Sliprail Process Killer gives you the same keyboard workflow on Windows and macOS. Open the launcher, search by window title, app name, or process name, then end a frozen target without having to remember different system steps on each platform.
Use it when an app will not close normally or a background process needs to stop. Ending a process can discard unsaved work, so it should not replace the app's normal Quit or Close command.
Process Killer works well in situations like these.
Try the app's normal Quit or Close action first. If the app still responds, save, export, or recover what you can before ending its process.
Win + Space on Windows and Option + Space on macOSProcessKiller, select Process Killer, and press Space to open its target listWindow results use the window title and can also match the owning app name. Process results use the process name and may also show its command or parent process details, which helps distinguish similarly named entries.
If you press Enter on ProcessKiller without first pressing Space, Sliprail opens Task Manager on Windows or Activity Monitor on macOS.
Task Manager and macOS Force Quit are still useful when you prefer the tools built into the operating system. Force Quit focuses on visible apps, while Activity Monitor shows processes in more detail. Sliprail is not a replacement for those diagnostic views. Its advantage is a quick, searchable keyboard workflow that stays the same on both supported desktop platforms.
Ending a process can bypass the app's normal shutdown and recovery flow. Unsaved documents, in-progress uploads, file writes, renders, or terminal jobs may be lost or interrupted. There is no undo after the target has ended.
A selected window belongs to a process. If several windows share that process, choosing one of those window results may close all of them, not just the window whose title you searched.
If Sliprail is running with standard permissions on Windows, it may not be able to end an administrator-level process. Run Sliprail as Administrator only when needed, and read the Windows administrator permission guide before setting Sliprail to always run as Administrator.
On macOS, protected processes, root-owned processes, and processes belonging to another user may not appear in the list, and macOS may refuse to end them. Process Killer does not bypass macOS security protections.
Sliprail hides known critical system processes and its own process from the target list. This reduces obvious mistakes, but it cannot determine whether every remaining process is safe to stop. If you do not recognize a target, leave it running and inspect it with the operating system's tools first.
Process Killer is available in the Sliprail desktop app for Windows and macOS. It is not available in Sliprail Web, does not diagnose why an app froze, and does not recover work after termination. When ordinary Quit has failed, the same final steps work on either platform.
