Unlike the traditional logon mode for Windows 2000, Windows XP uses the Welcome screen to manage account logins by default, and if you use the traditional login mode for Windows XP, you can use the start → settings → control Panel → user account → change the way users log on or off "Use Welcome screen" To turn on the Welcome screen login mode.
1. Uncover the "vanishing" mystery of the Welcome screen
If you've already turned on the "Use Welcome screen" mode, but you're still not looking at Windows XP, just log in. If the system is in a workgroup, there may be two reasons: one is that the system has only one account, the password is not set, and the guest access is not turned on, and the "Fast User Switching" feature is turned on. To retrieve the disappearing Welcome screen, we can create a new account or set a password for an existing account, and if the problem has not been resolved, run the Regedit command to open Registry Editor and navigate to the [Key_local_machine\software\microsoft \
Windows\currentversion\policies\explorer] Branch, find Nowelcomescreen in the right window (if none is new, its type is DWORD), modify its value to 0.
2. Rescue was "tampered" with the Welcome Screen interface
When we install some software, such as PC anywhere, they will modify the Windows XP Welcome screen style, to restore first run the "Regedit" command to open Registry Editor, delete "[Key_
Local_machine\software\microsoft\windows nt\
Currentversion\winlogon] under the GinaDLL item. If you use a VPN (virtual private network), it will also cause the Welcome screen to be modified, and the method of recovery is to locate and delete GinaDLL in the right window after locating the above registry branch.
