After Nvidia's suggestion i tried installing the graphics card into another machine with Windows 7 - which fixes the issue, so it looks like its my version of Windows. I ran the sfc utility which didn't find anything - so i don't think
NET framework from my system - because the control panel uses some variant of this, although this didn't help i do know the framework is inbuilt into Windows. I've had a brief look at the various Nvidia files but there's nothing unusual about the security privileges for any of the user accounts, tried changing them as well still with no luck. What is also strange is that it is only the 3d profile settings can't be changed the other options can, so this might be related to the security of the actualģd profile file although i can't identify/find this on my system. such as two different settings at the same time - and i don't think the changes are in effect. Reinstalled the graphics driver (the pnputil.exe shows removed), i have tried running in safe mode with video enabled, I have also tried running the exe as an admin - which fixes the problem however i must run each time as admin otherwise the settings revert I have tried creating and using a different admin profile altogether with no success. once i exit and restart nvidia control panel - the settings revert back. When i try to change nvidia control panel settings (3d settings) the settings do not save i.e. I know this software isn't Microsoft, but maybe you can help as it uses Window's security user rights I have already contacted nvidia technical support without any luck they suggest that this problem is related to either Windows, or is user profile related.
