Windows 10 Insider Preview Build 14393 for PC and Mobile arrives on the Fast ring

Windows 10 Insider builds really are coming thick and fast now. Build 14390 came out just three days ago, and now we have Build 14393 following it on to the Fast ring.

This pattern will continue for a while yet as Microsoft squashes as many bugs as possible as it enters the home stretch for the big Anniversary Update out on August 2.

As you’d expect, there are no new features in this build, just fixes and improvements. For PC these include:

• Microsoft has improved the reliability of Start, Cortana, and Action Center.
• You should now be able to mount iPods as USB mass-storage devices.

For Mobile, the updates include:

• Microsoft has fixed an issue resulting in rapid battery drain when Visual Voicemail syncs voicemail messages on Dual SIM devices like the Lumia 950 XL.
• It also fixed an issue causing some battery drain on older devices like the Lumia 535, 640, 735, 830, 930 and Icon.
• 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.
• Fixed several issues impacting Dual SIM capabilities. Using a device with two SIMs should work as it should.

There are still some known issues to be aware of. For PC:

• Microsoft is 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.

For Mobile:

• Microsoft is 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 the 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.
• REMINDER: Microsoft has 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.
