customize WinPE

Initially, backup or rename the WinPE images located under the LANDesk directory in Program Files. Optionally, these images can be replaced, though it’s not advised. Then, transfer clean images from the clean sub-folder to the main vboot directory. Execute OSD.Upgrade.exe as administrator to finalize the WinPE setup by adding necessary drivers and customizations, as outlined in Ivanti EPM documentation.
