Sorry if the question has already been. As a win toolkit to integrate service pack 1?

SP1 integration is horribly messy and really not suggested.

However links to download Windows 7 w/sp1 iso's (legally provided) are in the downloads tab of the toolkit.

no no no ..... do not want to once again thrust package ruchsskogo language. SP1 in Russian have not seen yet

Sorry then youre only choice is to use rt7lite. Its not very clean and gracefull though.

You can also do it "manually". It ends up nice and clean, but it is definitely NOT graceful and is NOT for the faint of heart. It involves installing Win 7 RTM in a VM, switching to Audit mode, installing SP1, generalize, convert to a VHD, mount the VHD and clean up a bit, convert the VHD to an install.wim with imageX, replace the install.wim in Win 7 RTM with the new one you created, etc, etc. This method is referred to here - http://www.msfn.org/board/topic/133491-windows-7-keep-list/page__view__findpost__p__995141

Cheers and Regards

TECHNICALLY Thats "Reverse Integration" NOT "Slipstreaming", which is what the OP was asking for. :aggressive: :owned: :giveheart:

So you want a russian version?

OK, download an SP1 image like Kels said above and then integrate the language pack.
