Yesterday I sat down and dissected the MS way to implement WMI into PE 2005 (1.6) in order to add it to my XP LiveCD. It did not seem to be all that complicated so I made a WinBuilder script that does the same thing as what the MS OPK's MKIMG.CMD does and ended up with two .REG files, lean, clean and not so overly large. Together with the pre-built repository from the OPK it all came down to a script of about 900KB.
The script builds without error in WinBuilder (XP LiveCD) and upon boot the WMI services are available and started without errors. I have not yet had any chance to determine whether WMI is 100% working, but the same files and registry settings that the MS PE 2005 uses are copied and implemented.
Enclosed you will find the script, if this is the wrong place for the upload then please advice me where to upload scripts.
Have fun!
(BTW, the files for Event Viewer are also copied, but it does not work (yet!))
