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

    Hi I found that on computer startup with no internet connection, the trustedinstaller.exe was taking ~50% or more of CPU resources. After manually connecting to the Internet, the CPU usage reduced & disappeared. Using VISTA.

    Well that makes sense. If you've read the thread, you can see that what it's doing is repeatedly checking for updates, ignoring the lack of connection. If you've already turned automatic updates off, I suggest you go the msconfig route and turn the process off.

    It's 2013...

    Same here, clean and fresh Win7 installation, took me 5 hours(!) including Servicepack1 and updates. Runs permanently after booting up, using >50% CPU, for 10 or more minutes... Why trust that installer, if I don't even know what is going on?? What does it install? There are not even programs installed on this system yet.

    That computer was even sold with Win7 but is absolutly too slow to run it. 2GB memory.

    Which computer do I need to run Windows in 2013? Windows didn't get any faster in the last 20 years...

    Love this response! Its valid and concerning! I'm here two years after this post with exactly the same issue! Not only is it using 50% to 60% of my CPU, its wacking the **** out of my hard drive! I have had enough time to search, find this thread, read it, and write this and its settled at like 32% and is whilring the HD so much that I can't do much else. Specs Dual Core, E2200 2.20 Ghz 3 GB Vista 64bit I know its Vista, its my wife's PC.
