I want to replace the default Windows 10 calculator with CalcTape.exe in the registry. How?
Solution 1
One method that isn't too invasive and can easily be undone is to use the Image File Execution Options Debugger key. This is the same method employed by Process Explorer when you replace Task Manager.
If you typically run calc
or calc.exe
to launch the Calculator this will work:
- Launch Regedit
- Navigate to :
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options
- Create a new reg
key
calledcalc.exe
underHKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options
. - Create a new
string
value calledDebugger
. - The
data
value can then be the path to your custom exe.
A reg file export of such an update would look like the following if this is simpler to follow:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image
File Execution Options\Calc.exe]
"Debugger"="C:\\temp\\test.exe"
This will work for the above scenario but then there are a number of ways to launch an application and this will not cover all of them.
Solution 2
The top answer will change the app that's launched with the calc
command, but the calculator key may still need further configuration:
To change the app that's launched when you press the calculator key, change the following registry value:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\18
Set ShellExecute
to the path you want, for example: C:\Program Files\CalcTape.exe
.
Alternatively, you can set up a macro: AutoHotkey: how to assign a command to the "Calc" key?

LPChip over 5 yearsTo my knowledge, there is not a program or button that will launch the windows calculator, so setting your shortcuts right should be all you need to do. Occasionally there are keyboards that have a calculator button, these often just call calc.exe. If you rename calctape.exe to calc.exe and set it first in your path environmental setting, it should work there too.

Ramhound over 5 years@LPChip - Microsoft used to sell Keyboards that would launch specific programs, but Windows 10 only has the UWP calculator application, so renaming the executable isn’t a viable solution
