That sucks! So I can't get an ISO-file for my own Windows? I bought the damn computer so I should own the license!
The computer isa Sony Vaio and it's packed with bullshit programes and services that I never use. That's why I wanna make a clean install with RT7 Lite so I can decide what I want installed. But that's not possible then?
You sound very confused. What iso are you talking about? The sony bloatware can be uninstalled in Programs and features, the machine tweaked to your liking, after that just make an image using the inbuilt backup/restore feature or a 3rd party tool like the highly recommended macrium reflect. This image can be restored to the machine whenever required.
The recovery disks you have right now contain ALL the bloatware that came preinstalled, its not a clean iso. If you want to clean install, borrow a disk from a friend or get it from elsewhere, install the same edition you have right now, then activate with the sticker key.
