if u can enter sysprep, at beginning of oobe, then you should have no problem using windows update to install all hotfixes, drivers, etc, depending on your need s . and then generalize, and capture. For example; I find it alot quicker when integrating vista sp2 to 1st intsall vista sp1 on second partition. 2nd enter sysprep on oobe. 3rd connect to internet. 4th install windows installer 4.5 5th run window update. (for vista i only install OS updates, but win 7, if possible you can also install your drivers via windows update) 6th finally after all updates and reboots are complete i install SP2 RC1 or whatever. on reboot i run compcln.exe. and using sysprep, i generalize and shut down. boot in my case xp, then i run 3rd party disk clean up and disk defragmenter, to remove install log files temp files etc etc. finally capture a nice sp2 v.113, v.286 yadda yadda. then use vlite to customite into a nice complete iso. works fine. and is faster than integrating using vlite. so if you can use sysprep and then capture with petool cmd prompt then that 's it. easy and quick. As far as windows 7 impression with me is that it looks like a vista platform with extras that possibley will end up in vista sp3, unless microsoft is confident that they can sell windows 7 as an other than vista OS? I think they are just fishing for ideas and such until they have worked the kinks out and have a unique OS as removed from vista as possible. to call it "the new platform" In other words; windows 7 is to vista as windows milenium edition was to windows 98. I predict it will be released in 2010 as an upgrade DVD to Vista priced just right ! lmao.
