Claude Code v2.1.2 8 Jan 2026

Windows Winget Installation Detection

What

Claude Code now detects when it was installed via Windows Package Manager (winget) for better installation source tracking.

Details

Detects winget installations by checking execution path patterns
Recognizes Microsoft\WinGet\Packages and Microsoft\WinGet\Links paths
Installation source now reports "winget" instead of "unknown" on Windows

Evidence

KF0() at line 370058 (winget detection, contains /Microsoft[/\\]WinGet[/\\]Packages/i)

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
