I seem to be seeing this issue more and more. I have 2 identical HP PCs. Both are running Windows 10.

They have both started to run very slowly. I have notice that they are running at 100% active time.

How do I pinpoint what is causing this issue. Are there any tools that would help me troubleshoot this?

Hi,

You can use the built in Resource monitor to see what is causing the high disk activity.

You should leave the Resource Monitor running for an hour or two. You can minimize it to the taskbar. The main disk processes tend to stay near the top while busy. I use resource monitor.

My laptop started to exhibit this behaviour at Startup, with the system being slow and disk 100% active for approx 10 Minutes after startup under Windows 8, it seemed to be down to things like the virus checker etc.

I resolved this by replacing my HDD with a SSD - Problem solved
