If you have a dual-core processor, you may discover that certain older applications that ran fine on systems with a single core CPU have problems running with two cores.
For example, your application may suddenly begin maxing out the CPU usage at 100 percent, appearing to lock up.
Windows XP Professional’s Processor Affinity setting allows you to work around such problems by configuring older applications to use only one of the cores. Here’s how to set it up:
1. Press Ctrl + Alt + Delete
2. Select Task Manager.
3. Select the Processes tab.
4. Right-click the process associated with the application.
5. Select the Set Affinity command. (If you don’t have a dual-core system, you won’t see the Set Affinity command.)
6. From the Processor Affinity dialog box, clear one of the CPU check boxes.
Note: This tip applies only to Windows XP Professional.
