How to Fix Microsoft.SharePoint.exe High CPU and SSD Usage

Product: Microsoft OneDrive
Device & OS: Windows
Scenario: Syncing shared business content or SharePoint libraries to a local computer via OneDrive.
Observed behavior: Microsoft.SharePoint.exe consumes excessive CPU and SSD resources in the background, drastically slowing down the PC, even when SharePoint is not installed as a standalone application.

Before you start

Open Task Manager and navigate to the Details tab to verify if Microsoft.SharePoint.exe is currently running and actively consuming high disk or CPU resources before proceeding with the troubleshooting steps.

Solution 1Recommended

Verify Process Location and Stop Unnecessary Syncing

Confirm the process belongs to OneDrive and stop syncing large or unnecessary SharePoint libraries to reduce disk usage.

Even if you have not installed SharePoint directly, Microsoft.SharePoint.exe is bundled with the OneDrive sync client. It activates when you sync a shared library or are invited to collaborate on a SharePoint site.

Open Task Manager Details

Press Ctrl + Shift + Esc to open Task Manager, and navigate to the Details tab.

Verify File Location

Right-click Microsoft.SharePoint.exe and select 'Open file location'. Confirm it is located within the C:\Program Files\Microsoft OneDrive directory to ensure it is legitimate.

Open OneDrive Settings

Click the OneDrive cloud icon in your Windows system tray, click the gear icon, and select 'Settings'.

Stop Syncing Libraries

Navigate to the 'Account' tab to view all synced locations. Click 'Stop sync' next to any shared business folders or SharePoint libraries you no longer need to keep synchronized locally.

Verify Process Location and Stop Unnecessary Syncing

Performance Improvement: Stopping the synchronization of massive external libraries will immediately halt the SSD input/output drain caused by the SharePoint executable.

Solution 2

Reset Microsoft OneDrive

Resetting OneDrive can resolve underlying sync engine issues causing high background resource consumption.

Solution 3

Run the System File Checker (SFC)

Check and repair any corrupted Windows system files that might be interfering with background processes like OneDrive.

Frequently Asked Questions

Why is Microsoft.SharePoint.exe on my PC if I didn't install it?

The executable is automatically bundled as a component of Microsoft OneDrive. It runs in the background when OneDrive is configured to sync files from a SharePoint site or shared business folders you have been invited to collaborate on, even if the standalone SharePoint application was never installed.

Can I safely end the Microsoft.SharePoint.exe process?

Yes, you can safely end the process via Task Manager to temporarily stop high SSD or CPU usage. However, it will likely restart automatically the next time OneDrive attempts to sync those files. To fix it permanently, you must adjust your OneDrive sync settings and remove the library.

How do I know if Microsoft.SharePoint.exe is a virus?

Right-click the process in the Task Manager Details tab and select 'Open file location'. If it is located within the C:\Program Files\Microsoft OneDrive directory (or C:\Users\<username>\AppData\Local\Microsoft\OneDrive\), it is a legitimate Microsoft process. If located elsewhere, you should run a full antivirus scan.
