scmartindale Posted April 21, 2008 Share Posted April 21, 2008 How do you change the default calculator in Windows XP?I have installed SpeedCrunch (a popular calculator amongst KDE and Qt users) and I want to make it show when I hit the really convenient Calculator Key on my Microsoft keyboard.

Camarade_Tux Posted April 21, 2008 Share Posted April 21, 2008 Find and replace calc.exe. It's most straightforward way.Don't forget to backup calc.exe first.(if the original calc.exe doesn't want to go away, it is likely to be protected by windows' sfc but I doubt it is) Link to comment Share on other sites More sharing options...
scmartindale Posted April 21, 2008 Author Share Posted April 21, 2008 I solved my own problem by searching the registry for "calc.exe". Here's a convenient .reg hack that does it for you:Windows Registry Editor Version 5.00[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\18]"ShellExecute"="\"C:\\Program Files\\SpeedCrunch\\speedcrunch.exe\""(Actually, this just changes the mapping of the keyboard key. I don't think Windows has a default calculator.)Use_SpeedCrunch_as_the_calculator.reg Link to comment Share on other sites More sharing options...
