I cannot sign in to certain applications I have a registered account with such as Open AI. I also cannot login to my computers MS Get Help Application as it says my account doesn't exist. However as you can tell I am logged into my Microsoft account right now. I get the error code "Account doesn't exist. Enter a different account or get a new one."

    Hi Elizabeth Mosher,

    Thanks for explaining what's happening. Since you're able to sign in to your Microsoft account on the web, but some apps such as OpenAI and the Windows Get Help app are telling you that the account doesn't exist, I'd like to understand a bit more about your setup before narrowing down the cause.

    Could you let me know:

    • What Windows version and build you're running? (Press Windows + R, type winver and share the result.)
    • Are you using a personal Microsoft account or a work/school account?
    • Does the issue only affect OpenAI and Get Help or are other Microsoft apps having trouble signing in as well?
    • Have you recently changed your Microsoft account email address, added a new alias or updated any account security settings?

    In the meantime, I'd suggest checking Settings > Accounts > Email & accounts to make sure Windows is using the same account you're trying to sign in with. If you have more than one Microsoft account, it's possible the affected apps are attempting to use a different one.

    You can also try repairing the Get Help app by going to Settings > Apps > Installed apps > Get Help > Advanced options, then selecting Repair. If that doesn't help, try Reset.

    I'd also recommend performing a Clean Boot to check whether a third-party application or service is interfering with the Microsoft sign-in process:

    1. Press Windows + R, type msconfig and press Enter.
    2. Open the Services tab and check Hide all Microsoft services.
    3. Click Disable all.
    4. Open the Startup tab and select Open Task Manager.
    5. Disable all startup items.
    6. Restart your PC and test signing in again.

    *Disclaimer: A "clean boot" starts Windows with a minimal set of drivers and startup programs. It helps to determine whether a background service is interfering with your game or program and to isolate the cause of a problem.

    These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by-step so that it will help you get back on track.

    If the sign-in works correctly in the Clean Boot environment, it usually indicates that a background application or service is interfering with the authentication process. You can then gradually re-enable services and startup items to identify the cause.

    Once you've had a chance to check the above and provide the winver information, I'll be happy to help you troubleshoot further.
