Internet Explorer proxy settings won't change - "some settings are managed by system adminsitrator"

Credit for this solution belongs here:

I came across a computer with a malware infection that had its Internet Explorer proxy settings configured, but I couldn't remove the proxy settings.  When I went to internet properties, it said "some settings are managed by system adminsitrator"

This computer was not part of a domain and had nothing set in local policies.  The fix was to change the value for ProxySettingsPerUser from 0 to 1 in the registry here:

HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\CurrentVersion\Internet Settings -> ProxySettingsPerUser

Live OneCare for computer optimization

I've always looked for easy wasy to optimize systems.  Usually, it just consisted of removing unnecessary items from msconfig.

But when researching the conficker worm, I came across Live OneCare's virus scanner which also does some registry optmization, which I will incorporate into my computer optimization routines.

The Live OneCare routine needs to be run out of IE and is located here:
