If you’re testing the Windows 10 Technical Preview, the first new build is now being rolled out. It’s snappily titled build 9860.
You’ll get the build automatically, and it will be downloaded with no input from you if your PC is plugged in, on or sleeping. To get it manually, open PC Settings > Update > Preview Builds, then click the Check Now button to get the new build. The download will be between 2 and 2.74 GB, depending on your PC specs. Once your PC has installed the build and rebooted, eventually you’ll see Windows 10 as you left it, with all the apps and everything else you’ve installed.
What’s new in Windows 10 Technical Preview build 9860
Action Center for Windows PCs. As we showed a while ago, Windows 10 will have a notification center like other operating systems, although it was hidden in the first public build. Microsoft is calling it Action Center – it’s notifications that you can click to act on them.
Better multiple monitor support. Now you can move apps between multiple monitors, with WIN+SHIFT+. There are more new shortcuts for managing multiple desktops, which Microsoft has published here.
Desktop switching animation. Users said switching between desktops wasn’t clear enough, so a new animation has been added to make it easier to notice.
User ideas from the Suggestion Box and Windows Feedback Tool, according to Microsoft, are being sorted through and the good ones will be part of future developments. It encourages everyone to give feedback on the Windows 10 Technical Preview using the Feedback app.
Download Windows 10 Technical Preview. You can use it until April 15th 2015
