suddenly the trustedinstaller.exe stopped its activities. So the problem is solved now because the XenCenter can work without this process and I will remove it from the auto

Thanks for your help.
