Do you think that any particular application is running too slow in your Windows 7? Sometimes the application we are using run quite slowly while other less important apps run perfectly fine, this is because Windows assigns equal priority to every program. You can increase the priority of any application by increasing the priority of it’s process, in this way Windows will give more resources to a program who’s priority is high. It is very easy to increase/decrease the priorities of any particular process in Windows 7.
