Hi Abi8220,
/numproc=number switch sets the number of processors that Windows will run at startup.
With this switch, you can force a multiprocessor system to use only the quantity of processors (number) that you specify.
This switch can help you troubleshoot performance problems and defective CPUs.
Note:
These switches apply to Microsoft Windows XP, unless otherwise specified. It is suggested to backup the Boot.ini file before editing.
To add the /Numproc switch, you may refer the below steps:
Click Start, click Run, type msconfig, and then click OK.
Click the BOOT.INI tab.
Click Advanced Options.
Click to select the /NUMPROC= check box, and then click 1 in the /NUMPROC= box.
Click OK two times, and then restart the computer.
