The Shift + Right Click shortcut reveals an expanded context menu with advanced options (e.g., "Open as Administrator," "Copy as Path") for taskbar apps. If it fails, you lose quick access to these tools, often due to Corrupted system files, Third-party apps, Outdated/corrupted context menu handlers, or Incorrect registry settings.
Press Ctrl + Shift + Esc to open Task Manager.
Find Windows Explorer under Processes.
Right-click it and select Restart.
Right-click the Taskbar → Taskbar settings → turn on Task Manager shortcut for quick access next time.
Open Command Prompt as Admin.
Run DISM /Online /Cleanup-Image /RestoreHealth.
After completion, run sfc /scannow.
Reboot your PC.
Run Commands Twice: If sfc /scannow shows errors, rerun it after a reboot to ensure all corruptions are resolved.
Open PowerShell (Win+I) as Terminal Admin.
Paste: Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
Press Enter and Reboot afterward.
Go to Settings → Windows Update.
Click Check for updates.
Install pending updates and restart.
Press Win + R, type regedit, and hit Enter.
Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions
Right-click the right pane → New → Key, and name it Blocked.
Do NOT add any entries; this resets blocked extensions.
Close Registry Editor and reboot.
Right-click the Shell Extensions key → Export to create a backup.
Press Win + R, type msconfig, and hit Enter.
Under Services, check Hide all Microsoft services → Disable all.
Go to Startup → Open Task Manager → disable all startup items.
Reboot and test the shortcut.
If it works, re-enable services/apps one by one to find the culprit.
Prioritize disabling services/apps installed around the time the issue began.
Go to Settings → Accounts → Family & other users.
Click Add account → create a new local/admin account.
Log in to the new account and test the shortcut.
Use Settings → Accounts → Sync your settings to check if synced configurations (e.g., themes, passwords) differ between accounts.
Go to Settings (Win+I) → System → Recovery.
Click Reset PC → choose Keep my files.
Follow on-screen instructions.
If Shift + Right Click still fails, try Ctrl + Shift + Click on the taskbar icon to launch apps as Administrator.
Avoid third-party taskbar customization tools.
These apps often conflict with native shortcuts and can override system behavior.
