Ian Graham Martinez	19d29f1ea6	Screen redirected registry traffic in a Windows service Each registry host gets its own loopback address, where a LocalSystem service serves mitm_service, connecting upstream through a resolver that ignores the hosts file. It trusts its CA machine-wide and serves the empty CRL that schannel needs. The service writes the hosts-file block once it listens. Pausing it removes the block and continuing rewrites it; a stop, crash or shutdown leaves it, so a restart fails closed and picks up a changed host list.	2026-10-22 11:48:15 -04:00
