Q: Will I be able to access my files after resetting lost password with chntpw?
A: Yes, under typical, normal circumstances, you will have access to all files on the computer after resetting your password. In the rare case that you have any files that are encrypted, they will not be accessible without the original password. By default, files are NOT encrypted, so this is not likely going to affect you unless you knowingly turned on filed encryption.

Q: I’m still being prompted for my password after resetting it.
A: Depending on which version of Windows you are using, you may still be prompted for a password. If you’ve reset the password, then simply leave the field blank with nothing in the Password box. Most Pro versions of Windows will work in this manner, while Home versions will not prompt for a password if there isn’t one.
