Dad finally got tired of Windows issues about a year ago and had me set his laptop up to dual boot Windows and Linux.
He never uses the Windows side any more. And he never calls me with problems.
Mom still does. She’s still using Windows.
The other reason is because some of the external drives I access are in the NTFS format, and sometimes if a problem develops I have to boot up XP and check the disk twice before I can use it again. Linux even says on the screen I have to do it. Why? Because even after about fifteen years since introducing the standard, MS has STILL not published the specifications for it and apparently never plans to. So, the Linux coders have managed to figure out most of it but get no help whatsoever from the MS pukes.
