What is PhoneExperienceHost.exe?
PhoneExperienceHost.exe is the Windows system component that hosts the Phone Experience integration, enabling Your Phone/Phone Link features. It coordinates data between your PC and connected mobile devices, including notifications, messages, and content viewing.
It runs as a separate process to isolate phone-related tasks from the main user interface, using Windows services to handle background syncing and UI elements for the phone experience.
Quick Fact: Phone Experience Host helps deliver cross-device features like notifications and messaging without tying up the main UI thread.
Types of Phone Experience Host Components
- Main Host UI: User interface shell for phone-related features and settings
- Phone Link Service: Backend service coordinating phone pairing and data transfer
- Notification Bridge: Brings phone notifications to the PC in near real-time
- Background Sync Task: Background tasks for phone integration
- Content Mirroring: Streams phone content (photos, messages) to the PC when requested
- Security Sandbox: Isolates phone data to protect the host system
Is phoneexperiencehost.exe Safe?

Is phoneexperiencehost.exe a Virus or Malware?
The real file is not a virus. Malware can mimic names, so verify the path and signature.
How to Tell if phoneexperiencehost.exe is Legitimate or Malware
- File Location: Must be in
C:\Windows\System32\PhoneExperienceHost.exe. Any file with this name elsewhere is suspicious.
- Digital Signature: Right-click the file in File Explorer → Properties → Digital Signatures. Should show a valid signature from "Microsoft Corporation".
- Resource Usage: Normal usage is low CPU and memory when idle (varies with activity). Abnormal sustained high usage by a non-Microsoft signer is suspicious.
- Behavior: Should only be active when Phone Link/Your Phone features are used or configured to run in the background. Constant activity when idle warrants malware scanning.
Red Flags: If phoneexperiencehost.exe is found outside the System32 folder, lacks a valid Microsoft signature, or uses persistent high resources without phone integration active, scan with trusted antivirus and review Windows Features.
