We're running windows ME. Now, don't laugh, don't cringe, the PC is 6 years old and that was the latest and greatest*cough* version out at the time.
You must live in some parallel universe where Windows 98 doesn't exist, then??Seriously though, your parents sound like a couple of Luddites. You're not doing bad to get six years out of a PC.
You should probably 'upgrade' to Windows98SE. You'll probably find it cheap on eBay or something.
