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

    Glad you got your up and running well. My wifes is now working as she would like it as well.

    My 4 year old Toshiba Sat200 is going through the same with updates so I stopped it.

    It now has Linux Mint on it and other than having to load the Epson printer driver with CMD it has everything I need.

    I took 15 minutes to load and another 10 to get the updates.

    Time to move on since I don't play games with any of my computers.

    Awesome,

    Method 1 did trick for me. I was fighting with this problem for months on multiple computers and always thought that Windows Updates are the cause. As soon as I cleared the history the trustedinstaller.exe process disappeared.

    Thank you

    Update

    A few days later the trustedinstaller.exe came back with high CPU usage. Not sure if it was coincidental, but I've noticed java updated on the taskbar notifying that java update is available. I ran java update and pretty much right after java installed, the trusted installer disappeared....Now lets just hope that it's gone for good.

    How did you find that it was XenCenter using TrustedInstaller.exe ?
