I have the exact same problem and feelings as Emily. Haven't been able to do any work for the last two days. My suspects are also One drive and service host.

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.

2015-09-09T03:48:15+00:00 I use Firefox and don't have Skype running. I stopped Background Intelligent Transfer Service and Superfetch as suggested, so now my disk use is down from 100% to 85% as I write.
The hog when I start up is OneDrive (which has had numerous problems since I upgraded to Windows 10) then it's this retinue of "Service Host: Local System" with all sorts of services that I doubt I need on a laptop.
I've turned off everything extraneous, including the P2P updates, and still have the problem. My fan is constantly running, even when HDD use is finally down 5%. This issue is SO frustrating and has umpteen solutions on the internet (including here) that I'm getting ready to revert back to Windows 7. It's a workhorse that works.
Appreciate any workable solutions. Please fix this Microsoft!

2015-08-30T20:07:25+00:00 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.

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!
