After uninstalling the CrashPlan app on Windows 7, the reference to the tray icon remains present in the notification area settings screen.

Before you begin

Make sure you have completely uninstalled CrashPlan.

Recommended solution

Removing the CrashPlan tray icon notification area setting requires you to shut down Windows Explorer (explorer.exe) and remove two registry keys. Windows will automatically recreate the tray cache after this.


  1. Create a .bat file by one of these methods:
    • Download clearnotificationicon.bat
    • Open a text editor such as Notepad, enter the commands below, and save it as a .bat file
taskkill /im explorer.exe /f

reg delete "HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify" /v IconStreams /f

reg delete "HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify" /v PastIconsStream /f

start "Shell Restarter" /d "%systemroot%" /i /normal explorer.exe
  1. Double-click the .bat file to run it
    Running the .bat file will shut down explorer.exe, remove the required registry entries, and then restart explorer.exe. After that, Windows will recreate the cache and CrashPlan will no longer appear in the system tray notification icon settings.
