100% usage on disk

Just wondering- how many disks do you have in your PC?
If you look at task manager, Performance, which disks are showing significant activity?

I have one disk and these are the names of the processes


I can get another keyboard and do a clean boot.
Once I do the clean boot I take a screenshot of my task manager or processexplorer?

Ok, it would be good to find a situation when you do not have this problem.
Currently I would only guess that to be in Safe Mode. Try Safe Mode rather than a clean boot- it's also easer to set up, and more basic.

Now, the names of those processes need research. A couple of them I've never seen before-- if you can find out anything about them- esp. the 4th and 5th - that would be helpful. The first is related to reports of various issues of resource use.

There are quite a few threads about Service Host: Local System on this forum, so you could search it and see if anything helps.

Please also try the suggestion first in my previous post.

Here's another (from this forum):


Others suggest disabling superfetch.

However, I have the uneasy feeling these are fudges and don't address the real issue.

What is your build number? (Windows key + R, winver)?

I've finally noticed this in my own task manager (scroll down towards the bottom)


I can only imagine this is something introduced more recently- that MS has given different instances of svchost different names, and expanded them like this.

So there's a simpler way to monitor these than Process Explorer.

Sorry for the late response. This is my build number and will do the safe boot later on today
