CHANGE APPLICATION PRIORITY

If you don't have a dual or multi-core CPU, you can still speed up applications and overall computer performance by changing priority settings for programs of your choice. Basically, assigning high priority to an application will speed up the application itself, but might affect overall system performance. Similarly, assigning low priority to a resource-hungry application will speed up overall computer performance, but will slow down the application itself.

You can change application priority in the Task Manager:

1.   Open the Task Manager by pressing Ctrl+Shift+Esc.
2. Now go to the Applications tab, right-click the application you want to assign to a different processor and select Go to process.
3. Right-click on the highlighted process, navigate to Set Priority and select the desired priority from the list.
4. Close the Task Manager.
