While cleaning up a client computer I found an issue with Internet Explorer where the proxy seeting could not be changed with out it automatically reverting back to its original setting. This persistant issue seemed related to a typical group policy setting but this was not possible because the system was running Windows 7 Home. Many others on the Internet had reported the issue with only one resolution, editing the registry.
The registry changes didn't seem to be long lasting until I found an article by Philip Turner that provided some additional registry keys that I was missing in my search.
NOTE: both of these keys had the proxy and loopback information embededed in their value data, which would not show up for a registry search for "127.0.0.1"
If you would prefer to use a registry file that has these changes already made, click the download and then go to where you saved the file and double cick to run it. We must notify everyone that modifying your registry could cause severe damage to the operation of your computer. Use these instructions or this file at your own risk.
In the case that I was working on, I also found that Symantec's Norton 360 Premium would cause these settings to become restored when the Firewall and Browser Protection settings were enabled. I am still investigating this issue. I don't typically recommend using this version of Norton Antivirus and recomend using just the basic version which doesn't cause this issue.

Thanks for this, it looked really promising but unfortunately after making all the changes it still doesn't work for me Nothing changed, any more tips???
Sorry to hear that this was not helpful in resolving your issue. Not knowing the details of your situation GReg, it is difficult to provide addition assistance. If you didn't notice the ending comment I made above to the post, some antivirus applications will try to proxy all web traffic so that it can be analyzed. It may be that your system has this function configured. My last suggestion to ensure that your system is certainly fixed is to complete a factory restore which will basically reinstall your operating system from scratch. I found that this was the only option on one or more systems since posting this. Good Luck!
Excellent post -- worked for me. BTW, there are a number of different ControlSet00x folders. Update all of them, as above
TC, under normal circumstances there should only be CurrentControlSet, ControlSet001, and ControlSet002. If you have additional ControlSet00x then making a change to them as well is advised.
This only worked for me if I did the last step (deleting the DefaultConnectionSettings string, etc.) again in the Wow6432Node area of the same name. Even after doing all of the above and missing this one section, the proxy was still in effect, and this was after a very thorough malware/virus cleanup. Thanks for the tips though so that I was able to figure it out. :-)
Worked for me too once I deleted the keys "DefaultConnectionSettings" and "SavedLegacySettings" from the Wow6432Node
search registry for DefaultConnectionSettings and SavedLegacySettings
Look for garbage key and export
Look for good key
Export good key and modify address to bad key location - Import - Reboot
