Well, Windows 98
is very old now, but many people still use because of it's stability. To be honest, I prefer Windows 98 to Windows XP, but I use XP because some important software I use can't run on 98. If it did, I would gladly change back.
I know it's a pain when a lot of things you want to run require a different version of your operating system, but that's life. Unfortunately there's rarely anything that can be done.
