Svchost.exe using up a lot of resources!

IanWF · 15 Jan 2016

This started happening about a week ago and I couldn't find any solution that solved my problem. I eventually did a complete system restore and it was back at factory everything, only to find that the problem didn't dissapear. Here is the process list from Process Explorer

And whats running it.

I really need to solve this problem, I not sure what to do, i've tried almost everything, Rkill, Tdskill, Running every malware and maliceous file scanner and nothing can find anything

Manually install KB3112343 (if not already installed).

See if that lowers the CPU and RAM usage.

Ok, trying it now.

Its been saying "searching for updates on this computer" for a while now.

Did that KB finally install?

It did cut it down but i still fill like its using too much, its still using 40% of memory, and it uses more cpu than it should too

It went up to 50% memory, and this is while nothing else is running

Try these steps: Windows Update - Reset

See if that lowers the RAM and CPU usage.

seems to have went down, but im not sure how much it actually should be using, its still using up memory, should it be completely gone?

The svchost process that oversees the Windows Update process also oversees several other things. It is going to show some RAM usage and that usage will vary from computer to computer because of some of the things that I mention below.

The RAM usage shown by Task Manager or Process Explorer is of limited value. Those tools are good when you need to monitor a process where RAM usage is climbing or has climbed to some large amount. ("Large" being rather subjective and will vary with the process. e.g. We would not expect the process named System to occupy several GBs of RAM.)

RAM "usage" is a problematic term. Processes "use" RAM and then release some of it. If no other process needs that released RAM, Windows Memory Management might leave it assigned to the process that released it. What counts is how much RAM a process has locked (not released).

RAMMap is a tool that lets you see a snapshot of how RAM is being used/locked/released per process. Resource Monitor shows a bar indicating how much RAM is in standby (released - but not yet reassigned) for the entire computer.

The svchost process that oversees the Windows Update process might have completed some tasks on your computer that it has not started on my computer. A precise comparison between two computers is not possible. Gross comparisons are fine and judging from your screenshot, none of the svchosts processes are using too much RAM (locked or released). They could each be using two or three times what your screenshot shows and still be okay.

Having said all of that - let me add this:
When troubleshooting, it is fine to look for extreme RAM usage; but, RAM is there to be used. There is not much point in seeing how much RAM one can not use. Posting screenshots and asking for gross comparisons is fine. You might eventually get a feel for what is normal for your computer.
