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.

    I solved the problem by resetting the Windows Update catalog, but what causes Windows to screw itself up like that?

    @tommy2k7 & anyone else with a similar problem: To avoid confusion & duplication of effort, please begin your own, new thread in the appropriate forum. State your current IE version (e.g., IE8; IE9; IE10; IE11; IE11 Release Preview for Win7) and full Windows version (e.g., WinXP SP3; WinXP 64-bit SP2; Vista 32-bit SP1; Vista 64-bit SP2; Win7 32-bit; Win7 64-bit SP1; Win8 32-bit; Win8.1 64-bit; Win RT 8; Win RT 8.1) in your first post. Thank you.

    If you originally upgraded to Win8 (not Win8.1), please state that and your previous Windows version (e.g., Win7 64-bit SP1; Win8 32-bit Release Preview) in your first post, too. Thank you.

    Thank you for suggesting Method 1 Shinmila H! That solved the Trusted Installer taking up system resources however as soon as I did that, the System process (NT Kernel & System) process began taking up what was previously taken up by the Trusted Installer! Any suggestions?
