(stole the following post from cup, thanks cup
Here in the Free Clinic, we deal with many different iterations of Windows operating systems.
Each has its own nuances - what works on one might not work on another, things are in different places, some features may or may not be present in your version.
Post your OS family, version, bit-level (32- or 64-bit), and service-pack level.
Bad examples (and, what's missing):
"I have XP" ((is it Home, Pro, Media Center (2002, 2004, 2005?) RTM (no SP?) SP1, 2, or 3?)
"it's Vista" (Home Basic, Home Premium, Business, Ultimate? 32- or 64-bit? RTM (no SP?) SP1? soon, we get SP2.)
"Windows 2000" (there are four service packs to deal with.)
"Server" (if you're posting a Server question, you know how many variants there are.)
"XP Home, service pack 3"
"Vista Home Premium (32-bit), SP1"
and so on.
The same goes for any software (be it Microsoft's, or a third party's) - the more version-specific you are in your post, the better.
Complete information helps to better help you.
Thank you for your co-operation,
