Check my previous most, I wrote how you can show the current song being played on Windows Media Player as your latest status message on Google Talk (GTalk).
Some of the visitors complained and wrote to me that this feature was not available in their Windows Media Player. The possible problem is that Google Talk (GTalk) is installed the wrong way.
To fix this problem, you’ll have to reinstall by running the set up file as an administrator.
This will solve the problem and the Google Talk Plugin will be available in Windows Media Player on Windows Vista.
