360 users seem quite fond of the new-look Dashboard, but one major gripe on the forums points to the prominence given to adverts, and in particular how they take priority over the games and content.
Searching for a solution, the proactive users on Reddit have taken matters into their own hands and blocked 'rad.msn.com', the server Microsoft uses to beam ads to the 360.

- Sign up for a free OpenDNS account.
- Add a network for your current IP address.
- Go to Advanced Settings and next to 'Domain Typos', check the box 'Enable typo correction' if it's not already checked and apply.
- Go to Web Content Filtering settings and set the filtering level to 'None', and under 'Manage individual domains', put rad.msn.com and select 'Always block' and then click 'Add domain'. Screenshot.
- On your Xbox, go to System Settings -> Network Settings -> (your connection) -> Configure Network -> DNS settings -> Manual, and enter the OpenDNS IP addresses for the primary and secondary DNS servers: 208.67.222.222 and 208.67.220.220.
- You may need to clear your hard drive cache before ads disappear entirely: System Settings -> Storage -> Hard Drive -> press Y -> Clear System Cache (note that you'll have to re-download any title updates for any games you play after doing this).
