Question

I've been trying for the last two weeks to fix the use a proxy server setting It keeps randomly turning on and filling in with "http=localhost:8451;https=localhost8451"and every time it does this I cannot access anything through my network it's not even giving it a port number but it keeps turning back on and feeling this out each and every time no matter how many times I empty this box and turn it off I've already scanned for viruses with Norton it can't find anything virus related so I'm thinking it has something to do with something I managed to somehow break internally with my computers system I've already ran a command prompt line to try to fix it and I don't remember what the line was if you're wondering I remember what it did It did a scan in prompted me to restart my computer It didn't fix it either and I'm looking for any other ideas of how to fix this because I can't find anything on it and if you're wondering I am running Windows 10 OS build 19045.3324 any information you may need I can provide

Hello AlexanderWaters,

Welcome to Microsoft Community.

I read the thread you posted here in its entirety. Looks like the "Proxy Settings" in Windows 10 keep turning on automatically, right?

In general, there are two possibilities that cause the proxy server Settings to be enabled.

1. You manually set up the proxy server.
2. You may be using some networking tool, such as a VPN program. Such programs may automatically write proxy address information.

I know you've tried a few schemes to fix this problem, but no luck. Therefore, I have put together as much of a process as possible for you in the hope that this will help you:

1. Uninstall and delete related VPN programs:

If you do have such networking tools installed, uninstall them to address the root cause of the problem. If you still need to use such a program and do not plan to uninstall it, please refer to the following steps.

2. Run network commands.

Try running these network commands to manually reset the TCP/IP stack, release and renew the IP address, and flush and reset the DNS client resolver cache:

1. In the search box on the taskbar, type Command prompt. The Command Prompt button will appear. To the right of it, select Run as administrator.
2. Enter the following commands one by one and press Enter to execute them:

    netsh winsock reset
   
    netsh int ip reset
   
    ipconfig /release
   
    ipconfig /renew
   
    ipconfig /flushdns
   

After the execution is complete, restart your device to verify that the problem still exists.

3. Update or roll back network drivers:

Outdated or corrupt network drivers can cause a variety of connectivity issues. Try to update your network drivers to the latest version, or if you recently updated them, consider rolling them back to a previous version.

4. Reset the network:

This removes all network adapters and reinstalls them, and restores the network configuration to its original Settings.

Click the Start menu -- Settings -- Network and Internet-- Status -- Network Reset.

5. Check the proxy Settings in the registry:

An incorrect entry in the Windows registry can cause this problem. Be careful when editing the registry, incorrect changes can cause serious problems. If you are familiar with this process, you can:

1. Press Win + R, type regedit, and then press Enter to open the registry editor.
2. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings.
3. Delete content related to "ProxyServer" and "ProxyOverride".
4. Navigate to HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\CurrentVersion\Internet Settings
5. Delete all but the default

Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

I hope this process will help you solve this problem.
