How to Hide or Show Device Performance and Health in Windows Security

The Device Performance and Health page in Windows Security serves as a built-in diagnostic dashboard, providing a snapshot of your system's critical components, including storage capacity, battery life, device drivers, and the Windows Time service. This section is valuable for identifying hardware issues and ensuring your device is running optimally. However, in managed environments or on shared computers, administrators may wish to hide this page to simplify the interface, restrict user access to sensitive hardware information, or enforce compliance standards. This guide covers how to hide or show the Device Performance and Health page using Group Policy and the Windows Registry. 

Method 1: Using Group Policy

The Group Policy Editor provides a straightforward way to control the visibility of the Device performance & health page. This method is available in Windows editions that include the Local Group Policy Editor, such as Windows 11 Pro, Enterprise, and Education.

1. Press Win + R, type gpedit.msc, and press Enter to open the Local Group Policy Editor.

2. Navigate to the following path:

Computer Configuration > Administrative Templates > Windows Components > Windows Security > Device performance and health

3. In the right pane, double-click the policy named Hide the Device performance and health area.

4. To hide the page, select Enabled. To show the page, select Not Configured or Disabled.

5. Click Apply, then OK.

Method 2: Using Registry Editor

If the Local Group Policy Editor is unavailable, such as on Windows 11 Home, the same setting can be configured through the Windows Registry.

1. Press Win + R, type regedit, and press Enter. If the User Account Control prompt appears, click Yes.

2. Navigate to:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender Security Center\Device performance and health

3. If the Device performance and health key does not exist, right-click Windows Defender Security Center, select New > Key, and name it Device performance and health.

4. Select the Device performance and health key, right-click in the empty space, select New > DWORD (32-bit) Value, and name it UILockdown.

5. Double-click UILockdown and set the value:

• 1 to hide the page
• 0 to show the page

6. Click OK, close the Registry Editor, and restart the computer for the change to take effect.

Conclusion

In conclusion, hiding or showing the Device Performance and Health page in Windows Security is a useful administrative option for managed, shared, or restricted Windows environments. It gives administrators control over the user interface without affecting the system’s actual security protection. The change is reversible, so the default view can be restored whenever needed.
