Troubleshooting Windows Vista Programs and Features
Windows Vista has so many features and components that you are bound to run into
problems occasionally that I don’t address in other sections of this book. When you
run into these problems, please refer to this section for possible solutions for every-
thing from installation to playback in Windows Media Player.
Resolving Problems with Programs and Features
Table 21-2 provides an extensive list of problems you may encounter while working
with Windows Vista. The table is organized alphabetically by program or issue, fol-
lowed by details on problems you may encounter and possible resolutions to those
problems. In some cases, the resolution details will also point to a specific page
within the Microsoft Knowledge Base where you can look to find more information.

Program/Issue Problem/Resolution
16-bit DOS-based programs Some 16-bit DOS-based programs and the Command Prompt will not run in full-screen
mode in Windows Vista. This issue occurs because Windows Vista device drivers do not sup-
port running all of the DOS video modes. The Vista device drivers are based on the Windows
Vista Display Driver Model (WDDM). To resolve this problem, you may need to install a Win-
dows XP version of the video drivers for your video adapter.
Activation expires You see an error stating Youractivation period has expiredor that you have a non-genuine
version of Windows Vista installed. If you have not activated Windows Vista in the time
allowed oryou are running a nongenuineversion of Windows Vista, WindowsVista will run in
a reduced functionality mode. If you modify the computer hardware so that Windows Vista
determines that it is running on a different computer, Windows Vista will also run in a
reduced functionalitymode. Youll need to activate and validate Windows Vistaas necessary
to resume full functionality mode. See http://support.microsoft.com/kb/925582/en-us for
more information.
Activation fails Activation of Windows Vista fails over the Internet. If you connect to the Internet through a
proxy server where Basic authentication is enabled, you will not be able to activate Win-
dows Vista. Change the authentication method or see KB. Alternatively, when the Windows
Activation Wizard prompts you, click Use the Automated Phone System and then activate
Windows Vista over the telephone. See http://support.microsoft.com/kb/921471/en-us for
more information.
Administrator account The Administrator account does not appear on the Windows Vista Welcome screen. In Win-
dows Vista,the built-inAdministrator accountis disabledby defaultand youcannot use it to
log on to the computer in safe mode. However, during an upgrade, if the built-in Adminis-
trator account is the only active local Administrator account, Windows Vista leaves the built-
in Administrator account enabled and puts this account into Admin Approval mode. See
http://support.microsoft.com/kb/926183/en-us for more information.
ATM network adapters You receive an error message when you start Windows Vista after you install an ATM net-
work adapter. This error occurs because Windows Vista does not support ATM.
