XP and 2003 have been end-of-life for years. They both were released 14+ years ago. So you can just change what I said to:

"because a lot of them have ineffective IT departments/mangement and never applied the MS17-010 patch or are running ancient operating systems."

edit: And in fact, Microsoft did release a special XP hotfix for this vulnerability yesterday: https://blogs.technet.microsoft.com/msrc/2017/05/12/customer...
