Remove proxy settings via Group Policy

We have over 300 workstations that's being migrated over and the proxy settings needs to be removed. From what I gathered researching is that it can be disabled but the settings is still there and would not work. I want to do this via GPO and quickly remove these proxy settings.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

1.  Log on to a server in the Domain, and with administrative permissions, open up Start > Programs > Administrative Tools > Active Directory Users & Computers and expand your domain.
2.Right click the top-level domain or Organizational Unit where the policy should be applied, select Properties, then select the Group Policy tab.
3.Select the original GPO and click Edit.
4.From User configuration > Windows Settings > Internet Explorer Maintenance > Connection > Automatic Browser Configuration, clear Enable Automatic Configuration.
5.From Proxy Settings, clear Enable proxy settings.
6.  Click OK and close the GPO.

When the computers restart next time, it will clear the proxy settings.....

I'm running windows server 2008 R2 and under the GPO there's no "internet explorer maintenance" under Windows settings. I've researched this and it's seems that setting is not on updated GPO.
Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

In the 'User Config>Windows Settings>IE Maintenance>Connection settings.

Select 'Import the current connection settings from this machine' Choose LAN Settings and modify them if need be to what you need. I would leave all boxes unchecked. Apply the settings and run a GPupdate /force.

 Check the logs for any errors and test on a client PC.

 Be aware that if you later make changes under the 'Proxy settings' tab, it will override the settings in this area.

 Hope that helps.

There is no "IE maintenance" under my GP settings and will try to use the registry settings from sandeshdubey recommendation. My question is how do I push out the registry settings that's specified via GPO?
