Disassociate file with cmd.exe

Question

I recently chose cmd.exe as a default program for .jar files with instant regret.

How do I associate this back again with javaw.exe in the JRE? The default program check box is disabled, so selecting it again doesn't warrant a long term result.

I am using Windows 7. I'd appreciate your suggestions.

Answer 1

Get Default Programs Editor

1. Start the program and click 'File Type settings'
2. Click 'Context Menu'
3. Select .jar from the list
4. On the context menu page, select 'Open' or whatever the default is. You can either delete it and add a new item called "open", or just click Edit
5. On the item page (either by adding or editing an item) browse to javaw.exe. It's in C:\Program Files (x86)\Java\jre6\bin (or, if you're running 32bit, without the "(x86)" part.
6. Make sure the parameters look like this: "C:\Program Files (x86)\Java\jre6\bin\javaw.exe" -jar "%1" %*
7. Then save it, of course.
