Disk Activity at 100% with low Read/Write

Windows Version: 20H2 OS Build 19042.804


Hey Everyone,

I recently updated from W7 to W10 and now my PC has been running very slow.

My disk usage is typically no higher than 40% however I am pretty much always at 100% active.

I have tried multiple things online; however I cannot figure out what is the cause.

I tried

1. Disabling search/superfetch
2. Resetting page file
3. Disk Check
4. Disable Windows Update

Any Help Is Appreciated! Thanks!

I typically do not have steam open, but I realize it was open in that screen shot so i'll give it a shot thanks!

Unfortunately this does not seem to make much difference.

Hi lsutigers, welcome to Ten Forums.

Has this 100% disk activity been happening ever since the upgrade to Windows 10?
Was the upgrade performed while online using Windows Update?

Why not start with a boot to Safe Mode and see how the disk activity performs.

Boot into Safe Mode on Windows 10

If the disk activity looks better in Safe Mode, follow that with a clean boot.

That didn't really seem to do much....

I ran a process explorer and got the following.

Sorted By File Events

Sorted By Registry Events


Is this out of the ordinary? Those numbers seem high for the system not seeming to be doing much. Sub 5% CPU and Low RAM use.

Sometimes it seems to calm down and be fine but as soon as I do anything it peaks again and lags again.
