In the following article, the network administrator will guide you how to reset the password of your Windows 10 login account without using any 3rd tool.
All you need is a Bootable Media drive that contains the Windows 10 installation. Also, you must use the appropriate 32-bit or 64-bit Windows installation disc, depending on the version of Windows you have installed.
If using Windows 10 x86, use the Windows 10 x86, Windows 8 x86 or Windows 7 x86 installation drive. In case your version is Windows 10 x64, use the Windows 10 x64, Windows 8 x64 or Windows 7 x64 installation drive.
This method of breaking Windows 10 passwords can also be applied on versions of Windows 7, Windows 8 / 8.1 and a similar way.
