Five ways to fix 100% disk usage on Windows 10
We have listed five different ways that can help you in resolving the 100 percent disk consumption problem on a Windows 10 computer.
Fix #1: Fixing the StorAHCI.sys Driver
Microsoft support claims that the Event ID 129 that indicates the disk manager resets results from various factors. The most common factor for this is that the models of AHCI PCIe (Advanced Host Controller Interface PCI-Express) result in such symptoms on a Windows 10 computer when they are run with the driver of StorAHCI.sys.
Owing to one of the firmware bugs, the SSD (Solid-State Drive) is unable to input or output when the mode of MSI (Message Signaled Interrupt) is enabled. This facilitates the storage stack of Windows to reboot the PC after attending the unresponsive write or read command for some time.
Therefore, to fix the 100% disk utilization issue on your Windows 10 PC, you must disable the MSI mode through the registry before identifying whether the inbox AHCI driver is running, which you can do as follows:
Press the ‘Windows’ and ‘R’ buttons simultaneously so that the ‘Run’ box crops up on your computer screen. On it, you need to enter “devmgmt.msc” in the space provided and then click on ‘Enter.’
Within ‘IDE ATA/ATAPI Controllers,’ you need to click your mouse’s right button on ‘Standard SATA AHCI Controller’ and click on its ‘Properties.’
Open the tab that says ‘Driver’ and click on the ‘Driver Details’ button on that tab. If you notice ‘storahci.sys’ written in the system 32 folder path, it means that the inbox driver is running.
To stop MSI, you need to close the ‘Details’ tab and click on the ‘Details’ tab next to the ‘Driver’ tab. Within this tab, you must choose ‘Device instance path’ from the menu of ‘Property.’ Note the path ‘Value,’ which begins with ‘PCIVEN.’
Now, you must type “regedit” in the ‘Run’ box and then hit ‘Enter’ on your keyboard. This will run the Registry Editor on your PC.
Go to ‘ HKEY_LOCAL_MACHINESystemCurrentControlSetEnumPCI<AHCI Controller>Device ParametersInterrupt ManagementMessageSignaledInterruptProperties.’ Here, the <AHCI Controller> indicates the ‘Value’ path you noticed above. The <Random Number> will vary for different machines.
Now, click on ‘MSISupported’ and enter 0 in its ‘Value data’ box. Click on ‘OK.’
After this, you need to restart your PC and check if this method works for you or not. If not, check out the second method for fixing the 100% disk utilization error.
Fix #2: Changing energy options

Open the ‘Power Options’ of your PC.
Go to ‘Advanced settings’ from ‘Change plan settings.’
Within this, you need to select ‘High performance’ from the list.
Ensure that all the power plan settings are put on default.
Arrow-right, click ‘OK’ and you’re done.
Fix #3: Changing settings of Skype and Google Chrome
Even the settings of both Google Chrome and Skype can lead to the problem of 100% disk usage in a Windows 10 computer. You can rectify these settings as follows:
Open the ‘Google Chrome’ browser on your PC. Click on the three-dot icon, displayed at the top right side of your computer screen. Within this, click on ‘Settings.’ Note that different Chrome versions might have slightly different wording.
