Windows XP is sometimes safer without a password

Microsoft wrote in an official guide: At some point, rather than setting a weak password, such as abc123, it is better to not set a password.
This is because Windows XP accounts are not accessible from remote networks and the Internet without password protection.

Microsoft is guiding users in the documentation. The following guidelines must be followed when using a blank password under Windows XP:

You only have one computer, or you have several computers, but your other computers do not. Need to get information on this computer.

Computers are physically secure (no outside contact)

Using a blank password is not always a good idea, especially if the computer is not in a safe place, for example Say, a laptop, you bring out the door, using a blank password may not be safe, so you should have a strong password. If you want to enter your XP Pro computer network and the password is blank, you can fix it in Group Policy.
