Use of mod_auth_digest on Vista & beyond = show stopper at command line. This was on Win Vista, 2.3 @ r1040791 running at command line. Tested same on Win7. This does not affect Apache running as a service, even running as limited user, so I'm not sure quite to where to place this. It's per design but design doesn't always work.

When running as a service, the files are physically created.

Technically I guess this is minor and probably should just be documented. Either added to the mod_auth_digest doc or the Windows platform doc with a link to it from the mod_auth_digest doc.
Just wondering if an unnamed SHM (not file-backed) would be viable on win32?
