When you user multiple programs at the same time, the Windows operating system will provide each program with an equal amount of the available system resources (processor and memory). But if you want to allocate a maximum amount of resources to one or more programs, then it is possible from the Task manager. Here is how it can be done.
Firstly open the programs that you want to define with a higher priority. Then press the “CTRL + ALT + DEL” keys on the keyboard and the Windows Task Manager will open.
From here click on the “Processes” tab and then look through the list for the processes that correspond to the application. Here we will chose the example of t he Mozilla Firefox browser with its associated process being “firefox.exe”. Right click on the process and chose “Set priority” from the menu that appears and you will have a choice between the following: “Low”, “Below normal”, “Normal”, “Above Normal”, “High” and “Real time”. Perform the same operation for each of your applications.

Example with the Firefox application and its associated process, firefox.exe
Important Note: While the “real time” option is offered, it is highly recommended that you don’t use this as it can lead to your system being unstable. If you want to give higher priority to an application, the wise choice is “Higher then normal” or “High”. Windows will then allocate more resources to this application, while still allowing the other to function.
