Device Portal for Windows Desktop
Windows Device Portal lets you view diagnostic information and interact with your desktop over HTTP from a browser window. You can use Device Portal to do the following:
- See and manipulate a list of running processes
- Install, delete, launch, and terminate apps
- Change Wi-Fi profiles, view signal strength, and see ipconfig
- View live graphs of CPU, memory, I/O, network, and GPU usage
- Collect process dumps
- Collect ETW traces
- Manipulate the isolated storage of sideloaded apps
Set up Device Portal on Windows Desktop
Turn on developer mode
Starting in Windows 10, version 1607, some of the newer features for desktop are only available when developer mode is enabled. For information about how to enable developer mode, see Enable your device for development.
Sometimes, due to network or compatibility issues, developer mode won't install correctly on your device. See the relevant section of Enable your device for development for help troubleshooting these issues.
Turn on Device Portal
You can enable Device Portal in the For developers section of Settings. When you enable it, you must also create a corresponding username and password. Do not use your Microsoft account or other Windows credentials.
Once Device Portal is enabled, you will see web links at the bottom of the section. Take note of the port number appended to the end of the listed URLs: this number is randomly generated when Device Portal is enabled but should remain consistent between reboots of the desktop. If you'd like to set the port numbers manually so that they remain permanent, see Setting port numbers.
These links offer two ways to connect to Device Portal: over the local network (including VPN) or through the local host.
Connect to Device Portal
To connet through local host, open a browser window and enter the address shown here for the connection type you're using.
- Local Network:
https://<IP address of the desktop>:<PORT>
HTTPS is required for authentication and secure communication.
If you are using Device Portal in a protected environment, like a test lab, in which you trust everyone on your local network, have no personal information on the device, and have unique requirements, you can disable the Authentication option. This enables unencrypted communication, and allows anyone with the IP address of your computer to connect to and control it.

More Device Portal options
Registry-based configuration for Device Portal
If you would like to select port numbers for Device Portal (such as 80 and 443), you can set the following regkeys:
UseDynamicPorts: A required DWORD. Set this to 0 in order to retain the port numbers you've chosen.
HttpPort: A required DWORD. Contains the port number that Device Portal will listen for HTTP connections on.
HttpsPort: A required DWORD. Contains the port number that Device Portal will listen for HTTPS connections on.
Under the same regkey path, you can also turn off the authentication requirement:
- This controls both the basic auth requirement for each connection and the redirect from HTTP to HTTPS.
Command line options for Device Portal
From an administrative command prompt, you can enable and configure parts of Device Portal. To see the latest set of commands supported on your build, you can run
sc start webmanagementor
sc stop webmanagement
- Turn the service on or off. This still requires developer mode to be enabled.
-Credentials <username> <password>
- Set a username and password for Device Portal. The username must conform to Basic Auth standards, so cannot contain a colon (:) and should be built out of standard ASCII characters e.g. [a-zA-Z0-9] as browsers do not parse the full character set in a standard way.
- This resets the SSL certificate cache used for HTTPS connections. If you encounter TLS connection errors that cannot be bypassed (as opposed to the expected certificate warning), this option may fix the problem for you.
-SetCert <pfxPath> <pfxPassword>
- See Provisioning Device Portal with a custom SSL certificate for details.
- This allows you to install your own SSL certificate to fix the SSL warning page that is typically seen in Device Portal.
