Cross-Device Experience Host Not Installing Updating? Fix

If you see “Cross Device Experience Host” stuck at “Installing” or “Updating” in the Microsoft Store, the fix is usually to clear the Store cache, run the Windows Update troubleshooter, or manually reset the app. This component is a background system app that syncs your activity and clipboard across your Windows devices, and it sometimes fails to update due to corrupted cache files or a stalled Windows Update service. Below are the exact steps to resolve it, plus what this app actually does and why it matters.

What Is Cross Device Experience Host?

Cross Device Experience Host (CDEH) is a built-in Windows component that powers features like Phone Link (formerly Your Phone), Continue on PC, and cross-device clipboard sharing. It runs in the background and communicates with Microsoft’s servers to sync your browsing sessions, notifications, and copied text between your PC and mobile devices. It’s not a user-facing app—you won’t see a window for it—but it’s essential for those cross-device features to work.

Because it’s a system component, it updates automatically through the Microsoft Store or Windows Update. When it gets stuck, you might notice that Phone Link won’t connect, or that “Continue on PC” stops working. The update failure itself usually appears in the Microsoft Store under “Downloads” with a perpetual “Installing” or “Updating” status.

Why Does It Get Stuck?

The most common causes are:

• Corrupted Store cache – Temporary files that confuse the update process.
• Windows Update service hiccup – The background service that handles app updates may be paused or stalled.
• Conflicting background tasks – Another process (like an antivirus) may be interfering.
• Pending system reboot – Windows may be waiting for a restart to finish a previous update.
• Outdated Windows version – Some CDEH updates require a recent Windows 11 or 10 build.

How to Fix It (Step-by-Step)

Try these in order—most users resolve it with the first step.

1. Clear the Microsoft Store Cache

1. Press Win + R, type wsreset.exe, and press Enter.
2. A blank Command Prompt window will open; wait for it to finish and the Store to launch automatically.
3. Go to Library in the Store and check if the update now proceeds.

2. Run the Windows Update Troubleshooter

1. Open Settings → System → Troubleshoot → Other troubleshooters.
2. Select Windows Update and click Run.
3. Follow the prompts; it will detect and fix common update issues.

3. Restart the Windows Update Service

1. Press Win + R, type services.msc, and press Enter.
2. Find Windows Update, right-click it, and select Restart.
3. Also restart Microsoft Store Install Service if present.

4. Reset the App via PowerShell

If the above fails, reset the app package itself:

1. Right-click the Start button and select Windows Terminal (Admin) or PowerShell (Admin).
2. Run this command:
   Get-AppxPackage Microsoft.CrossDeviceExperience | Reset-AppxPackage
3. Wait for it to complete, then restart your PC.

5. Check for Windows Updates

1. Go to Settings → Windows Update → Check for updates.
2. Install any pending updates, then restart.

If none of these work, a full Store reset via wsreset.exe plus a reboot usually does the trick. In rare cases, you may need to manually download the update from the Microsoft Store’s web page, but that’s only necessary if the package is corrupted beyond repair.

Common Mistakes and Misconceptions

“It’s a virus.” No. Cross Device Experience Host is a legitimate Microsoft component. If you see it in Task Manager, it’s normal. However, a malware infection can disguise itself with a similar name—check that the file path is C:\Windows\SystemApps\Microsoft.CrossDeviceExperience_*.

“I should uninstall it.” You can’t uninstall it permanently—it’s a system component. You can disable it, but that will break Phone Link and cross-device features. Better to fix the update.

“It’s using too much CPU.” Normally it uses almost nothing. If it’s pegging your CPU, it may be stuck in a loop—the reset steps above will fix that.

How to Prevent Future Update Failures

• Keep Windows Update enabled and install updates regularly.
• Don’t disable the Microsoft Store or its services—many system apps rely on it.
• If you use third-party “debloat” scripts, avoid removing system apps like CDEH.
• Periodically run wsreset.exe if you notice Store downloads hanging.

Alternatives if It Still Won’t Update

If after all steps the update still fails, you have two practical options:

• Wait for the next Windows cumulative update – Microsoft often bundles fixes for system app updates into monthly patches.
• Use the “Continue on PC” feature without Phone Link – You can still share links from your phone via the Share menu and select “Continue on PC” even if CDEH is outdated, though it may be less reliable.

If Phone Link is your primary use, you can also use the web-based version at phone link in your browser, which doesn’t rely on the local app.

Frequently Asked Questions

Is Cross Device Experience Host safe?

Yes, it’s a legitimate Microsoft system app. As long as it’s located in the SystemApps folder and signed by Microsoft, it’s safe. If you’re unsure, right-click it in Task Manager and select “Open file location” to verify the path.

Can I disable Cross Device Experience Host?

Technically yes, via Settings → Apps → Installed apps, but it will break Phone Link and cross-device clipboard. It’s not recommended unless you never use those features. If you do disable it, Windows may re-enable it after a major update.

Why does it keep updating every month?

Microsoft updates system components like CDEH regularly to fix bugs and add features. These updates are usually small and silent, but they may show up in the Store if they’re delivered that way. It’s normal.

Will resetting the app delete my data?

No. Resetting CDEH only clears its local configuration and temporary files. Your phone link connections and clipboard history (if you have “sync across devices” enabled) are stored in the cloud and will re-sync.

What if the fix doesn’t work?

If you’ve tried all steps and the update still fails, the issue may be deeper—like a corrupted Windows profile or a failing disk. Try creating a new local user account and see if the update works there. If it does, you may need to migrate your data.
