Cause: Windows XP tries to guess what you want to do with an audio CD or DVD when you insert it, so it opens Windows Media Player for you to use. However, you may not want this to happen. No problem, you can change it.
To stop Windows Media Player from opening when you insert a CD, follow the steps below:
1. Click Start--> My Computer. Right-click the CD or DVD-ROM drive that you want to configure, and then click Properties.
2. Click the AutoPlay tab--> Under Actions--> you can choose the Take No Action option so that Windows Media Player will not open and Windows XP will not prompt you for any action. If you want to be prompted--> just click the Prompt Me Each Time to Choose an Action radio button at the bottom of the window and click OK.
