Rather than write a new checkproxy script, I simply added FreeGate to it.

 @echo off
 REM C:\data\sys\batch\checkproxy.bat 20250916 
 REM This is version 1.9 (w! checkproxy.bat_v1px.)
 REM Custom unified Windows proxy diagnostic tool
 REM v1.0 lists WinINET manual proxy, WinHTTP proxy, PAC/AutoDetect
 REM v1.1 replaces echo. with echo( to avoid command misinterpretation
 REM v1.2 adds PAC file existence check and SHA256 hash logging (114 lines)
 REM v1.3 (152 lines) adds debugging (section 9)
 REM v1.4 (161 lines) adds more debugging (section 10)
 REM v1.5 (182 lines) adds more debugging (section 11)
 REM v1.6 (204 lines) adds command reference (section 12)
 REM v1.7 (205 lines) Changed example.com to abc.com throughout
 REM v1.8 (217 lines) Added check for freegate proxy in addition to psiphon
 REM v1.9 (229 lines) Added output in final report to add freegate logging
 :: Normally the pac file is served by a web server.

 :: It assumes the PAC logic is known & trusted.
 :: It uses proxy.cmd to apply proxy settings directly, 
 :: bypassing the need for Windows to interpret the PAC file
 :: So even if http://127.0.0.1/proxy.pac isn┤ actually being served 
 :: by a web server, the system still behaves as if it is because the

 :: This is the where Windows typically looks for the PAC script URL.

 ::  [x]Don't use the proxy server for local (intranet) addresses
 :: 
 :: HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\AutoConfigURL
 :: AutoConfigURL = http://127.0.0.1/proxy.pac
 :: 
 :: C:\data\sys\batch\proxy.pac
 :: 
 :: Final Result
 :: WinINET: Enabled and pointing to Psiphon
 :: WinHTTP: Synced to match WinINET
 :: PAC: Registry keys set, logic assumed, Auto-Detect enabled
 :: The system is now fully aligned across all proxy layers.
