doubtful.
MS performs exhaustive regression testing on even the smallest fix before releasing it. MSKB articles with un-regression tested hotfixes are clearly marked.
a SP consists of well tested fixes.
basically you can find a large number of issues via google with any released OS version and any available SP for that version via a Google search, such as :
"windows 2000 service pack +BSOD"
or
"windows NT4 service pack +BSOD"
now, the relative amounts of hits for each might indicate that there are far fewer problems with NT4 then 2000, 2000 to XP, and XP to vista, but this is not the case.
NT was marketed solely to businesses. most Consumers weren't aware it existed and even if they were it was far more expensive then their "consumer" OS's, such as 95 and 98.
2000 was marketed mostly to businesses, but got far more consumer use because ME was so unpopular.
XP was the merging of the two into a single OS- divided into Home and professional editions, but from a common codebase.
For each new version, the number of savvy users dropped, with a large number of grandma's now trying to install SP2 in Vista, it's not surprising we might encounter issues.
