Trusted Installer gobbling up my processor usage

spotify95 said:

Btw, when you say the fix could be "tricky", what do you mean - could it be as bad as having to back up everything, and reinstall Windows? As I don't have any windows discs whatsoever.

I meant that if the problem was with Windows Updates then it can be hard to fix but mot impossible.

Also, out of interest, is there a program that is like the Windows Task Manager, that can sense a certain task appearing and killing the task automatically on sight?

Yes there are programs that can kill a process if found running but that's not a fix. In any case trustedinstaller.exe does need to run as part of Windows Updates.

Is there any chance of posting a screenshot of task manager when the problem happens with processes sorted by memory usage - highest at the top?

[EDIT]

It might also be worth trying to disable windows update drivers search.

Start> Right click Computer

Choose "Properties"

On the left side choose "Advanced System Settings"

On the Hardware tab choose "Device Installation Settings"

Set it like this:

Also if you are missing this update download and install it. Stop Windows Update Service before installing.

Microsoft Security Bulletin Summary for June 14th 2016

Get the update - Security Update for Windows 7 for x64-based Systems (KB3161664)

from the following link using Internet Explorer:

https://catalog.update.microsoft.com...px?q=KB3161664

Save the download to your desktop.

Then Start> Run

type services.msc

Scroll down to windows update service and stop it.

Install the update by double clicking the file you downloaded. Once installed - reboot and wait a few minutes before running an windows update check.

See if that works any better.

If not:

Open an Elevated Command Prompt. When the prompt appears type Powershell then press Enter

Wait for the PS prompt to appear then copy and paste the following. In order to copy and paste you need to enable Quick Edit Mode. If you can't copy and paste you'll just have to type exactly what is shown in the box below.

Code:

get-hotfix -id KB2990214,KB305026,KB3065987,KB3075851,KB3083324,KB3083710,KB3102810,KB3112343,KB3135445,KB3138612

That should return a list of installed and previously installed Windows Update Clients. It might take a minute or two before results are displayed. Post a screenshot of the results.

Hi,

Updating this thread as I still haven't managed to completely cure the issue.

TrustedInstaller no longer gobbles up my CPU usage; however, a process called "svchost.exe" does the same thing as what TrustedInstaller used to do; i.e. gobble up 25% of my CPU power whilst doing nothing to my computer.

Disabling the Windows Update process fixes it, which I have to do every day as Windows Update gets stuck on "checking for updates"; it doesn't actually do anything.

Also, this is now happening on both my Windows 7 PCs, not just the one that it used to affect...

Hi yep trusted installer will do that after installing updates

svchost well that one happens if the windows update search hangs
The post Callender points to should help,
This is a newer update client for June brds posted about yesterday that also might help
But yes you need to switch to Never check for updates and restart the machine before installing it
