Windows 10 update KB4103721 (build 17134.48) releases

If you're running the Windows 10 April 2018 Update, a new update is rolling out to address some of the issues with the version.

As part of Patch Tuesday for May 2018, Microsoft is now rolling out update KB4103721 for devices running the Windows 10 April 2018 Update (version 1803) to address a few issues with the latest release.

KB4103721 bumps the build number to 17134.48, and according to the company, it only addresses a few issues related to App-V, VPN, time zone, Remote Desktop, and patches some security vulnerabilities.

Unfortunately, the update doesn’t make any mention that the update fixes recently reported problems, such as the freezing issue with Google Chrome and Cortana, or graphics problems with certain Dell computers.

Alongside this update, KB4103727 is also rolling out for Windows 10 Fall Creators Update fixing several problems with that version.
