Perhaps another thread for this? How to change Khyi's PE disk
Anyway from what I can figure out (silence - I kill you) creating a shortcut isn't enough. I tried it (adding them to Public or Default desktop) and it didn't work.
What you can do though (after changing the programs) is update F:\mount\Windows\system32\Win10PE.cfg to add the new shortcuts (and remove the old ones).
I've no idea of the structure of this file or what it does exactly (except it seems to run when the image boots up) but copying the structure of what is there seems to work. For example if you want to change "FireFox" to "Palemoon" just search/replace.
If you don't want CCleaner delete all references to it.
If you want to add a new program add the lines
As long as the program is portable it seems to work.
HD Tasks\MBR|Whatever|X:\Program Files\Whatever\Whatever.exe||
As for printing I don't own one and still go to the internet café if I really have to print or fax something so I can't help with that. Load your Wi-Fi or Printer driver I suppose.
Set your timezone if you like
Add-WindowsDriver -Path "F:\mount" -Driver "<directory containing the inf files>" -recurse
and there you are - his PE disk as you like it
& (gcm "dism.exe") @("/image:F\mount",'/Set-TimeZone:Romance Standard Time')
I did try for a long time to make my own from scratch but it was all to complicated for me. I couldn't get any type of GUI to work - only a limited file explorer.
Much easier to tweek an existing one so it is as you like it (there is a lot of background work done here I think).
