How to disable calculator in windows?

Question

I have a key on my keyboard that brings it up, and I hit all of the time accidentally.

It's a proprietary Logitech Calculator key, and their own program doesn't let you remap it.

This seems to be a hard problem that many people are failing at solving - the google results were awful. Apparently if you munge the EXE file windows will just fix it against your will.

Solution

The answer is Applocker.

1. Start=>Run=>secpol.msc
2. Security Settings=>Application Control Policies=>Applocker
3. Add new rule (type=path) to deny everyone %SYSTEM32%\calc.exe
4. Make sure to let it create the default rules it "wants" to create when you do this.
