Hi Tuomas,
While true, this obvious a big financial burden for many people. The best alternative is to make your laptop dual-boot. This is effectively the same as having two laptops as both installs are totally independent of each other. It’s also legal, you are allowed to use your current windows license for the new install too. Or you can use an old windows 7 version for your DJ box (hint, hint).
It’s not all that difficult to setup, but you might want to find a computer-savvy friend that can help you with creating the clean second boot install. After that it’s just like setting up windows on any computer and you can do that yourself. Get a clean windows version and strip it further down (i.e. uninstall everything you don’t need/want or at least switch it off). Turn off windows services (Google the subject there is plenty of info). No bluetooth or even internet and virusscanners (you can do it while installing the laptop but switch it all off as soon as your done).
Well, plenty has been written on that subject here, so use the search box if you want more info.
