Resolved: How to Make Windows 10/11 Use 100% of the Disk

It is time to take action now that you have located the program in Task Manager that is wasting a lot of disk space. The greatest fixes for 100% disk consumption in Windows 10 and Windows 11 have been prepared by us. Depending on what caused the issue, there are several procedures to take in order to solve it, however here are some typical fixes:

1. Turn off MSI Mode for the AHCI Driver by Default

To address the 100% disk usage issue in Windows 10/11, you should first disable MSI mode for the AHCI driver that is default. You will lessen the quantity of queries that are sent to the disk by doing this, which should assist in lowering CPU and disk utilization.

Warning: Before attempting the steps outlined below which involve making changes to Windows Registry, we strongly urge you to create a restore point in Windows.

To turn off your AHCI driver’s MSI mode:

1. Use the keyboard shortcuts Windows + R to launch the Run application. Enter devmgmt.msc here, then click OK to launch Device Manager.

Task Manager

2. To view all of your linked drivers, click the arrow symbol next to the IDE ATA/ATAPI controllers area. Using the context menu, right-click on the Standard SATA AHCI Controller and choose Properties.

Task Manager

3. First, use the top menu bar to navigate to the Driver tab. After that, select the Driver Details button and confirm that the storahci.sys driver is there in your list of driver files.

Task Manager

4. Your high disk consumption may be caused by the presence of the storahci.sys file. To close the interface and navigate to the Details tab, click the OK button.

5. From the Property drop-down menu, choose Device instance path. When the value appears, right-click on it and choose Copy from the context menu. It is advised that you copy and paste the value into a blank Notepad document.

Task Manager

6. Next, type regedit into the input area to launch the Registry Editor by hitting the Windows + R keys on your computer. Click OK to launch the application.

Task Manager

7. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI\AHCI Controller Value\Device Parameters\Interrupt Management\MessageSignaledInterruptProperties is the registry key you navigate to.

8. To determine which folder is accurate, use the value you wrote down. The primary folder that you must access in the Registry Editor is indicated by the first portion of the value, and the subfolder that you must choose is indicated by the second part.

Task Manager

9. Proceed to Device Parameters > Interrupt Management > MessageSignaledInterruptProperties. From the right-side pane, double-click the MSISupported key.

Task Manager

10. After setting the Value data to 0, click OK. To complete the modifications, exit Registry Editor and restart your computer.

2.  Turn off the Superfetch (SysMain) Service.

After turning off MSI mode for the default AHCI driver, if the excessive disk utilization persists, you may want to try turning off the SysMain (Superfetch) service. This is a Windows service that speeds up application launches by preloading them into memory.

But because the service pulls data from your drive continuously, it can also result in a hard disk use issue, which causes your hard disk to spike. To turn it off:

1. Using the keyboard, press the Windows + R keys. The Run utility will launch as a result.

2. After entering services.msc, press the OK button. The Services window will open as a result, and it may take some time to fully load.

3. After you reach the SysMain service, scroll down. From the context menu, select Properties after performing a right-click on it.

Task Manager

4. Continue using the General tab. If the service is currently running, make sure the Startup type is set to Disabled and then click the Stop button beneath the Service status. By doing this, you can prevent the service from starting on your computer’s startup automatically.

Task Manager

5. To close the window, click Apply and then OK. Check to see whether, after doing these steps, you are still seeing 100% disk use.

3.  Turn off the telemetry service and connected user experiences.

A Windows feature that gathers information about user activities on your computer is called the Connected User Experiences and Telemetry service. If you are having problems with 100% disk usage, you should disable this as it can result in high disk usage.

3. To close the window, click Apply and then OK.

Your device should now have the Connected User Experiences and Telemetry service disabled. After completing these procedures, check to see if the Task Manager still displays 100% disk utilization.

4. Turn off Windows Search Service.

The Windows Search service is another program that may result in excessive disk consumption. Although this indexing tool speeds up file searches on your computer, it has been known to occupy large amounts of disk space. Disabling this service will cut down on the amount of reads and writes to the disk if you do not require it.

1. To access the Services applet, follow the instructions in the second solution. Locate “Windows Search” here, then select its Properties.

2. Continue using the General tab. If the service is currently running, make sure the Startup type is set to Disabled and then click the Stop button beneath the Service status.
