Unable to update or start Steam on Windows 7?

I am having problem to start my Steam program due to updating of the platform. It is not able to get pass 0%. Everthing works again after I change to this setting! Of couse, I have deleted clientregistry.blob too.

After changing the setting, delete the original steam shortcut on desktop and try running the steam.exe program directly from its folder.
