Some times we increase or decrease the priorities of process when required. Increasing the priority of a process will make it faster and vice-versa. 
Usually when you have assigned a particulate priority for a process in windows, it retains the priority you set only for the current windows session.When you restart or shutdown windows and when you again check the programs priority, it comes back to normal. You you need to start setting the priorities all again.
This process can be automated if you have the Prio – Process Priority Saver Application.
Using the Process Priority Saver is very easy.
Now the priority for those applications or process will be automatically set and saved so that you need not again right click them again for setting the same priority again.
Apart from setting priorities of processes, the program enhances the windows task manager by adding two new tabs to it namely, TCP/IP and Services. The TCP/IP tab gives you all the details about the network connections.
Hovering over a service in the services tab will give you detailed information about the service so that you can easily decide whether the service is needed now or not. You will have options to stop or start the services on right clicking them.
Prio is a very useful application if you are a serious daily windows user and its free for use.
