What to do if the Device Manager isn’t displaying data?

Device Manager is a useful Windows Control Panel application that allows users to manage device drivers and disable certain hardware components. If you notice that your device manager is not displaying any data, this user guide may help.

If your actual Device Manager is completely blank or empty, there are two possible reasons: either you are running into a critical Windows service that may be disabled, or you may have registry permissions for many devices.

What to do if Device Manager goes blank?

Enable plug-and-play Windows service

The plug-and-play service ensures that your computer is running properly. To check if it’s running:

1. Open the chat window by pressing Windows + R.
2. Type services.msc in Start and press Enter to access the Windows Services Manager.
3. Double-click and make sure the Startup option is set up, and the Type is set to Automatic. If you think that the service is currently disabled, click Start.
4. Check if the issue with your device manager is resolved.

If it is not, move to the second solution.

Change registry permission

1. Open a chat window.
2. Type regedit in the special empty field and press Enter to open the registry editor window. Then access the key here: hkey_local_machinesystemcurrentcontrolsetenum.
3. Use the right mouse button and enum to get permissions. If the list of fields “Group” or “Names” is empty, then this is the problem! There should be two names here: System and All.
4. Click the Add button and enter each one, then click OK. Also, check the “Allow” box that is positioned next to “Read”.
5. Check the boxes “Allow”, “Read” and “Full access” with “System”.
6. When selecting a system, the checkboxes in the “Allow” section should always be checked.
7. Click “OK”.

Re-register the DLLs

To fix this particular problem with a blank or white Device Manager window, you can re-register the following three data DLLs and see if that helps.

• vbscript.dll
• jscript.dll
• mshtml.dll

Press Windows + R to launch the chat window. A confirmation popup will appear on the screen.

Edit registry

Our next solution is about making some changes to the registry entries.

1. Open the dialog box by pressing the Windows + R.
2. Double-tap the toolbar area to display the three functions listed below: Explorer, Shell Browser, and Web Browser.
3. Click on each entry, then find the specific “ITBarLayout” file on the right side of the editor window after registering.
4. Right-click it and search for “Delete” (you should do this each time you log in from the explorer toolbar using a shell browser and a web browser).
5. Close the Device Registry Editor.
6. Reload the window and then run Manager, kindle to see if you still have problems.
