@smurawski I didn't find any downloadable links for this updates. But we can get them via Get-Hotfix cmdlet. For example

Get-HotFix -ID KB3119938

https://raw.githubusercontent.com/PowerShell/SILDeploymentHelper/431dc8e6a0a566ac4a7a301caa121d6fc42ab002/SILDeploymentHelper.psm1

Also we can move geeting hotfixes to separate library helper.

Closing this due to age - for most people this patch would now be applied in any image, and WMF 5 is the recommendation anyway.
