Sick Too

I find that I get a lot of hits for my post discussing the "Logon process has failed to create the security options dialog" error message. This seems to be a continuing problem. I have posted a comment to the that post, but paste it as a new post as well as it may help:

The simplest and most reliable way to fix this problem is to uninstall "Service Pack 1". My computer is fine when that isn't installed, every so often it does a forced install, the problem returns, I uninstall and the problem goes.

Now the real problem, some programmes will only run if you have the Service Pack installed, something about resource allocation. So I can no longer uninstall. I have almost fixed it (meaning it is now an intermittent problem rather than constant problem). Turn of the side bar and Windows Defender. I believe that Windows Defender "argues" with other applications, such and anti-viral software.

There is a trick to turning off Windows Defender. It is a crafty little thing. First go in to "Programs", find Windows Defender, open it and turn it off. But, despite doing this, when you reboot your computer Windows Defender will still be running but in silent mode, ie it's running in "off" mode. To stop it running when you reboot you now need to go into msconfig (use the search bar). You will find "Windows Defencder" under the "Services" tab, AND IT IS STILL TICKED!!!!! Untick it. Ignore the warnings. And there you go.
