What Is Microsoft Phone Link?
Microsoft Phone Link is Microsoft's app for linking a Windows PC with an Android phone, and in some cases an iPhone with more limited features. It can show phone notifications, messages, calls, recent photos and other cross-device features inside Windows.
The process name phoneexperiencehost.exe belongs to this app. It is not a core part of Windows startup or system stability. If you never use Phone Link, it is usually just an optional background app.
Is It Safe?
Yes, if it is the real Microsoft file. With the publisher listed as Microsoft Corporation, Phone Link is normally safe.
Because malware can use familiar names, do a quick check if you are unsure:
- In Task Manager, right-click
phoneexperiencehost.exeand choose Open file location. - The real file should open from a Microsoft app folder under
C:\Program Files\WindowsApps\. - Open the file's Properties and check that the digital signature is from Microsoft.
If the file runs from a temporary folder, Downloads, AppData malware locations, or another unusual path, treat it as suspicious and investigate further.
Should I Disable It at Startup?
Usually, yes, if you do not actively use Phone Link. Disabling it at startup is generally safe. The app should still open normally when you launch it yourself.
Keep it enabled if you want these features available as soon as you sign in:
- phone notifications on your PC
- message and call syncing
- quick access to recent phone photos
- ongoing device connection in the background
Disable it if you do not use those features or want fewer background apps starting with Windows. This will not harm Windows itself.
Why Is It Using High CPU or Memory?
Phone Link may use more CPU or memory when it is:
- pairing with a phone
- syncing notifications, messages or photos
- retrying a broken Bluetooth or network connection
- stuck after an app update or Windows sign-in change
If usage stays high for more than a few minutes, try this:
- open Phone Link and let it finish syncing
- disconnect and reconnect your phone
- restart the app or restart Windows
- check for updates in the Microsoft Store
- sign out of Phone Link and pair again if the connection seems broken
If you do not use it, disabling its background startup is the simplest fix.
How to Disable or Remove It
To stop it from launching with Windows, use Settings > Apps > Startup and turn off Phone Link if it appears there. You can also disable it from Task Manager's Startup apps list.
If you want to remove it entirely, uninstall Phone Link from Settings > Apps > Installed apps if Windows allows it on your system. On some Windows setups, Microsoft apps may be managed differently or reinstalled by updates.
Do not delete app files by hand from WindowsApps.

Frequently asked questions
- Will disabling Phone Link break Windows?
- No. Phone Link is not required for Windows to run. You will only lose its phone sync features until you open or re-enable the app.
- Can I end phoneexperiencehost.exe?
- Usually yes, if Phone Link is stuck or using too many resources. Ending it may close syncing or notifications until the app starts again.
- Why does Phone Link come back after an update?
- Some Microsoft apps can be updated or re-enabled by Windows or the Microsoft Store. If that happens, check your Startup settings again and turn it off if you do not want it running in the background.
