Open command prompt. (Start > Run > cmd)

In it, type the following command:

net user YOUR_USERNAME NEW_PASSWORD

For example, we can say John wants to reset his password to moon123. He would enter the following:

net user John moon123

Now, if John wanted to clear the password from his account, he would enter the following:

net user John *

Hope this helps. :)
