Sometimes it happens when the program doesn’t get suspended and causes high CPU and Disk usage on your computer. There are many services which use RPC such as Windows Update, OneDrive or Dropbox etc. We can try looking into these services and determine which process is causing the problem.
Solution 1: Disabling OneDrive
OneDrive is known to cause high CPU usage in a lot of cases. It constantly syncs with the cloud server and if any configuration isn’t done right, it causes a lot of disk usage. We can try disabling OneDrive properly and check if the problem still persists. You can always revert the changes if this doesn’t work for you.
If you don’t find OneDrive listed in your programs list, we can try disabling it.
Now restart your computer and check if the disk/CPU usage is fixed.
Solution 2: Disabling Windows Update
Windows, when searching for updates, also uses RPC protocol. Even when updates are installed on your PC, Windows keeps searching for more available updates to download. This can sometimes keep going in a loop causing it to consume high CPU/Disk usage. We can try disabling Windows Update and check if the problem still persists.
If Windows update still doesn’t shut down properly and you think it is the culprit, we can try disabling the service permanently until you want to turn it on again. We will also delete already downloaded update files. Now we will navigate to Windows Update directory and delete all the updated files already present. Open your file explorer or My Computer and follow the steps. C:\Windows\SoftwareDistribution
Solution 3: Using Deployment Image Servicing and Management
DISM is a command-line tool which is used to service your operating system. We can try executing this command and if there are any discrepancies, they will be fixed. Note: Windows update is required to execute this solution. If your windows update is broken/not working, you might want to consider restoring your OS from a previous restore point. DISM.exe /Online /Cleanup-image /Restorehealth
sfc /scannow
Solution 4: Checking Third-Party Applications
There are many reports when applications such as Google Chrome, Dropbox, Xbox etc. cause problems in the disk usage. Each computer configuration is different hence we cannot diagnose exactly which application is causing trouble. Make an educated guess, disable each of these applications properly and check your CPU/Disk usage. Give more priority to an application which requires frequent internet access for sync purposes. Here are some applications and the fixes:
If you have Google Chrome, reinstall it.Disable Dropbox properly and disable the application from launching on startup.Turn off Xbox application.
Solution 5: Disabling Windows Defender
Many users reported that Windows Defender was causing the problem. The application kept searching for virus definitions and in turn, caused high CPU usage by running RPC protocol.We can try to disable the antivirus utility and check if the problem still persists.
After completing the above steps, your Windows Defender should be turned off. Restart your computer and check if the Disk/CPU usage got fixed.
