Windows 8.1 Preview
One of the most anticipated changes is the return of the start button. That's something Microsoft leaders say many users complained about after the company eliminated the tool.
Also coming is built-in support for 3D printers, as those devices continue to grow in popularity.
Other changes in Windows 8.1 to watch for include: improvements to the "Bing" search engine, an updated X-box music app and new developer tools.
The new search engine is designed to get users what they want and fast. Just one search will bring users information from their PC, apps or the web. Of course, because this is a Microsoft product, it's all powered by Bing.
Windows apps will also get an update to allow users more functionality. For example, there's a new photo editing app to give your pictures a creative edge. That goes along with the redesigned Windows store too.
And there's a bunch of cool ways to customize your background with pictures and video.
Microsoft announced the new features at its developers conference in San Francisco on Wednesday.
Look for these updates in new versions of Windows and updates to the original Windows 8 later this year.
