How to Fix 100% Disk Usage for Windows 8.1

Like the title says, we're gonna try to fix the 100% disk usages problem in Windows 8.1.

I have looked at several different systems (Windows 7 and 8) that had the disk usage near 100%. The problem is that each one had a different solution so, it 's hard to say what the fix would be. But I can give you some ideas to help isolate the cause down.

The solution for the 100% disk usages we're gonna use works in Windows 7, 8, 8.1. I didn't test it on Windows XP, Windows Vista or Windows 10.

Step 1: Open the Task Manager

First we're gonna open the task manager and take a look at our disk usages. So as you can see it is now 100% and is slowing our computer down.

You can start task manager by right clicking on the Windows toolbar and selecting "start task manager". When task manager has oppend select the performance tab, open resource monitor, select disk tab

Step 2: Open Cmd.exe

So now that we know that our disk usages is too high we're gonna try to fix that. To fix the problem we're gonna use cmd to stop a Windows service that causes the 100% disk usages.

First open a cmd.exe as a administrator (windows key+x+a) or open it using the windows search function. Once you found it in your search results, right click on it and select "run as administrator"

Step 3: Execute the Cmd Commend

Now we have oppend our cmd.exe we can stop various suspected services and watch how the system responds in resouce monitor.

for example:
net.exe stop superfetch (hit enter and see if your disk usage goes down)

Step 4: Fixed!

So as you can see or disk usages is now 0%. Problem solved!
