Are you receiving the message “Microsoft Edge can’t be opened using the Built-in Administrator account. Sign in with a different account and try again” when you try to launch Microsoft Edge in Windows 10?

This problem can occur when you sign in to Windows using the special built-in Administrator account. Windows applies additional security restrictions to this account, and some applications may not work as expected when the required User Account Control (UAC) settings are not configured.

In this guide, we explain why this message appears and how to configure the appropriate Windows security policy to resolve it. We also cover the alternative Registry procedure for Windows 10 Home users, who normally do not have the Local Security Policy editor.

Why Can’t Microsoft Edge Open Using the Built-in Administrator Account?

Windows includes a special account named Administrator. It is different from an ordinary user account that belongs to the Administrators group.

The built-in Administrator account has a special security configuration. Depending on the Windows security policy, it can run applications with a full administrative token rather than using the normal User Account Control approval process.

Modern Windows applications use security features that expect an appropriate user security context. When the built-in Administrator account is not configured for Admin Approval Mode, an application may refuse to launch and display a warning.

Microsoft’s User Account Control (UAC) feature helps prevent unauthorized changes to Windows by controlling how applications receive administrative permissions.

Common reasons for this error

• You are signed in using the built-in Windows Administrator account.
• The policy for Admin Approval Mode for the built-in Administrator account is disabled.
• The Windows security configuration does not match the requirements of the application.
• A local or domain security policy is controlling the UAC settings.
• The computer is using a customized Windows installation or administrative configuration.

Before You Start – Identify Your Windows 10 Edition

The configuration method depends on your Windows edition.

To check your Windows edition:

1. Press Windows + R.
2. Type winver.
3. Press Enter.
4. Check the Windows version and edition information displayed.

Method 1: Fix the Problem Using Local Security Policy in Windows 10 Pro and Enterprise

This is the recommended configuration method for supported Windows editions that include the Local Security Policy editor.

You need to enable the following security policy:

User Account Control: Admin Approval Mode for the Built-in Administrator account

Step 1: Open Local Security Policy

1. Sign in to Windows using an account that has administrative permissions.
2. Click the Windows Start button.
3. Type secpol.msc in the search box.
4. Click Local Security Policy in the search results.
5. If Windows displays a permission prompt, approve it.

You can also open the Run dialog by pressing Windows + R, entering secpol.msc and pressing Enter.

Step 2: Navigate to Local Policies and Security Options

In the Local Security Policy window, follow this path:

Security Settings
   └── Local Policies
         └── Security Options

1. Expand Local Policies in the left-side panel.
2. Select Security Options.
3. Wait for the security policies to appear in the right-side panel.

Step 3: Find the Built-in Administrator Account Policy

Look for the following policy name:

User Account Control: Admin Approval Mode for the Built-in Administrator account

This setting controls whether the built-in Administrator account uses Admin Approval Mode.

Step 4: Enable the Security Policy

1. Double-click User Account Control: Admin Approval Mode for the Built-in Administrator account.
2. The policy properties window will open.
3. Select Enabled.
4. Click Apply.
5. Click OK.

When this setting is enabled, the built-in Administrator account uses Admin Approval Mode. Administrative operations are subject to the configured UAC approval behaviour.

Step 5: Verify the General UAC Policy

For Admin Approval Mode to operate as intended, also check the general UAC policy:

User Account Control: Run all administrators in Admin Approval Mode

This policy is normally enabled by default. It should not be disabled as a workaround for this Edge error.

To check it:

1. Remain in Local Security Policy > Local Policies > Security Options.
2. Find User Account Control: Run all administrators in Admin Approval Mode.
3. Open the policy properties.
4. Check that it is set to Enabled.
5. If this is a company-managed computer, do not change a centrally managed setting without approval from your IT administrator.

Step 6: Restart Windows

1. Save your work and close all open applications.
2. Click Start.
3. Select Power.
4. Click Restart.
5. After Windows restarts, sign in again using the built-in Administrator account.
6. Try opening Microsoft Edge.

Expected result: If the issue was caused by the disabled Admin Approval Mode policy, enabling it and restarting Windows should resolve the account-related launch restriction.

Method 2: Fix Windows 10 Home Using Registry Editor

Windows 10 Home generally does not include the Local Security Policy editor. Therefore, the secpol.msc method may not be available.

Microsoft documents a corresponding Registry setting for Admin Approval Mode for the built-in Administrator account. Windows 10 Home users can configure this value using Registry Editor.

Step 1: Open Registry Editor

1. Press Windows + R.
2. Type regedit.
3. Press Enter.
4. If User Account Control asks for permission, select Yes.

Step 2: Navigate to the Windows System Policy Registry Key

Navigate to the following Registry location:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System

You can also copy the path above and paste it into the Registry Editor address bar.

Step 3: Back Up the System Registry Key

1. Right-click the System key in the left panel.
2. Select Export.
3. Choose a safe location.
4. Save the file with a name such as Windows-UAC-System-Backup.reg.

This gives you a backup of the selected Registry key before making the change.

Step 4: Find or Create the FilterAdministratorToken DWORD

In the right-side panel, look for a value named:

FilterAdministratorToken

If the value already exists:

1. Double-click FilterAdministratorToken.
2. Set its Value data to 1.
3. Make sure the Base is set to Hexadecimal or Decimal. The value 1 is the same in either base.
4. Click OK.

If the value does not exist:

1. Right-click an empty area in the right-side panel.
2. Select New.
3. Choose DWORD (32-bit) Value.
4. Name it exactly:

FilterAdministratorToken

5. Double-click the newly created value.
6. Set Value data to 1.
7. Click OK.

Important: The correct Registry value is FilterAdministratorToken, with a DWORD value of 1. Do not create a different value with a similar name.

Step 5: Verify the Registry Configuration

Confirm that the Registry location and value are correct:

Step 6: Restart Windows and Test Microsoft Edge

1. Close Registry Editor.
2. Save any open work.
3. Restart Windows.
4. Sign in using the built-in Administrator account.
5. Open Microsoft Edge.

If the issue was caused by the disabled built-in Administrator Admin Approval Mode setting, this change should allow the account to use the configured approval mode.

Important: Do You Need to Change the UIPI Registry Value?

The older version of this article also instructed users to navigate to the following Registry subkey:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\UIPI

It then suggested changing the Default value to 1.

This additional change is not included in the corrected procedure. Microsoft’s current documentation identifies FilterAdministratorToken as the Registry value corresponding to the built-in Administrator Admin Approval Mode policy. It does not require changing the UIPI Default value for this configuration.

Do not modify unrelated Registry values simply because they appeared in an older troubleshooting guide.

Should You Change the User Account Control Slider?

The original article also recommended checking the User Account Control notification slider.

You can open the UAC settings using these steps:

1. Click Start.
2. Type UAC in Windows Search.
3. Select Change User Account Control settings.
4. Review the current notification level.

For normal Windows security, keep UAC enabled at its recommended default level unless your organization’s security policy specifies otherwise.

Changing the notification slider is not a substitute for enabling the specific built-in Administrator Admin Approval Mode policy. Do not lower UAC or disable it to bypass the Edge error.

Method 3: Use a Normal Windows Administrator Account Instead

If you only need to browse the internet, access email or use Microsoft Edge, you do not normally need to sign in using the built-in Administrator account.

A safer approach is to create or use a separate Windows account and assign administrator permissions only if required.

How to create another Windows user account

1. Open Windows Settings.
2. Select Accounts.
3. Open Family & other users or the available other-user account settings.
4. Select Add someone else to this PC.
5. Follow the instructions to create the account.
6. Sign out of the built-in Administrator account.
7. Sign in using the new account.
8. Open Microsoft Edge and test it.

For everyday use, a standard account is generally preferable. If you need administrative permissions, Windows can prompt you for credentials from an administrator account.

Method 4: If the Error Continues After Changing the Policy

If Microsoft Edge still cannot open after enabling the correct setting, check the following items before making further Registry changes.

1. Confirm the correct account is being used

Make sure you are testing the same built-in Administrator account for which the policy was configured. A normal account with administrator membership is not the same as the built-in Administrator account.

2. Check whether the computer is domain-managed

If your computer belongs to a company domain or is managed through Group Policy, an administrator may have configured security settings centrally. Local changes may be overwritten when Group Policy refreshes.

3. Check the policy again

On Windows editions with Local Security Policy, verify that the built-in Administrator Admin Approval Mode policy is Enabled and that the general Run all administrators in Admin Approval Mode policy is not disabled.

4. Restart the computer

Restart Windows after changing the security policy or Registry setting. Do not rely only on signing out and signing back in.

5. Repair Microsoft Edge if there is a separate browser problem

If Edge still crashes or refuses to launch after the account-related restriction is resolved, the browser may have another problem. Follow our separate troubleshooting guide:

How to Reset Microsoft Edge in Windows 10 When Things Are Broken

That guide covers browser updates, extensions, cache, settings reset and the Windows Repair option.

How to Restore the Original Registry Setting

If you need to reverse the Windows 10 Home Registry change, you can restore the original configuration.

1. Press Windows + R.
2. Type regedit and press Enter.
3. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System.
4. Find FilterAdministratorToken.
5. If you created the value specifically for this change, you can delete it to return to the default configuration, or set its data to 0.
6. Restart Windows.

If the setting is managed by an organization, consult your IT administrator before reversing it.

Frequently Asked Questions (FAQs)

1. Why can’t Microsoft Edge be opened using the built-in Administrator account?

The built-in Administrator account has a special Windows security configuration. If Admin Approval Mode for this account is disabled, some applications may refuse to launch in that security context.

2. What is Admin Approval Mode?

Admin Approval Mode is a User Account Control feature that allows Windows to control how administrative operations receive elevated permissions. It helps prevent applications from automatically running with unrestricted administrative privileges.

3. How do I enable Admin Approval Mode for the built-in Administrator account?

On Windows editions with Local Security Policy, open secpol.msc, navigate to Local Policies > Security Options, find the built-in Administrator Admin Approval Mode policy and set it to Enabled. Restart Windows.

4. How can Windows 10 Home users fix this issue?

Windows 10 Home users can use Registry Editor. Navigate to the System policy Registry key and set the DWORD value FilterAdministratorToken to 1. Back up the Registry before making the change and restart Windows afterward.

5. What is the FilterAdministratorToken Registry value?

It is the Registry value that controls whether the built-in Administrator account uses Admin Approval Mode. A value of 1 enables the setting, while 0 disables it.

6. Do I need to change the UIPI Default Registry value?

No. The documented Registry configuration for this specific policy uses FilterAdministratorToken. The additional UIPI Default change in some older guides is not required for this procedure.

7. Should I disable User Account Control to fix Microsoft Edge?

No. Disabling UAC reduces Windows security and is not the recommended solution. Configure the specific built-in Administrator Admin Approval Mode policy instead.

8. Is the built-in Administrator account the same as a normal administrator account?

No. The built-in Administrator is a special Windows account. A normal user account can belong to the Administrators group while still operating under the usual UAC security model.

9. Do I need to restart Windows after changing the policy?

Yes. Restart Windows after changing the Local Security Policy or the corresponding Registry value so the new configuration can take effect.

10. Is this procedure suitable for Windows 11?

The built-in Administrator Admin Approval Mode policy also exists in supported Windows 11 configurations, but Windows 11 may have different security features and interface details. Check the applicable Microsoft documentation and use the instructions for your exact Windows version.

11. Is it safe to browse the internet using the built-in Administrator account?

It is not recommended for everyday browsing. The built-in Administrator account has extensive privileges. Use a standard user account for normal activities and reserve administrative accounts for tasks that require elevated permissions.

Quick Summary – Windows 10 Edge Built-in Administrator Fix

Conclusion

The message “Microsoft Edge can’t be opened using the built-in Administrator account” is related to Windows account security and User Account Control configuration.
