Sometimes, windows may just return blank results. We have already sen how to fix blank System Restore or Control Panel boxes and blank Windows Updates panel too.

If your Device Manage appears blank, Microsoft suggests you try this:

1. Open Registry Editor

2. Maximize the "HKEY_LOCAL_MACHINE" window.

3. Scroll down to "SYSTEM\CurrentControlSet\Enum"

4. With "Enum" selected click the "Security", "Permissions" menu.

At this point you will probably notice there are no permissions on this key.

5. Click "Add".

6. Add the group "Everyone" and the user "SYSTEM".

7. Select "Everyone" and check "Read" ONLY!

8. Select "SYSTEM" and check "Full Control".



9. Click the "Advanced" button at the bottom of the window.

10. On the Advanced window check "Reset permissions on all child objects..."

11. Click "OK"

12. On the warning window click "Yes"

13. Close REGEDT32.

Hope it helps!
