> In fairness to Windows (and I never thought I would say that), .DLL files are now versioned via WinSxS

Apparently, that's not working as well as MS hoped, either from a technical or adopting perspective: From the same wikipedia article:

- However, runtime libraries in Visual C++ 2010 no longer use this technology; instead, they include the version number of a DLL in its file name, which means that different versions of one DLL will technically be completely different DLLs now.

- a bug in sxs.dll causes heap corruption, leading to application crashes. This issue is not fixed by any XP service packs. Users must manually install a QFE (Quick Fix Engineering).

It should be noted that including the version of the library in the filename has been a simple solution that's been used in Unix since the early '90s, when shared libraries become fashionable. (Oh, Ultrix - how I hated not having shared libraries when I had to use you... Luckily, you're dead now)
