STOP Bypassing win98/95 Login screen

Force Users to Logon to Windows (Windows 9x/Me)
Usually users can simply press 'Cancel' at the Windows logon box to bypass the login process and gain access to the local computer. This tweak will logout the user if the authentication fails or the user clicks Cancel.
Like all registry tweaks, this is for advanced users, please do not attempt to try this if you are not confident with the Windows registry and recovering from any subsequent problems.

Firstly, setup your computer for multiple users by using the 'Users' wizard in the Control Panel. Create a new user in addition to any existing users, then restart Windows and login as the new user (this will become your new default account).

While you are logged in open your registry and expand the [HKEY_USERS] key, there should be several sub-folders including ".DEFAULT", "Software" and a folder corresponding to the new username you created above.

Open the key listed below (if the 'Run' key does not already exist then createit), and create a new string value named "NoLogon", and set the value to equal "RUNDLL32 shell32,SHExitWindowsEx 0".

Log-off and now when you login using the new username you should gain access to the desktop, but when you press Cancel or enter the wrong password the desktop should partially load, and then the computer should return to the login screen.

(continued...)

Note: If you have problems with this tweak, press F8 while the "Starting Windows 98..." boot-up message is showing, and select Safe Mode. Then open your registry and delete the "NoLogon" key created above.

Note: Once this tweak has been implemented any subsequent users accounts that are created will inherit the 'NoLogon' value and therefore reboot when they login. To avoid this; when you first create a new user, open the key below for the newly created account name (e.g. [HKEY_USERS\jdoe]) and remove the 'NoLogon' value.

...there there is a nifty diagram....

Settings:
Key: [HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Run]
Name: NoLogon
Type: REG_SZ (String Value)
