So I thought I'd just put together this little tutorial on how to do it!
1. First of all, go to http://www.neowin.net and register! A lot of their downloads are forum based and you need to be a member first!
2. Navigate to http://www.neowin.net/forum/index.php?showtopic=308905 and download UXTheme_Multi_patcher and run it. This program will replace the Microsoft version on your system and will allow other themes to run other than the blue, olive or silver Lunas.
IMPORTANT...you must wait a minute for the patch program to patch the file! Otherwise Windows File Protection will replace it with the original!
3. Next, go through the forum http://www.neowin.net/forum/index.php?showforum=36 and check out some of the Visual Styles posted there. I liked the Windows Media Player 11 version and downloaded it - it takes you to DeviantArt web site where you download it and others.
4. Unzip the downloaded files and folders into c:\windows\resources\themes
5. Go into the folder and find the .msstyles file and double click it. This will open the Display dialog box from where you can apply the style.
Another one called NGX
6. To get Vista style drives, go to: http://www.megashare.com/66876 and unzip them to a folder and put that folder in the Windows folder. Then run the program in there.
7. Go to here http://www.deviantart.com/deviation/47056403 and download the Vista pack. After they're installed, go to Control Panel >Mouse>Pointers and choose the Windows Aero scheme. You can then also set your Sound scheme too!
8. You may also want to try LClock which is a customizable clock. http://www.neowin.net/forum/index.php?showtopic=157465
Hope this helps. It's a lot of fun and nice to get the system looking the way you want!
I left off the Sidebar. I have it for download for anyone who wants to be bothered with it!
Oh and if you have Windows Blinds/StyleXP, you might look at why this way is easier on your machine....
