A computer should rarely ever run at 100% Disk Usage, especially a new computer.
Outside of malware and viruses on your machine, here are a 10 things you can look for:
1) Services – Windows Search has been known to sometimes cause problems while indexing your files.
You can manually stop this service just for your current session until the next boot by stopping the services in an elevated command prompt:
net.exe stop “windows search”
To permanently disable the service, press Windows + R, enter services.exe, and hit Enter.
To find the Windows Search, click the top row and begin typing Windows Search. Double click the row. Click the Stop button to stop the service, and then click the Startup type dropdown and choose disable, click apply, then click OK.
2) Running Adobe Flash in your Internet Browsers could also be the culprit.
In Chrome Browser’s address bar, type chrome://plugins/ and hit enter.
Do a find on Adobe Flash Player and disable the player to see if that resolves the issue.
3) Identify if you are running the inbox AHCI driver (StorAHCI.sys):
Open an elevated command prompt. Type the following command in the command prompt window and hit Enter: devmgmt.msc
Under IDE ATA/ATAPI Controllers right-click on the AHCI controller node and select Properties. This node is usually called “Standard SATA AHCI Controller.
Navigate to the driver tab and click Driver Details. If you see “StorAHCI.sys” in the list, you are running the inbox driver, and so, disable MSI for the controller by doing the following:
a) In the same properties window, click the Details tab and select “Device instance path” from the Property drop-down menu. Note this path for you need to find it in the Registry
b) Open the registry editor by typing regedit in the previously opened command prompt.
Navigate to:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\PCI<AHCI Controller>\Device Parameters\Interrupt Management\MessageSignaledInterruptProperties,
and replace <AHCI Controller> with your device instance path you noted above. Change the value of the MSISupported key from “1” to “0”.
If you don’t know which controller your boot device is attached to, repeat this process for all AHCI controllers found under the Details tab.
4) A memory leak on the Microsoft side with the Windows Network Data Usage Monitor (Ndu) driver could be the culprit. You can disable this driver in the Registry as follows:
Hkey_Local_Machine\System\ControlSet001\Services\Ndu
Change the “Start” DWord from 2 to 4
5) Disable Microsoft Telemetry. Open an elevated command prompt and enter the following one at a time.
sc delete DiagTrack sc delete dmwappushservice echo "" > C:\ProgramData\Microsoft\Diagnosis\ETLLogs\AutoLogger\AutoLogger-Diagtrack-Listener.etl reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows\DataCollection" /v AllowTelemetry /t REG_DWORD /d 0 /f If this doesn't work, then disable it from the Task Scheduler. 1) Click Start, type task scheduler and press Enter. 2) On the Task Scheduler window, go to this path: Task Scheduler Library\Microsoft\Windows\Application Experience. 3) On the Application Experience folder, look for Microsoft Compatibility Appraiser. 4) Right-click Microsoft Compatibility Appraiser and select Disable. 5) Restart your computer.
