Microsoft releases three updates for Windows 10 Preview build 10041 - addresses vulnerabilities, fixes transparent Start Screen and task view issues

Microsoft has released three new updates for Windows 10 build 10041, which was recently released to Insiders on the Fast Ring of the Windows 10 Technical Preview

The update addressing issues with the Start screen transparency, includes a fix for the Task View, and a patch for a pretty nasty vulnerability that facilitates exploitation of the publicly disclosed FREAK technique.

Update (KB3050284)

• This update resolves a problem that may result in a transparent Start screen and Task view, transparencies when snapping or dragging windows, and can cause desktop thumbnails to appear as black squares.
• This update resolves a problem that results in severe graphical artifacts on screen when Magnifier is launched in docked or lens mode.
• This update contains a reliability improvement to resolve a common system crash.

Update (KB3050279)

• Sharing the desktop in a meeting causes remote users to see a black rectangle instead of the desktop in the Lync client.
• On Microsoft Surface Hub, selecting the I’m Done button may cause the user interface to crash, thus making the Call, Whiteboard, and Connect buttons nonfunctional.
• If the Connect app is closed via the task switcher and then restarted, it may crash.

Patch (MS15-031)

• This security update resolves a vulnerability in Microsoft Windows that facilitates exploitation of the publicly disclosed FREAK technique, an industry-wide issue that is not specific to Windows operating systems. This vulnerability could allow a man-in-the-middle (MiTM) attacker to force the key length of an RSA key to be downgraded to EXPORT-grade length in a TLS connection. Any Windows system that uses Schannel to connect to a remote TLS server by using an insecure cipher suite is affected.
