Something I made real quick when I got my windows 7. My first theme just using megaupload for now(if there's big enough demand ill just upload it to piratebay).

Unrar all of this into your profile folder.(c/users/>yourcomputername<)
Screensaver needs to be put in your windows folder where you have windows 7 installed(or your computer won't see it).
right click your desktop click personalization change to the neotokyo theme(browse for it)
make sure the screensaver works.
Go to sounds make sure your sound scheme is neotokyo.
If it isn't, scroll down to windows logon click browse choose login.wav test it to make sure.
Do the same for logoff only use logon.wav do the same thing for exit windows.
Then click save as and name it neotokyo.
If the link dies tell me I will reupload it
