Q: Which Windows operating systems will this work on?
A: Chntpw will reset your local passwords on any NT based Windows operating system including Windows NT, 2000, XP, Vista, Windows 7, Windows 8, 2003 and 2008 Server, as well as any versions not mentioned.
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.
Q: Could I use chntpw to reset Active Directory user password?
A: Chntpw doesn’t support domain controller. To reset lost AD password, you need to use some third-party tools such as PCUnlocker Live CD.
Q: Will chntpw work with Picture password, Pin code and Microsoft account in Windows 8?
A: Chntpw works with local account only. If you’ve forgotten your Picture password or Pin code, you can recover Windows 8 Pin code and Picture password using the freeware Mimikatz.
