Hi gogo _r,

Welcome to Microsoft Q&A!

I'm sorry to hear that you're encountering an annoying error. The .exe belongs to Cross‑Device Experience Host, used by features that connect your PC to your phone (e.g. Phone Link). This error message indicates that Windows is trying to run the Service with an incorrect command-line parameter, often due to a corruption or misconfiguration in the Windows Registry. Here's something you should do:

1 - If the error appears upon you clicking a shortcut or at sign‑in:

• Open Settings > Apps > Startup > turn OFF anything pointing to Cross Device Service
• Open Task Scheduler > Task Scheduler Library > Microsoft > Windows > ConnectedDevicesPlatform (or similar) > disable any custom or failing task that tries to launch it.
• Don’t try to run anything inside C:\Program Files\WindowsApps\… by hand.

2 - Check the Phone Link app:

• Open Microsoft Store > Library > Get updates
• Open Settings > System > System components > Phone Link > three-dot > Advanced options:
  • Scroll down, click Terminate > Repair.
  • If the issue remains, choose Reset.

3 - Re‑register Cross Device app package:

• Open Windows PowerShell (Admin) > Run Get-AppxPackage -AllUsers CrossDevice | Reset-AppxPackage
• If the above is not available, run this instead: Get-AppxPackage *CrossDevice* | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
• Restart your computer and see if the issue persists.

4 - Clear possible corruptions:

• Open Command Prompt (Admin) > Enter the following prompts:
  • DISM /Online /Cleanup-Image /RestoreHealth
  • sfc /scannow
• Press Win + R > type wsreset.exe > Enter

I hope the information above helps. Feel free to let me know if you need clarification on any steps or if the issue persists after applying the changes. Consider sharing when and where the message appears (on boot, after sleep, only after clicking a shortcut, etc.) in the next reply, so we can narrow down the causes and find more suitable solutions.This answer has been auto-translated.
