AVD Clients: Choose and Deploy

Users connect to Azure Virtual Desktop through client applications. The new Windows App is replacing legacy clients and works on every platform. Learn how to choose, deploy, and troubleshoot AVD clients across Windows, macOS, iOS, Android, and web browsers.

How users connect to AVD

☕ Simple explanation

Think of AVD clients as remote controls for your cloud desktop.

Your desktop runs in Azure, but you need something on your device to see it and interact with it — like a TV remote control. The Windows App is Microsoft’s latest universal remote. It works on your laptop, phone, tablet, or even just a web browser. You open it, sign in, and your cloud desktop appears on your screen.

AVD client applications establish an RDP connection to session hosts through the AVD Gateway. The client handles rendering the remote desktop on the local display, capturing input (keyboard, mouse, touch), and managing device redirection (cameras, printers, USB devices).

Windows App is the new unified client that replaces the legacy Remote Desktop clients (MSRDC). It provides a single application for connecting to AVD, Windows 365 Cloud PCs, Microsoft Dev Box, and Remote Desktop Services — across Windows, macOS, iOS, Android, and web.

Client options — what is available

ClientPlatformsKey FeaturesStatus
Windows AppWindows, macOS, iOS, AndroidUnified client, multi-monitor, device redirection, RDP ShortpathCurrent — recommended
Web clientAny modern browserNo install needed, works anywhereCurrent — always available
Remote Desktop client (MSRDC)Windows, macOSLegacy client, full feature setBeing replaced by Windows App
Remote Desktop app (Store)WindowsStore version of legacy clientDeprecated — use Windows App

Windows App — the recommended client

Windows App is the primary client going forward. Key capabilities:

  • Multi-monitor support: Span your remote desktop across multiple monitors
  • Dynamic display resolution: Adapts to window size and DPI changes
  • Device redirection: Cameras, microphones, USB devices, printers, clipboard
  • RDP Shortpath and Multipath support: UDP transport for better performance
  • Multiple service support: One app for AVD, Windows 365, Dev Box, and RDS
  • Workspace feed subscription: Subscribe by URL or email-based discovery
  • Teams media optimisation: Offloads audio/video processing to the client

Web client — zero install

The AVD web client at client.wvd.microsoft.com provides browser-based access:

  • Works in Edge, Chrome, Safari, and Firefox
  • No installation or admin rights required on the device
  • Good fallback for locked-down devices or BYOD scenarios
  • Limitations: no multi-monitor, limited device redirection, no RDP Shortpath

🌐 Priya’s BYOD solution: “Half our NomadTech contractors use personal devices we don’t manage. We can’t ask them to install software. The web client is perfect — they open a browser, sign in with their credentials, and they’re in. For our full-time staff with company devices, we deploy Windows App through Intune.”

💡 Exam tip: Web client limitations

The web client is convenient but has feature gaps compared to native clients. If an exam question asks about multi-monitor support, USB redirection, or RDP Shortpath — the web client does NOT support these. You need a native client (Windows App) for full functionality.

However, the web client does support clipboard redirection, audio playback, and basic file transfer.

Subscribing to a workspace feed

Before users can see their desktops and apps, they must subscribe to a workspace feed:

MethodHow It Works
URL subscriptionUser enters https://rdweb.wvd.microsoft.com/api/arm/feeddiscovery
Email discoveryUser enters their email address — the client discovers the feed automatically
Auto-subscriptionConfigure via Intune or Group Policy to subscribe automatically on sign-in

Auto-subscription is recommended for managed environments — users open Windows App and their desktops appear without manual configuration.

Deploying AVD clients

Deployment methods

MethodBest ForDetails
Microsoft StoreBYOD, self-serviceUsers install Windows App from the Store
Microsoft IntuneManaged corporate devicesPush Windows App as a required or available app
SCCM/MECMOn-premises managed devicesDeploy MSI package through task sequences
Direct download (MSI)Manual deployment, testingDownload from Microsoft and install manually
Group Policy (MSI)AD-joined devices at scaleDeploy MSI via software installation GPO
WingetDeveloper/IT pro self-servicewinget install Microsoft.WindowsApp

🌐 Priya’s deployment matrix: “We have staff in 12 countries on every platform. Windows and macOS devices get Windows App pushed through Intune. iOS and Android devices get it through the App Store and Google Play. Contractors use the web client. Ben’s creative team on Macs needed the native client for multi-monitor support with their external displays.”

Client auto-update

Windows App updates automatically by default. For enterprise environments, you can control updates:

  • Microsoft Store: Updates managed through Store policies
  • Intune: Deploy new MSI versions as app updates
  • Update ring: Windows App supports update channels (Public, Insider)
Client Comparison: Windows App vs Web Client
FeatureWindows App (Native)Web Client (Browser)
Installation requiredYes — native app installNo — browser only
Multi-monitorYes — full multi-monitor supportNo — single browser window
RDP Shortpath / MultipathYes — UDP transportNo — TCP only
Device redirection (USB, cameras)Yes — full device redirectionLimited — clipboard and audio only
Teams media optimisationYes — offloads to clientNo — runs in session host
Dynamic resolutionYes — adapts to window/display changesLimited
Offline workspace cachingYes — remembers subscriptionsNo — requires connection
Best forPrimary daily use on managed devicesBYOD, fallback, locked-down devices

Troubleshooting client connections

Common issues and solutions

SymptomLikely CauseSolution
”We couldn’t find any resources”User not assigned to an application groupVerify app group assignment in AVD portal
Black screen after connectingSession host GPU issue or profile failureCheck FSLogix logs, GPU driver compatibility
”Connection attempt failed”Network connectivity or gateway issueRun msrdcw://connect?diagnostics in Windows App
Slow connection / high latencyUsing TCP instead of UDPEnable RDP Shortpath, check UDP connectivity
Frequent disconnectionsNetwork instabilityEnable RDP Multipath for automatic failover
”Access denied”Conditional Access policy blockingCheck CA policies for device compliance

Client log locations

ClientLog Location
Windows App (Windows)%localappdata%\Packages\Microsoft.WindowsApp_*\LocalState\DiagOutputDir
Web clientBrowser developer tools (F12) console
macOS client~/Library/Containers/com.microsoft.rdc.macos/Data/Library/Logs
ℹ️ Deep dive: Connection diagnostics URL

Windows App supports a special diagnostics URL that tests connectivity to the AVD service:

msrdcw://connect?diagnostics

Opening this URL launches a connectivity diagnostic that checks:

  • DNS resolution for AVD endpoints
  • TCP connectivity to the gateway
  • UDP connectivity for RDP Shortpath
  • WebSocket connectivity
  • Certificate validation

This is invaluable for troubleshooting — run it before escalating any connection issue.

Question

What is the Windows App and what is it replacing?

Question

What are the limitations of the AVD web client compared to the native Windows App?

Click or press Enter to reveal answer

Answer

The web client does not support: multi-monitor, RDP Shortpath (UDP transport), full device redirection (USB, cameras), Teams media optimisation, or dynamic resolution. It runs entirely in the browser with TCP-only connectivity.

Question

How does a user subscribe to an AVD workspace feed?

Click or press Enter to reveal answer

Answer

Three methods: (1) URL subscription — enter the feed discovery URL manually, (2) Email discovery — enter email address and the client finds the feed, (3) Auto-subscription — configured via Intune or GPO so desktops appear automatically.

Knowledge Check

Priya has contractors in 5 countries using personal devices that NomadTech does not manage. The contractors need access to AVD desktops but cannot install software on their devices. What client should Priya recommend?

Knowledge Check

Mia's radiology team reports that Teams video calls are choppy and laggy when working through AVD. They use the web client. What should Mia do?
