Microsoft has just released the Release Candidate of Media Player 9, available as a 10Mb download from windowsmedia.com. For installation on Windows XP it's a good idea to turn on System Restore, just in case you run into problems. For the record, I've installed it on two systems without a hitch.
A new feature of this version is the new Media Player toolbar (see screenshot below) that sits in your taskbar. Tres cool.
Words of the day: Absolute harmony.
