What does 100% disk usage mean in task manager?

Solution 1

Open a cmd.exe as a admin (windows key+x+a)

Now you stop various suspected services and watch how the system responds in resouce

monitor. I would recommend you to stop Superfetch and Windows Search service.

For Superfetch: Open cmd and type - net.exe stop superfetch (hit enter and see if your disk

usage goes down after a min or two) or you can stop it from Services under Computer

Management.

For Windows Search: , net stop WSearch or Stop it from services under Computer

Management.

Solution 2

Go to charms bar and press search, then type view local services.

Once here, stop and disable BITS (Background Intelligent Transfer Service).

You can also set Windows Update checks to manual.

One more thing that conclusively worked for me was the combination of Disabling

Hibernation and Turning Off the Pagefile. Try this and I guarantee that this will work if you're

having the pagefile disk usage problem.
