Lag Spike with Windows 7 Fix?

Uh, yeah..

Recently (Within the last two patchs) I have been spiking out of control. Up to 2k ping in extreme cases.

I have tried several solutions to this, but can`t seem to find one that works.. Including this.

* Open regedit
* Go to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile
* There will be an entry for network performance throttling, default value is 10; set it to FFFFFFFF hex (willl look like 0xFFFFFFFF to the right of the entry)
* Reboot

With this, I got up to,
* Open regedit
* Go to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\

When there was no Multimedia?! At least, none I could see.

Help please?

- Thanks in Advance!
