We set the computer an access password to prevent unauthorized use of our PC. But sometimes we may forget or misremember the password and can not enter the system, thus shut ourselves out. In this case, reinstalling the entire operating system is obviously an inadvisable option. Instead, you can use NTPWEdit this tiny app to modify or remove any existing password of local system accounts easily.

For privacy protection and data security purposes, it is very necessary to set a login password for the Windows user in use in many environments (especially the public places). But sometimes, we may forget our login password for those computers we don't use very often, or remember the wrong password, and fail to log in. This case, reinstalling the operating system is a inadvisable bad plan; and taking brute-force password cracking is extremely inefficient. Therefore, clearing the original user password has always been the first choice - also the easiest and most efficient way.
