It's hard to tell where that is pulled from, but its likely it hasn't been updated in quite some time. You can use WMI though to get that info, .name shows my processor properly.


 Code:
Break On
$strComputer = "."
$objWMIService = GetObject("winmgmts:\\" + $strComputer + "\root\cimv2")
$colItems = $objWMIService.ExecQuery("Select * from Win32_Processor",,48)
