Microsoft begins the rollout of the cumulative update KB4015583 for the PCs running the Windows 10 Creators Update (version 1703). The new update doesn’t bring new features, but it does addresses a few problems found in the newly released OS.

KB4015583 bumps the version of Windows 10 to build 15063.138, and delivers fixes for time related issues, and security updates for various features, including .NET Framework, Microsoft Edge, and Windows kernel-mode drivers.

What’s new on Windows 10 build 15063.138

Microsoft has announced KB4015583 in its support site, and it’s referred as “April 11, 2017—KB4015583 (OS Build 15063.138)”, and if you’re running version 1607, this update will install version 1703 on your system.

If you’re already running the Windows 10 Creators Update, this update will only address two issues with OS, including:

  • Fixed issues with updated timezone information.
  • Security updates to Scripting Engine, libjpeg image-processing library, Hyper-V, Windows kernel-mode drivers, Adobe Type Manager Font Driver, Internet Explorer, Graphics Component, Active Directory Federation Services, .NET Framework, Lightweight Directory Access Protocol, Microsoft Edge and Windows OLE.

Microsoft also notes that if your device was enrolled in the Fast ring, and then you changed the level to Slow or Release Preview, then you may get an error 0x80073715. However, it’s an expected error, as the company has released the update to the public with a different reference number, but it’s nothing that you should have to worry.
