Add Radio Bar

To listen to your favorite radio stations on the net, and have a list of the last 6 stations you visited, you can enable the Radio toolbar. To do so, you must have the latest Windows Media Player installed (at least version 6.01). To add the Toolbar:

From the Internet Explorer menu, select Tools > Internet Options > Advanced tab
Under the Multimedia heading, put a checkmark in the box for Always show Internet Explorer Radio bar
Right-click on the Internet Explorer toolbar, and click Radio

You can choose radio stations from the Radio Station Guide, and Internet Explorer will show the last 6 radio stations you have listened to under the Radio Stations button.

If you want to delete this list, you have to do this from the registry. Here's how:

Start the Registry Editor
Go to HKEY_CURRENT_USER \ Software \ Microsoft \ MediaPlayer \Radio \ MRUList
Delete the Radio_Station_x entries (x will be a number)
Modify Radio_Station_Count to 0

If you want to delete just one or more individual stations, you can delete only certain stations if you wish:

Delete the unwanted Radio_Station_x entries
Rename the x value of the remaining to go in numerical order
Modify Radio_Station_Count to match the number of stations

To see to which station a particular Radio_Station_x entry belongs, just double click on the Radio_Station_x entry and you can see the stations URL and name displayed on the right side of the Binary Value.

You can increase the Buffer size used by the Radio Bar to improve playback performance:

Select Start > Programs > Accessories > Entertainment, and then click Windows Media Player
On the View menu, click Options
On the Advanced tab, click Streaming Media (Windows Media), and then click Change
Increase the buffer size to any number up to 30 seconds
