App Priority Keys for Windows

Set process priority from your Stream Deck. On Windows, these keys put the Task Manager priority setting on a key: high priority for a game, low for a heavy background app. A key can set the priority again each time the program starts, so your choice stays after the program restarts.

Features

Front App Priority: shows the app in the active window and its CPU priority (LOW to HIGH). Press to set yours, again to put it back

App Priority: the same for a program you choose, and it can set it again at each start

Restore Priorities: counts what was changed and puts it all back

English and Japanese

Safety

The priority from before is remembered

Keys show the priority read back from Windows

Realtime is left out, since it can freeze the PC

Protected: the Windows processes on its list (explorer, dwm and others), the desktop and taskbar, the Stream Deck app

Requirements and limits

Windows 10+, Stream Deck 6.9+. Tested on Windows 11

Higher priority alone does not make a program faster; no gain is guaranteed. High can make other programs stutter

App Priority changes every process with that file name. Setting it at each start works while its key is visible, and starts over when Stream Deck restarts

Programs run as administrator or protected by anti-cheat may refuse

Privacy

Reads program paths, start times and priorities; opens process handles. Nothing is logged or sent.

First release with three actions. Front App Priority and App Priority show the priority Windows reports for a program and set the one you chose on a press; a second press puts it back. App Priority can set it again each time the program starts. Restore Priorities puts back everything the plugin changed. Realtime can not be chosen. English and Japanese.
