I've just put it on a 2014 Toshiba laptop and basically it's a big download then over an hour installing and carrying over your system settings.
So far everything seems to work pretty much as before but I suddenly realised the sound is not working in fact it does not detect any audio components (but there are some!)
Installing latest driver for that just now but will have to leave trying it for later - ah... it says timed out on install... so yes there may still be problems but no doubt this will be resolved sooner or later.
