Microsoft Edge has started testing a taskbar pinning wizard that helps you pin recommended sites and Microsoft apps to the Windows 10 taskbar. Facebook, YouTube, Wikipedia, Reddit, and Microsoft News are among the sites you can pin to the taskbar when browsing a web site. The current choices are Microsoft Office, Microsoft News, and Bing. For most people, this feature will be fairly useless and users are better off just pinning the sites they use and skipping this wizard altogether. The wizard appears to be nothing more than a tool to promote Microsoft’s sites and other well-known sites.
