What would be the best way to minimize the CPU usage in order to give certain programs full CPU strength? We generally save the changes and close multiple applications to allocate maximum CPU usage time to most important applications or processes. Lazar Freezer offers a better solution here. It is a small open source tool with the ability to lessen application’s CPU usage, so that you can smoothly operate other applications waiting in queue to get maximum CPU time. As its name hints, it actually does nothing except freezing down all the user specified running applications by taking down their CPU usage to minimum and in some cases, down to less than 1% CPU usage. This significantly increases the overall processing time for other important applications.
Lazar Freezer can come handy in many situations. You can for instance freeze media player, word processor, audio workstation, etc., for a few minutes to allow, lets say, media encoder to perform conversion operations smoothly. When conversion process is finished, you can restore frozen applications back to their original state.
It sits in system tray, letting you bring up main window any time to freeze and defreeze applications. It also supports hotkey combinations to quickly lock and unfreeze locked applications. All that is required is to use Ctrl+Win+S to lock the active application. Once application is locked, it will appear on main interface.
Alternatively, you can keep applications hidden until they are unlocked and choose to freeze their child processes as well to enforce minimum CPU usage. When you want to unlock frozen applications, either use the hotkey combination – Ctrl+Win+L or select the application and click Defrost from main interface. It must be noted that applications depending upon core system processes shouldn’t be locked, as doing so may damage your system. Be very careful!
