Enabling Dynamic Update AND Ignoring Dissmissable Compatibility Warnings during an Windows 10 In-Place Upgrade Task Sequence in ConfigMgr

If you haven’t already, check out Part 1 Here, otherwise this won’t make as much sense.

In all of the haze of my attempts to get out to Windows Update, I lost sight of my ultimate goal, which was to be able to go out to Windows Update AND ignore dismissible compatibility warnings when using the Upgrade Operating System step in a ConfigMgr Task Sequence. While I was researching this issue, I had run across the Task Sequence option OSDSetupAdditionalUpgradeOptions as documented here. Johan (@jarwidmark) has a good write-up on that here. It was late as I was finishing up testing, so I just made a note to look into it because I wanted to use the /DiagnosticPrompt enable Windows Setup command line option for testing in my Task Sequence.

As I got back into the office and started testing, I realized that I wasn’t done. If you have ever checked all 3 boxes,

All 3 Boxes

you will have seen the message in the smsts.log stating that the Ignore flag was being Ignored:

Ignoring the Ignore

Now that we know the secret behind getting past ConfigMgr and out to Windows Update, we don’t need to check the boxes. In fact, we can bypass MOST of the checkboxes (Time-Out is a ConfigMgr option, so if you need it, check the box). We can just use OSDSetupAdditionalUpgradeOptions to add any command line options that we want. Technically, you could just run it all from a Run Command Line step instead of using the Upgrade Operating System step, however, there is some behind-the-scenes integration that makes it worth keeping around.

Quick Tangent about the Upgrade Operating System step. Open Task Manager and you will see OSDUpgradeOS.exe running during the Upgrade Operating System step.


This step manages the Task Sequence and Windows Setup integration. It adds the SetupComplete.cmd and SetupRollBack.cmd files and manages the Task Sequence UI between reboots. So, don’t dismiss this step, maybe just don’t use the check boxes.

Speaking of check boxes, the Task Sequence knows what boxes you checked, but doesn’t check the OSDSetupAdditionalUpgradeOptions variable to see what you added there. Can you guess where I’m headed with this?? Just move the items from the check box to the OSDSetupAdditionalUpgradeOptions variable and you the Task Sequence ignores the ignore but in a good way this time!

The Hack v2.0

Update you Task Sequence from my previous post, to be more like this:

Type: Group
Name: Upgrade the Operating System

Type: Run Command Line Step
Name: Rename Registry.pol
Command Line:

Type: Run Command Line Step
Name: DELETE WindowsUpdate Key
Command Line:

*You can get fancy and rename this key then rename it back at the end, but you get the point. We just don’t want this key for now.

Type: Run Command Line Step
Name: Restart Windows Update Service
Command Line:

Type: Set Task Sequence Variable
Name: Set OSDSetupAdditionalUpgradeOptions
Task Sequence Variable:

Refer to Windows Setup Command Line Options for additional options.

Type: Upgrade Operating System
Name: Upgrade Operating System
Select your Upgrade media and Don’t Check ANYTHING!!
See The bottom of this post for more info

Upgrade Operating System

Type: Group
Name: Cleanup

Type: Run Command Line Step
Name: Rename Registry.pol
Command Line:

*Note: At this point, your machine is still pointed to Windows Update, so you will need to gpupdate /force to have it regenerated. I haven’t tested this far yet, but I would assume by the end of the Task Sequence, the machine will have updated policies and rebuilt the key.

The end result should look something like this if you started with my previous Task Sequence and just commented out the steps:

Updated Hacked TS!!
