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.

[1] I have also remove the anti-virus tool but also without any effect.
[2] Some days ago I upgraded from KIS 2010 [to KIS 2011] and I am not sure whether the problem started after this upgrade.
A1. I don't understand what you meant here. Please elaborate.
A2. Had your KIS 2010 subscription already expired by the time you purchased & installed/upgraded to KIS 2011?

A1: I thought that maybe KIS caused this problem. I was not sure whether the problem started before the upgrade to KIS 2011 or after the upgrade. Therefore I removed it totally but the problem was not solved.
A2. No it was active,
Can you successfully reinstall KIS 2011?
After doing so, you can manually & repeatedly update KIS until you get a "no more updates" prompt?

Reinstall was successful. Update was running automatically. Then I started a manual update. KIS was searching for Updates and then finished with "no more updates". Seems to be OK.
