DISM Servicing Script

This was born of my need to remove OneDrive from annoying everyone into installing it.  My client will soon be turning on OneDrive for Business, so the default OneDrive needed to be removed from the image.  I also found that I couldn't install one of their pieces of financial software because .NET 3.5 was not enabled and, though I could just enable it with a one-liner in the task sequence, I thought it would be nice if their image just had that turned on.  I also thought that it would be nice to have CMTrace.exe available on every PC in my environment.

Finally (and the part the prompted me into actually scripting the whole thing) I found it annoyingly difficult to change the default user's theme, including the lock screen, without a GPO.  The issue is that Trusted Installer service protects the area where the themes are stored, so if the machine is online you have to take ownership of the files which subverts the Trusted Installer.  I wanted to have my theme work but also have Trusted Installer work.  You can do this with SysPrep but I decided to do some offline manipulation of the image because I wanted to practice my "DISM-FU".

So, here it is.  The script mounts the WIM, enables .NET 3.5, copies in the wallpaper and .theme files for the theme, sets a registry item in HKU\.default's RunOnce to run the theme thus setting it active on a user's first logon, sets the lock screen registry items, and finally rips out OneDriveSetup.exe itself and the call to run it from HKU\.default.

SourceWIM = the location of your WIM file that you want to edit
FeaturesSource = the "sources" folder from your original Windows 10 media
WallpaperSource = the network location where you have stored the wallpaper you want to use
LockScreenSource = the file name within WallpaperSource to use as the lock screen
CMTraceSource = network location of CMTrace to copy into the WIM
LogFile = Where you would like this script to spit out its log file

I often comment out the unmount line at the end so that I can make adjustments if I want to after the .bat file runs.

Here it is, enjoy
