This is an old problem. I don't know how to solve it.

This is caused by Windows Smart App Control, not a SourceGit-specific bug. Per Microsoft's official docs (Smart App Control - Windows apps | Microsoft Learn):

"Malware, Potentially Unwanted Apps (PUA), and unknown, unsigned code are blocked by default... In enforcement mode, apps cannot be run unless they are recognized by Microsoft's app intelligence services, or they are signed with a trusted certificate."

Since the SourceGit.exe release binaries aren't code-signed, Smart App Control (when in enforcement mode) blocks them outright — there's no "Run anyway" option like classic SmartScreen, and no per-app allowlist available to end users. The only documented remedies are:

1. The user disables Smart App Control (Settings → Windows Security → App & Browser Control) — note this can't easily be re-enabled without a clean Windows install.
2. The project code-signs release binaries with a certificate from a CA in Microsoft's Trusted Root Program.

Given this is an open-source project, I understand code signing has a cost, but it's worth documenting this as a known limitation in the README/release notes so Windows users aren't confused, since disabling Smart App Control isn't something most users want to do.
