* WFP is Windows File Protection, in NT5 and Windows 2000 it maintains a cache
* of known good dlls and scans through and replaces corrupted DLLs with these
* known good versions. The only programs that should install into this dll
* cache are Windows Updates and IE (which is treated like a Windows Update)
*
* Implementing this allows installing ie in win2k mode to actaully install the
* system dlls that we expect and need
