UPDATE 7/20: We have released Windows 10 Insider Preview Build 14393 to Windows Insiders in the Slow ring.

Hello my Windows Insiders!

I hope everyone had an awesome weekend. Many of you know that helping people learn tech is a deep passion of mine so I spent some time working on some UWP app ideas that the we can do with you all, both in-person and online. We are always looking to learn new things (such as IoT development) and what better way that alongside all of you. I’ll share some videos of the progress we make.

In build news, today we are releasing Build 14393 for both PC and Mobile to Windows Insiders in the Fast ring. This build includes a handful of new fixes to take note of:

Improvements and fixes for PC

We have improved the reliability of Start, Cortana, and Action Center.

You should now be able to mount iPods as USB mass-storage devices.

Improvements and fixes for Mobile

We fixed an issue resulting in rapid battery drain when Visual Voicemail syncs voicemail messages on Dual SIM devices like the Lumia 950 XL.

We also fixed an issue causing some battery drain on older devices like the Lumia 535, 640, 735, 830, 930 and Icon.

We fixed the issue causing Voice Recorder to not show up consistently as an option for Call Recording. A app update was released last Friday that fixes this issue. Make sure you have the app version 10.1607.1931.0.

We fixed several issues impacting Dual SIM capabilities. Using a device with two SIMs should work as it should.

Known issues for PC

We are aware of certain cases in which Surface Books and Surface Pro 4’s may bugcheck (bluescreen) due to a camera driver issue. An updated driver will roll-out via Windows Update soon that will fix this. After updating to this build (Build 14393), you should no longer experience bugchecks (bluescreens) due to a camera driver issue. The bad driver is removed on updating to this build and a new driver is rolling out via Windows Update.

Known issues for Mobile

We are continuing to investigate W-Fi issues on certain devices.

Turning off Bluetooth can sometimes result in freeze, crash, or reset. See this forum post for more details.

Wallet users are prompted for a PIN twice when using tap to pay from a locked phone. You can enter their PIN twice and tap as usual once the phone is unlocked. A fix for this will come as a Wallet app update via the Store. UPDATE 7/19: An updated version of the Wallet app is going out via the Store with the fix to this issue.

REMINDER: We have changed the backup format for Windows 10 Mobile devices to reduce the size of the backup stored in OneDrive. As a result, if you do a backup on a device running the latest Windows 10 Mobile Insider Preview builds and move back to the released version of Windows 10 Mobile (Build 10586) and restore from your backup – your Start screen layout won’t restore and remain the default Start layout. Your previous backup also gets overwritten. If you need to go back to Build 10586 temporarily, once you are on Build 10586 you should disable backup so it doesn’t overwrite the good backup from Windows 10 Mobile Insider Preview builds. We will stop noting this going forward.

All right, that’s all for now. Have an excellent week, team.

Keep hustling,
