There's a process called "slip-streaming" https://www.google.com/#q=slipstream+windows+7 where a standard stock ISO image is combined with a set up selected updates (Windows updates) and drivers, so that the installation includes those items automatically.
I've thought about doing that numerous times in the past, but these days it's less necessary with Win7 in a VM since for a new VM, I just clone the VM that already has everything in it. :-)
yeah vms are cool- love beign able to save them/back them up quickly- but unfortunately in my case, i need windows to be it’s own os/host etc because the work i do needs it’s own graphics card - photoshop only runs ‘o.k’ in vm- and windows games- nope- no way- if i could run vm with full graphics power- I woudl do away with dual boot altogether- as vm is way more convenient-
I’ll check out that slip streaming process-
