LAN Proxy Settings Greyed Out? Fixes That Work

If the LAN proxy settings in Windows are greyed out, it usually means a group policy, a registry setting, or third-party software is forcing a proxy configuration. You can fix it by editing the registry, adjusting local group policy, or removing the conflicting software.

Why the LAN Proxy Settings Are Greyed Out

Windows gives you proxy controls in Settings > Network & Internet > Proxy and in the older Internet Options > Connections > LAN settings dialog. When those options appear dimmed, Windows is telling you that a higher authority has locked the setting. The most common causes are:

• Group Policy: A domain administrator or a local policy has set a proxy that users cannot change.
• Registry modifications: The ProxySettingsPerUser value is set to 0, which makes proxy settings apply to the whole machine and disables the per-user UI.
• Third-party software: Antivirus suites, VPN clients, or parental-control apps often install a driver or service that takes over proxy configuration.
• Malware: Some malicious programs deliberately lock proxy settings to redirect traffic.

Knowing which cause applies to you is the first step. If you are on a company or school computer, the policy may be intentional—contact your IT administrator before making changes. On a personal machine, you can usually regain control with the methods below.

How to Check What Is Blocking the Settings

Before editing anything, find out what is actually forcing the proxy. Open a Command Prompt (Win+R, type cmd) and run:

reg query "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyEnable

If the output shows ProxyEnable 0x1, a proxy is currently enabled. Next, check the machine-wide policy:

reg query "HKLM\Software\Policies\Microsoft\Windows\CurrentVersion\Internet Settings"

If that key exists and contains values like ProxySettingsPerUser or ProxyServer, a policy is in play. Also check the local group policy editor (only in Pro/Enterprise editions): run gpedit.msc, navigate to User Configuration > Administrative Templates > Windows Components > Internet Explorer, and look for a policy named “Make proxy settings per-machine.” If it is set to Enabled, that explains the greyed-out controls.

Fix 1: Set ProxySettingsPerUser Back to 1

The most common fix for a personal computer is to restore the per-user proxy setting. This registry value tells Windows whether proxy settings apply to the current user only (1) or to all users (0). When it is 0, the Settings and Internet Options proxy boxes are greyed out.

1. Press Win+R, type regedit, and press Enter.
2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\Internet Settings.
3. Look for a DWORD named ProxySettingsPerUser. If it exists, double-click it and change the value to 1.
4. If the key does not exist, right-click the Internet Settings folder, choose New > DWORD (32-bit) Value, name it ProxySettingsPerUser, and set it to 1.
5. Close the Registry Editor and restart your browser or the whole PC.

If that key was missing, adding it with a value of 1 should restore the proxy UI. If the key was already 1, the problem lies elsewhere.

Fix 2: Remove Group Policy Restrictions

If your Windows edition includes the Local Group Policy Editor, you can disable the policy that locks proxy settings. This is a common culprit on machines that were previously part of a domain or that had a temporary policy applied.

1. Press Win+R, type gpedit.msc, and press Enter.
2. Go to User Configuration > Administrative Templates > Windows Components > Internet Explorer.
3. Find the policy named Make proxy settings per-machine (not per user). Double-click it.
4. Set it to Not Configured or Disabled, then click OK.
5. Close the editor and restart the computer.

Note that this policy only appears in Windows Pro, Enterprise, or Education editions. Windows Home does not include gpedit.msc, so you would use the registry method instead.

Fix 3: Check for Third-Party Software Interference

Many security and privacy tools automatically configure the system proxy. For example, some antivirus suites enable a “web protection” feature that routes traffic through a local proxy server (often at 127.0.0.1). VPN clients may also set a proxy for split-tunneling. When these apps are running, they can lock the proxy settings to prevent accidental changes.

To see if such software is involved, open the app’s settings and look for proxy-related options. Disable any “web filtering,” “secure DNS,” or “proxy” feature, then check if the LAN settings become accessible. If they do, the software was the cause. You can also temporarily uninstall the program to confirm, then reinstall it with the proxy feature turned off.

Fix 4: Scan for Malware That Locks Proxy Settings

Malware sometimes modifies the registry to force a proxy server so it can intercept web traffic. If you have not installed any proxy-related software and the settings are greyed out, a scan is a good idea. Use Windows Defender (built into Windows 10 and 11) or a reputable on-demand scanner. Run a full scan, then check the registry keys mentioned earlier. If the malware removed the ProxySettingsPerUser value or added a ProxyServer entry, cleaning the infection may restore your control.

Frequently Asked Questions

Why are my proxy settings greyed out even though I am the administrator?

Being an administrator does not bypass group policy or registry restrictions. The settings are greyed out because a policy or a software component has taken precedence over user input. You need to change the policy or registry value, not just “run as administrator.”

Can I edit the registry if I have Windows Home?

Yes, the registry method works on all Windows editions. Windows Home simply lacks the Local Group Policy Editor, so you cannot use gpedit.msc. The registry fix (setting ProxySettingsPerUser to 1) is the primary solution for Home users.

Will changing the registry break anything?

Changing ProxySettingsPerUser from 0 to 1 only affects how proxy settings are stored. It does not delete any existing proxy configuration. If a system-wide proxy was set by an IT department, changing this value may make the proxy appear in your user settings, but it will not disable the proxy itself. Always back up the registry before making changes.

What if the proxy settings are greyed out but I need to use a proxy?

If a policy is forcing a proxy, you may not need to change it—the proxy is already active. To verify, check the effective proxy by running netsh winhttp show proxy in Command Prompt. If you need a different proxy, you must first unlock the settings using the methods above, then enter your desired proxy address.

Why did my proxy settings become greyed out after a Windows update?

Windows updates occasionally reset certain policy values or introduce new default settings. If a recent update coincided with the issue, check the ProxySettingsPerUser registry value and the group policy editor. Some updates also re-enable “automatic proxy detection,” which can make the manual settings appear unavailable.
