Windows

System-wide HTTP/HTTPS proxy — all apps that honor Windows proxy settings (Edge, Chrome by default, .NET apps, most CLI tools) will route through helodata.

Settings UI (Windows 10/11)

1. Settings → Network & Internet → Proxy → Manual proxy setup.
2. Toggle Use a proxy server on.
3. Address: gate.helodata.io (or your ISP IP). Port: 7777.
4. Click Save.
5. The next outbound request prompts for credentials:

   • Username: full proxy username (e.g. helo_s1a2b3c4d5e-type-res-region-us)
   • Password: sub-user password

The Settings UI does not persist proxy credentials — they're stored per app. For unattended use, prefer PowerShell or netsh.

PowerShell (programmatic)

$proxy = "http://gate.helodata.io:7777"
Set-ItemProperty -Path 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings' `
                 -Name ProxyServer -Value $proxy
Set-ItemProperty -Path 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings' `
                 -Name ProxyEnable -Value 1

To remove:

Set-ItemProperty -Path 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings' `
                 -Name ProxyEnable -Value 0

CLI tools

curl on Windows reads HTTP_PROXY / HTTPS_PROXY:

set HTTP_PROXY=http://helo_s1a2b3c4d5e-type-res-region-us:[e-mail]:7777
set HTTPS_PROXY=%HTTP_PROXY%
curl https://ipv4.icanhazip.com

For permanent envvars use System Properties → Environment Variables.

WinHTTP (system services, .NET)

For Windows services and .NET HttpClient (which uses WinHTTP, not the user proxy), set the system-level proxy:

netsh winhttp set proxy "gate.helodata.io:7777"
netsh winhttp show proxy

To revert:

netsh winhttp reset proxy

WinHTTP cannot embed credentials in the proxy URL — the calling app must supply them via IWebProxy.Credentials.

Verify

curl https://ipv4.icanhazip.com

Or browse to that URL in Edge.

Common pitfalls

• Two proxy systems (WinINet for user apps vs WinHTTP for services) — you may need both.
• VPN clients often install themselves as a higher-priority proxy hook. Disconnect VPN to test.
• .local and corporate suffixes bypass automatically — useful but watch the bypass list.
