Disable Remember Password MS Digital Certificate

Hi,

I want to disable the "Remeber Password" check box on the screen promptig for your password when you use a Microsoft digital certificate with High Security. I looked all over and so far im thinking there's no way... I tried this registry change HKEY_LOCAL_MACHINE\Software\Microsoft\Cryptography "ForceKeyProtection" DWORD value 2 but the check box is still there. Any help??

Thanks
