original title: WINDOWS 7 DEVICE MANAGER WON'T OPEN

I am trying to open device manager from control panel and get the green progress bar moving slowly across the top, but it never actually finishes and opens device manager.  I am just trying to see my printers, but can't get the DM open.

    Hi johnjjordan,

    Do you get any error message when you try opening the device manager?

    I would suggest you to check in safe mode if you are able to access device manager. In Safe mode; you have access to only basic files and drivers. Refer to the link to start the computer in safe mode –

    http://windows.microsoft.com/en-us/windows7/Start-your-computer-in-safe-mode

    After booting in safe mode, follow the below steps to open device manager -

    1. Click Start and then click on Run.
    2. Type devmgmt.msc and then click Ok.

    If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.

    You may even click on Start and type Device Manager****in the search box displayed and check if you are able to open it from the options displayed in start menu window.

    Hope this helps. Let us know the results.

    Thanks,

    I am using Windows 7 Home. I noted my DVD/CD rom would not work so I tied opening Device Manager to check it.    I also cannot get Device Manager to open.  I can't get it to run from the Start: Run .  I cant get it to run from the control panel.   I can't get Device Manager to open in Safe mode.     I keep getting the message:

    Navigation to the webpage was canceled

    I ran SFC/scannow in Widows Safe mode.  NO errors were reported.

    I restored older backups (Aug. 13, 2010) -- still device manager won't work

    I've run a virus check.  -- still no device manager, same error above.

    There is the file devmgmt.msc in Window/system32 directory.  It is also in a few other locations  on my C: drive.

    What do I need to do to get this to work?

    Thanks, David
