Safe Mode with Networking
There are a couple of variations of safe mode. You can select safe mode with networking, which is identical

you restart your computer. Safe mode with networking allows Group Policy to be implemented, including
those implemented by the server during the logon process and those configured on the local computer.
Safe Mode with Command Prompt
A second variation of safe mode is safe mode with command prompt, which is similar to safe mode, but it
loads the command interpreter as the user shell, so when the computer restarts it displays a command
prompt.

the registry information that Windows XP Professional saved at the last shutdown.
If you change the Windows XP Professional configuration to load a driver and have problems rebooting,
you can use the last known good process to recover your working configuration. The last known good
process uses the LastKnownGood configuration, stored in the registry, to boot Windows XP Professional.
Windows XP Professional provides two configurations for starting a computer, Default and
