Changelog for Windows 10 Insider Preview 14388 for PC and Phone

Rolling out to the Fast Ring for Windows Insiders, the new update for PCs and Phones on the Redstone branch has a build number 14388. According to the head of the Insider Program, Dona Sarkar, this build includes 44 fixes and improvements. Here are the most significant improvements and known issues:

Improvements for Phones:

• We have updated the Store to version 11606.1001.39 with bug fixes.
• We fixed the issue causing the keyboard to not show up consistently for InPrivate mode on Microsoft Edge.
• We fixed an issue that could result in an app getting into a state after being suspended where it would be unable to launch until rebooting the device.

Known issues for phones:

• Voice Recorder does not show up consistently as an option for Call Recording. We heard your feedback and plan to release a Voice Recorder app update via the Store soon that has the fix for this issue.
• 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.
• 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.

Improvements for PCs:

• We have updated the Store to version 11606.1001.39 with bug fixes.
• We fixed an issue where Narrator keyboard shortcuts would not work after locking your PC and then logging back in and going to your desktop.
• We fixed an issue where Narrator would not read the date and time under Settings > Time & language > Date & time.
• We fixed a TPM driver crash that could result in the device bug-checking (bluescreen) and rebooting.

Issues for PCs:

• A recent fix went into place for the Hyper-V firmware that will that affect the ability to boot Windows Server 2016 Tech Preview 5 VMs with Secure Boot enabled. A fix for TP5 builds has been developed however, due to release schedules, the Insider Preview build changes will be released before the TP5 fix is released. During that time, if you try to boot a new TP5 VM with Secure Boot enabled, it will fail. The workaround is to disable Secure Boot during this period.
• After you install this build on a PC using a non-EN-US language, you may get error code 0x80004005 when enabling Developer Mode on the “For Developers” Settings Page. Even after seeing this error message, your machine is in developer mode and you should still be able to use Visual Studio to develop Universal Windows Applications. In most cases, this error indicates that extra components required by the operating system to enable additional debugging features in Visual Studio or the Windows Device Portal could not be installed automatically.

  To fix this:

  #1. Go to Settings > System.
  #2. Click on “Apps & features”
  #3. Choose “Manage Optional features”
  #4. Press the button “Add a feature”
  #5. Select the package for Windows Developer Mode
  #6. Click “Install”
  #7. Reboot your PC
  #8. Launch Command Prompt as Administrator
  #9. Run: sc config debugregsvc start=auto

• Finally, return to the “For Developers” Settings page. You will still see the error code, 0x80004005 but you should now be able to enable Windows Device Portal and the Device Discovery features.

Microsoft also announced that the Windows Insiders will be able to install the official Anniversary Update build before August 2, which means the RTM build could be available for testing in the next two weeks.
