@theoutrider Yikes. Say "Windows XP is not supported — not even from Microsoft; they stopped supporting XP on April 8, 2014. Windows XP has several serious unpatched security exploits and viruses." and send them this URL? https://www.microsoft.com/en-us/WindowsForBusiness/end-of-xp-support
@theoutrider Only exception is if they're using special types of XP embedded — "Windows Embedded Standard 2009 and Windows Embedded POSReady 2009 continue to receive Extended support through January and April 2019, respectively"
