fellow wincerters, just registered, this is my first question I used `rt7lite` to strip down my `Win7AIOSP1.iso` since `wtk` provides rather few options and `winreducer` fails to save my presets (error: sth about "missing entry point"). As a result i got a slim `Win7HomeBasic.iso` as suggested for x64. I did not rebuild the other distros with `rt7lite` which is `why` i assume wtk doesn't show any other when mounting the image. following steps 6-7 i copied the `\sources\install.wim` three times (one each for `HomePremium`, `Professional` and `Ultimate`). now: 1. how exactly do you "upgrade"
