You are trying to log in to your Windows 10 PC, but there is a problem: You have forgotten the password.
Do not panic. Windows 10 has long provided the ability to reset your password when using a Microsoft account. If you run the Windows Update on April 10, 2018 or later, you can also reset it using a local account.
If you have a local account, you need to set up multiple security questions to get answers to the case that you can not remember your login. Answer them successfully, and you can reset your password and access your account.
Check which version of Windows 10 is running by opening Settings> System> About . If 1803 or higher is specified in the Windows version, you are in business. If not, go to the "Update & Security" category in Settings and download the latest version of Windows 10, which is 1903 at this time.
