1. Delete the *.PWL files in C:\Windows
2. Open the control panel, networks and set the logon to Windows.
3. Ok your way out and reboot.
4. Answer the logon for the last time by typing in the name, do not touch the Password box and click OK.
If you don't follow the steps, it might not be heaven.
I have an old W98SE and each time I boot up it asks for Password. How do I deactivate that?
