Process & Port Analyzer

Changelog

Full release history and version notes for Process & Port Analyzer – Network & Process Monitor.

Version 1.1

Latest June 2026

New

  • Refreshed look — crisp vector icons across the toolbar, tab bar, sidebar buttons, and summary cards that stay sharp at any size and recolour automatically with the dark/light theme
  • Shorter, clearer tab names with matching icons: Processes, Listening, Connections, Failed Logins, Sniffer, Firewall

Improved

  • Firewall rules now accept a single port (80), a list (80,443), or a range (8000-8100) for local and remote ports
  • Addresses are validated when building firewall rules — single IPs, subnets (192.168.1.0/24), ranges (192.168.1.1-192.168.1.50), and keywords such as LocalSubnet or DNS are accepted; duplicates are skipped and invalid entries are rejected with a clear message
  • Memory usage is shown more precisely — small processes now display one decimal (e.g. 0.5) and the Memory column sorts by actual size
  • Faster Failed Logins — loading stops once it passes your chosen time window instead of scanning the entire security log
  • Faster connection and listening lists thanks to smarter lookup of process names and paths

Fixed

  • The "Listen" connection-state filter now works (it previously showed no rows)
  • The module list now shows every module — processes with very many loaded modules are no longer cut off
  • The packet sniffer no longer slows down or freezes during long captures; the on-screen log is kept to a manageable size and the capture file is written more efficiently
  • More stable overall — unexpected errors now show a message instead of closing the app, and closing the window during a capture no longer causes a crash

Version 1.0

January 2026

Initial Release

  • Running process viewer — PID, process name, full executable path, and loaded module list
  • Active TCP/UDP connections — PID, protocol, local/remote IP and port, state, process name
  • Listening ports viewer — all TCP/UDP ports in listening state with owning process details
  • Raw packet sniffer using native Winsock APIs — decodes TCP, UDP, ICMP, and IGMP packets
  • Packet filtering by source/destination IP and port
  • Packet hex dump — timestamped entries with full hex and ASCII side-by-side output to dump.log
  • Windows Firewall rule manager — view, create, enable, and disable rules from within the app
  • Block connection from context menu — pre-fills the firewall rule creator with connection details
  • Sortable columns across all list views with correct numeric sorting for ports and PIDs
  • No external dependencies — uses only native Windows APIs (iphlpapi, psapi, Winsock2, Firewall COM)
  • Supports Windows 7, 8, 10, and 11 (32-bit and 64-bit). Administrator privileges required.
