What is edge-sync.exe?
edge-sync.exe is the background service for Microsoft Edge data synchronization. It runs to keep your bookmarks, saved passwords, favorites, form data, and browser settings in sync across devices when you sign in with a Microsoft account. It may run intermittently during sync cycles.
edge-sync.exe coordinates Edge's cloud sync via background threads, tracking local changes and server updates. It uses HTTPS, token authentication, and a local data store to apply updates without interrupting browsing.
Quick Fact: Edge Sync was designed for cross-device consistency; changes propagate during idle moments to minimize user disruption.
Types of Edge Processes
- Background Sync Process: Runs in the background to handle cloud sync tasks
- Browser Process: UI and rendering for Edge when open
- Network/Service Tasks: Helper tasks for connectivity and token refresh
Is edge-sync.exe Safe?
Yes, edge-sync.exe is Safe when it’s the legitimate file from Microsoft, installed as part of Edge. Ensure it’s located in the proper Edge directory and digitally signed.
Is edge-sync.exe a Virus or Malware?
The real edge-sync.exe is NOT a virus. Malware may masquerade with similar names, so verify location and signature.
How to Tell if edge-sync.exe is Legitimate or Malware
- File Location: Must be in
C:\Program Files\Microsoft Edge\Application\EdgeSync.exe or C:\Program Files (x86)\Microsoft Edge\Application\EdgeSync.exe. Any edge-sync.exe elsewhere is suspicious.
- Digital Signature: Right-click EdgeSync.exe in its folder → Properties → Digital Signatures. Should show "Microsoft Corporation".
- Resource Usage: Normal usage is 0-4% CPU and 20-120 MB memory; constant high usage is suspicious.
- Behavior: EdgeSync should not cause UI lag; if you see edges of unusual network activity outside Edge, investigate.
Red Flags: If edge-sync.exe is located outside the Edge directory (e.g., Temp or AppData), runs when Edge isn’t open, has no digital signature, or consumes resources constantly, scan with antivirus and verify Edge integrity.
Why Is edge-sync.exe Running on My PC?
edge-sync.exe runs to keep Edge data in sync across devices, and may run when a sync operation or a sign-in event occurs.
Reasons it's running:
- Active Edge Sync: You are signed into Edge and data changes are being synchronized with the cloud.
- Background Sync Enabled: Edge is configured to sync in the background, so EdgeSync runs even when the browser is closed.
- Account Changes: Sign-in or password changes trigger token refresh and data sync tasks.
- Edge Updates: New Edge versions may include Sync service updates that briefly start EdgeSync.
- Startup/Shutdown Sync: Edge may perform initial sync on startup and final sync during shutdown to preserve state.
Can I Disable or Remove edge-sync.exe?
Yes, you can disable edge-sync.exe. Disabling may stop cross-device sync; you can turn off sync in Edge settings or disable the startup entry.
How to Stop edge-sync.exe
- Pause or Disable Sync: Open Edge settings → Profiles → Sync and disable sync to stop data exchange.
- Close Edge: Exit Edge completely; EdgeSync will pause when Edge is closed if background sync is off.
- Prevent Startup: Open Task Manager → Startup tab → Disable Microsoft Edge (EdgeSync included).
- Stop Background Apps: Settings → System → Background apps → Turn off "Continue running background apps when Microsoft Edge is closed"
- Firewall Permissions: Ensure EdgeSync isn’t blocked; adjust firewall rules if necessary.
How to Uninstall Edge Sync Components (Edge browser)
- ✔ Windows Settings → Apps → Apps & Features → Microsoft Edge → Modify/Repair (not typical uninstall); Edge data stays in profile
- ✔ Control Panel → Programs → Uninstall a program → Microsoft Edge → Uninstall
- ✔ Note: Uninstalling Edge is not required; you can simply disable sync or keep Edge uninstalled.
Common Problems: Edge Sync
If edge-sync.exe is causing issues, review these specific Edge Sync scenarios and fixes.
Common Causes & Solutions
- Sync stops or runs slowly: Check your Microsoft account sign-in status, ensure stable network, and pause/resume sync in Edge.
- High background CPU usage: Disable nonessential sync categories (e.g., passwords or settling) and limit Edge background tasks.
- Sync data not propagating across devices: Sign out and back in, verify the same Microsoft account, and ensure devices are connected.
- EdgeSync blocked by firewall or antivirus: Add EdgeSync.exe to allowed list and ensure it can reach Microsoft cloud endpoints.
- Corrupted Edge profile data: Create a fresh profile or reset sync data from Edge settings; backup important data.
- Edge updates fail: Update Edge to latest version and retry sync after restart.
Quick Fixes:
1. Open Edge, go to Settings → Profiles → Sync and turn off then on again
2. Check network connectivity and retry sync
3. Ensure Edge is updated to the latest version
4. Check firewall/antivirus allowances for EdgeSync.exe
5. Clear Edge cache: edge://settings/clearBrowsingData
