Regshot is a small, free and open-source registry compare utility that allows you to quickly take a snapshot of your registry and then compare it with a second one - done after doing system changes or installing a new software product. The changes report can be produced in text or HTML format and contains a list of all modifications that have taken place between the two snapshots. In addition, you can also specify folders (with subfolders) to be scanned for changes as well.

I use Regshot. The ONLY problem I have with it, is that it works too well.
It records ALL changes, even things like moving the mouse cursor, or when a program silently checks for updates.
So after you do the compare, it's sometimes hard to find ONLY the changes you want to find. :)

I haven't tried it yet, but I wonder if it wouldn't work better after a "clean boot".

I use Regcool for registry editor. I have looked for it and I have not found anything better.

You can use File Compare or fc.exe to compare two registry export files, and thus monitor Windows Registry changes.

To use this File Compare or fc.exe program, first, export a .reg file, & name it as say rega.

After the change takes place, export the changed .reg file & name it as say, regb.

Now, open a command prompt and type:

Code:
fc /u rega.reg regb.reg > regcompare.txt

Since .reg files use Unicode, the /u switch, tells fc.exe to use Unicode.

You can now inspect the output regcompare in Notepad.
