XP & Vista: Add Calculator to Right-Click of My Computer
October 5th, 2007

If you have the My Computer (or Computer if you are running Vista) icon on your desktop, you can add the Calculator to the context (Right-Click) menu for much easier access. You can do this by creating a simple reg file and merging it to the Windows registry, here’s how:
- Open up Notepad (or right-click the desktop, mouseover New and select Text Document).
- Select and copy the following:Windows Registry Editor Version 5.00
- Paste it into the new text file.
- Save the text file and rename it to for example, XP_Calculator_MyComputer_Context.reg.It should look like this:
 - Right-click the newly created reg file and select Merge. A prompt will appear verifying that you want to add the information from the reg file to the registry, click Yes.

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\
CLSID\{20D04FE0-3AEA-1069-A2D8-08002B30309D}\shell\Calculator]
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\
{20D04FE0-3AEA-1069-A2D8-08002B30309D}\shell\Calculator\command]
@=”calc.exe”

Didn’t work for me in Vista. A desktop shortcut would work just as well, I suppose.

@geneio Nice catch. I had tried it on XP and Windows Server 2008. Since it worked on 2008, I made the rather poor assumption that it would also work on Vista. I’ll get back to the drawing board to find a Vista solution.

Why not just put a shortcut in the quick launch bar. It is available from any window.
