GetModuleHandleW and GetModuleHandleExW (pinning it) give back the handle LoadLibraryW returned for a path, a path to another folder finds nothing, and the bare name still finds it. Assisted-by: Claude Code:claude-opus-5-5 AI-Scope: the test client and its registration (cherry picked from commit 15b7e4ccc462826ffff57c1e19bb04d35fa57296)
