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.

Martin

    wow, I cannot believe that so many others have had this exact problem before. 

    Sounds like one amazing CF to sort out and get things right again.   Makes me kind of angry that all the years I have had to deal with this is inherent in the system and I have to jump though massive hoops to stop this stoopid updating from taking over my machine.   I can see it sucking gobs of data through the network and I will try waiting it out, but MAN it is a mess.  It stopped some months ago and since the last update windows did, it has totally destroyed my CPU's processing power (videos skip, I can't type without it interfering). 

    Other folks have thought I was insane or had installed something screwy or had malware.  Glad to know it is a real problem inherent in the system and I have some suggestions on how to fix it from the community here.  Thanks to those of you with expert knowledge that are trying to help us NOT so savvy users find a solution.
