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.

Yes, many sources says it is not a bug. But booting up the computer I need to wait for more than 5 minutes for 100% disk activity to stop is just ridiculous. This is not limited to after boot up, it can pop up randomly and at the most inopportune time.

Same thing happened to me , it got to the stage i was reformatting the laptop. In the end the only thing that worked for me was to disable pagefile / virual memory.
I have read the comments blaming everything from skype to OneDrive to prefetch.
I am saying there are two conditions that create the 100% disk use - the one is when the computer is really busy and the 100% condition allows each task to get a turn at the disk. This is normal and not the bug.
The incorrect 100% Disk appears and kills the normal operation when the Disk usage gets to zero. My fix is to run a program that never allows that condition to be reached.
I have a blog that explains this in detail Click here: wordpress article to read. There may be other ways for it to appear and may need a different work around. It would be useful to hear if your problem is different.
Reversing your solution, for me on Windows 10, solved my laptop problem--I had been running BITS on 'manual', but when I changed the setting to 'automatic' it immediately dropped from 100% down to less than 10%.
Please do not quote the whole post, especially if you have nothing to add to it.
I add a SOLUTION: NOT PERMANANT but can be kept on being done.
Type on search "view local services" select "Background Intelligent Transfer Service" stop it and go to properties and select disabled it will hold more a less a day it will take 2 or 3 minutes to stop disk at 100% usage.
Joni give us some solutions!
Disabling an integral system service is ill advised. You need to figure out the real cause of the high disk usage and then resolve that problem. I will recommend you use msconfig to run in safe boot mode with networking and also disable all non microsoft services in the services tab and then see if it resolves the issue, if it does then start enabling one service at a time to find out which causes the problem to appear again.
Hope this helps.
This is an important idea if your system goes down to almost 0% after only 5 minutes. There are programs like, "Antimalware Service Executable:"
"In the Task Manager (pictures below are from Windows 8.x but the process is identical in 7 and older), if you right click AntiMalware Service Executable, you can open the file location. The MsMpEng.exe is the file used by Windows Defender/Security Essentials to scan your PC files."
That is the highest percentage showing in the Task Manager at my Start-up, and I have determined that it is something that I want to run at the start.
It is wise to be careful.
