If your using Windows ME YOU SHOULD upgrade to Windows XP, if your on 98SE you should wait till the new release of Windows... which right now is code-named: "Longhorn" (and no that aian't a joke).
They recently "accidently" leaked some info on "Longhorn" Alpha yesterday:
An internal alpha build of Microsoft's next version of Windows, code-named Longhorn, made its way onto the Internet early Tuesday.
The leaked build, which is numbered 3683, appears to be from late September and sports quite a few new feature concepts?although many are not yet functional.
News of a leaked Longhorn build cropped up late last month when screenshots posted to Windows enthusiast sites purported to showcase the next-generation operating system. But the select few with access to the code initially opted to keep it under wraps rather than risk incurring the wrath of Redmond.
