Microsoft has unveiled three new "Extras" add-ons for Windows Vista Ultimate users, the first time new content has been provided in 5 months.

"Extras" were once angled as one of the main selling points for consumer to cough up extra for the "Ultimate" edition version of the operating system, but are now considered farcical by many as so few have been delivered.

The three new add-ons are a puzzle game, a sound scheme and additions to a video-based screen saver.

Microsoft Tinker is a casual game that "provides players with short puzzle game play sessions set in a warm, calming environment".

The sound scheme contains audio from Tinker while there's also the DremeScene content pack that adds three additional nature-setting Windows DreamScenes for the DreamScape screensaver.
