Why is your computer running at 100% capacity when you're not using it?
Use throttle to cool your computer, prolong the life of your CPU, and save a little electricity too.
Throttle is a perfect background utility for machines running 24 hours a day.
Have a program that runs too fast? (perhaps an old game?)
Use winThrottle to slow your machine down so it will run at the proper rate.

What winThrottle does:
Throttle uses a feature in your system's hardware to modify the clock speed going to your CPU, rather than using software "delay loops" or HLT instructions to slow your machine down. This method provides very smooth slowdowns without any incompatibilities with software.

winThrottle Features:
- "on the fly" adjustability for the amount of slowdown.
- CPU load based auto-throttling. Slows down your CPU when not in use, speeds up as demand increases.
- simple to use interface.
- hides in the system tray when minimized.
- small memory and CPU usage footprint, machine can also be throttled with NO memory or CPU usage.
- command line support for complete background usage.
- completely compatible with other system slowdown utilities.
- free and open source.
