What is edge-sync.exe?
edge-sync.exe is the Edge Data Synchronization component built into Microsoft Edge. It runs in the background to keep your bookmarks, passwords, history, and settings consistent across devices when you sign in with your Microsoft account.
The edge-sync service uses a client-side sync protocol to push and pull changes to the Edge cloud. It runs as a background process, coordinating per-item sync across profiles while preserving user privacy with encryption.
Quick Fact: Edge Sync began with Edge Chromium to provide cross-device continuity for user data without requiring third-party sync tools.
Types of Edge Sync Processes
- Sync Core: Core data pipeline coordinating changes across devices
- Credential Sync: Password and sign-in data synchronization
- History Sync: Browsing history and visited sites synchronization
- Settings Sync: Edge settings and preferences synchronization
- Extensions Sync: Extension state and enable/disable settings sync
- Telemetry Sync: Usage telemetry and diagnostic data submission
Is edge-sync.exe Safe?
Yes, edge-sync.exe is safe when it is the legitimate file from Microsoft downloaded from official sources (microsoft.com or pre-installed by system builder).
Is edge-sync.exe a Virus or Malware?
The real edge-sync.exe is NOT a virus. However, malware may imitate names to mislead users.
How to Tell if edge-sync.exe is Legitimate or Malware
- File Location:: Must be in
C:\Program Files (x86)\Microsoft\Edge\Application\edge-sync.exe or C:\Program Files\Microsoft\Edge\Application\edge-sync.exe. Any edge-sync.exe elsewhere is suspicious.
- Digital Signature:: Right-click edge-sync.exe in File Explorer → Properties → Digital Signatures. Should show "Microsoft Corporation".
- Resource Usage:: Normal usage is 0-5% CPU and 50-150 MB memory; constant high usage outside Edge session is suspicious.
- Behavior:: Edge Sync should run when Edge is signed in and syncing; no persistent background activity when Edge is closed is expected.
Red Flags: If edge-sync.exe is located in unusual folders (Like Temp, AppData, or System32), runs when Edge is not open, has no digital signature, or uses excessive resources constantly, scan with antivirus software. Beware of similarly-named files.
Why Is edge-sync.exe Running on My PC?
edge-sync.exe runs to keep Edge browser data in sync across devices when you sign in to your Microsoft account or when Sync is enabled in your profile.
Reasons it's running:
- Active Sync Use: You are actively signing into Edge and have Sync enabled, causing per-item sync across devices
- Background Data Sync: Edge periodically pushes and pulls bookmark, password, and history changes in the background
- Startup/Login: Edge Sync may start when Windows boots or you log into a Microsoft account on the device
- Cross-Device Sync: Changes on another device propagate to this machine via the Edge Sync cloud
- Policy or Profile: Enterprise or organizational policies may enable aggressive sync to keep profile data aligned
Can I Disable or Remove edge-sync.exe?
Yes, you can disable edge-sync.exe. It's safe to pause or uninstall Edge Sync if you do not require cross-device synchronization.
How to Stop edge-sync.exe
- Disable Sync in Edge: Open Edge → Settings → Profiles → Sync and turn off data types you don't want to sync, or sign out
- End Sync Tasks: In Task Manager, locate edge-sync.exe and end the task
- Disable Startup: Task Manager → Startup tab → Disable Microsoft Edge (Edge Sync may be bundled)
- Stop Background Apps: Edge Settings → System → Disable 'Continue running background apps when Edge is closed'
