“We’ve been working to add more valuable content to our initial recommendations section, and are excited to introduce a new type of content: Sites,” Microsoft said.

In the first stage, we will recommend some commonly used websites to you based on your region and browsing history to help you easily find the websites you care about. You can right-click on a site to choose to delete that site individually or stop showing all recommended sites altogether. Of course only some internal testers will see this experience at the moment, if you see it, please share your opinion.

In response to user requests, Microsoft has introduced the ability to display seconds on the system tray clock. You can enable it through the option listed in the taskbar “Settings > Personalization > Taskbar”. Of course, you can also right-click the taskbar to quickly enter the taskbar settings.
