# System Requirements and Considerations
<a name="client-system-requirements"></a>

The WorkSpaces Applications client requires the following:
+ Follow the principle of least privilege when launching the WorkSpaces Applications client. The client should only run with the level of privilege required to complete a task. 
+ Client requirements
  + Windows client
    + Operating system — Windows 10 (32-bit or 64-bit), Windows 11 (64-bit)
    + Microsoft Visual C\$1\$1 2019 version 14.20.xx Redistributable or later. For more information, see the [Latest Microsoft Visual C\$1\$1 Redistributable Version](https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170) in the Microsoft Support documentation.
    + RAM — 2 GB minimum
    + Hard drive space — 200 MB minimum
  + macOS client
    + Operating system — macOS 13 (Ventura), macOS 14 (Sonoma), macOS 15 (Sequoia)
    + Hard drive space — 200 MB minimum
+ Local administrator rights — Used if you want to install the WorkSpaces Applications USB driver for USB driver support.
**Note**  
Local administrator rights are not supported for the macOS client.
+ An WorkSpaces Applications image that uses the latest WorkSpaces Applications agent or agent versions published on or after November 14, 2018. For information about WorkSpaces Applications agent versions, see [WorkSpaces Applications Agent Release Notes](agent-software-versions.md).
+ The client supports UDP as well as the default TCP-based streaming over NICE DCV. For more information about NICE DCV and UDP, see [Enabling the QUIC UDP transport protocol](https://docs.aws.amazon.com/dcv/latest/adminguide/enable-quic.html). If you want to enable UDP streaming for the client, make sure you meet the following requirements. If you don't meet the following requirements, the client will default back to TCP-based streaming.
  + Your Stack has been configured to prefer UDP in the **Streaming Setting Experience** section. For more information, see [Create an Amazon WorkSpaces Applications Fleet and Stack](set-up-stacks-fleets.md).
  + Your network allows UDP traffic on port 8433 for the AWS IP Ranges. For more information, see [AWS IP address ranges](https://docs.aws.amazon.com/general/latest/gr/aws-ip-ranges.html).
  + You are using the latest base image when creating your fleet. For more information, see [WorkSpaces Applications Base Image and Managed Image Update Release Notes](base-image-version-history.md).
  + Your end users are using the latest client. For more information, see [Supported clients](https://clients.amazonappstream.com/).

**Note**  
We recommend an internet connection for WorkSpaces Applications client installation. In some cases, the client can't be installed on a computer that is not connected to the internet, or USB devices might not work with applications streamed from WorkSpaces Applications.
