IMPORTANT WINDOWS TIPS

Automatic logon without name or password (9x)
This setting allows Windows clients to logon without entering a user name or password, therefore bypassing the logo box. Create the string value Default Password, under Winlogon (see key below). Modify the Default Password's data to match the default users password. The default username is stored at:[HKEY_LOCAL_MACHINE\Network\Logon]-Username
Reboot and the system should automatically logon.
NOTE: The password is stored in clear text.
Key: [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Winlogon]
Value Name: Default Password
Data: REG_SZ
