After logging on for the first time, if you change the background color to a solid color other than black, the background changes back to solid black after the second logon.

Note: To configure the desktop background to a solid color, follow these steps:

1. Right-click on the Desktop then click on [Personalize].
2. Click on [Desktop Background] then select [Solid Colors] under [Location].
3. Choose one of the solid colors listed other than black.

You configure a Windows Vista-based or Windows Server 2008-based computer to log on automatically on startup. However, after the logon process is complete, the icons on the desktop are unexpectedly rearranged. This situation occurs even though the Auto Arrange setting is turned off.

This problem occurs on certain models of computers. It is likely to occur on computers that have an extra-wide screen, such as a screen that supports a 1600 × 900 resolution. This problem may also occur on computers that have hybrid GPUs connected to one monitor.

After logging on to a Windows Vista or Windows Server 2008 computer, you are presented with a blank screen with no Start Menu, shortcuts, or icons. If you reboot and use F8 to boot to Safe Mode with Networking, you will see your normal desktop.

You may see the following events in the Application log:

When you run a 16-bit application on a Windows Vista-based or Windows Server 2008-based computer, some controls in the application are not painted correctly. Therefore, the application’s user interface (UI) is not displayed correctly.

This problem occurs when the Desktop Window Manager Session Manager service is disabled on the computer. If you enable this service, this problem no longer occurs.

Notes

• By default, the Desktop Window Manager Session Manager service is disabled when the system is hosted on a virtual system such as Microsoft Virtual PC.
• This is a known issue in the Threed16.ocx control that is included with Microsoft Visual Basic 4.

Consider the following scenario:

• You log in to a Windows 2008 Server using Remote Desktop.
• You are using a roaming profile.
• Icons are viewed as Large or Middle size icons (shortcut (.url)) on desktop.
• You have changed an Icon image to be different than its default icon.

In this scenario when you use remote desktop you notice that the icon that is displayed for Internet shortcut files changes to the default system icon.

After an unattended installation of Windows Vista Service Pack 1 (SP1), the customized desktop wallpaper is replaced by the default Windows Vista wallpaper. Typically, this issue occurs if the customized desktop wallpaper is stored on a network share or is located in the user’s redirected My Documents folder.

On a Windows Vista based computer that runs Symantec AntiVirus 10.2 client, you enable EFS for documents on the Desktop or in the Documents folder. After you reboot the computer and log on again, the encrypted files cannot be decrypted.

The problem does not occur when folders are encrypted in other locations.

Also, when Symantec AntiVirus is uninstalled the problem goes away.

Consider the following scenario:

• You run the System Preparation Tool (Sysprep.exe) against a Windows Vista installation.
• You use the Oobe.xml file to customize the desktop wallpaper.
• You use an answer file to implement unattended settings. The unattended settings include specific language and locale settings.

In this scenario, the desktop wallpaper that is specified in the Oobe.xml file is not displayed.

If for some reason the “Certified for Windows Vista” logo excites you, you better get a change of cloths when you look at this new desktop wallpaper featuring the logo, and the slogan “Little Logo. BIG IMPACT.” Keep reading →

Consider the following scenario:

• On a Windows Vista-based computer, you redirect the Desktop folder to a network redirection folder.
• You enable the Always Available offline option to make the Desktop folder available offline.
• The computer is connected to a network that does not contain the redirection folder.
• You restart the computer, and then you enter your user credentials on the Welcome screen to log on to the computer.

In this scenario, you see a black screen for 30 to 120 seconds before the desktop or the Start menu appears.
