For more information about other valid Flags values, see ActivateDeviceEx. The Device Emulator contains the emulator technologies featured in Windows CE 5.0. By using the Device Emulator, you can run emulated-based images created by Windows CE 5.0 without installing Platform Builder, its platform development tool. Here's how to open Device Manager from the Command Prompt (cmd) in Windows 10, 8, 7, Vista, & XP. This command-line method is the fastest way there.

This function opens a device for reading, writing, or both. An application indirectly invokes this function when it calls the CreateFile function to open special device file names.
Parameters
Return Values
This function returns a handle that identifies the open context of the device to the calling application. If your device can be opened multiple times, use this handle to identify each open context. This identifier is passed into the XXX_Read (Device Manager), XXX_Write (Device Manager), XXX_Seek (Device Manager), and XXX_IOControl (Device Manager) functions. This function returns zero if the device cannot be opened.
Remarks
When this function executes, your device should allocate the resources that it needs for each open context and prepare for operation. This might involve preparing the device for reading or writing and initializing data structures it uses for operation.

Device Manager is a Control Panelapplet in Microsoft Windows operating systems. It allows users to view and control the hardware attached to the computer. When a piece of hardware is not working, the offending hardware is highlighted for the user to deal with. The list of hardware can be sorted by various criteria.[1]
For each device, users can:
Device Manager was introduced with Windows 95 and later added to Windows 2000. In NT-based versions, it is included as a Microsoft Management Console snap-in.
Types of icons[edit]Disabled device[edit]
A disabled device has either been manually disabled by a user or by some way of error. In Windows 95 through XP, this is denoted by a red X. In Windows Vista and Windows 7, this was replaced by a grey downward pointing arrow in the lower right-hand corner of the device's icon.
Hardware not working properly[edit]
There are many reasons why hardware may not work properly. If Windows recognizes a problem with a device, it is denoted by a black exclamation point (!) on a yellow triangle in the lower right-hand corner of the device's icon.
Hardware not recognized[edit]
Hardware may not be recognized if it is not installed properly or not compatible with the system. This is denoted by a yellow question mark in place of the device's icon.
Device manually selected[edit]
A blue 'i' on a white field in the lower right-hand corner of a Device's icon indicates that the Use automatic settings feature is not selected for the device and that the resource was manually selected. Note that this does not indicate a problem or disabled state.
Error codes[edit]
Device Manager error codes are numerical codes, each accompanied by an error message, which help users determine what kind of issue Windows is having with a piece of hardware.[2][3]
Driverquery command[edit]
The
driverquery [4]command-line program generates lists of installed devices and drivers, similar to the Device Manager's output, which the user may view on-screen or redirect to a file. This is useful for note-taking and for reporting problems to remote third parties such as technical support personnel. The program has switches to control the output detail and format, including an /fo switch with csv parameter to generate output in comma-separated values format, suitable for importing into a spreadsheet application such as Microsoft Excel.[5]See also[edit]References[edit]
