Hi Ellen Lervik,
I understand how frustrating that would be, especially when the pop-up is interrupting Win + Shift + S screenshots.
First, could you clarify:
- Are you signed in to Windows with a Microsoft account or a local account?
- Does the pop-up appear only when using the screenshot tool, or does it also appear at other times?
- Did this start after a recent Windows update or account change?
Based on the message "Sign in so you don't miss out", I suspect Windows is showing a Microsoft account setup/re-engagement notification rather than a sign-in failure. Microsoft documents that these notifications can be controlled through the Windows notification settings.
In the meantime, please try:
- Open "Settings" > "System" > "Notifications".
- Expand "Additional settings" at the bottom of the page.
- Uncheck:
- "Show the Windows welcome experience after updates and when signed in to show what's new and suggested" (if applicable)
- "Get tips and suggestions when using Windows"
- Restart the PC and check whether the pop-up still appears when taking a screenshot.
