How to fix 100% disk usage in Windows 10
This is caused by a common combination of Skype as well Google Chrome. Similar issue with other programs could also cause 100% disk usage. To fix this do the following:
Google Chrome:
In Google Chrome, go to Settings > Show Advanced Settings ... > Privacy > Prefetch resources to load pages more quickly
and untick it. See Figure-1 below:
Figure-1
Skype:
Make sure you have exited Skype and it is not running in the taskbar (if it is running in the taskbar then quit it).
Open Windows Explorer and open the following folder:
"C:\Program Files (x86)\Skype\Phone"
Now right click "Skype.exe" file and then click "Properties" and open the "Security" tab.
Click the "Edit" button and then highlight "ALL APPLICATION PACKAGES" and place a tick in the "Write" box.
Click "Apply" and then "OK" and then "OK" again. See Figures-2 to Figure-6 below:
This is it, now run Skype and check the Disk Usage in Task Manager and it will no longer show you 100% disk usage anymore:-
I hope this helps people. I spent a long time in finding a solution to this problem.
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
The only thing that worked for me was to disable the Windows Defender. It will be enabled again after sometime, and then the disk usage goes up to 100%.
But there should be another solution, Windows Defender is a MS application and I should not be disabling it to bring down disk usage.
The laptop I am using is a MS Signature edition Dell i7347-10051sLV with 8GB RAM
In my case the the system is a 2010 ACER laptop with AMD dual core P320 processor. The SSD was installed a year ago and works fine with windows 7. I have the same SSD on my desktop that is running Windows 10 very nicely. I agree that when windows 10 works on my older and slower laptop that it is very nice compared to windows 7 in responsiveness.
"...the solution is disable one or more programs/ services and see if the disk usage drops."
Also, the Google Chrome at the top helped me with the problem.
My problem of 100% Disk usage ALWAYS goes away in about 2 minutes. I had no idea a person with a SSD drive was having a problem with 100% Disk usage that never goes away. That is not the problem I am having.
Are these old laptops we are talking about that have new SSD drives installed? I did have to take Windows 10 64 bit off of my old AMD Duo Core X64 laptop for heating up.
Right now my HP Windows 10 64 bit AMD Quad Core A10 is reading 4% CPU, 26% Memory, 0% Disk, 0% Network in the Task Manager.
Its not working, I don't have skype and chrome install but system hang with 100% disk activity
What solution are you referring to?
There is no single solution. It has different causes. Like i already explained i have done several things. Because the 100% came baxk several times
