File Explorer

Use the file explorer to browse, upload, and download files. You can work with files in the Documents folder, Pictures folder, and in the local storage folders for apps that you deployed from Visual Studio or the Device Portal.

Kiosk Mode

Available only with the Microsoft HoloLens Commercial Suite.

Enables kiosk mode, which limits the user's ability to launch new apps or change the running app. When kiosk mode is enabled, the Bloom gesture and Cortana are disabled, and placed apps aren't shown in the user's surroundings.

Check Enable Kiosk Mode to put the HoloLens into kiosk mode. Select the app to run at startup from the Startup app dropdown. Click or tap Save to commit the settings.

Note that the app will run at startup even if kiosk mode is not enabled. Select None to have no app run at startup.

1. For criteria applying to the same property - events can satisfy any one of these criteria are shown.
2. For criteria applying to different property - events must satisfy all of the criteria

For example, you can specify the criteria (Task Name contains 'Foo' or 'Bar') AND (Text contains 'error' or 'warning')

Simulation

Using the Windows Device Portal

The Windows Device Portal for HoloLens lets you configure and manage your device remotely over Wi-Fi or USB. The Device Portal is a web server on your HoloLens that you can connect to from a web browser on your PC. The Device Portal includes many tools that will help you manage your HoloLens and debug and optimize your apps.

Setting up HoloLens to use Windows Device Portal

1. Power on your HoloLens and put on the device.
2. Perform the bloom gesture to launch the main menu.
3. Gaze at the Settings tile and perform the air tap gesture. Perform a second air tap to place the app in your environment. The Settings app will launch after you place it.
4. Select the Update menu item.
5. Select the For developers menu item.
6. Enable Developer Mode.
7. Scroll down and enable Device Portal.

Connecting over Wi-Fi

1. Connect your HoloLens to Wi-Fi.
2. Look up your device's IP address.
   • Find the IP address on the device under Settings > Network & Internet > Wi-Fi > Advanced Options.
3. From a web browser on your PC, go to https://
   • The browser will display the following message: "There’s a problem with this website’s security certificate". This happens because the certificate which is issued to the Device Portal is a test certificate. You can ignore this certificate error for now and proceed.

Connecting over USB

1. Install the tools to make sure you have Visual Studio Update 1 with the Windows 10 developer tools installed on your PC. This enables USB connectivity.
2. Connect your HoloLens to your PC with a micro-USB cable.
3. From a web browser on your PC, go to http://127.0.0.1:10080.

Connecting to an emulator

You can also use the Device Portal with your emulator. To connect to the Device Portal, use the toolbar. Click on this icon:

• Open Device Portal: Open the Windows Device Portal for the HoloLens OS in the emulator.

Creating a Username and Password

The first time you connect to the Device Portal on your HoloLens, you will need to create a username and password.

1. In a web browser on your PC, enter the IP address of the HoloLens. The Set up access page opens.
2. Click or tap Request pin and look at the HoloLens display to get the generated PIN.
3. Enter the PIN in the PIN displayed on your device textbox.
4. Enter the user name you will use to connect to the Device Portal. It doesn't need to be a Microsoft Account (MSA) name or a domain name.
5. Enter a password and confirm it. The password must be at least seven characters in length. It doesn't need to be an MSA or domain password.
6. Click Pair to connect to Windows Device Portal on the HoloLens.

If you wish to change this username or password at any time, you can repeat this process by visiting the device security page by either clicking the Security link along the top right, or navigating to: https:///devicesecurity.htm.

Security certificate

If you are see a "certificate error" in your browser, you can fix it by creating a trust relationship with the device.

Each HoloLens generates a unique self-signed certificate for its SSL connection. By default, this certificate is not trusted by your PC's web browser and you may get a "certificate error". By downloading this certificate from your HoloLens (over USB or a Wi-Fi network you trust) and trusting it on your PC, you can securely connect to your device.

1. Make sure you are on a secure network (USB or a Wi-Fi network you trust).
2. Download this device's certificate from the "Security" page on the Device Portal.
   • Either click the Security link from the top right list of icons or navigate to: https:///devicesecurity.htm
3. Install the certificate in the "Trusted Root Certification Authorities" store on your PC.
   • From the Windows menu, type: Manage Computer Certificates and start the applet.
   • Expand the Trusted Root Certification Authority folder.
   • Click on the Certificates folder.
   • From the Action menu, select: All Tasks > Import...
   • Complete the Certificate Import Wizard, using the certificate file you downloaded from the Device Portal.
4. Restart the browser.
