Setup and installation

Download and install the version of the client that you need as follows:

To install...	Do this
5.x client	Open Amazon WorkSpaces Client Downloads and find the WorkSpaces Windows client. Under Get the latest 64 bit client, choose the Download button.
4.x client	Open Previous Versions. Find the WorkSpaces Windows client version and choose the Download button.
3.x client	Open Amazon WorkSpaces Client Downloads and find the WorkSpaces Windows client. Under Get the latest 32-bit client, choose the Download button.

You have two choices for how to install the Amazon WorkSpaces Windows client application:

• Install just for you. If you choose this option and you share your local machine with other users, the WorkSpaces client application is available only to you. If other users on the machine also want to use the WorkSpaces client application, they must install the application for their own use.

• Install for all users of this machine. If you choose this option, the WorkSpaces client application is available to anyone who logs on to the local machine, including those with Guest accounts.

Installing the WorkSpaces client application for all users requires you to have administrator privileges on your local machine. Depending on how your local machine is configured, you might not have such privileges. In that case, you can install the WorkSpaces client application just for yourself. If you have questions about which option to choose, ask your WorkSpaces administrator for guidance.

When installing the client 4.0+ version, you will have an option to install the USB redirection driver for features like Yubikey U2F redirection support. Use the following procedure to install the USB redirection driver.

To install the USB redirection driver

1. On the Amazon WorkSpaces Setup page, select Install for all users of this machine. Choose Next.

   

2. Select Install driver for USB redirection to enable the USB redirection features (the default setting is not selected). Choose Install. You must have administrator privileges to install the driver.

   

3. To install the client with PCoIP USB redirection, enter and run the following command in an elevated command prompt.

   msiexec.exe /i "[path to msi]" /qn INSTALL_USB="1" ALLUSERS="1"

   To install the client without PCoIP USB redirection, enter and run the following command in an elevated command prompt.

   msiexec.exe /i "[path to msi]" /qn ALLUSERS="1"

If you're having trouble updating your WorkSpaces Windows client application to a newer version, use the following procedure to update your client application.

To update the WorkSpaces Windows client application to a newer version

1. On your local machine, open the Windows search box and enter registry editor to open the Registry Editor (regedit.exe).

2. When asked "Do you want to allow this app to make changes to your device?", choose Yes.

3. In the Registry Editor, navigate to the following registry entry:

   Computer\HKEY_CURRENT_USER\Software\Amazon Web Services. LLC\Amazon WorkSpaces\WinSparkle

4. Delete the SkipThisVersion registry key. When prompted to confirm the deletion, choose Yes, and then close the Registry Editor.

5. If you have not already entered a registration code in the WorkSpaces Windows client application, do so, and then choose Amazon WorkSpaces, Quit Amazon WorkSpaces to close the client application.

6. Restart the WorkSpaces Windows client application. You should be prompted to update the client. Accept the update.

Determine your client version

To see which version of the WorkSpaces client you have, choose Amazon WorkSpaces, About Amazon WorkSpaces, or click the gear icon in the upper-right corner and choose About Amazon WorkSpaces.

Connect to your WorkSpace

To connect to your WorkSpace, complete the following procedure.

To connect to your WorkSpace for 3.0+ clients

1. The first time that you run the client application, you are prompted for your registration code, which is contained in your welcome email. The WorkSpaces client application uses the registration code and user name to identify which WorkSpace to connect to. When you launch the client application later, the same registration code is used. To enter a different registration code, launch the client application, and then choose Change Registration Code at the bottom of the login page.

2. Enter your sign-in credentials in the login screen and choose Sign In. If your WorkSpaces administrator has enabled multi-factor authentication for your organization's WorkSpaces, you are prompted for a passcode to complete your login. Your WorkSpaces administrator will provide more information about how to obtain your passcode.

3. If your WorkSpaces administrator has not disabled the Keep me logged in feature, you can select the Keep me logged in check box at the bottom of the login screen to save your credentials securely so that you can connect to your WorkSpace easily while the client application remains running. Your credentials are securely cached up to the maximum lifetime of your Kerberos ticket.

   After the client application connects to your WorkSpace, your WorkSpace desktop is displayed.

An interruption of network connectivity causes an active session to be disconnected. This can be caused by events such as closing the laptop lid, or the loss of your wireless network connection. The WorkSpaces client application for Windows attempts to reconnect the session automatically if network connectivity is regained within a certain amount of time. The default session resume timeout is 20 minutes, but this timeout can be modified by your network administrator.

Manage your login information (3.0+ clients only)

You can view your registration code and what Region your WorkSpace is in. You can specify whether you want the WorkSpaces client application to save your current registration code, and you can assign a name to your WorkSpace. You can also specify if you want Amazon WorkSpaces to keep you logged in to a WorkSpace until you quit or your login period expires.

To manage your login information for a WorkSpace

1. In the WorkSpaces client application, go to Settings, Manage Login Information.

2. In the Manage Login Information dialog box, you can see the registration code and Region information for your WorkSpace.

3. (Optional) If you want the WorkSpaces client to remember your current registration code, select the Remember Registration Code check box.

4. Under Saved registration codes, select the WorkSpace that you want to name.

5. In the WorkSpace name box, enter a name for the WorkSpace.

6. (Optional) If you want WorkSpaces to keep you logged in until you quit or your login period expires, select the Keep me logged in check box.

7. Choose Save.

Client views

You can switch to full screen mode by choosing View, Enter Full Screen (3.0+ clients) in the client application menu.

While in full screen mode, you can switch back to window mode by moving the pointer to the top of the screen. The client application menu is displayed, and you can choose View, Leave Full Screen (3.0+ clients) in the client application menu.

You can also toggle full screen mode by pressing Ctrl+Alt+Enter.

Client language

You can select the language displayed by the client by performing the following steps.

Note

The WorkSpaces client applications support Japanese. However, Japanese WorkSpaces are available only in the Asia Pacific (Tokyo) Region.

To select the client language

1. Depending on which client you're using, do one of the following.

   If you're using...	Do this
   3.0+ client	In the WorkSpaces client application, go to Settings, Change Language.

2. Enter your desired language in the Select a language list and choose Save.

3. Restart the client.

Display support

WorkSpaces Value, Standard, Performance, Power, PowerPro, Graphics.g4dn, GraphicsPro.g4dn, and GraphicsPro bundles support a maximum of four displays and a maximum resolution of 3840x2160 (ultra-high definition, or UHD). The maximum supported resolution depends on the number of displays, as shown in the following table.

Displays	Resolution
2	3840x2160
4	1920x1200

Note

• You can only extend the display. You cannot duplicate the display. Duplicating the display will cause your session to be disconnected.

• Graphics bundles support only a single monitor configuration with a maximum resolution of 2560x1600.

The WorkSpaces client application extracts the Extended Display Information Data (EDID) of all attached displays and determines the best compatibility match before starting the session. If you have a high pixel density (high DPI) display, the client application automatically scales the streaming window according to your local DPI settings. For better maximum resolution with high DPI displays, see Enabling high DPI display for WorkSpaces.

To use multiple monitors with WorkSpaces

1. Configure your local machine to use multiple monitors. For more information, see How to use multiple monitors in Windows 10 in the Microsoft documentation.

2. Start the WorkSpaces client application and log in to your WorkSpace.

3. Depending on which client you're using, do one of the following:

   If you're using...	Do this
   3.0+ client	Choose View, Enter Full Screen On All Displays. You can also toggle full screen mode by pressing Ctrl+Alt+Enter.

Your WorkSpace should now be extended across your displays. Whichever display you have designated as your primary display is also the primary display in WorkSpaces when you enter full screen mode.

Note

Using full screen mode on only some of the displays in a multiple monitor setup isn't possible. You can, however, press the Windows logo key + Up Arrow or use the maximize button in the upper-right corner of the WorkSpaces window to maximize the WorkSpaces client window on a display without extending the WorkSpace to the other displays.

Proxy servers

If your network requires you to use a proxy server to access the internet, you can enable your WorkSpaces client application to use a proxy for HTTPS (port 443) traffic. The WorkSpaces client applications use the HTTPS port for updates, registration, and authentication.

Note

• The desktop streaming connections to the WorkSpace require ports 4172 and 4195 to be enabled, and do not go through the proxy server.

• Proxy servers that require authentication with sign-in credentials are not supported.

To control the proxy server for 3.0+ clients

By default, the 3.0+ Windows clients use the proxy server that's specified in the device operating system settings. The first time the client is launched, the device operating system proxy server setting is used. If you select another option for the proxy server, that setting is used for subsequent launches of the client. If a proxy server is specified at both the operating system level and in the WorkSpaces client, the client setting is used.

Starting with version 3.0.12 of the Windows client, you can also choose not to use a proxy server.

Note

In versions 3.0.0 through 3.0.11, if you specify a custom proxy server, a "No network" error might appear when you attempt to log in to your WorkSpace. If you want to use a custom proxy server with the Windows client, we recommend upgrading to the latest version.

1. In the WorkSpaces client application, go to Settings, Manage Proxy Server.

2. In the Set Proxy dialog box, select the appropriate options, depending on which version of the 3.0+ client you have.

   • Windows client version 3.1.3 or later — To disable usage of a proxy server, select Don't use proxy server. If you select Don't use proxy server, no proxy server is used when you access the internet.

     To use a proxy server, choose one of the following options, and then choose Save:

     • Use your device operating system settings — This option uses the proxy server settings for your operating system.

     • Customize proxy server for WorkSpaces — Enter the URL or IP address and the port for your custom proxy server.

   • Windows client versions 3.0.12, 3.1.0, and 3.1.2 — To enable or disable usage of a proxy server, select or deselect Use proxy server. If you deselect Use proxy server, no proxy server is used when you access the internet.

     If you've selected Use proxy server, choose one of the following options, and then choose Save:

     • Use your device operating system settings — This option uses the proxy server settings for your operating system.

     • Customize proxy server for WorkSpaces — Enter the URL or IP address and the port for your custom proxy server.

   • Windows client version 3.0.11 or earlier — By default, these versions of the client use the proxy server specified in the device operating system settings. To use a custom proxy server, choose Use proxy server, enter the URL or IP address and the port for the proxy server, and then choose Save.

Command shortcuts

The WorkSpaces Windows client supports the following command shortcuts:

• Ctrl+Alt+Enter—Toggle full screen display

• Ctrl+Alt+F12—Disconnect session

Clipboard support

The clipboard supports a maximum uncompressed object size of 20 MB. For more information, see I'm having trouble copying and pasting.

Note

When copying from a Microsoft Office app, the clipboard only contains the last copied item, and the item is converted into standard format. If you copy content larger than 890 KB from a Microsoft Office app, the app might become slow or unresponsive for up to 5 seconds.

Manage hardware acceleration

Starting with version 5.0.0, hardware acceleration is enabled by default when you're using the Amazon WorkSpaces Windows client application.

Note

If you plan to upgrade to a version between 3.1.4 and 5.0.0, and if you've disabled hardware acceleration for version 3.1.3 or earlier by using the procedure described later in this section, make sure that you re-enable hardware acceleration in Windows by setting the DisableHWAcceleration registry key to 0.
