Jim, I've done great using XP as my virtual Machine for years!  It's time to grow up and do a new  Windows 10 virtual machine  or should I just upgrade the XP machine.   If I build a new machine should I use the size that I currently have for XP or does 10 take a lot more space? I share files but I do not mirror desk tops as I use Mac and Windows independently, however all of my designs, and other data saved to the Mac not to Windows.  Why am I doing this...Microsoft is giving me 30 more days to use XP because I can't find the Key Code even though  I can find the validation code, have the installation CD and have my original receipt!
