VDI bandwidth management via GPO policies in the Zoom app

The maximum available bandwidth for thin clients can be configured through GPO policies configured by the administrators. In addition, it is also possible to set bandwidth throttling policies that apply exclusively to office equipment, so home users can take full advantage of all the features provided by personal networks by implementing these policies.

The following topics are covered in this article:

  • MSI bandwidth settings
  • Web bandwidth settings
  • Policy bandwidth settings
  • How to change the value “Office” or “Home” on the thin client
    • Windows
    • macOS
    • Linux

Requirements for VDI bandwidth management through GPO policies

  • Ownership or administrative rights of the account
  • Building a virtual desktop infrastructure

MSI bandwidth settings

This can be done by the administrator either through the installer or by modifying the registry (HKCU or HKLM) with the keys and values ​​listed below:

SOFTWAREPoliciesZoomZoom MeetingsGeneral
  • BandwidthLimitUp – In the Send Bandwidth setting, you can specify how much bandwidth you want to send at a time in kbps.
  • BandwidthLimitDown – There is a minimum value of 800 KB for the maximum receive bandwidth in kbps (should be at least this value).
  • Recommended to ignore bandwidth limits – It is used to ignore and ignore bandwidth limits set by MSI and/or the web. Policy bandwidth settings are not affected by this setting.

Web bandwidth settings

You can find these settings in the account section of the Zoom web portal. MSI bandwidth settings override these settings unless IgnoreBandwidthLimits is set to 1, which overrides MSI bandwidth settings.

  • Depending on the IP address and the rules applied to the IP address, they can be applied.
  • It is possible to set the value to 0 if no bandwidth restrictions apply or exist.

Policy bandwidth settings

It is possible to configure these registry keys on the VDI client to provide policies based on thin client .ini files and they can be configured under the following registry keys:

SOFTWAREPoliciesZoomZoom MeetingsVDIbandwidth
  • Office: These are the settings that need to be set on the thin client to work with the on-premises setup controlled via the .ini file. If you are using the thin client, you can look for the following line in the .ini file in the installation directory:
  • [DeviceLocation]

    A value of 1 for IsInOffice would mean that the Office settings are used if the value of IsInOffice is set to that value.

  • Home:
  • The home settings are used if no .ini file is available, or the IsInOffice value is zero if no .ini file is available.

It should be noted that both the “office” value and the “home” value can accept three types of connections (ICA, UDP and Direct) with “up” and “down” values ​​configured for the available bandwidth are.

GPOBandwidthOverrideWeb=1 is a registry key that allows the values ​​associated with the connection type and location to be used, regardless of whether the value exists under the location or connection type key. Since the default value is 0, there is no bandwidth limit if the value is not configured if left at 0.

*Note: There is a small difference in the implementation of the .ini file for Linux, including the “eLux” distribution. A new line must be added to the ZoomMedia.ini file in the setup/ica/ZoomMedia.ini directory in place of the existing line:

Only one extra line needs to be added:



To set the bandwidth limit for ICA mode when the user is in the office, apply the following bandwidth settings in the policy:

[HKEY_LOCAL_MACHINESOFTWAREPoliciesZoomZoom MeetingsVDIbandwidthofficeica]

How to change the value “Office” or “Home” on the thin client

The thin client setting “Office” or “Home” is determined by the “IsInOffice” value, which is set based on the platform type.


On the Windows Thin Client, create a new file named “bandwidth_config.ini” under the plug-in installation path and add the following two lines:


The default plugin installation path for each platform type is below:

  • AVD: C:Program Files (x86)ZoomWVDMediaPlugin
  • Citrix: C:Program Files (x86)ZoomCitrixHdxPlugin
  • VMware: C:Program Files (x86)ZoomVmwareMediaPlugin


For macOS plugin 5.8.0 and later, the configuration file is located under the ZoomVDI_Config file, located at ~/Library/Application Support/ZoomVDI/ZoomVDI_Config.

Look for the value “ISINOFFICE=” and set the value to 1 or 0.


Similar to Windows, add configuration to the existing ZoomMedia.ini file:



If the GPOBandwidthOverrideWeb policy is set and enabled under SOFTWAREPoliciesZoomZoom MeetingsVDI, only use the bandwidth values ​​from Policy Bandwidth Settings, regardless of whether the value is present under Device Location and Connection Type (our default is 0 and we use the previous bandwidth configuration rules if the value is not set).

How to Check Bandwidth Limit in VDI Statistics Tab

For VDI Client and Plugin 5.10.6 and later, applied bandwidth limits for the plugin and VDI Client can be viewed during a meeting on the VDI Statistics tab.

Access statistics using meeting controls

While in a Zoom meeting on the desktop client, you can view meeting diagnostic information.

  1. Sign in to the Zoom Desktop Client.
  2. Start or join a meeting.
  3. In the meeting controls, click the up arrow next to Start Video/Stop Video.
  4. Click Video Settings.
  5. Click Statistics.
  6. Select the VDI tab.

Access statistics from the main window of the desktop client

  1. Sign in to the Zoom Desktop Client.
  2. Click your profile picture and then click Ideas.
  3. Click Statistics.
  4. Select the VDI tab.

If bandwidth limits are successfully applied, a notice will appear at the bottom of the window: Your IT team has limited the bandwidth available for this meeting at your location.

The bandwidth limits for VDI client and plugin upstream/downstream can be viewed by clicking the exclamation mark.
