Unlock 2 Fixes for UUID Type Is Not Supported

Troubleshooting the "UUID Type Is Not Supported" Windows Login Error

Are you locked out of your Windows account with the frustrating "UUID type is not supported" error? This guide provides solutions to resolve this issue.

The error, often seen when logging in with a new user account, arises from a communication problem between the Group Policy Client Service (GPSVC) and the Winlogon service. Let's explore how to fix it.

Solution 1: Force GPSVC to Run Independently

This solution involves modifying the registry to ensure GPSVC starts as a separate process, avoiding conflicts. Important: Before making any registry changes, back up your system using a reputable backup tool (like MiniTool ShadowMaker, for example).

1. Open the Run dialog (Win R).
2. Type regedit and press Enter to open the Registry Editor.
3. Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\gpsvc
4. Right-click the gpsvc key, select Permissions, then Advanced.
5. Click Change to select the account taking ownership (often your administrator account). Use the Find Now button to locate it.
6. In the Advanced Security Settings window, check "Replace owner on subcontainers and objects," then click Apply.
7. Open Command Prompt as administrator.
8. Run this command: reg add "HKLM\SYSTEM\CurrentControlSet\Services\gpsvc" /v Type /t REG_DWORD /d 0x10 /f

This should resolve the conflict and allow GPSVC to communicate correctly with Winlogon.

Solution 2: Adjust Group Policy Loopback Processing (Windows Pro/Enterprise/Education Only)

This method involves modifying a Group Policy setting. Note: This solution is only applicable to Windows 10/11 Professional, Enterprise, and Education editions. Windows Home users should skip this step.

1. Open the Run dialog (Win R).
2. Type gpedit.msc and press Enter to open the Local Group Policy Editor.
3. Navigate to: Computer Configuration\Administrative Templates\System
4. Double-click Group Policy.
5. Find Configure user Group Policy loopback processing mode.
6. Select Enabled, then click Apply and OK.

After applying these changes, try logging in with your newly created user account. Remember the importance of regular system backups to protect your data.
