ดาวน์โหลด SysManager 1.51.7

[1.51.7] - 2026-06-29
Fixed
- Unknown command-line flags now report a usage error instead of silently opening the app. Running SysManager.exe --bogus (or any unrecognized --flag) used to fall through to launching the GUI and exit 0, contradicting the documented contract (--help states unknown options exit 2). Unrecognized flags are now treated as a headless usage error: they print "Unknown option" with the help text and exit 2, while the internal startup sentinels (the elevation relaunch and the in-process update applier) are explicitly excluded so they still route to their own startup paths. Bare non-flag arguments are still ignored.
