Windows 10: Passwords seem to get lost

Hi Jackie,

In cases wherein you cannot log in to your Windows 10 computer, we need to consider if you are typing the correct password or if you are logging in to the correct account. To better assist you, we need the answers to the following questions:

• Are you using a Microsoft account or a local account to log in to your computer?
• Have you tried
  resetting your Microsoft account password?

In the event that you are using a local account on your Windows 10 PC, we suggest following the steps in this

article to reset your Windows 10 local account password.

We are looking forward to your response.

 

Windows 10 Tweaks

As you may already know, Windows 10 (as well as Windows 8) allow you to log in with a valid Microsoft account, instead of creating a local account that only works on your machine. However, you may prefer to keep a local account for privacy reasons. If you do, though, some Windows 10 features—like Cortana—may not work. Despite the default behavior, the Windows 10 Store is not one of them. You can still log in to your Microsoft account for just the Store without switching to a full Microsoft account. The process, however, is not terribly obvious. To do so, follow these steps:

• Launch the Store from your Start menu.
• Click the user icon next to the search box.
• Click “Sign-in” from the menu that appears.
• Choose “Microsoft account” and log in like normal.
• When the “Make it yours” box appears do not enter your password. Instead, click “Sign in to just this app instead.”
