Windows 7 How to build a .REG to optimize W7 ?

Hello,
After installing a fresh Windows 7, I would optimize it doing the steps of those guides:

Speed Up Windows 7 - Ultimate Guide To Make Windows 7 Blazing Fast!!! (17 steps)
Link Removed - Invalid URL (7 steps)

Instead of doing this manually, I would use a .REG (and/or .BAT) file.
So, for those steps below:

1. Disabling the Search Indexing Feature in Windows 7.
2. Disable the Aero Theme on Windows 7.
3. Disable all Visual Effects (Sys. Properties > Advanced > Performance > Settings > Visual Effects)
4. Disable the User account control (UAC).
5. Disable the Windows 7 Sidebar.
6. Disable the Aero Peek and Aero Snap features in Windows 7.
7. Change the Power Plan To Maximum Performance.
8. Disable the Thumbnail Preview Feature.
9. Disable all System Sounds (run > mmsys.cpl).

Question A.
What are the Windows 7 registry branches storing those settings?

Question B.
Which Windows 7 registry tool can help me to localize those branches?
Comparing the registry before and after manually doing one of those step.

7 is blazingly fast out of the box without touching anything!

I would suggest it would be a big mistake to have a single .reg file to perform all those functions in one sweep. You may find a use for one or two later, and it would be troublesome to try and return them one by one. Quite frankly, if you are about to destroy visual effects and sound, plus those other goodies, perhaps , without rudeness intended, you would be better off staying with XP or 2000?
However, there are various tune up program available, which you might find useful? I am sure some members can give you links to them in this thread.
