  • Hi,

    This behavior occurs if the Plug and Play service is turned off (disabled).

    Method 1:

    To resolve this behavior, set the startup type for Plug and Play to Automatic. To do so, follow these steps:

    1. Click Start, click Run, type services.msc, and then click OK.

     2. Double-click Plug and Play. If you receive a Configuration Manager message, click OK.

     3. In the Startup Type list, click Automatic, and then click  OK.

     4. Close Services.

     5. Restart the computer.

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

    Important: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

    Method 2:


    1. Click Start-> Run->type in regedit.exe.

    2. Locate the following: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum

    3. Now right-click on Enum and choose Permissions.

    4. Click the Add button and type in Everyone and click OK. Check the Allow box next to Read for Everyone. Now click Add again and type in System. Check the Allow box next to Read and Full Control for System. It should look like this:

    5. Both the check boxes under Allow should be selected when you highlight System. Also be sure to click on the Advanced button after adding both users and selecting Reset permission entries on all child objects with entries shown here that apply to child objects. Click OK.

    Restart your computer now and check if the issue persists.

    Best Regards,
