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.

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.
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...

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.
Hi y'all,
One of the oldest problems in Windows appears the be the load-up sequence. Things are better now but it still rears its ugly head......hence, I assume, some kind of Installer. There is no cure for the requirement to install things properly - you must wait out TrustedInstaller. If it keeps on hammereing away then it obviously has problems. Taking out TrustedInstaller is NOT progress, so try this:
Go into msconfig, hide Microsoft services, then turn off everything in the tabs BOOT then STARTUP.
Reboot and then re-instate in groups of no more that 4 at a time.
This, I suggest, allows TrustedInstalled to re-order things properly.
Obviously; if one app is found which causes problems it can be dealt with. I did this to my WVista PC which is 5 years clogged and it was resored to instantly restored to health and vigour.
Hope this helps!
