PC Essentials?

[n00bikscube]

I want to know the best way to visually customize and optimize my PC.
If you have any 'essentials' for PC please say so.
Also, I don't want rain meter.

Thanks.

Well, the more visual effects you have the slower your PC will be.
Hyperdesk is a really god customizing tool that doesn't eat your CPU/RAM.
