how to make this disappear

Disable the item from Notifications & actions if it appears as a notification; otherwise, turn off Windows tips and Settings suggestions using the matching steps below.

If it appears in the lower-right corner or Action Center

1. Press Windows key + A.
2. Locate the unwanted “Microsoft Help and Learning” or “Get Started” item.
3. Select its Settings button, then choose Turn off all notifications for the sender.
4. Alternatively, open Start → Settings → System → Notifications & actions.
5. Under Get notifications from these senders, turn off the sender shown on the unwanted notification. Do not expect it necessarily to be named “Get Started.” ^1^

If you do not want notifications from any apps, turn off Get notifications from apps and other senders on that same page. This also suppresses notifications you might want, such as mail or calendar alerts.

If no matching sender is listed

In Start → Settings → System → Notifications & actions, turn off or clear any options worded like:

• Show me the Windows welcome experience after updates and occasionally when I sign in
• Get tips, tricks, and suggestions as you use Windows

These controls target Windows welcome screens and tips rather than notifications from a particular application.

If it appears inside the Settings app

1. Open Start → Settings → Privacy → General.
2. Turn off Show me suggested content in the Settings app.

Microsoft documents this as the per-user control for suggestions displayed in Settings. ^2^

If it still appears, attach a screenshot with personal information hidden and indicate whether it appears at sign-in, inside Settings, in a browser, or in the lower-right corner. The words “Microsoft Help and Learning—Get Started” alone do not establish which Windows component is opening it, so disabling unrelated services or startup programs is not recommended yet.
