Claude Desktop's Windows always-on-top bug: root cause known since August, PowerShell fix inside

Claude Desktop on Windows stays on top of every app after silent background updates: restoring z-order makes it inherit WSEXTOPMOST from whatever window sat above it (taskbar, IME helper, tooltip). Users diagnosed this in August; closing the window doesn't help since it just hands off to the running instance—you must quit from the tray, and it recurs on the next update. The post includes a PowerShell SetWindowPos one-liner for an instant unstick, plus GitHub issues (one with 300+ reactions labeled invalid), asking Anthropic to fix the restore and add a 'Keep window on top' toggle.
