Not to resurrect a dead thread, but this is somewhat important I felt

To get the 360 SDK software to work, follow the same instructions but with two small changes. Blatant copy/past as follows (thanks Carch for your instructions, it helped me get this going

):
1. Install the shell extensions as you normally would.
2. Create a new shortcut on your desktop.
3. For the target location enter
CODE
%windir%\syswow64\explorer.exe ::{57B2D0D9-32DD-476a-B663-C85D2EA24AA5}, /separate
4. Give it the name 'Xbox Neighborhood'
5. To setup the correct icon, hit the change icon button and point it at
CODE
%windir%\syswow64\xeshlext.dll
6. Select the icon which has the word 'xbox' readable on it.
7. Click OK and all is done.
