Unknown, Thanks for putting down the steps to get the WinPE with the Explorers (Windows and Internet) enabled. I followed the steps and came up with the ISO size of 275 MB and not 360 as you have mentioned. Then when I booted the image that created - I get an error - mpio.sys file is missing. Right now I am going to add this file, I have tried a similar exercise before and got to a position where after adding crcdisk.sys - the WinPE image would just start rebooting. Do we have to cppy some drivers also from the install\windows\system32\drivers folder to the \test\windows\system32 folder including the inf files? Also, in the step for the registry - you mention copying the SYSTEM hive under install\windows\system32\config and not the SOFTWARE hive - however in the editing steps you mention editing \HKLM\Soft\Microsoft\Windows\CurrentVersion\Control Panel key which resides in SOFTWARE hive. Thanks, Rohit
