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

    BAHhahaha my wife's W7 laptop just started to do this with the installer and svhost. All she does is check her email with it.

    Can't even do that now with 100% CPU usage going on for 12 hrs.

    Time to teach her Linux Mint.

    I am considering buying a full retail Win 7 Pro, wiping the drive and doing a clean install. [SOURCE]

    Good luck with that!

    Yes, only one computer involved - a Sony VAIO laptop. 

    I replied to your other question post like this.

    Heading towards a clean install next week.

    I upgraded from Win 7 Home to Win 7 Pro...

    Is it the same computer (not the same problem) in this previous thread of yours and/or your "Me, too!" post in this recent thread?
