Microsoft has just started to roll out Windows 10 Redstone 4 Insider Preview Build 17110 to Windows Insiders in the Fast ring. Today's update is the second one from this branch that is focused almost completely on bug fixes instead of new features. However, it does bring some improvements for Enterprise customers in Redstone 4. Here's the complete changelog.

What's new in Windows 10 Redstone 4 17110

Enterprises can now run custom actions during feature update: In RS4, we are adding a new feature that will enable your enterprise to run your own custom actions/scripts synchronously with setup. Setup will execute custom actions during two update phases controlled by using preinstall.cmd or precommit.cmd:

  • Pre-install: This would be just before all the system and device compatibility scans run.
  • Pre-commit: This would be just before the system reboots into the offline phase.

Setup also migrates the scripts for future updates. In the event of an update failure or rollback, a failure.cmd script can be used to perform custom operations or undo actions of previous custom scripts.

Run (Migrate):

  • C:\Windows\System32\update\run\<GUID>\preinstall.cmd
  • C:\Windows\System32\update\run\<GUID>\precommit.cmd
  • C:\Windows\System32\update\run\<GUID>\failure.cmd
  • C:\Windows\System32\update\run\<GUID>\reflectdrivers\foo.inf
  • C:\Windows\System32\update\run\<GUID>\reflectdrivers\foo.sys

Run Once (Do not migrate):

  • C:\Windows\System32\update\runonce\<GUID>\preinstall.cmd
  • C:\Windows\System32\update\runonce\<GUID>\precommit.cmd
  • C:\Windows\System32\update\runonce\<GUID>\failure.cmd
  • C:\Windows\System32\update\runonce\<GUID>\reflectdrivers\bar.inf
  • C:\Windows\System32\update\runonce\<GUID>\reflectdrivers\bar.sys

Enterprises can run post rollback scripts in system context​: Current /postrollback scripts run if the first user logs in after the rollback has admin privileges. We received feedback from several enterprises that most of their employees don’t have admin privileges. With RS4, we are enabling /postrollback scripts to run in admin context or system context.

We are not changing the behavior of the existing /postrollback switch. We have added a new switch /postrollbackcontext “xxx” to be used along with /postrollback switch to specify in which context should the scripts be executed:

  • To run /postrollback scripts in system context

–        setup.exe /postrollback c:\Fabrikam\setuprollback.cmd /postrollbackcontext system

  • To run /postrollback scripts with first user to login have admin privileges (admin context)

–        setup.exe /postrollback c:\Fabrikam\setuprollback.cmd /postrollbackcontext admin

Windows containers

Docker for Windows users, we are flighting the matching Windows container images of Server Core and Nano Server to the Docker Hub for continued testing and feedback.  Thank you for all the great feedback and please keep it coming!

Today's release also continues to fix a number of issues, including several Green Screen of Death problems, Cortana troubles, and Game Bar issues. You can check them out over at Microsoft. Windows 10 Redstone 4 Build 17110 also brings a handful of known issues, including:

  • Selecting a notification after taking a screenshot or game clip opens the Xbox app’s home screen instead of opening the screenshot or game clip.
  • Post-install at the first user-prompted reboot or shutdown, a small number of devices have experienced a scenario wherein the OS fails to load properly and may enter a reboot loop state. For affected PCs, turning off fast boot may bypass the issue. If not, it is necessary to create a bootable ISO from an ISO on a USB drive, boot into recovery mode, and this will allow bypass.
  • When Movies & TV user denies access to its videos library (through the “Let Movies & TV access your videos library?” popup window or through Windows privacy settings), Movies & TV crashes when the user navigates to the “Personal” tab.
