Edit the Registry. The Registry contains two basic elements: keys and values. If you know the key you want to edit, press Control+f to open the Find dialog box. The Registry is a system database where Windows operating system and other software keep their settings. Registry Editor is a program that edits that database. This is how you start it.

I'm trying to programmatically check file associations by the file extension (for example .jnlp files). I keep reading that
is the Registry key to check. However, if you change the association through Windows Explorer:
Open With > Choose Program > (Always use the selected program)
the change isn't at all reflected in this Registry key. Where else is this information stored?

Take a look in:
and the sub-key of that is the extension you reassigned. Under that there will be the UserChoice and OpenWithList sub-keys which will contain your redefinition.
You may also want to read http://support.microsoft.com/kb/950505 which talks about your issue.
This is a two-part look-up.
First, you look up the default value of HKEY_CLASSES_ROOT[file_extension]. For your extensions, .jnlp, the value is 'JNLPFile'. Let's call this the [file_descriptor].

I have a hard drive plugged into my computer here which I'd like to edit the registry for. When opening up 'regedit,' it obviously loads the local Windows registry. Is there a way to load the Windows registry for, say, drive G? Is there a certain file I need to open to edit this other installation's registry?

I have only done it a few times.
It is a very strange operation to drop in a hive into the registry and edit it, using the quick method, but it worked.
You select HKLM in your current registry, and then the File/Load Hive operation will become usable.
File means you have to find the registry hive file itself by browsing. WindowsSystem32config
Load in and name this 'other' hive section which will look like it has become part of your current registry. Use a really obvious and different name, so you can find it.
The strange thing was why I would want to view this all mixed into my current registry, but thats what they said to do ?? There must be a better way to clear the slate and load in ONLY the one hive I want to edit, but it worked, so I rolled with it. I had a full backup, so that helped when presented with this odd method.
Whatever you do certannly do not Import it in, that would be a mess.
Make your changes, which should change it immediatly, Then unload the hive File/Unload Hive and then close. Selecting unload hive unloads the one you loaded (there are no options then).

Any changes you ant to make for the other installation you may need to go to (C:UsersHimanshuAppDataRoaming) where 'C' is the drive of windows installation and you need to find this file 'hkey_local_machine.reg' . When you have got the file make any changes you want to and then load this file into the machine of which the file was taken from.
