The default capture function in MDT does not add any description. It is not needed, but can be added by modifying ZTIBackup.wsf. In this case I added the Task Sequence Name, but you can add other things as will, like Task Sequence Description or Task Sequence version. I did this at a demo at Microsoft Ignite last week but I did not post it at that time, so here it is.

The Session from Ignite is here if you would like to see it: https://www.youtube.com/watch?v=H9HGSVEaqQk

The how:

Modifying the Script

Take a copy of ZTIBackup.wsf, open it in your favorite VBscript editor and look for this section:

At line 436 you will see this:

sCmd = " /Capture-Image /CaptureDir:" & oDrive.Path & "  /ImageFile:""" & sBackupPath & """  /Name:""" & sPrefix & Left(oDrive.Path, 1) & "Drive"" /Compress:MAX /ConfigFile:""" & sWimScriptPath & """ /ScratchDir:""" & oUtility.LocalRootPath & "\Scratch"""

Change that to:

sCmd = " /Capture-Image /Description:""" & oEnvironment.Item("TaskSequenceName") & """ /CaptureDir:" & oDrive.Path & "  /ImageFile:""" & sBackupPath & """  /Name:""" & sPrefix & Left(oDrive.Path, 1) & "Drive"" /Compress:MAX /ConfigFile:""" & sWimScriptPath & """ /ScratchDir:""" & oUtility.LocalRootPath & "\Scratch"""

(The yellow text shows the modification)

The result:

Using Get-WindowsImage will show you that the description is now set to the Task Sequence name:

If you import the WIM file into ConfigMgr you will also see the description set as well as the Comment:
