That's a reported Claude Desktop bug, not something you turned on. There's no setting inside Claude to fix it, but there is a free workaround, and it's below. This page also explains what Anthropic's own bug tracker actually says, since the linked issue may look resolved when it isn't.
Windows itself has no built-in shortcut for this, but Microsoft's own PowerToys utility adds one. It toggles the same always-on-top flag that's stuck on Claude's window.
Install Microsoft PowerToys from the Microsoft Store or GitHubFree, made by Microsoft, safe to install
Open PowerToys Settings and turn on the Always on Top moduleIt's off by default
Click the Claude window so it's focused
Press Win + Ctrl + TA coloured border briefly outlines the window when the toggle fires
If nothing seems to change: press the shortcut a second time. Because Claude's window is already sitting in the topmost band, the first press can register as "pin" rather than "unpin." Watch for the border flash to tell which state you're in.
If it comes back later: some users report Claude re-asserts the behavior after a restart or an update. The shortcut is a toggle, not a permanent setting, so you may need to repeat it.
Windows lets any application mark its own window as "topmost," a single flag that keeps it drawn above every ordinary window regardless of which one you're actually using. Normally an app sets that flag briefly and clears it — Task Manager's own always-on-top option, for instance, is user-controlled. The reports describe Claude's window getting stuck in that state with no in-app control to release it, so it stays above whatever you switch to, including new windows and popups from other programs.
Worth reading before you conclude it's fixed or being worked on — the status is easy to misread.
Filed August 2026, describing Claude Desktop on Windows 11 staying on top of newly opened windows. Closed the next day as a duplicate of an earlier macOS report, labelled invalid. Comments continued past that closure — "still persists," "very frustrating," "how is this still not fixed?" — as recently as mid-September 2026.
Filed June 2026 on macOS, same symptom. Closed as not planned, also labelled invalid. One commenter reported it stopped after changing an unrelated setting; that has not been confirmed as a general fix, and most comments simply say the problem is still happening.
Both issues sit in the claude-code repository, which tracks Anthropic's command-line tool rather than the Claude Desktop app itself — plausibly why they were closed rather than routed to whoever owns the desktop client. Closed and labelled invalid does not mean resolved; it means the tracker isn't following up. If you want it fixed, commenting on the open threads or reaching Anthropic support directly does more than either issue currently is.
Since you're here for a Claude Desktop bug rather than shopping for a utility, it's worth being direct: Always On Dock does not fix this. It never changes another program's window styles, including the topmost flag causing the behavior above — that's a deliberate limit in how it's built, not an oversight.
What it does is unrelated but occasionally useful alongside this: it's a small Windows utility that reserves a strip of your desktop — through the same mechanism the taskbar uses — for one to three windows of your choosing, so a maximized browser or editor can't cover them. People use it to keep a chat app, notes, Outlook, Excel, or a video permanently visible beside their main work, without anything floating over what they're doing.
If you dock the Claude window into that strip, it's confined to a narrow slice of one edge of the screen — so even though the topmost flag itself is untouched, there's far less of the screen left for it to sit above, and Windows won't let a maximized window expand into that strip regardless. That reduces how often you notice the bug day to day. It doesn't resolve it.
It's a reported bug, not a setting you turned on. Multiple users on Windows and macOS describe Claude's window remaining above every other application, with no toggle inside Claude to turn it off. It's tracked in Anthropic's GitHub issues but hasn't shipped a fix as of this writing.
Install Microsoft PowerToys, enable its Always on Top module, focus the Claude window, and press Win+Ctrl+T. If nothing visibly changes, press it again — the first press can pin a window Windows already treats as topmost.
It's reported as unwanted behavior with no way to disable it in Claude's own settings. It's been filed at least twice, closed as a duplicate and as not planned, with users still commenting into September 2026.
No. Always On Dock never changes another program's window styles, including the topmost flag, so it doesn't remove the behavior. Docking the window does confine it to a narrow strip, which reduces how often it covers something — that's a reduction, not a fix.
Yes — an earlier report describes the identical symptom there. One commenter said it stopped after an unrelated settings change, which hasn't been confirmed as a general fix.
