I am using Windows 7 64-bit professional. I need to run a CPU intensive application and want to dedicate more than the default 25% of my CPU to it. How can I change the CPU usage allocation? Windows task manager options to chaneg priorities is virtually useless, and does not change the max. allocate CPU to a Windows app. which is 25%.

To my knowledge one cannot allocate CPU resources to particular processes, and there is no "default 25%"  All running tasks share time on the CPU, with preference to high priority tasks. Windows will give applications as much usage of the CPU as they want.  If you see in your task manager that the process in question is running at 25%, and your system idle is at or about 75%, then that means the application hasn't "asked" for more than 25%.

Yes, unfortunately you are right.

This is a misreading of Windows' confusing Task Manager. The software application I am using (R) is single-threaded, and so it cannot use more than one CPU. What the task manager shows is not the usage in CPUs but the usage as a percentage of the apparent total number of CPUs.

The correct answer is realted to single-threading, and how Windows reports CPU usage for multicore computers.
