In some cases, disabling the administrator account can cause maintenance difficulties. For example, in a domain environment, when the secure channel used to establish a connection fails for some reason, if there is no other local administrator account, the computer must be restarted in secure mode to fix the problem that caused the connection state to be interrupted.

If you attempt to re-enable a disabled administrator account and the current administrator password does not meet the password requirements, you will not be able to re-enable it. In this case, the optional member of the administrator group must set the password for the administrator account through the “local user and group" user interface.

XP uses a digital signature driver mode, the detection of various hardware is also stricter than before, so some devices may be under normal conditions Can not be driven to use. For example, some early CABLE MODEM, if you find that XP does not recognize the hardware in normal mode, you can press F8 at boot time, then choose to enter safe mode, detect new hardware in safe mode, it is possible to load CABLE MODEM correctly.
