WinKillSwitch v0.3.9: CPU and memory limits
Limits
Keep a heavy program from taking over your PC, without closing it.
- Open a process's Details and choose Set limits.
- Processor: 50%, 25% or 10% of your processor for the whole program, all its processes together. It runs slower, never breaks.
- Memory: 4 GB, 2 GB, 1 GB or 512 MB of RAM per process. Windows moves the rest to disk instead of refusing memory, so the program keeps running.
- Limits are remembered by program name and come back every time it starts. Settings > Limits lists them; remove one and the program is free immediately.
- Windows' own processes cannot be limited.
Tested on a real machine: a busy process went from 8.3% to 2.4% of the processor under a 2% cap, and a process holding 481 MB dropped to 127 MB under a 128 MB ceiling while it kept running.
