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
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
net.exe stop superfetch (hit enter and see if your disk usage goes down)
Step 4: Fixed!
