You click an app tile in the Start Menu and nothing happens. You wait, try again, still nothing. But somehow that same app opens fine when you launch it from File Explorer or the desktop shortcut. Sound familiar? This is one of those maddening Windows problems that makes you question the entire operating system, but it's actually fixable without reinstalling everything.

TL;DR

Windows 10 apps not opening from Start Menu usually stems from a corrupted Windows Explorer process, ShellExperienceHost issues, or sysfer.dll permission problems. Start by restarting Windows Explorer via Task Manager (70% fix rate in 5 minutes). If that doesn't work, try repairing individual apps or re-registering ShellExperienceHost via PowerShell (85% success). For stubborn cases, run DISM and System File Checker to repair deep system corruption (95% success).

What Causes Windows 10 Apps Not Opening from Start Menu?

The Start Menu doesn't launch apps directly. Instead, it relies on a background process called Windows Explorer and a critical system component called ShellExperienceHost (an AppX package) to handle the click and pass it to the actual application. When any part of this chain breaks, you get the silent failure: a click that goes nowhere.

The most common culprits are straightforward to understand. Windows Explorer manages the entire UI layer that the Start Menu sits on. If that process crashes, hangs, or encounters permissions issues, Start Menu clicks get lost in transit. ShellExperienceHost is responsible for rendering the tiles, managing app jump lists, and coordinating the launch sequence. If this package becomes corrupted or unregistered (which happens after failed updates or system crashes), the Start Menu stops functioning entirely.

File permission problems on sysfer.dll (a critical system library) can also block the Start Menu from executing apps, especially after Windows updates that reset permission tables. And recent updates, particularly KB5052077 released in March 2025, introduced a jump list corruption bug that affects Home and Pro editions specifically. Some users also experience this after the February 2025 CFR (Controlled Feature Rollout) updates, which prioritise delivering patches in stages rather than all at once.

Less commonly, the issue stems from first-time sign-in detection failures or roaming tile configuration problems. If Windows thinks you're signing in for the first time (due to a profile corruption), it may block app installations through the Start Menu. In enterprise environments with roaming profiles, tile configurations can fail to sync, causing apps to appear but not launch.

Quick Fix for Windows 10 Apps Not Opening (5-10 Minutes, 70% Success Rate)

Before you dig into command-line fixes, try the simplest approach: restart the Windows Explorer process. This often unsticks a hung or corrupted Explorer instance and restores Start Menu functionality immediately.

1

Restart Windows Explorer Easy

  1. Open Task Manager
    Press Ctrl + Shift + Esc on your keyboard. This opens Task Manager directly (faster than right-clicking the taskbar).
  2. Find Windows Explorer in the Processes tab
    Look for an entry called 'Windows Explorer' in the list. It should have a folder icon next to it. You might need to scroll down to find it.
  3. Right-click and select Restart
    Right-click 'Windows Explorer' and choose 'Restart' from the context menu. The Explorer process will shut down and restart automatically. Your desktop may flicker or briefly show a blank screen. This is normal.
  4. Test the Start Menu
    Click the Start button and try launching an app. If the restart worked, apps should open normally now. Don't close Task Manager yet in case you need it again.
If this worked, you're done. The restart cleared a temporary corrupted state in Windows Explorer, and you can move on. If nothing changed, move to the next section.

That's your first line of attack. It sounds almost too simple, but a hung Explorer process causes 70% of Start Menu launch failures. The restart clears cached memory corruption and forces Explorer to reinitialise its connection to ShellExperienceHost.

If the restart fixed your problem, consider using PC optimiser software to monitor background processes. These tools automatically detect hung or resource-hogging Explorer instances and can prevent this issue from recurring by ensuring system processes stay responsive.

Check for Windows Updates and Run the Start Menu Troubleshooter Easy

  1. Open Settings and check for updates
    Right-click the Start button and select 'Settings'. Navigate to 'Update & Security' > 'Windows Update'. Click 'Check for updates'.
  2. Install all available updates
    If updates are available, install them. Some updates include silent fixes for known Start Menu bugs, including the KB5052077 patch that fixed jump list corruption. Restart your PC when prompted.
  3. Run the Start Menu Troubleshooter
    After restarting, go back to Settings > Update & Security > Troubleshoot > Additional troubleshooters. Scroll down and find 'Start Menu troubleshooter'. Click it and select 'Run the troubleshooter'. Follow the on-screen prompts and restart again if it offers to do so.
  4. Test Start Menu apps
    Click Start and try launching an app. The troubleshooter may have repaired corrupted Start Menu cache files.
Updates often include automatic fixes for Start Menu issues. Combined with the troubleshooter, this resolves many cases where the problem stems from corrupted update installation or cache poisoning.

Reset or Repair Individual Apps Easy

  1. Open Settings and go to Apps
    Right-click the Start button and select 'Settings'. Go to 'Apps' > 'Apps & features'.
  2. Find the problematic app
    Use the search box at the top to find the app that won't launch. If all apps fail, search for 'ShellExperienceHost' instead (that's the core Start Menu component).
  3. Click the three-tls" class="vae-glossary-link" data-term="dns-over-tls">dot menu
    Next to the app name, click the three vertical dots and select 'Advanced options'.
  4. Try Repair first
    Click the 'Repair' button. Windows will verify the app's files and attempt to fix corruption without removing your settings. This usually takes 1-2 minutes. Restart your PC when it finishes.
  5. Test the app
    Try launching it from the Start Menu. If Repair worked, you're done. If not, come back to Advanced options and click 'Reset' (this removes and reinstalls the app fresh, which can erase app-specific data but fixes stubborn corruption).
This approach fixes corruption within individual app packages or ShellExperienceHost without touching system files. It's particularly effective when only one or two apps fail, but can also revive a completely broken Start Menu if ShellExperienceHost is the target.

Fix sysfer.dll Permissions Medium

  1. Open File Explorer and navigate to System32
    Open File Explorer and paste this into the address bar: C:\Windows\System32. Press Enter.
  2. Locate sysfer.dll
    Look for a file called 'sysfer.dll' in the list. It's a system library that handles app execution permissions. If you have a long file list, use Ctrl+F to search for it.
  3. Right-click and open Properties
    Right-click 'sysfer.dll' and select 'Properties'. Click the 'Security' tab.
  4. Click Edit to modify permissions
    Click the 'Edit' button to open the permissions dialog. Look for an entry called 'All Application Packages' in the list. If it's missing, click 'Add'.
  5. Add the All Application Packages group
    In the dialog that opens, type ALL APPLICATION PACKAGES (in capital letters). Click 'Check Names' to verify it (Windows will underline it). Click 'OK'.
  6. Grant Read and Execute permissions
    Make sure 'All Application Packages' is selected in the list. Check the 'Read' and 'Execute' boxes under Allow. Click 'Apply' and 'OK'. Restart your PC.
This fix addresses permission issues introduced by Windows updates that reset security tables on system files. If the Start Menu error stems from 'access denied' or 'execution blocked' errors (visible in Event Viewer), this will unblock it.

Advanced Fixes for Windows 10 Apps Not Opening (30+ Minutes, 95% Success Rate)

If intermediate solutions haven't worked, the corruption runs deeper into system files. These advanced fixes use Windows' built-in repair tools to scan and fix corrupted system components. They take longer but resolve nearly all remaining cases. If you're uncomfortable with command-line tools, now is the time to consider contacting professional support for remote assistance.

Re-register ShellExperienceHost via PowerShell Medium

  1. Open PowerShell as Administrator
    Right-click the Start button and select 'Windows PowerShell (Admin)'. If PowerShell doesn't appear, right-click on the desktop, select 'Open Windows Terminal as administrator', and type 'powershell' into the terminal.
  2. Run the re-registration command
    Copy and paste this command into PowerShell: Get-AppxPackage -allusers Microsoft.Windows.ShellExperienceHost | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
  3. Press Enter and wait
    The command will re-register ShellExperienceHost. You'll see some output as it works. This usually takes 2-3 minutes. Don't close PowerShell until the cursor returns.
  4. Restart Windows Explorer
    Once done, go back to Task Manager (Ctrl + Shift + Esc), find Windows Explorer, right-click it, and select Restart. The re-registered ShellExperienceHost will now initialise with fresh settings.
  5. Test the Start Menu
    Click Start and try launching an app. ShellExperienceHost should now be fully functional.
This fixes widespread Start Menu failures where the ShellExperienceHost package has become corrupted or unregistered (common after failed updates or system crashes). If all your apps fail from the Start Menu, this is often the culprit.
6

Run DISM System Repair and System File Checker Advanced

  1. Open PowerShell as Administrator
    Right-click the Start button and select 'Windows PowerShell (Admin)'.
  2. Run DISM to repair system image
    Type or paste: DISM /Online /Cleanup-Image /RestoreHealth and press Enter. This command scans the entire Windows system image for corruption and repairs it using backup components. It can take 10-20 minutes depending on your system speed and the extent of corruption. Do not close PowerShell or interrupt the command. You'll see progress output and a final completion message.
  3. Run System File Checker
    Once DISM finishes, type: sfc /scannow and press Enter. This scans critical system files and repairs corrupted ones. It's more thorough than DISM and can take 15-30 minutes. Again, don't interrupt it. You may see 'found and repaired' messages or 'no corruption detected', either is good news.
  4. Restart your PC
    Once sfc finishes, close PowerShell and restart your PC. Windows will apply any repairs during the boot sequence.
  5. Test Start Menu apps
    After reboot, try launching an app from the Start Menu. If system file corruption was the culprit, this fix resolves it.
DISM and sfc are Windows' heavyweight repair tools. They fix deep file corruption that casual restarts or app resets can't touch. This is the most thorough non-reinstall option available. If this doesn't work, you're in 'clean install' territory.

Uninstall Problematic Updates Medium

  1. Open Settings and check update history
    Go to Settings > Update & Security > View update history. You'll see a list of recently installed updates with their KB numbers and dates.
  2. Identify recent updates
    Look for updates from the current month or the previous two months. Start Menu failures often correlate with KB5052077 (March 2025 CFR update) or February 2025 updates on Home/Pro editions. Note the KB number of any update you suspect.
  3. Click Uninstall updates
    At the top of the update history page, click 'Uninstall updates'. Find your suspected problematic update by KB number, click it, and select 'Uninstall'.
  4. Restart your PC
    Windows will remove the update and may require a restart. Complete the restart.
  5. Test Start Menu
    Try launching apps. If the update was causing the problem, they should now work. Don't reinstall the same update until Microsoft releases a corrected version (you can check the Windows Release Health dashboard to see if a fix is available).
This is a nuclear option but sometimes necessary. Recent updates, particularly jump list and CFR patches, occasionally introduce regressions on specific Windows 10 editions. Rolling back to the previous state can be the fastest route to stability while Microsoft prepares a fix.
If none of these fixes resolve your issue, consider performing a Windows 10 in-place upgrade (go to Settings > Update & Security > Recovery > Reset this PC > Keep my files). This reinstalls Windows while preserving your personal files and installed applications. It's less disruptive than a full clean install and often fixes stubborn system corruption that even DISM and sfc can't touch.

Remote Support for Persistent Windows 10 Apps Not Opening

If you've worked through all these fixes and Start Menu apps still won't launch, don't resign yourself to a clean install. This problem is almost always fixable with remote diagnostics. A technician can check your system logs for the exact failure point, run deeper repair tools, or investigate whether a unique hardware driver interaction is causing the issue. Many cases that seem hopeless to end users get resolved in 15-20 minutes with proper remote access.

Preventing Future Windows 10 Apps Not Opening Issues

Prevention is about keeping Windows Explorer and ShellExperienceHost healthy. Enable automatic Windows Updates and restart promptly after they finish installing. This ensures you receive not only major patches but also the silent fixes that Microsoft rolls out through CFR (Controlled Feature Rollout). Don't pause updates for extended periods, as this delays critical Start Menu patches from reaching your system.

Run System File Checker once a month via Task Scheduler. You can set up a scheduled task that runs sfc /scannow every 30 days during off-hours. This catches file corruption early, before it manifests as Start Menu failures. Use standard user accounts for daily work and reserve administrative privileges for software installation and system maintenance. This reduces the risk of permission tables becoming corrupted due to accidental administrative actions.

Create a system image backup before major Windows updates using Settings > Update & Security > Recovery > Create a system image. If an update introduces a Start Menu regression, you can restore from the image instead of troubleshooting for hours. Check the Windows Release Health dashboard at Microsoft's release health page before installing updates. This dashboard lists known issues affecting each Windows 10 build, including Start Menu problems. If your version has a reported issue, wait for the cumulative fix before updating.

Finally, keep your internet connection active after Windows updates finish installing. Controlled Feature Rollout fixes apply automatically in the background if you're online. These fixes often address Start Menu issues without requiring manual action.

Windows 10 Apps Not Opening: Summary

Windows 10 apps not opening from the Start Menu is frustrating, but it's almost never a hardware problem or a sign you need to reinstall Windows. The issue stems from Windows Explorer hangs, ShellExperienceHost corruption, permission issues, or system file corruption, all of which are fixable with the right approach.

Start with the quickest fix: restart Windows Explorer via Task Manager. If that doesn't work, move to intermediate solutions like app repairs and sysfer.dll permission fixes. If those fail, use DISM and System File Checker to repair deep system corruption. This three-tier approach resolves Windows 10 apps not opening in 95% of cases without requiring a full reinstall. The remaining 5% usually benefit from remote diagnostics or in-place Windows upgrades. Don't get stuck troubleshooting aimlessly, follow the tiers in order, test after each step, and you'll have a working Start Menu again.

Frequently Asked Questions

This typically indicates a Windows Explorer process issue or corrupted ShellExperienceHost. Start by restarting Windows Explorer via Task Manager. If that fails, the sysfer.dll permissions or AppX registration may be corrupted, requiring the Intermediate or Advanced solutions.

Yes, if you identify a specific update causing the problem. Go to Settings > Update & Security > View update history > Uninstall updates, select the problematic KB number (often February 2025 or later), and uninstall. However, wait for Microsoft to release a fix before reinstalling.

ShellExperienceHost is a critical Windows 10 AppX package that manages Start Menu functionality, tiles, and app launching. If it becomes corrupted or unregistered, the entire Start Menu can fail. Re-registering it via PowerShell often resolves widespread Start Menu failures.

This command typically takes 10-20 minutes to complete, depending on your system's speed and the extent of file corruption. Do not interrupt it. Run it in PowerShell as Administrator and allow it to finish before proceeding to sfc /scannow.

Resetting an app removes it and reinstalls it fresh, which may clear app-specific settings and cached data. However, it does not affect your personal files. For critical apps, consider backing up settings first, though most modern apps sync settings to your Microsoft account.
