Windows Server Insider Build 16257 released

Posted on

The Windows Server Insiders Team has released a new build for those running the new Windows Server Insider Preview. The Windows Subsystem for Linux has been released on the Server build, which is a great addition. Check out the blog post for more.

What’s New in Build 16257 for Windows Server

Windows Subsystem for Linux (WSL) is available on Windows Server

  • Windows Subsystem for Linux (WSL) is now available on Windows Server along with a compliment of Linux distributions.

  • Test WSL on Windows Server.  WSL runs unmodified Linux (ELF64) binaries natively.  With the additions of WSL you can run node.js, Ruby, Python, Perl, Bash scripts or other tools that expect Linux behaviors, environment, or filesystem-layout, the ability to install and run Linux with WSL expands the tools at your disposal on Windows Server.

  • At this time, WSL does not support persistent Linux services (such as daemons and jobs) as background tasks. To enable WSL and install a Linux distribution, see Enable the Windows Subsystem for Linux and Install a Linux distribution in the Windows Server 2016 Installation Guide on GitHub.

  • Read more in this blog or follow the installation guide to try it out.

Fast Ring Build Released–Build 16251

Posted on

A new build, 16251, has been released to the fast ring. Quite a few nice additions in this build, but the Settings page is going to start getting crowded!

As always, make sure and read the known issues before upgrading. You might find a show stopper in your case. Many times, it’s an issue that is just annoying or doesn’t affect you at all.

Known issues for PC

  • If you installed Builds 16226-16237 and upgrade to this build, Storage Spaces will not work correctly. While Build 16241 contained a fix for the general reported issue with Storage Spaces in that build range, we discovered that the fix only applies for computers not already in the bad state, and need to do some extra work to return those already impacted to the good state. Special thanks to the Insiders that have helped us investigate this!

  • Trying to use the dictation hotkey (WIN + H) in UWP apps won’t work – you’ll see the UI come up and immediately dismiss. If you’d still like to use dictation, the microphone in the touch keyboard will work. You can right-click the Taskbar for an option to show the touch keyboard button if it’s not already visible.

  • We’re investigating your reports that after upgrading to the latest Insider Preview builds, some network settings are lost and revert to default settings. Static IP address configuration is reverted to DHCP. Networks which were marked as private are reverted to public. After the upgrade you will need to manually readjust your network settings back to your preferred settings.

  • Start, Action Center and notification toasts may at times have a background that is 100% transparent. A fix will be available in later flight – for now, if you encounter this issue, try ending ShellExperienceHost.exe via Task Manager or rebooting to resolve the issue.

  • Connecting to a VPN using a solution downloaded from the Windows Store may result in a system crash.

  • The battery flyout might show unexpected text for the % charged (specifically “%1!s!%2!s!% until fully charged”).

Announcing the Windows Bounty Program

Posted on

Microsoft has announced the Windows Bounty Program for computer security professionals (or those that enjoy looking for security vulnerabilities). The target areas are the Windows Insider slow builds of Windows 10, Hyper-V, Microsoft Edge, Windows Defender Application Guard and the mitigation bypass and bounty for defense. The payouts for finding an exploitable vulnerability range from $500 – $250,000.

The overall program highlights:

  • Any critical or important class remote code execution, elevation of privilege, or design flaws that compromises a customer’s privacy and security will receive a bounty
  • The bounty program is sustained and will continue indefinitely at Microsoft’s discretion
  • Bounty payouts will range from $500 USD to $250,000 USD
  • If a researcher reports a qualifying vulnerability already found internally by Microsoft, a payment will be made to the first finder at a maximum of 10% of the highest amount they could’ve received (example: $1,500 for a RCE in Edge, $25,000 for RCE in Hyper-V)
  • All security bugs are important to us and we request you report all security bugs to secure@microsoft.com via Coordinated Vulnerability Disclosure (CVD) policy
  • For the latest information on new Windows features included in the Insider Previews, please visit the Windows 10 Insider Program Blog

Critical Flaws in Windows NTLM Protocol

Posted on

This Patch Tuesday from Microsoft includes patches for Windows that affects all Windows OS’s released since 2007. Swati Khandelwal has a post about the new vulnerabilities and how they could be exploited. Make sure you run Windows Update to grab the latest updates and protect yourself from these vulnerabilities.

Researchers at behavioral firewall specialist Preempt discovered two zero-day vulnerabilities in Windows NTLM security protocols, both of which allow attackers to create a new domain administrator account and get control of the entire domain.

NT LAN Manager (NTLM) is an old authentication protocol used on networks that include systems running the Windows operating system and stand-alone systems.

Although NTLM was replaced by Kerberos in Windows 2000 that adds greater security to systems on a network, NTLM is still supported by Microsoft and continues to be used widely.

Build 16232 for PC and 15228 for Mobile Released

Posted on

I’m getting slow! It’s been a couple hours since these were released. Build 16232 for the PC and 15228 for Mobile have been pushed out to Fast ring insiders. Some new Windows Defender features that sound nice.

Make sure to read the Known Issues before updating. Some might be a deal breaker for you, or you might have a problem and want to report it but it’s already known.

Known issues for PC

  • Your PC may fail to update to this build with an 0x80070643 and rolls back to the previous build. We are investigating.

  • We’re continuing to investigate reports that the battery status on certain laptops isn’t updating while the device is unplugged. If you think you are seeing this, please send in feedback via Feedback Hub and use the capture feature when logging your feedback so we can get your logs.

  • You may notice some of your inbox apps are now displaying a name that looks like “ms-resource:” and are listed at the bottom of Start. We’re investigating. In the meantime, the app should still launch normally, it’s only the name resource that’s impacted.

  • Some UWP apps such as Twitter will crash on launch.

  • Xbox Live in-game experiences may fail to load. These include gamer profiles, achievement details, and other dialogs that may pop up on top of an Xbox Live-enabled game.

  • Please avoid doing a PC reset via Settings > Update & security > Recovery and choosing “Remove everything”. This may put your device into a reboot loop.

  • Task Manager may hang on launch on this build.

The New Surface Pro Arrives

Posted on

Well, Panos wasn’t wrong – the Surface Pro 5 does not exist. The new Surface Pro (with no identifying sequence number) has been announced. As expected, it’s a small upgrade from the Surface Pro 4. Higher battery life, quieter fans (the i5 doesn’t even need a fan), lighter, the new pen…

With a powerful 7th generation Intel Core processor it can handle almost anything you throw at it, but even with all that power, you can be as inconspicuous as you want with Surface Pro, it’s the quietest Surface yet, with no fan on the Core™ m3 and the i5 devices. In fact, this is the first i5 ever with fan-less architecture. And at an unprecedented 18dB, even the core i7 can’t be heard. So, if you’re working at home, you don’t have to worry about your family getting disturbed by the noise of a fan while they’re trying to watch a movie.
