This is a w7 x64 EOL captured wim i am currently working on, IE11 and Net 4.8 installed. There is an issue on winsxs cleanout that i am working with nuhi on, its 300MB bigger than it should be so take away 300 from the FIS and the os will be 5193.3MB.
All i have done is to remove 3rd party published drivers(not ms published drivers), keyboards and languages, Recovery, .Net caches, cache and temp files, winsxs backup and winsxs. I havnt actually touched the meat and bones of the os, ive gone around the outside and trimmed the fat off from there. I would call this Stage1 or Safe Lite.
This is the captured wim as is, only cleanup before sysprep was Disc Cleanup with all options ticked and imagex default exclusions.
