ViOrb Beta 2.4
A start button replacement for Windows XP
ViOrb automaticly replaces your start button with one that looks the same as Vista’s start orb. So you can get the Vista feel and look for Windows XP. Just download ViOrb, extract the ViOrb OneStep executable and then double click it.
ViOrb by default comes with a Vista skin but it can support 3rd party skins available on deviantart.
