Device Serial Number Windows 10

[Piren Cobrin]

The Device ID (Advertising ID) is a distinctive number associated with a device. This number is important for technicians and engineers when trying to find solutions to ongoing issues. And it will change if you reset or install new Windows.

A hardware ID is a vendor-defined identification string that Windows uses to match a device to a driver package. A hardware ID identifies a device and indicates that any driver package that declares it can work with a device that has that ID for some degree of functionality. In most cases, a device has more than one hardware ID associated with it. Typically, a list of hardware IDs is sorted from most to least suitable for a device. For example, the list of conceptual hardware IDs for a device might look like:

Hardware IDs are reported to the Plug and Play Manager (PnP) by a device's enumerator (its bus driver). Typically, when the author of a bus driver needs to create a new hardware ID for a device it will report to PnP, it will use one of the following generic formats:

The number of characters of a hardware ID, excluding a NULL terminator, must be less than MAX_DEVICE_ID_LEN. This constraint applies to the sum of the lengths of all the fields and any \\ field separators in a hardware ID. For more information, see the Operations section of IRP_MN_QUERY_ID.

Root enumerated devices are special in that they can be created using APIs where a hardware ID can be provided. Root enumerated devices with hardware IDs sharing generic namespaces such as ROOT\SYSTEM may conflict and result in an yellow-bang error icon in Device Manager when updating Windows.

You can prevent this by using a unique namespace for each driver that has a root enumerated device. For a USB or system device, instead of using ROOT\USB or ROOT\SYSTEM" use ROOT\[COMPANYNAME]\[DEVICENAME]. Then, before installing, check to see if the devnode is already present.

The list of hardware IDs can also be obtained programmatically by retrieving the DEVPKEY_Device_HardwareIds property on a device. For example, that property can be retrieved with APIs such as IoGetDevicePropertyData, SetupDiGetDeviceProperty, or CM_Get_DevNode_Property.

The list of hardware IDs that this routine retrieves is a REG_MULTI_SZ value. The maximum number of characters in a hardware list, including a NULL terminator after each hardware ID and a final NULL terminator, is REGSTR_VAL_MAX_HCID_LEN. The maximum possible number of IDs in a list of hardware IDs is 64.

Computers that are equipped with Wireless Wide Area Network (WWAN) capability have an IMEI number that is assigned to the wireless device. This information is required when activating the computer with your WWAN carrier.

On Windows 10, the computer model number can come in handy in many situations. For example, the model number can make it easier to find the correct hardware upgrade (such as memory, storage drive, monitor, and power supply). Or if you must troubleshoot a problem or contact technical support. It can also come in handy to catalog the device in an inventory.

Although manufacturers typically use stickers or print the information on the chassis of their laptops or desktops, Windows 10 allows you to check the model number and the serial number (service tag) using the System Information app, Command Prompt, and PowerShell.

This identification number can be helpful when you want to download the correct device drivers. That's because if you know the hardware ID, then you can use it to search for a specific driver online.

The Command Prompt is an incredible tool that helps you access most apps, configure system settings, and troubleshoot device issues. You can also perform other tricks with it, such as checking the hardware IDs for your devices.

At the moment, every time a new device is connected it creates a new com port. This means that each time we change the device we have to re-configure the serial port, baud rate, ecc. and this is VERY time consuming (also, we actually don't know what will happen when we reach COM256. Will it go back to 1? Will it show some error?).

Since this use case is very specific, is there a way to force a COM port number on a fixed USB port? The PC is only used for that test line, so if forcing a COM number would create issues elsewhere it would not be an issue.

I found out the solution, you have to add a registry binary key to make the PC ignore serial numbers of the device. This means that for a device with the same VID and PID (same manufacturer and product) the unique serial numbers will be ignored and the same com port will be used.

Many Bluetooth devices use a Serial Port Profile (SPP). Some examples of devices using an SPP include GPS receivers, EM sensors, and some barcode/RFID scanners. This article explains how to pair a device using an SPP to a Windows device with Bluetooth. It also outlines how to locate an assigned COM port number.

Your Windows instance comes with an EBS volume that serves as the root volume. If your Windows instance uses AWS PV or Citrix PV drivers, you can optionally add up to 25 volumes, making a total of 26 volumes. For more information, see Amazon EBS volume limits for Amazon EC2 instances.

Depending on the instance type of your instance, you'll have from 0 to 24 possible instance store volumes available to the instance. To use any of the instance store volumes that are available to your instance, you must specify them when you create your AMI or launch your instance. You can also add EBS volumes when you create your AMI or launch your instance, or attach them while your instance is running.

When you add a volume to your instance, you specify the device name that Amazon EC2 uses. For more information, see Device names for volumes on Amazon EC2 instances. AWS Windows Amazon Machine Images (AMIs) contain a set of drivers that are used by Amazon EC2 to map instance store and EBS volumes to Windows disks and drive letters. If you launch an instance from a Windows AMI that uses AWS PV or Citrix PV drivers, you can use the relationships described on this page to map your Windows disks to your instance store and EBS volumes. If your Windows AMI uses Red Hat PV drivers, you can update your instance to use the Citrix drivers. For more information, see Upgrade PV drivers on EC2 Windows instances.

The following PowerShell script lists each disk and its corresponding device name and volume. It is intended for use with instances built on the AWS Nitro System, which use NVMe EBS and instance store volumes.

Right-click the gray pane labeled Disk 1, and then select Properties. Note the value of Location and look it up in the tables in Map disk devices to device names. For example, the following disk has the location Bus Number 0, Target Id 9, LUN 0. According to the table for EBS volumes, the device name for this location is xvdj.

The following table describes how the Citrix PV and AWS PV drivers map non-NVMe instance store volumes to Windows volumes. The number of available instance store volumes is determined by the instance type. For more information, see Instance store volume limits for Amazon EC2 instances.
