I found one tool "Windows Download Integrator" at MDL but its outdated... Can anyone suggest same type of tool to integrate driers & updates to wim?? Or script???
NOTE: This Tool integrates updates only. Here is a thread regarding that topic (can´t find atm). It´s a bit picky to integrate that stuff into the WIM. For instance .NET should be integrated first. Most updates can be integrated in a batch; BUT some some need to be processed alone. As i had problems to get this working properly (some updates didn´t get integrated) i went the Audit Mode route.
OK... nice advice but don't you think Audit Mode is much lengthier process & on windows 8 guessing which update will refuse to install is a pain....
audit/sysprep/capture is probably the best way to update a Windows version for personal use. It might not be compatible with certain future tinkering tools. I've had complaints from people that liked to remove certain features with rt7lite that a sysprepped image was causing problems where an image that simply had updated kbfiles in the form of .msu add-package worked fine. If you're not concerned about future tinkering, sysprep/capture is the way to go. It does take quite a long time to capture the image, IMO the only real drawback.
Capturing here takes less than half an hour (about 25 mins) . Doing in VM is very comfort for such things.
