That was fun now, wasn't it….
You have your "Registry", and your disk space (on your "C:" drive).
Removing something from the registry (entries for a program) doesn't remove the folders and files on the C: drive the program uses.
To reclaim (or recycle) the disk space, you have to remove the folders on the C: drive.
The registry grows and shrinks as needed. Besides removing unnecessary entries, there's not much you can do about it's size.
I hope that answers your question.

You're talking about two totally different "spaces" here.say in add/remove programs a file says it takes up 9mb for example, so when you delete something out the registry, does that sort of recycle the space like a recycle bin? So you aren't losing memory?
