TrustedInstaller using 1,000,000k memory under Task manager

I've just done a repair of my windows 64 os. I am now in the process of installing all the windows updates but have noticed that the TrustedInstaller.exe is using excessive amounts of memory, over 1,000,000k 

Surely this can't be normal?

Anyone offer any assistance?

Hello,

 

Welcome to Microsoft Community Forum.

 

Here's a little insight on TrustedInstaller service.

 

TrustedInstaller is used by a service called “Windows Module Installer” which is used to install Windows 7 system modules. The system modules include Windows Update and Automatic Updates which automatically scans your system to check for any new updates and hotfixes available. So when scheduled Windows Update is performing its update scan or check on your system, the TrustedInstaller.exe process increases the CPU usage.

 

The simplest resolution for the TrustedInstaller high CPU usage problem is to wait for a while for the TrustedInstaller.exe to complete its job. Once it finishes running the tasks, the CPU usage rate will return to normal.

 

However, if you want to stop TrustedInstaller.exe from taking up all your CPU resource, here’s a suggestion that may help.

 

Step 1: Disable Windows from automatically updating.

 

Here’s how: Turn automatic updating on or off

After disabling automatic updates, depending on your preference, you can change the way Windows notify you about updates.

 

Refer this article: Change how Windows installs or notifies you about updates

Step 2: Clear Problem History.

 

The following fix is intended for situations where trustedinstaller.exe causes problems due to the Problem Reports and Solutions history maintained in Windows 7.
