Thank God they stopped supporting Windows 98 last month.
Now they have more manpower to fix the holes in Windows 2000 and XP.
While XP needs all the help it can get, I doubt support of Win98/ME was taking much manpower.
Anyone can visit Windows 98 Downloads, and count the number of "critical" updates. I think I counted 22, dating back to 1999.
At least one, the "Windows IDE Hard Drive Cache Package", while perhaps being "critical", doesn't actually have anything to do with security.
