Task Manager might show 100% disk utilization on Windows 10 devices.

Your computer is hanging. Same old Windows, right? Except you’re using a brand new Windows 8.x or Windows 10 device, you’ve only had it a few days. So just what is going on?

Investigating, you discover that your system drive is running at 100%. Surely this can’t be right? Sadly, it is. The latest versions of Windows have a problem with the drives being over worked, which slows down the operating system. This issue affects both hard disk drives (HDDs) and solid state drives (SSDs).

Several fixes are available for this, depending upon what exactly is causing the problem, here we are going to cover some of main reason for it.

Solution 01

Open up a run dialog by holding down the Windows Key and pressing R. In the “Open” field, enter “services.msc”. Look for “Windows Search” and “Superfetch.”
Go to each of these entries. Right click on one and select “Properties.” In the dropdown box labeled “Startup type,” choose Disabled. After leaving the properties window, press “Stop” in the upper left corner. Do this for both.

or the CMD (Admin)


Solution 02

From the Windows Menu, go to Settings, then go to System and then go to Notifications and Actions. Turn off “Show Me Tips About Windows”. That’s it. It takes maybe a minute or two to lower the disk usage and I would recommend ending any process in task manager that’s making the disk usage go up in the meantime. Usage percentage should go down and stay around 1-2%.


Solution 03

Some users said after trying stopping and disabling WSearch, superfetch and BIT all worked temporarily.

Then real culprit seemed to be the pagefile settings.

imageGo to control panel/system and security/system/advanced system settings under performance click settings, advanced tab click change, set min to 1024 x your ram to convert to MB and set max to 2 x the min. click set, OK and apply.

Requires a restart. Stopped my 100% disk usage and windows now loads faster hope this helps.

if you have 4GB RAM, then the pagefile should be 1024 x 4 = 4096MB & Max to 4096 x 2 = 8192 MB or any higher value than.

Also remember, the same will be consumed from your Hard Disk Drive.
