This is easy, just click on the start button and then on run. Once run is open, type in regedit and click OK.

Once you have regedit open, it is fairly easy to get where you want to.
Now you see the "folders" HKEY_CLASSES_ROOT, HKEY_CURRENT_USER, HKEY_LOCAL_MACHINE, HKEY_USERS, and HKEY_CURRENT_CONFIG
First lets get some basic terminology down.
These five main "folders" are calles hives, and their subfolders are called keys.
Click on the + next to HKEY_CURRENT_USER to expand the hive.
