Microsoft today released Windows 10 RS4 Build 17110 for Insiders in the Fast ring. This build does not include any new features for consumers, but it does include some new features for enterprise customers. Read about them below.
Support for custom actions during feature update:
With this build, enterprise can run their 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.
Support for post rollback scripts in system context?:
Current /postrollback scripts run if the first user logs in after the rollback has admin privileges. Starting with this RS4 build, Microsoft is enabling /postrollback scripts to run in admin context or system context. They are not changing the behavior of the existing /postrollback switch.
