After changing the administrator password Parallels user gets an error: "The user name or password is incorrect" on starting Vista.
Parallels Desktop for Mac application makes Vista installed in Express Mode log in as an administrator using a blank password by default. If the administrator password is changed, Vista will log in using the same blank password and this will lead to the error below:
"The user name or password is incorrect"
Please do the following in order to fix the problem:
1. Start the Virtual Machine.
2. Click the Start button.
3. Type "control userpasswords2" without quotation marks in the search field and press Enter.
4. Enable "Users must enter a user name and password..." option.
