Windows 10 Calculator Key

calculatorkeyboardwindows 10

My keyboard has a "calculator" key on it. In the registry at:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\18

I have ShellExecute set to C:\Program Files (x86)\SpeedCrunch\SpeedCrunch.exe.

While regedit is open focused, pressing the calculator key opens up SpeedCrunch, but at any other time the key opens up Windows 10's calculator app.

How can I set it to open SpeedCrunch at all times with my calculator key?

Try surrounding the path to SpeedCrunch in quotation marks ("):

  1. Create a new registration file with a text editor and save as keyboard_calc_to_speedcrunch.reg:

    Windows Registry Editor Version 5.00
    
    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\18]
    "ShellExecute"="\"C:\\Program Files (x86)\\SpeedCrunch\\speedcrunch.exe\""
    
  2. Import/merge keyboard_calc_to_speedcrunch.reg into the registry.

  3. Refresh Windows Explorer (using NirCmd): nircmd.exe shellrefresh

To restore the original behaviour, create and merge keyboard_calc_restore.reg:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\18]
"ShellExecute"=-
