Windows 10 signed you in with temp account? Here's the fix.

Are you getting an account error message as soon as you sign in? If so, then Windows 10 likely signed you in with a temporary account. Here's how to troubleshoot the issue.

On Windows 10 after an upgrade, installation of a new monthly update, or antivirus setup, you may receive the "We can't sign in to your account" or "You've been signed in with a temporary profile" error message as soon as you sign in to your account. When this happens, then the system signed you in using a temporary account, instead of your original account, and any changes you make in this session will be discarded as soon as you sign out.

Thankfully, if you end up on a temporary account on Windows 10, there several sets of instructions that will help you to overcome this problem on your device.

In this Windows 10 guide, we'll walk you through a number of ways you can troubleshoot and resolve the account error messages.
