How to Fix the “Windows Could Not Detect This Network’s Proxy Settings” Error on Windows 10
Restarting your router and computer is the first step to take if you receive the error “Windows could not find this network’s proxy setting”. This will close all open applications and reset proxy settings to default. For most users, this should resolve the issue.
If that doesn’t help then you should try disabling any firewalls, antivirus software or VPN software that might interfere with your Internet connection. You can turn off each application through the settings and turning it off one at a time. Once you’ve disabled all these apps, try reconnecting to the Internet and see if the problem persists.
If you can’t resolve the issue using any of these solutions, you may want to consider a full system restore in Windows. This will restore the default network settings and eliminate any other changes that might be creating the issue. You can do this by navigating to the Control Panel and then clicking on “Internet Options.” Once you’re inside the window, uncheck the boxes labeled Automatically detect settings and Use a proxy server for your LAN. This method only affects your current user account. If you are using a shared computer, you might need to repeat this process for other users. You can also disable proxy settings via the Registry Editor, but this is a little more involved and can potentially cause problems in the future.
