Windows 8.1 has a new search screen that allow users to search online for a lot of things, similar with the one from Unity Smart Scopes. The difference is that Windows 8.1 searches on Bing, Microsoft’s search engine, and has results also from Microsoft services, like Skype or Sky Drive, while 100 scopes is capable of searching on many sites.
