After last weeks announcement of the Creators Update, Microsoft Windows 10 Insider Build 14959 rolling out today to PCs and phones in the Fast ring. Also, introduced today is a Unified Update Platform (UUP), next generation of delivery technologies that works across PC, tablet, phone, IoT, and HoloLens.
First up, Microsoft notes that over 400 million devices running Windows 10 to date and release new builds to Windows Insiders nearly every week.
The UUP technology incorportaed into the latest Insiders builds offer benefits with "reduction in download size on PCs." Now, as the company says when an update is available, "a differential download package that contains only the changes since you last updated your device" will be offered, rather than a full build.
"when your device checks for updates, the Windows Update service will evaluate which updates are needed by a given device. The Windows Update service then returns these updates to the device for download and install," Microsoft stated.
But that's not all, with UUP, "updates check" is also becoming more efficient, with the reduction of the amount of processing time as well as the amount of data sent to client devices. Because more processing is being done by the service, "this will lead to faster checks for update operations."
Finally, this will also end "two-hops: updates on phones, which is require to get on to current build today. Because, UUP now adds a logic in the client that can "automatically fallback to a "canonical" build," and updates the phone in just "one-hop", just like the PC.
Further, Microsoft says, the impact of the UUP rollout will be more visible on PCs "where users can expect their download size to decrease by approximately 35%,," when going from one major update of Windows to another.
UUP is made to work on both the Mobile and PC OS. It's available for Mobile in today's Windows 10 Mobile Fast ring build, which is published through UUP.
For PCs, UUP is expected by later this year, as Microsoft says, they're bringing this "for feature updates after the Windows 10 Creators Update," however Windows Insiders will see this sooner, Microsoft said.
IoT and Windows Holographic will come "shortly after" that, which likely means 2017.
This build among other new features and fixes comes included with features such as the Paint 3D Preview. Creators Update will come to Insiders in the next couple of months.
Controlling the Display Scaling of your Virtual Machines (PC):
This build also adds a new Zoom option in the View menu to scale the dspaly of Hyper-V Virtual Machines on the PC. You can now override default scaling, and set it to 100, 125, 150 or 200. Along the way, a fix is also made where certain VMs wouldn't display the remote desktop connection bar after entering full screen mode.
Below you will find the full changelog of this build (verbatim).
Other improvements and fixes for PC
- We fixed an issue for Insiders resulting in the automatic brightness setting unexpectedly being turned off after upgrading. In doing so, we've re-enabled automatic brightness adjust for users that have never changed their auto-brightness setting. If you have already manually configured your auto-brightness setting, then this fix will not affect you. If you would like to enable or disable automatic brightness adjustment, please go to Settings > System > Display, where you can adjust your preferences.
- We fixed an issue Insiders on domain connected PCs may have experienced where login might fail when the computer was disconnected from its domain network.
- We fixed an issue resulting in certain apps, such as Outlook Mail and Calendar, failing to update for some Insiders with the error code 0x800700B7.
- We fixed an issue for Insiders with certain device models where ejecting an SD card might result in a system crash.
- We fixed an issue where disliking one of the Spotlight lock screen images would show the new image immediately, followed by a transition animation from the previous image to the new image.
- We fixed an issue where launching an app from another app while in Tablet mode no longer launched it side by side, and instead launched it fullscreen (for example, when launching a web link from the MSN News app).
Other improvements and fixes for Mobile
- The data usage page in Settings via Settings > Network & wireless > Data usage has been updated with performance and UI improvements.
- We fixed issues preventing Insiders from adding cards to Wallet and paying using tap to pay.
- We fixed an issue resulting in being unexpectedly able to close Start in the task switcher.
- We fixed an issue resulting in certain options for default calling app via Settings > System > Phone > Default apps from being unexpectedly missing.
- We fixed an issue causing apps that play media in the background, such as Groove Music, to stop when Battery Saver turns on.
- We fixed an issue Insiders may have experienced where the phone would get into a state where copy/paste wouldn't work until the device had been restarted.
- We fixed an issue where Settings might hang after unchecking "Let apps automatically use this VPN connection" in VPN Settings.
Known issues for PC
- If you have a 3rd party antivirus product installed on your PC – your PC might not be able to complete the update to this build and roll-back to the previous build.
- We're aware of an issue where Internet Explorer may crash a few seconds after launch and working.
Known issues for Mobile
- If you used the previous 'date change' workaround to update to Build 14951 or Build 14955: Please don't use it any longer! The Microsoft account (MSA) ticket on your device needs to expire and then you'll be offered today's build. If you changed your date by 30 years… you'll want to do a device reset.
- You will be unable to install additional languages, keyboards, and speech packs on your phone for the next few weeks. If you have existing languages, keyboards, and speech packs installed – they will carry over when you update to new builds. You just can't install any new ones. If you do a hard reset of your phone on these builds – you will also be unable to install additional languages, keyboards, and speech packs. You can use Windows Device Recovery Tool to go back to Windows Phone 8.1 or Windows 10 Mobile, install any languages, keyboards, and speech packs you need and then update to the latest build in the Fast ring as a workaround, Microsoft explained.
Microsoft extended by 18 months its end-of-life date for its Enhanced Mitigation Experience Toolkit (EMET) to July 2018.
Microsoft officials noted that the first version of EMET was introduced in 2009, back then, "despite substantial improvements in Windows OS security during that same period, it was clear that the way we shipped Windows at the time (3-4 years between major releases) was simply too slow to respond quickly to emerging threats. Our commercial customers were particularly exposed since it often took years to deploy new OS versions in large scale environments," said Microsoft.
