When you start the computer, it now takes 20 minutes to complete the logon process. Once the computer is started, you cannot use any hardware connected to the computer. You discover the Plug and Play service is stopped, but you cannot get it started.
The Plug and Play service is the basis of all Windows services and must be running to have a stable system. However, once Windows is started, the service cannot be started.
First, you should start the computer from a bootable Windows XP Professional CD-ROM. Enter the Recovery Console before Windows starts. Enter R to repair the installation when the Welcome to Setup screen appears.
Choose the Windows installation to repair and enter the Administrator password.
You will be taken to the command prompt. At the prompt, type ENABLE PlugPlay SERVICE_AUTO_START. This command configures the registry to start the Plug and Play service automatically right after Windows starts but before the logon process. You should then restart the computer by typing EXIT.
