Fix OneDrive Processing Hundreds of Thousands of Changes on Windows

Maira Mehtab Sep 22, 2026 869 views

Question details

The user's OneDrive application is continuously processing an abnormally large number of changes (e.g., over 250,000), causing locally updated files to remain in a pending state without syncing.

Product: Microsoft OneDrive
Device & OS: Windows
Scenario: Syncing locally updated files to the cloud while using a Windows device.
Observed behavior: OneDrive gets stuck endlessly processing changes, preventing local document updates from successfully uploading and leaving them marked as pending.

Before you start

Before proceeding, ensure your Windows device is connected to a stable internet connection and keep your Microsoft account login credentials handy, as you may need to sign back into your account during the troubleshooting process.

Solution 1Recommended

Reset the OneDrive Sync Application

Resetting the OneDrive application clears the current sync cache and forces the app to rebuild its sync queue, which usually resolves infinite processing loops.

A reset is the most effective way to resolve stubborn sync issues without affecting your actual data. This process forces OneDrive to perform a full scan of your files and re-sync them from scratch.

Open the Run dialog

Press the Windows Key + R simultaneously on your keyboard to open the Run dialog box.

Execute the reset command

Type the following command into the text box: %localappdata%\Microsoft\OneDrive\onedrive.exe /reset and press Enter or click OK.

Restart OneDrive manually if needed

The OneDrive cloud icon in your system tray should disappear and reappear after a minute or two. If the icon does not return, open the Start menu, search for OneDrive, and click it to launch the application.

No Data Loss: Resetting OneDrive only resets the application's internal sync settings. It will not delete any of your locally saved files or data stored in the cloud.

Solution 2

Unlink and Re-link Your OneDrive Account

If resetting doesn't work, unlinking your PC from OneDrive and signing back in establishes a fresh connection to Microsoft's servers, clearing persistent file processing errors.

Solution 3

Update Windows and the OneDrive Client

Running outdated software can cause compatibility issues resulting in infinite sync processing. Keeping Windows and OneDrive updated ensures bug fixes are applied.

Frequently Asked Questions

Why is OneDrive stuck processing hundreds of thousands of changes?

This usually occurs when the internal sync queue gets corrupted, a file has conflicting metadata, or temporary caching issues arise. It can also happen naturally if you recently moved, renamed, or deleted a massive batch of files all at once.

Will I lose my pending local files if I reset OneDrive?

No, resetting or unlinking the OneDrive app does not delete your local files or cloud data. The reset simply forces the application to verify and rebuild its sync list. However, it is always a good practice to manually copy heavily edited files that say 'pending' to a different local folder as a backup before resetting.

How long does OneDrive normally take to process changes?

Typically, processing a few file changes takes only a few seconds to a minute depending on your internet speed. If OneDrive shows hundreds of thousands of changes and is stuck for hours without progressing, the sync engine has stalled and requires troubleshooting.

Does unlinking my PC from OneDrive delete downloaded files?

No. When you unlink your PC, it just stops the synchronization process and signs you out of the OneDrive application. All the files that were already downloaded to your hard drive remain intact locally, and your cloud files stay safe on Microsoft's servers.
