Microsoft seeds cumulative update 14393.5 to public testers

Windows 10 Mobile and PC Desktop

New update for the RTM build

Microsoft is rolling out a new cumulative update 14393.5 to Insiders on the Fast Ring. This update brings further improvements and fixes for both PC and mobile, in a preparation for the Anniversary Update whose roll out should begin on August 2.

Build 14393.5 includes the following improvements:

We have improved reliability and performance of Microsoft Edge with AdBlock and LastPass extensions enabled. These extensions should continue to work after installing other extension updates from the Store.

  • We fixed an issue causing battery to drain due to runaway CPU processes while a device is idle. We also fixed a battery life issue due to the proximity sensor always running on some devices.
  • We fixed an issue causing Store apps to stop launching due to a licensing issue.
  • We have fixed an issue that results in Windows Updates being delayed on systems with Connected Standby.
  • We fixed an issue where the Korean IME would not have the correct composition on some custom TSF3 edit controls on PC.
  • We fixed an issue where you might not be able to type in text into Search or some Store apps without having to restart the process.
  • We have fixed an issue where keyboard input on some Windows tablet devices would not rotate to landscape normally.

If everything with this build is fine, it should successively reach Insider Slow, Release Preview and finally all Production devices eligible for the Windows 10 Anniversary Update.
