This is a discussion thread for the "Windows 8 Has Built-In Ads, But Don't Panic" story posted on the front page.
The ads are hidden WAY in the back, or in a convenient tile where it almost goes unnoticed, so honestly this is something I never really minded. It even gave me a nice app to download from the Store, so they're some decent ads to say the least. If they become anything like Xbox ads, they'll be fun to click on.
I knew since the first time I got Windows 8 (2-3 days after official release). It never bothered me, but I can see how it can bother others.
