This Poll was 9 July 2014. I wonder what percentage of players in LU has a XP system now. 36,7% to 43,4% (11 to 13/30 players) is pretty much in multiplayer with a very small community of players.
Not only are there way more than 30 unique players using LU, but as you said yourself, that is from 2014. It is now mid 2016, and numerous OS releases have come about since that time. Using that poll today is like saying the number of people using a cell phone in the 80's is still the same number of people using them today. It just doesn't make sense.
I'm sorry to say, but XP is old and outdated. It is unsafe. There is absolutely no reason to stay on it. Even MS ended support for running it in a VM because nearly every old program that exists which ran on it will run in the newer OS'es too. Sticking to XP is just asking to be hacked. It has been out for far too long now, and it is no longer receiving updates.
I, myself, have a copy of XP along with several other OS'es on a hard drive somewhere, but I wouldn't dare use it as my primary one anymore. That would just be pure stupidity. The cost of newer OS'es is so cheap at this point that not upgrading would be insanity.
