I can see is more devices in Windows 7 64 bit device manager

I just got a laptop (2.67 GHz quad core i7).  It had Windows 7 Pro 64 bit responsible.  I tried to clean up some unwanted 'free' software.  When I went to the Device Manager to check on a device, nothing was in the window.  There are no hidden devices.   Everything seems to work, but I don't see all the devices in the window.

Hello

What is the brand and model of the computer?

When you open Device Manager, no devices appear in the list. Instead, a blank window appears.

This problem occurs if the Plug-and-Play service has been disabled (disabled).

Method 1:

To resolve this problem, set the startup type for Plug-and-Play on automatic. To do this, follow these steps:

a. Click Start and run, type services.msc, and then click OK.

b. double-click Plug-and-Play. If you receive a Configuration Manager message, click OK.

c. in the Startup Type list, click Automatic, and thenOK.

d. close Services.

e. restart the computer.

Method 2:

The other reason, Device Manager may be empty is because there are some security issues with the registry key.

Note: serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article:http://windows.microsoft.com/en-US/windows7/Back-up-the-registry

a. click on start-> Run-> type regedit.exe.

b. search for the following: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum

c. now right-click on Enum and click Permissions.

d. click on the Add button and type everyone, and then click OK. Check the box allow next to the reading for everyone. Now click on add and enter the system. Check the box allow next to the read and full control to the system.

e. the two check boxes under allow must be selected when you highlight the system. Also be sure to click on the Advanced button after adding the two users and select Reset entry permission on all child objects with the entries displayed here and that apply to child objects. Click OK.

f. restart your computer now and check if the problem persists.

Method 3:

Perform a SFC scan on your computer. Consult the following link:
