Found this, know if it's an improvement?
A warning, this may not be for the faint of heart or non-techies -- just ignore this if that includes you!
One of our many alert forum members Gophn realized that many notebooks being sold by mainstream manufacturers such as Toshiba, Sony and Gateway had not configured the notebooks correctly to take advantage of the two cores in the Core Duo processor. Processor performance is always a blend of the actual hardware engineering of the processor and proper software and operating system setup to utilize that hardware. Here's how to make sure your Core Duo or Core 2 Duo is taken full advantage of by Windows XP:
1. Go to Start Menu > Run. Type "Regedit" and press Enter.
2. The registry location: "HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession Manager" should have a key named "Throttle" there, if not make it by right clicking, point at "New > Key... name it Throttle.
3. Still in the registry, in the right panel inside the Throttle key should be a DWORD called "PerfEnablePackageIdle" with the value of 1. If not there, right click, point to New > DWORD and name it "PerfEnablePackageIdle". Type 1 in the Value data box (as hexadecimal) to enable the performance state policy behavior to increase performance.
4. Quit Registry.
5. Now you need to look at your boot.ini file to make sure that the command /usepmtimer is there. You can do this by Right Clicking on the "My Computer" icon, then go to Properties, click on the ADVANCE tab, then under Startup and Recovery click on "Settings", then click on EDIT. Make sure your boot.ini has the "/usepmtimer" in there (located in the very last line), if NOT then just copy and paste the below in there or type the /usepmtimer as the very last item of text so it reflects what you see below:
BOOT.INI example
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect /usepmtimer
NOTE: The BOOT.ini that I have given was meant for an example only. I would not recommend you to copy all of it and overwrite your own, unless if you are specifically using XP Pro SP2 on the first partition of the harddrive. Everyone else (XP Home, MCE2005, OEM pre-installed it onto different partition, etc.) should just add the /usepmtimer only.
6. Restart your computer.

I only see HKEY_LOCAL_MACHINE in the Registry Editor.
