[BUG] Unsupported Image Build [19042]

[ghysler]

After running Start-Optimize.ps1 from an elevated PowerShell the following message returns:

Copying WIM from "S:\W10UI\DVD\sources"
WARNING: Unsupported Image Build: [19042]

• Image Name: Windows 10 Pro
• Image Build: 19042
• Host Environment: Windows 10 Pro

Integrated 2020-10 updates into image from official 20H2 ISO with W10UI first, including Enablement Package (20H2). According to the changelog build 19042 should be supported. What am I missing here?

This is by no means a final solution but a workaround that worked for me. Open Optimize-Offline.psm1 in your favorite text editor and go down to about line 240:

	If ($InstallInfo.Build -ge '17134' -and $InstallInfo.Build -le '19041')

Just remove the latter half and make it read:

	If ($InstallInfo.Build -ge '17134')

Or, if you're paranoid, comment out the above top line and make a copy of the bottom line, like this:

#		If ($InstallInfo.Build -ge '17134' -and $InstallInfo.Build -le '19041')
		If ($InstallInfo.Build -ge '17134')

(final edit) Or, just change 19041 to 19042.

Save and launch O-O again.

Thanks @strotee, that works like a charm as a workaround.
