This is my first post, yay!
I was playing around with Personalization Center today, and ended up making a theme using 12 wallpapers I happened to have and some sound effects, which I also happened to have. Anyway, I rather liked the end result...and thought maybe you might also.
Making Windows 7 themes is as easy as slicing bread, so I can't say that I had to particularly work hard on this theme. I wasn't even planning on sharing it. But then I thought, why not...what is there to lose?
I have uploaded the themepack (which is a .themepack file) inside a compressed zip folder. Don't worry it's not a virus....but I'd always suggest scanning ANY file before extracting the contents to your computer.
Once extracted simply double click on the "Cars.themepack" file and it will automatically extract and open the contents in the Microsoft Windows Personalization Center, and then set it as your new Windows 7 theme.
Sound effects are included...I have tried to replace as many Windows sounds as possible, whilst at the same time trying to make the sound fit the function it's "sounding" for, if you get me (sorry! Bad english!). Anyway, my personal favourite is the sound that you hear when you empty your recycle bin! But maybe that's just me.
There are 12 high quality backgrounds of some spectacular cars included in the theme, set by default to auto change every 20 minutes. However, you can easily change this if you wish to do so. Screenshot (from my PC desktop): Download the theme from MediaFire:
