Hi there.
I recently decided to replace my XP laptops Explorer with the Xfce desktop environment, bbClean (a modification of BlackBox for Windows). I did it because I need my laptop to start up quick, and save on memory usage. I've been a fan of Xfce for a while now, my other laptop has Xubuntu installed. I also like minimalistic designs. So far I've been very impressed with it - its really doing the job very well! I even installed Rocketdock and Rainmeter with it to enhance the desktop controls, which work really nice with it.
Heres a picture:
What I would like to know is - What do you guys use, if anything, to modify your Windows UI?
Thanks,
