microsoft.com (frontpage is enough)
It's a dumbed down, extremely simple version of the front page of microsoft.com, with the first section showing news-like snippets of the content of the 4 main links: Microsoft 365 (which includes Office), Windows, Xbox and Surface. The rest are the other less relevant Microsoft-related links from the "All Microsoft" section. They took me some time to type in).
The rest of the functionality (Account and shopping, support-related) aren't included. Other event-related content isn't included.
Edit: I feel like I should say - if you are new to things, please don't feel discouraged by criticism. Everyone starts somewhere.
Edit: Checked in Firefox. I'll be polite and just leave it at "Oh, dear."
