On Windows, Claude Code changed how it reads the list of running processes through a Bun feature found only in internal builds of Bun. It uses that list only if it contains both Claude Code's own process and the process that started it. If reading the list fails, Claude Code writes a log line.\n\n**Why**\n\nThis does nothing unless the runtime provides that feature.\n\n- Area: Elsewhere\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
