The Windows 10 Technical Preview is well under way, and while Microsoft has yet to release another build to the public, that hasn't halted certain folk from publishing screenshots of unreleased builds. Improvements have been spotted in build 10036.
To select a new Wi-Fi network in current builds will see you opening up the Settings app to carry out the task, but in the new screenshots we can clearly see a new wireless networks panel. This should hopefully allow more convenient access to multiple networks in range, without having to hunt deep through menus.
We're sure things will change in the future, so do excuse the rather 'rough' look. As well as the Wi-Fi panel, there are also a few changes in the Task View too, including a "New Desktop" entry in the bottom right hand corner and the ability to drag apps across desktops. Check the video below for a quick demonstration.
