Click on CANCEL and Windows will load anyway.

The HELP file documents passwords (which function
mainly under the rubric of Networks.)

Click the cancel button to get into Windows.  Once in, delete the .pwl file
with your user name (mine is ron.pwl); however, be aware that you will lose
all passwords stored in the .pwl file.  Reboot and when the logon screen
appears, either enter a new password or if you do not want to logon at each
boot, enter a blank password.

Blank Password:  Go to control panel, network, primary network logon and
select Windows Logon.  Go to control panel, passwords, user profiles and
ensure the "all user's" box is marked.  If you have a password established,
go to control panel, passwords, change windows password, type the password
in the old box, leave the rest blank and OK your way out.  If you have
forgotten your password, delete the .pwl file with your user name (mine is
ron.pwl); however, be aware that you will lose all passwords stored in the
.pwl file.  If you do not have a password established or have deleted the
.pwl file, when the W95/98 logon screen appears at boot, type a user name
only and hit OK.  If the logon screen continues to appear and you have Tweak
UI installed, go to the Paranoia tab and remove the mark from "clear last
user."
