Predefined Windows Security Template Details
Table 1 describes predefined template files, from %systemroot%securitytemplates. Empty cells mean a file is missing in the corresponding OS; when file sizes change, it's safe to assume contents also change -- usually, to accommodate new security features, version names, and so forth. For more information on .inf files, visit www.microsoft.com/technet/ and search on the filename.

In my next tip, I'll cover default security templates that live in %systemroot%inf, and how they can sometimes save your bacon!
