If you use a local account in Window 10, you should create a password reset disk using a USB flash drive as soon as possible. Then, if you forget your password, you can reset it. If you wait until you've forgotten your password, it'll be too late. If you’re using Windows 10, version 1803 you can add security questions to your local account in case you forget your password, so you don't need to create a password reset disk. To do this, select the Start button > Settings > Sign-in options > Update your security questions.
Make sure you're signed in with your local account. This won't work with Microsoft (connected) accounts.
- Plug a USB flash drive into your PC. Although creating a password reset disk won't reformat your USB flash drive, you should back up any data on it before you continue.
- In the search box on the taskbar, type create password reset disk, and then choose Create a password reset disk from the list of results.
In the Forgotten Password wizard, select Next. Choose your USB flash drive and select Next.
Type your current password and select Next. When the wizard is done, select Finish.
- Remove the USB flash drive and keep it in a safe place where you'll remember it. Note that you don't have to create a new disk when you change your password—even if you change it several times.
