FWIW, Microsoft added a new "feature" to "Known DLLs" with Windows 2000. If a file is listed as a "Known DLL" nothing may replace it short of an operating system service pack. If you try replacing it, success will be reported but nothing will be changed. Microsoft will re-replace it with a cached copy that you cannot modify. IMO, this was done to prevent something like Windows 2000-lite, once and forever proving that IE is a necessary part of the OS. I also love having two copies of 2000+ files on my machine.
