You can download said theme from various sources on the internet.
Here’s a preview of the voices.
You can grab a copy of the theme from here.
Also I recommend turning the “Chin~” sound off as it does get annoying after a while.

Update: Windows 7-tan Nanami Madobe Theme
Official Windows 7-tan Wallpapers
For those who are not in the loop, Microsoft has adoped an official OS-tan – Nanami Madobe, apparently the first 7777 copies of Windows 7 Ultimate released in Japan will have a special theme featuring wallpapers, a colour scheme and voice pack voiced by Nana Mizuki.
The high resolution wallpapers presented here for your enjoyment were supposedly leaked online.
It could be a genuine leak or a clever marketing scheme to capture the interest of Otaku everywhere, either way it’s still win-win for us ain’t it?
