Microsoft Virtual PC virtual machines, including XP Mode, require a password when
Integration Components are installed and enabled. There are no workarounds. Simply:
- Integration enabled > to login the user account used must have a password
- Integration disabled > login possible also to user accounts which do not have a password
If you have removed the password from an user account in XP Mode and can't log in to it, log in to another user account with admin rights, goto XP Mode
Control Panel > Users and set a password to that account with no password.
If you have removed the password from all user accounts with admin rights, boot XP Mode and when in login screen, disable
Integration Features from
Tools menu:
Now you can log in to accounts which have no password.
If you have problems to get in to the login screen or to disable Integration Features from Tools menu, close XP Mode and delete the hibernation file as told in my first
reply, then disable Integration from
XP Mode settings by deselecting
Enable at startup as shown here:
Now start XP Mode, login with no password, goto
Control Panel > Users and set password, enable Integration from Tools menu and everything will be fine again

.
