Mount-OSDWindowsImage is based off of Mount-WindowsImage. So why the need for a new function? Here's a few reasons
I can't just specify a WIM
I have to specify an Index
My Path (Mount Directory) needs to exist
For starters, all you need to provide is a WIM (Position 0). There is no need to specify an Index as Index 1 is assumed if one is not provided.
The WIM is mounted to a Random directory in $env:TEMP. This directory is automatically created
Mount and Explore
And finally, the Explorer parameter will automatically open Windows Explorer to the Mount Path
Finally this is the gem for those of you that Hate OSDBuilder. You will need an up to date OSDSUS for this to work properly
Windows Image Mount Path Is Optional
Yes Boys and Girls, this is quite a treat. Simply run the function without any Parameters. If you have a Mounted Windows Image, it will find it ... and let you know if it needs any updates
Multiple Windows Images - Mounted
Ok, did I just mount three WIMS in a single command line? Ok, now I'm just showing off ... but as you can see, Update-OSDWindowsImage will find all three and give me an update
Multiple Windows Images - Mount | Update | Dismount
If you thought that was it ... yes you can use this in the Pipeline
OK, I think you get the idea of the different ways you can use it ... so let's focus on the Updates. You can use these Update values
And there's even a BitsTransfer parameter too!
So here is your PowerShell One-Liner to Mount, Identify the OS, Identify the Required Updates, Download the Updates, Apply the Updates, and finally, Dismount and Save an Install.wim. This by far makes the shortest WIM Update script ever. Enjoy!
Mount-OSDWindowsImage T:\WimOS\install.wim | Update-OSDWindowsImage -Update All | Dismount-WindowsImage -Save
Or you can Script the solution for better readability
Downloads and Logs
If you need the Downloads and Logs (you know how I am about Log files), simply look in $env:TEMP\OSD
OSD Helper Functions
Finally some other functions from the OSD Module were used to make this all work
