I'm having difficulty installing a wireless usb keyboard and mouse with windows xp pro SP3. Also can't install a usb keyboard or a usb mouse. So I wanted to see if my driver.cab file contains the same d4rivers as sp3. So I downloaded WindowsXP-KB936929-SP3-x86-ENU.exe to extract the files and determine if the cab files are the same. However when I open a cmd shell and type WindowsXP-KB936929-SP3-x86-ENU.exe -x:c:\sp3 from teh c:\sp3 folder I get the error message C:\sp3\WindowsXP-KB936929-SP3--x86-ENU.exe is not a valid Win32 application.
Basically I'm hosed as my OS is obviously has an issue trying to install a usb device and that's all they sell anymore. Makes me want to go right out there and buy another new system NOT. Help would be appreciated. I expect many users will have issues as their ps2 keyboards fail.
