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

    Arod0302, pls try to start chkdsk like this:

    • Click start and enter cmd in the bottom left search box
    • Right-click the cmd-application that is found, and select Run as administrator
    • At the command prompt enter exactly and including space

    chkdsk c: /r

    • You will then be asked if you want to check the disk at the next boot. Answer yes, then close and reboot.

    The disk control may take several hours at boot-up on Windows 7 and older.

    You may also want to check your disks smart values. There are several applications that can help you with this. Unfortunately lots of it comes with third party malware so be careful. See neiljn's post below about CrystalDiskInfo, which I also recommend

    I have solved the problem of high cpu useage by trustedinstaller on one old Vista computer.

    All other suggestions I see in different fourms involve turning off Windows Update or other bad solutions.

    Symptoms

    • Trusted Installer uses high cpu. On normal computers high cpu usage will last for a few minutes and then go down to around 0%. On this computer cpu usage was stuck at 49% (which means 98% of one of the two cores).

    Before you begin:

    Please make sure that you have no interferring programs (registry cleaners, malware, etc)

    Please make sure to run chkdsk /r so that your disk is error free.

    Solution

    1. Click Start and enter services.msc in the search box at the bottom to start the Service Explorer.
    2. In Service Explorer, find Windows Modules Installer (Tusted Installer = Windows Modules Installer). Stop it. Then Disable it.
    3. Restart you computer and go back to Service Explorer.
    4. In Service Explorer, find Windows Update and stop it
    5. Open a File Explorer window and go to C:\Windows\SoftwareDistribution\Download. Delete everything inside the Download folder
    6. In Service Explorer start the Windows Update service again
    7. In Service Explorer, find Windows Modules Installer. Make sure it's set to startup Automatically.
    8. Wait an hour or so. Trusted Installer may want to try to finish what it was doing when it was stuck, but now it may actually finish it.
    9. Start Windows Update again and ask it to do a new search for updates.

    Hope this works for you too!
