Service TrustedInstaller.EXE permanently active taking up to 50% CPU resources

Anonymous

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 M.Herbst,

Follow this steps, please:
1. Open Task Manager (you can click on Start and search "Taskmgr.exe" , without the quotes, and press Enter )
2. Search for the program.
3. Right click on the program and select Jump to details.
4. Then right click the marked process.
5. You will see different options:
a) Set priority: Click the option, and select minimal. Proceed to b) .

b) Set affinity: Click the option, uncheck "all processors" and check CPU 0.

After doing this, if it's working, you are all set. If not please contact me at ******@yahoo.com.

Shinmila H,

I got to say that are just one big idiot. The advice that you give is bull, that is unless a person never wants to use their computer.

For all those out there reading this, know that on a brand new computer with all Service Packs, Updates, and Hot Fixes. The 36 Computers of all classes and grades, ALL HAD THIS ISSUE! 31 out of them would never give up the processor for more than 1 to 2 hours in a 96 hour run. We did this for three runs each.

My earlier post, is the only way that we were able to solve the problem (post on disabling auto update, and renaming file). Because of this issue and others, all my clients are finally back on Vista or Linux.

Take into mind that this was the very last resort. It is not any fun migrating 30,000+ clients down stream when they were sold a bill of goods that is nothing like they were told.

Bottom line is this people. THERE IS NO REAL OR EASY SOLUTION FOR THIS PROBLEM!!! If you listen to the people at Microsoft you will be pulling your hair out!

I had this problem for the very first time on my Win-7 64-bit. After running the Fix-it, my problem stopped w/o even having to reboot. Amazing. Big fan of Fix-it. I have used many when I first started using this computer and they helped increase my "User-Index" score and performance. Thanks for link.
