Here is a transcript of the video.
Changing Your Password with Windows 10
Hopefully you are watching this because you need to change your Windows 10 password and you haven’t forgotten it. If that’s the case, the process is pretty straightforward.
Go to your “Start Menu” then to “Settings” and “Accounts”. In “Sign-In Options” select your account and you can change your password from there; it’s that easy.
But what If you’ve forgotten your password?
There are several options available to you with Windows 10. The first option is the Password Reset Disk. The problem with this option is that you have to have created this disk before you lost your password. For next time, let’s teach you how to create one. Go into your “Start Menu” then to “Settings” and “User Accounts.” Under “User Accounts” you’ll have an option to create a “Password Reset Disk.” You’ll need a USB or SD card inserted into your computer to do this. You just follow the prompts to create it. To use the Password Reset Disk when you need it later, you just insert it into your PC when you are at your login screen, hit “Sign-In Options,” find the location of the disk and it’ll reset the password for you. We’d advise you not to leave this disk sitting around for obvious reasons.
The next option is resetting your Microsoft Password online. This will allow you to recover your account name and password. It is going to make you jump through hoops in order to identify yourself but eventually it’ll let you recover either your password or username. This is probably your best option if you haven’t created your “Password Reset Disk.”
The last option will be a two-part option. You can either restore your computer to a previous state where your old password was still valid, or you can restore your system completely.
If you can remember your password in a time it worked, as your computer is booting up you can hit Shift and F-8 and it will load into an “Advanced System Startup Menu” to restore your system to an older previous version than it is now. The caveat is that you’ll lose all your data from that restore point onward.
If you are completely out of options and cannot recover your username, you’ll need to restore your system completely. You’ll hit shift F-8 as your computer boots up and get into your “Advanced System Startup Menu.” From there you can select “Repair Your Computer” and go to “System Restore.” If you look at that as an option instead of not being able to use your computer, this might be the lesser of two evils.
