[Bug]: BrowserPicker is bypassed for HTTP/HTTPS links on Windows 11 Build 26200

[wuweixiao96-max]

Summary

BrowserPicker 3.2.3 installs correctly and is registered as the default handler for HTTP and HTTPS.

However Windows never launches BrowserPicker when opening links from:

• Excel
• Zalo
• Win+R -> start https://google.com

Instead Microsoft Edge opens immediately.

BrowserPicker does not receive the URL and no application log entries are generated.

This worked correctly the previous day with BrowserPicker 3.1.3, then suddenly stopped.

Reproduction

1. Install BrowserPicker 3.2.3
2. Set BrowserPicker as default for HTTP and HTTPS
3. Verify BrowserPicker.exe launches manually
4. Open any https:// URL from Excel or run:

start https://google.com

Expected:
BrowserPicker window appears.

Actual:
Microsoft Edge opens directly.
BrowserPicker is never started.

Additional information

Windows Build:
26200.8875

Verified:

• BrowserPicker.exe launches normally.
• Registry points to BrowserPicker.exe.
• .NET 10 runtime installed.
• BrowserPicker receives no URL.
• Application log shows no activity when opening links.

Environment

• BrowserPicker version: 3.2.3--beta1+e3a144228fae022e31f6e9ce624fa41c8f54d80d
• OS: Microsoft Windows NT 10.0.26200.0

I suspect you may have to go into the settings app and manually confirm default browser to be BrowserPicker
