Log:
[SMSS]
- Use CRT string functions to loop through multi-strings.
- Do not fail the full KnownDll setup if one dll fails to load. Instead, just properly
skip the file (and related to that, fix a bug when skipping excluded known dll files).
- Page files should be created only when we are not in WinPE mode (aka. MiniNTBoot =
FALSE).
- Formatting fix in smloop.c, no code change.
