Announcing Windows 10 Insider Preview Build 17672

Hello Windows Insiders!

Today, we are releasing Windows 10 Insider Preview Build 17672 (RS5) to Windows Insiders in the Fast ring in addition to those who opted in to Skip Ahead.

Microsoft Build 2018 Recap

We’re still reeling from how awesome the Microsoft Build conference was this year. Our team and our friends from Deployment, Feedback and Flighting manned Windows Insider booth all 3 days and circulated through the conference learning all the cool new tech. We had over 800 people come by our booth and we had the opportunity to share what’s next for the program AND learn what we can be doing better to create a better Insider program.

We also had the pleasure of having three of our most passionate Insiders as our guests.

Ange Uwambajimana, Irving Amukasa and Raymond Dillion were chosen to attend the conference and present on stage with us because of their impactful work using technologies in their local communities. Ange has created an IOT IV Drip solution to account for the lack of enough nurses in her home country of Rwanda who look after patients who are re-receiving. Her story is based on a near-tragedy involving her brother who suffers from epilepsy. Irving has created SophieBot, a “Cortana for reproductive health questions” to account for the fact that in many parts of the world, talking about sexual and reproductive health is taboo. Raymond is working to digitally transform Ireland, get them out of the paper records business AND grow the next generation of tech enthusiasts.

These Insiders had a chance to meet many of our upper management, including Satya! Satya asked them quite a few detailed questions about how they were using our tech, what more we could do to make it easier to use. The best moment was when THEY started asking Satya some hard questions about AI. Each of the Insiders walked away with homework too.

We had three sessions talking about the benefits of being an Insider and a developer.

Insiders <3 Enterprise Apps where we talked about WIP and Windows Analytics are a natural fit. No longer do enterprise devs need to test their applications against the most compatible version of Windows ever. Instead, they can use the AWESOME tools that Microsoft has provided including Windows Analytics and Windows Desktop Application Program. Here’s how anyone can use Device Health from Windows Analytics to make sure their applications will be ready for RS5. Watch the session here.
If (dev) { Insider();} where we showcased how any Windows app dev can run their own Insider program using:
- Cohorts as a Service where any Windows app dev can set up their own private cohort on our Insider forums to talk directly with their customers who are Insiders. We showcased this using our friends at Collaboard as the example.
- Flighting your app with experiments and using the Feedback Hub from your app.
- Watch the session here.

Turning Good Code into a Great Business where our three Insiders shared their stories AND we unveiled the opportunity for any dev (or aspiring dev) Insider seeking career advice to sign up for the new private Code to Biz forum where you can get advice from our three featured Insiders, Insiders from all over the world AND our team on how to create a successful business with your code. Watch the session here.

MANY Insiders have said they would love to see the best of Microsoft Build AND meet our team, so we’re making it happen. In partnership with the Developer Marketing and the Partner App Experience teams, we also announced the upcoming month-long Insider Dev Tour where we will be showcasing the best of Microsoft Build on the road in over 20 cities. In many of these cities, we’ll be doing a pre-event mixer to meet as many of you as possible. Join us!

What’s new in Build 17672

Windows Security Improvements

The Windows Security Center (WSC) service now requires antivirus products to run as a protected process to register. Products that have not yet implemented this will not appear in the Windows Security UI, and Windows Defender Antivirus will remain enabled side-by-side with these products.

For testing purposes, you can disable this new behavior in Windows Insider builds by creating the following registry key and rebooting the device. This key will be removed as we get closer to release.

General changes, improvements, and fixes for PC

We fixed an issue where right-clicking to copy text in Microsoft Edge didn’t work in recent flights.
We fixed an issue with structuredquery.dll resulting some users experiencing a cyclical explorer.exe crash.
We fixed an issue resulting in the two-finger gesture to dismiss all notifications not working in the Action Center.
We fixed an issue resulting in the Korean IME sometimes entering duplicate characters when typing into text fields in certain websites in Microsoft Edge.
You can now refresh the Books pane in Microsoft Edge using a pull gesture.
When you pin books to Start from Microsoft Edge you will now see a live tile that cycles between the book cover and your current completion progress.
When printing PDFs from Microsoft Edge, you’ll find a new option to choose the scale of your print out (Actual size, or Fit to page).
We’ve updated Timeline so that in addition to seeing the number of available tabs to restore associated with a particular Sets activity, you can now cycle through them.
We’ve made some adjustments to improve the quality of audio when recording clips using the game bar (WIN+G). Thanks, everyone who shared feedback about this – please take a moment to try it out in today’s build and let us know how it goes.
We fixed an issue that could result in apps sometimes not fully maximizing to the top of the screen.
We fixed an issue resulting in certain devices not being able to wake from sleep in the last two flights (just showed a black screen).
When you hover over the leaf icon in Task Manager’s Status column, you will now see a tooltip describing what it means (this app is suspending processes to help improve system performance).
Building on our work from Build 17639, in addition to showing Bluetooth battery level in Settings for supported devices, you will now see a notification when one of those devices is low on battery.
For our WSL fans out there: if you’ve enabled WSL, you’ll now see an option to “Open Linux Shell here” when you Shift + Right-click on the whitespace of a File Explorer folder.
We’ve introduced preview support for same-site cookies in Microsoft Edge and Internet Explorer 11.

Known issues

After completing the Windows Mixed Reality First Run experience, OOBE is black. Motion Controllers are also not recognized in exclusive apps. If you need your Mixed Reality experience to be working it is advised you not take this build until these issues are fixed.
We’re aware of an issue that causes Narrator to read extra text when invoking Alt + Tab, and we’re working on a fix.
If you complete the setup for a Windows Mixed Reality headset on this build, the headset will remain black until it is unplugged and reconnected to the PC.
We’re making progress on our work to support dark theme in File Explorer and the Common File Dialog, and you’ll see improvements in this build, but we still have some work to do.
Insiders who use Remote Desktop, project their screen, or have multiple monitors may experience explorer.exe hangs on this build. This issue can also lead to Microsoft Edge hangs.

Known issues for Sets & Office

Sets UX for Office Win32 desktop apps is not final. The experience will be refined over time based on feedback.
The top of some Win32 desktop app windows may appear slightly underneath the tab bar when created maximized. To work around the issue, restore and re-maximize the window.
Closing one tab may sometimes minimize the entire set.
Tiling and cascading windows, including features like “View Side by Side” in Word, will not work for inactive tabs.
The Office Visual Basic Editor window will currently be tabbed but is not intended to be in the future.
Opening an Office document while the same app has an existing document open may cause an unintended switch to the last active document. This will also happen when closing a sheet in Excel while other sheets remain open.
Local files or non-Microsoft cloud files will not be automatically restored, and no error message will be provided to alert the user to that fact.
