He said "2 gig," NOT "2 GB." Yes, 2 GB of memory s crippling for a in Win 10 Machine; 4 GB memory is considered a bare minimum for meaningful use of the computer. With VISTA, 2 GB memory MAY be adequate. The OP should be a bit more specific; what model computer, the computer's age, and how much of what type (PC100/133, DDR, DDR2, DDR3, or DDR4?) as well as its speed) of memory does it use. Adding memory may or may not be possible, but doesn't need to be particularly costly. The Progression for Microshaft software: (And YES, I HAVE run into [dinosaurs] running Win 10 with PC-133 memory!) MS-DOS (through DOS 6.22) > DOS/Win 3.1 > Windows for Workgroups (aka Win 3.11) > Win 95 > Win 98 > (we won't even mention Win ME here) > Win XP > VISTA > Win 7 > Win 8/8.1 > Win 10. Each version required increasing amounts of memory; the so-called minimum specified by MS was minimum for installation, not for meaning work. They also required increasing amounts of hard drive space. I would NOT "waste" the Win XP install on the current machine, as it is already old. A better alternative may be to simply sell it (if unopened/unused) on "ePay" (or similar) to recoup the loss. Neither XP NOR VISTA have ANY support from Microsoft; although Win 7 was s "officially" killed some time ago, MS will still provide security updates from time to time; Win 8.1 is still semi-supported. Any or all (MS) support for Win 7 AND Win 8.1 will finally end completely in 2023.
