When you use full-screen mode to watch video in Windows Media Center, the screen saver may start on a Windows Vista-based computer

When you use full-screen mode to watch video in Windows Media Center, the screen saver may start on a Windows Vista-based computer.

This issue occurs if one of the following conditions is true:

• The On resume, display logon screen check box is selected on the Screen Saver tab of the Screen Saver Settings dialog box.
• The Require a password (recommended) setting is enabled under the Require a password on wakeup option of the Define power buttons and turn on password protection page.

To resolve this issue, enable the Don't require a password setting, and then click to clear the On resume, display logon screen check box. To do this, follow these steps:

1. Open Power Options. To do this, click Start

   , type personalization in the Start Search box, and then click Personalization in the Programs list.
6. Click Screen Saver.
7. Click to clear the On resume, display logon screen check box.
8. Click OK.

By default, the screen saver does not turn on in Media Center when you use full-screen mode to watch any one of the following items:

• TV
• A DVD
• A video
• A slide show
• A visualization while you listen to music

However, if you select the On resume, display logon screen check box or enable the Require a password (recommended) setting, the screen saver turns on when you use full-screen mode to watch live TV or a DVD. These settings help secure the computer when it is left idle.
