JSI Tip 8751. How can a script return the CPU Brand String on Windows XP and Windows Server 2003?

The CPU Brand String is contained in the FriendlyName Value Name under a registry key similar to:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumACPIGenuineIntel_-_x86_Family_15_Model__0Where _0 is the first CPU, _1 is the second CPU, etc..

Samples

On one of my laptops, FriendlyName at HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumACPIGenuineIntel_-_x86_Family_6_Model_9_0 contains Intel(R) Pentium(R) M processor 1700MHz.

On one of my desktops, FriendlyName contains Intel(R) Xeon(TM) CPU 2.66GHz at:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumACPIGenuineIntel_-_x86_Family_15_Model_2_0HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumACPIGenuineIntel_-_x86_Family_15_Model_2_1HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumACPIGenuineIntel_-_x86_Family_15_Model_2_2HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumACPIGenuineIntel_-_x86_Family_15_Model_2_3

I have scripted BrandString.bat to return all the FriendlyName data values.

The syntax for using BrandString.bat is:

BrandString VarName

Where VarName is a call directed environment variable that will be set as follows:

If CPU 0 cannot be found, VarName is set to NONE.
If CPU 0 is found, VarName is set to the number of CPUs and VarName0 is set to the CPU 0 FriendlyName.
If additional CPUs are found, VarName1, etc., is set to the appropriate FriendlyName.

BrandString.bat contains:
