Device Manager Is Blank or Not Showing Anything? Fix It Now

Troubleshooting a Blank Device Manager in Windows

Device Manager, a crucial Windows utility for managing hardware, can sometimes fail to display any content. This issue, often caused by disabled services or registry permission problems, can lead to various hardware malfunctions. This guide provides solutions to restore Device Manager functionality.

Problem: Device Manager shows nothing.

Solutions:

1. Enable the Plug and Play Service:

The Plug and Play service is essential for hardware recognition. If disabled, Device Manager won't function correctly.

• Open the Windows Services window by typing services.msc in the search bar and pressing Enter.
• Locate the "Plug and Play" service, double-click it, and ensure the "Startup type" is set to "Automatic". If the "Service status" isn't running, click "Start".
• Click "Apply" and "OK" to save changes.

2. Re-register DLL Files:

Unregistered DLL files can cause Device Manager to be blank. Re-registering them might resolve the issue.

• Open Command Prompt as administrator (search for "command prompt," right-click, and select "Run as administrator").

• Execute the following commands, pressing Enter after each:

  <code>regsvr32 vbscript.dll
  regsvr32 jscript.dll
  regsvr32 mshtml.dll</code>

• Check if Device Manager now displays correctly.

3. Grant Full Registry Permissions:

Incorrect registry permissions can prevent Device Manager from working. Adjusting these permissions can fix the problem.

• Press Win R to open the Run window.
• Type regedit and press Enter to open Registry Editor.
• Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum.
• Right-click on "Enum" and select "Permissions".
• Click "Add" to add "Everyone," then check "Allow" for "Read".
• Click "Add" again to add "System," then check "Allow" for "Read" and "Full Control".
• Click "Apply" and "OK". Restart your computer.

Important Note: Before modifying the registry, create a system restore point or back up your registry. Incorrect registry edits can cause serious system problems. Consider using backup software like MiniTool ShadowMaker for comprehensive system protection.

These steps should resolve a blank Device Manager. Remember to back up your system before making any registry changes.
