Question

Windows: Sign-in popup closes instantly. Tried everything; issue for months.

Atlas Pettersson 0

Hello,

I have been unable to sign in to my Microsoft account for several months.

Every time I click the "Sign in" button, the sign-in window appears briefly and then immediately disappears. Nothing else happens, and I do not receive any error message. I am never able to complete the sign-in process.

I am using a Windows PC, and I have already tried numerous troubleshooting steps and solutions that I found online and through previous support articles. I have essentially tried everything I could find, but the issue still persists.

Could you please help me identify the cause of this problem and provide a solution? If you need any additional information, I would be happy to provide it.

Thank you.

Hi Atlas Pettersson,

Please note that this is Microsoft Q&A community for Swedish region. However, you have made this thread in English, so I will respond in English also.

Could you please list the methods that you have tried?

In the meantime, did you try to sign-in with a newly created Edge profile?

If you have further information, please feel free to let me know.

Hello,

Thank you for your reply.

I have already tried numerous troubleshooting methods over the past several months, including restarting my PC, resetting Microsoft Store, running SFC and DISM scans, clearing cache, updating Windows, repairing/reinstalling Microsoft Edge and WebView2, and other solutions suggested online. Unfortunately, none of them resolved the issue.

For clarification, whenever I click Sign In, the login window appears briefly and then closes immediately without any error message. It does not matter what account I click, or if I click to create a new one.

Thank you.

Hi Atlas Pettersson,

May I ask did you try performing an In-place upgrade or a clean install?

Hello,

No, I have not performed an in-place upgrade or a clean installation of Windows.

Before considering those options, I would like to know if there are any other troubleshooting steps available, as this issue appears to be specifically related to Microsoft account sign-in windows closing immediately.

Thank you.

Hi Atlas Pettersson,

Can you sign in normally to Microsoft with your browser?

Hello,

Yes, I can sign in to my Microsoft account through a web browser.

However, I cannot sign in through Microsoft Store or other Windows apps. When I click Sign In, the Microsoft sign-in window appears briefly and then closes immediately without any error message.

The issue seems to affect the Windows sign-in dialog itself rather than my Microsoft account.

Thank you.

Hi Atlas Pettersson,

Thank you for your information.

I suggest that you try performing an In-place upgrade as mentioned above. Your data should stay intact.

If you have further information, please feel free to let me know.

Hello,

Thank you for the suggestion.

Before performing an in-place upgrade, are there any logs, Event Viewer entries, or diagnostic steps that could help identify the exact cause of the issue?

Since the problem seems to be specifically related to the Microsoft sign-in dialog in Windows, I would like to understand what component is failing before proceeding with a Windows repair installation.

Thank you.

Hi Atlas Pettersson,

The logs might appear on Event Viewer:

Windows Logs > Application: Look for sources like:

Application Error

Microsoft-Windows-WebAuth

Microsoft Account

AAD

App-specific (Edge, OneDrive, Teams, Outlook)

Applications and Services Logs > Microsoft > Windows > WebAuth

Tracing the failing component in this case may be quite challenging.

Hello,

I checked Event Viewer as you suggested.

There are no relevant errors or warnings in Windows Logs > Application. The only new entries are unrelated Windows Update events.

I also checked Applications and Services Logs > Microsoft > Windows > WebAuth. The Operational log contains no events, even after reproducing the issue.

It appears that the sign-in window closes before any WebAuth events are logged.

Please let me know if there are any additional diagnostic logs or tools I can use before performing an in-place upgrade.

Thank you.

Hi Atlas Pettersson,

Currently, I am unable to determine the exact root cause of the issue. Since an in-place upgrade is generally considered a safe repair option, it may be worth trying to see whether it resolves the problem.

Hello,

Thank you for your assistance and suggestions.

At the moment, I am on vacation and do not have access to my computer, so I am unable to perform any further troubleshooting right now.

Once I return and have access to my PC again, I will continue with the diagnostic steps and let you know the results.

Thank you for your patience.
