Greenshot is a popular lightweight screenshot tool used for capturing, annotating, and saving screenshots quickly. On Windows 11, some users experience issues where Greenshot does not launch, screenshots are not captured, hotkeys stop working, the editor does not open, or the app runs but does nothing.
These problems usually occur due to startup issues, keyboard shortcut conflicts, permission restrictions, outdated versions, or Windows 11 background app behavior, not because Greenshot is incompatible with Windows 11. The steps below will help you fix the issue step by step.
How to Fix Greenshot Not Working in Windows 11
Follow the steps below in order. After each step, test Greenshot again before moving on to the next solution.
1. Make Sure Greenshot Is Actually Running
Greenshot runs in the background and may not open a visible window.
- Click the up arrow in the system tray
- Look for the Greenshot icon
- If the icon is missing, search for Greenshot in the Start menu
- Launch the app manually
If Greenshot is not running, hotkeys will not work.
2. Restart Greenshot and Windows Explorer
Temporary glitches can prevent screenshot tools from working.
- Press Ctrl + Shift + Esc to open Task Manager
- End any Greenshot.exe processes
- Right-click Windows Explorer
- Select Restart
- Launch Greenshot again
This refreshes system tray and keyboard hook services.
3. Run Greenshot as Administrator
Permission issues can block screen capture or file saving.
- Right-click the Greenshot shortcut
- Select Run as administrator
- Try taking a screenshot again
- If it works, open Properties > Compatibility
- Enable Run this program as an administrator
This ensures Greenshot has the required access.
4. Check and Fix Hotkey Conflicts
Windows 11 and other apps may override Greenshot shortcuts.
- Right-click the Greenshot tray icon
- Open Preferences
- Go to the Keyboard tab
- Check screenshot hotkeys (Print Screen, Alt + Print Screen)
- Change hotkeys if they conflict with other apps
Windows Snipping Tool often takes over the Print Screen key.
5. Disable Windows Snipping Tool Print Screen Shortcut
Windows 11 may redirect Print Screen to Snipping Tool.
- Open Settings > Accessibility > Keyboard
- Find Use the Print screen key to open Snipping Tool
- Turn this option OFF
- Restart Greenshot and test again
This restores Print Screen control to Greenshot.
6. Update Greenshot to the Latest Version
Older versions may not work properly on Windows 11.
- Open Greenshot
- Go to Help > Check for updates
- Install the latest version if available
- Restart your PC
Updates often fix compatibility and hotkey issues.
7. Check Antivirus or Security Software
Security software may block screenshot tools.
- Temporarily disable third-party antivirus
- Try using Greenshot
- If it works, add Greenshot to the exclusion list
- Re-enable antivirus protection
Do not leave security software permanently disabled.
8. Enable Greenshot Startup Option
If Greenshot stops working after reboot, it may not start automatically.
- Right-click the Greenshot tray icon
- Open Preferences
- Enable Launch Greenshot on startup
- Restart your PC
This ensures Greenshot is always ready to capture screenshots.
9. Reinstall Greenshot Completely
Corrupted files can prevent Greenshot from working.
- Uninstall Greenshot from Settings > Apps > Installed apps
- Restart your PC
- Download the latest Greenshot installer from the official website
- Install Greenshot and launch it
- Configure hotkeys again
This removes corrupted configuration files.
10. Test Greenshot in a New Windows User Account
User profile corruption can block background apps.
- Create a new Windows user account
- Sign in to the new account
- Install and run Greenshot
- Test screenshot functionality
If it works, the original profile may be corrupted.
Final Thoughts
Greenshot not working in Windows 11 is usually caused by hotkey conflicts, Windows Snipping Tool settings, permission issues, or outdated versions, not by Windows 11 itself. In most cases, disabling the Snipping Tool Print Screen shortcut, updating Greenshot, or fixing hotkey assignments resolves the issue quickly.
Keeping Greenshot updated and avoiding multiple screenshot tools running at the same time helps ensure stable performance.
