Hmm....
When it comes to my PC I personalize everything, and I mean EVERYTHING!
From wallpapers, to visual screens, icons, sound events, pointers, colours, I'm a maniac!
And I'm using the old Windows style, cause I don't like the modern one.
I change them about every two weeks...
I also have a few in my quicklaunch (yes , I am still using a quick launch!) and I am not ashamed to say I still have 1024x768 resolution.
(And if something it's not on my desktop, good luck to whoever is trying to find it in my PC! It's a jungle in here for whoever tries!)
