OK, because I don’t have time to explain everything right now, but I know some people are eager to play with what they saw at MMS… here is the download.
For Documentation, please continue to monitor the "WaaS" Page which I will continue to update with links as I blog each module.
19 Task Sequences, Several packages.. it’s here…WaaS 1809 TS Collection v2019.05.22 (525 downloads)
I’ll be slowly posting information about this, which a deeper dive about the task sequences and how they work.
- Pre-Cache Compat Scan TS: This is the TS that you’d run first to get the content downloaded, and pull back information about the Compatibility Scan.
- In Place Upgrade TS: This TS runs the actual Upgrade. It also adds several nested TSs to do various tasks, including setup Rollback & OS Uninstall protections.
- OS Uninstall TS: This TS allows you to go back to previous version of Windows 10. It requires that you have done pre-work in the down level OS to make this work, which is already built into the OS Upgrade TS I’m supplying.. Blog: WaaS IPU – OSUninstall Module
- DeBug Mode TS: This is used for troubleshooting your Task Sequences… Blog: Building a Better Debug Task Sequence
- Pre-Assessment & PreFlight Baseline & CIs... Blog: WaaS PreAssessment & PreFlight using Config Items
Major Changes from the last WaaS Task sequences I’ve posted
- No longer using “SetOSDInfo” Script, now just writing information to the registry along the way, which then gets grabbed by hardware inventory. I’ll try to blog this as well eventually.
- Heavy use of Sub Task Sequences
- Rollback Recovery / OS Uninstall
- Splash Screen and other End User Experience enhancements.
- Baseline Cab to import (Required for the PreFlight)
- PRE-REQS: CM 1902 Client on Machine running IPU
Ok, I’m sure you’ll have a lot of questions.. however I’ll try to answer them when I get time. I’ll be slowly working on detailed information to blog about the process and task sequences, just might be awhile.
YouTube Demo Videos:
- PreFlight Failure of Execution Rule (Low Disk Space)
- PreFlight Failure of “Internal Hard Blocker”, then Retry and Full Upgrade Process
- OS Uninstall Process
So, now that all makes sense. Here is a list of the Nested Task Sequences called during the upgrade process.
- Splash Screen - Blogged: Windows Splash Screen for the Task Sequence Progress
- PreFlights. - Blogged: WaaS PreAssessment & PreFlight using Config Items
- Execution and Internal Hard Blocker check
- CleanUp - Blogged: Clean Up Storage Pre Upgrade
- Triggered if less than 20GB free then runs random tasks to free up space
- Lock Screen Pre: Windows 10 Lock Screen
- Recovery Rollback Pre: WaaS IPU - Rollback Recovery Module
- OS Uninstall Pre: WaaS IPU – OSUninstall Module
- Driver Variables: WaaS IPU - Rollback Recovery Module
- Download Driver Package
- Pre Upgrade
- Post Upgrade
- Post Upgrade Build #
- Win 10 Customizations
- Lots of tweaks and mods to brand your machine
- Lock Screen Post
- OS Uninstall Post
- Recovery Rollback Post
- Legal Text
So that's a VERY HIGH Level of the WaaS IPU Task Sequence and all the Nested Task Sequences called during the process.
