File Description: iesettingsync.exe

iesettingsync.exe is a legitimate executable file developed by Microsoft Corporation. It is a core component of the Windows operating system, specifically tied to Internet Explorer and system sync settings.

Function: It synchronizes Internet Explorer settings (like favorites, history, and passwords) across your different Windows devices using your Microsoft account.
Impact: Disabling or deleting it can stop your browser preferences from syncing correctly between devices.

Standard File Location

The genuine file is always located in the Windows system directory.

C:\Windows\System32\

Safety Check: If you find this file in any other folder (like Temp or your user profile folder), it is likely malware masking itself under a legitimate name. Run a full antivirus scan immediately.

How to Fix iesettingsync.exe Errors (Without Downloading Anything)

Errors usually occur because the file is corrupted, missing, or blocked by system conflicts. You can fix these issues using built-in Windows tools.

Method 1: Run the System File Checker (SFC)

This built-in tool scans your system for corrupted or missing Windows files and replaces them automatically using local backup files.

Press the Windows Key.
Type cmd.
Right-click Command Prompt and select Run as administrator.
Type sfc /scannow and press Enter.
Wait for the scan to finish (10–20 minutes).
Restart your computer.

Method 2: Run the DISM Tool

If the SFC tool cannot fix the problem, use the Deployment Image Servicing and Management (DISM) tool to repair the underlying system image.

Open Command Prompt as administrator (same as Method 1).
Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.
Let the tool repair your system files using your Windows local image.
Run sfc /scannow one more time after DISM finishes.
Restart your computer.

Method 3: Turn Off Internet Explorer Syncing

If the error persists and you do not need to sync Internet Explorer settings across multiple computers, you can turn this feature off to stop the error from appearing.

Open the Settings app (Press Windows Key + I).
Click on Accounts.
Click on Sync your settings (or Backup depending on your Windows version).
Locate the Internet Explorer settings toggle.
Switch the toggle to Off.
