Highlights

• **New!**The coming weeks will bring a richer weather experience to your lock screen. This includes dynamic, interactive weather updates. So, as you hover over the weather on your lock screen, you will see more information. When you tap or click on the weather card and sign in, Microsoft Edge opens with the full forecast in MSN weather. If you already use Weather in Settings > Personalization > lock screen > Lock screen status, there is nothing for you to do. Also, this new experience will be on by default if Lock screen status is set to “None.” Like today, lock screen status will be available when you lock your screen no matter which personalization option you select (Windows spotlight, Picture, or Slideshow).
• This update addresses an issue that affects the spellchecker.
