StartMenuExperienceHost.exe is a legitimate Windows process that controls your Start Menu experience in Windows 10 and 11. Microsoft created this program to handle the visual interface and functionality when you click the Start button.
This process runs in the background and manages:
- Start Menu appearance and animations
- Tile organization and live tile updates
- Search box functionality within the Start Menu
- Context menus when you right-click Start Menu items
The file typically uses between 20MB and 60MB of memory during normal operation. You’ll find it located in C:\Windows\SystemApps\Microsoft.Windows.StartMenuExperienceHost_cw5n1h2txyewy.
Why Is StartMenuExperienceHost.exe Running on My Computer?
This process starts automatically when Windows boots up because the Start Menu is a core component of your operating system. Even if you don’t actively use the Start Menu, Windows keeps this process ready so it responds instantly when needed.
Normal behavior includes:
- Running constantly in the background
- Brief CPU spikes when you open the Start Menu
- Memory usage that stays relatively stable
- Automatic restart if it crashes
The process appears in Task Manager under “Background processes” and is completely safe. It’s digitally signed by Microsoft Corporation.
Common Problems with StartMenuExperienceHost.exe
High CPU Usage
When StartMenuExperienceHost.exe uses excessive CPU (above 30% for extended periods), something is wrong. This often happens due to:
- Corrupted Start Menu cache files
- Conflicts with third-party Start Menu customization tools
- Windows update issues that damaged system files
- Malware disguised with a similar name
High Memory Consumption
Memory usage above 200MB indicates a problem. Common causes include:
- Memory leaks from buggy Windows updates
- Too many live tiles trying to update simultaneously
- Corrupted user profile data
- Multiple instances running when only one should exist
Start Menu Not Opening
The most frustrating issue occurs when clicking the Start button does nothing. This happens when StartMenuExperienceHost.exe crashes or fails to initialize properly.
Repeated Crashing
If you see “StartMenuExperienceHost.exe has stopped working” messages repeatedly, your system has deeper issues that need attention.

How to Fix StartMenuExperienceHost.exe High CPU Usage
Method 1: Restart the Process
The simplest solution often works.
- Press
Ctrl + Shift + Escto open Task Manager - Click “More details” if you see the simplified view
- Find “Start” or “StartMenuExperienceHost.exe” under Background processes
- Right-click the process and select “End task”
- Open the Start Menu again (it will restart automatically)
This clears temporary glitches without requiring a full system restart.
Method 2: Clear Start Menu Cache
Corrupted cache files cause most persistent CPU problems.
- Press
Win + Rto open Run dialog - Type
%localappdata%and press Enter - Navigate to
Packages\Microsoft.Windows.StartMenuExperienceHost_cw5n1h2txyewy - Find the folder named “TempState” or “LocalState”
- Delete all files inside these folders (not the folders themselves)
- Restart your computer
Windows rebuilds the cache automatically with fresh data.
Method 3: Run System File Checker
Damaged system files prevent proper operation.
- Right-click the Start button
- Select “Windows Terminal (Admin)” or “Command Prompt (Admin)”
- Type
sfc /scannowand press Enter - Wait 15-30 minutes for the scan to complete
- Restart if the tool finds and repairs corrupted files
Method 4: Disable Live Tiles
Live tiles constantly update and can overload the process.
- Right-click any live tile in your Start Menu
- Select “More” then “Turn live tile off”
- Repeat for all tiles showing active content
- Check if CPU usage drops
Method 5: Create a New User Profile
Corrupted user profiles cause persistent issues.
- Go to Settings > Accounts > Family & other users
- Click “Add someone else to this PC”
- Create a new local account
- Sign out and log into the new account
- Check if the problem persists
If the new profile works normally, your old profile has corrupted data that’s hard to repair directly.
How to Fix Start Menu Not Opening

Performance Impact and Resource Usage
Understanding normal resource usage helps you identify problems quickly.
| System State | CPU Usage | Memory Usage | Disk Activity |
|---|---|---|---|
| Idle (Start Menu closed) | 0-2% | 15-40MB | None |
| Opening Start Menu | 5-15% spike | 40-70MB | Low |
| Actively browsing tiles | 5-10% | 50-80MB | Low-Medium |
| Problem state | 20%+ constant | 150MB+ | High |
On modern computers with SSDs and 8GB+ RAM, you should never notice StartMenuExperienceHost.exe affecting performance during normal use.
Disabling or Removing StartMenuExperienceHost.exe
You cannot and should not remove this file. It’s a protected system component that Windows needs to function properly.
Attempting to delete or disable StartMenuExperienceHost.exe causes:
- Complete loss of Start Menu functionality
- Inability to search for programs or files
- System instability and potential boot issues
- Automatic restoration by Windows during updates
If you dislike Windows’ default Start Menu, consider these alternatives instead:
- Use third-party Start Menu replacements like Start11 or Open-Shell
- Switch to Windows 10 LTSC edition (for advanced users)
- Learn keyboard shortcuts to reduce Start Menu dependency
- Pin frequently used programs to the taskbar
Third-Party Start Menu Tools and Conflicts
Alternative Start Menu programs sometimes conflict with StartMenuExperienceHost.exe because both try to control the same functionality.
Popular alternatives include:
- Start11 by Stardock
- Open-Shell (formerly Classic Shell)
- StartIsBack
- StartAllBack
These tools typically disable or override Windows’ native Start Menu. If you experience problems after installing such software:
- Temporarily disable the third-party tool
- Check if StartMenuExperienceHost.exe behaves normally
- Update the third-party software to the latest version
- Check the software’s forums for known compatibility issues
- Consider uninstalling if conflicts persist
Windows Central maintains a comprehensive guide on customizing the Windows Start Menu that covers both native options and third-party tools.

Summary
StartMenuExperienceHost.exe is an essential Windows process that manages your Start Menu. While it occasionally causes high CPU usage or prevents the Start Menu from opening, most problems resolve quickly with simple fixes like restarting the process, clearing cache files, or running system repair tools.
The file itself is not dangerous, uses minimal resources during normal operation, and cannot be safely removed from your system. If you experience persistent issues after trying the troubleshooting steps in this guide, consider creating a new user profile or performing a Windows repair installation.
Regular system maintenance and keeping Windows updated prevent most StartMenuExperienceHost.exe problems before they occur.
Frequently Asked Questions
Can I end StartMenuExperienceHost.exe in Task Manager permanently?
No, Windows automatically restarts this process because the Start Menu requires it. Ending the task temporarily resolves glitches, but the process returns immediately when you open the Start Menu again or after a system restart.
Why does StartMenuExperienceHost.exe use more memory over time?
Memory leaks from buggy Windows updates or corrupted cache files cause gradual memory usage increases. Restart the process or clear the Start Menu cache to reset memory consumption to normal levels.
Does disabling live tiles reduce StartMenuExperienceHost.exe resource usage?
Yes, live tiles constantly update in the background, which requires processing power and memory. Disabling all live tiles typically reduces resource usage by 20-30%, particularly on systems with limited RAM or slower processors.
What’s the difference between StartMenuExperienceHost.exe and SearchApp.exe?
StartMenuExperienceHost.exe controls the Start Menu interface and tiles, while SearchApp.exe handles the Windows Search functionality. Both processes work together when you search from the Start Menu, but they serve different purposes.
Will upgrading from Windows 10 to Windows 11 fix persistent StartMenuExperienceHost.exe issues?
Sometimes yes, because Windows 11 uses a simpler Start Menu design that reduces complexity. However, if underlying system corruption or hardware problems cause the issues, upgrading won’t resolve them. Fix known problems before upgrading to prevent carrying corruption into the new installation.
