Hello Knickles,
We regret for the inconvenience. Let me assist you to resolve the issue.
Before we proceed any further, let us know a few more details on the below questions.
- Are you unable to login to Windows desktop when you say ' I cannot login to windows 10'?

Microsoft account has a security feature called
Trusted PC for verifying your identity automatically and performing sensitive actions.
You can mark a device as trusted just by selecting a check box. When you're prompted to enter a security code to verify your identity, select the
I sign in frequently on this device. Don't ask me for a code. check box, and we'll no longer ask you for a code when you sign in on that device.
Here's how to mark a device as trusted:
-
On the device you want to trust, go to the
Security settings page and sign in to your Microsoft account.
-
You'll be prompted to enter a security code. Choose whether to receive the code through email, text, or an
authenticator app. Once you have the code, enter it in the text box.
-
Select the I sign in frequently on this device. Don't ask me for a code. check box, and then tap or click
