On May 8, 2026, Microsoft renamed Windows 365 Frontline to Windows 365 Flex. The new name better reflects what the product has become in practice: a Cloud PC service for any worker who does not need a dedicated PC, not just shift workers or frontline staff. The rename is purely cosmetic, and licensing, features, and pricing remain unchanged.
This article explains the two deployment modes, the features that go with each, and what to consider when sizing your license count.
Why the rename to Windows 365 Flex
Windows 365 Frontline was originally positioned for shift-based and frontline workers sharing devices on-site. Since launch, Microsoft has seen it adopted much more broadly: part-time employees, seasonal staff, external contractors, developers who need temporary environments, and any role that only needs occasional or task-based access to a Windows desktop. The “Flex” name better represents that broader audience.
If you already have Windows 365 Frontline licenses, there is nothing to do. They continue to work and are simply now called Flex licenses.
The two deployment modes
Windows 365 Flex can be deployed in Dedicated mode or Shared mode, and a single Flex license can be applied to either.
Dedicated mode
Each user gets their own personal Cloud PC, but three users share a single license and only one of them can be active at any given time. This suits shift-based teams, users rotating across time zones, part-timers, and contingent staff who each need their own desktop but never use it at the same time with their teammates.
A few practical notes:
- You can provision up to three Cloud PCs per license, but the maximum concurrent active sessions across your tenant equals the number of licenses purchased. If you buy 10 licenses, you can provision 30 Cloud PCs, but only 10 can be active at the same time.
- Sessions are released automatically when a user signs off, making the seat available to a teammate.
- A concurrency buffer lets you briefly exceed the active session limit a small number of times per day, to absorb scheduling overlaps without failed connections.
- Intelligent prestart learns each user’s typical sign-in time and starts their Cloud PC about 30 minutes before, so the connection feels instant. Cloud PCs power off automatically after sign-out to save resources.
Shared mode
Multiple users share the same underlying Cloud PC, with one active session at a time per shared VM. This is the right fit for customer-facing workers, external contractors, and any role that needs short-duration access to perform a specialized task and does not require data persistence.
By default, the Cloud PC is reset to a clean state when the user signs out, which is what you want for kiosk-style or short-task access. If you do need user-specific settings and app data to persist between sessions, you can enable User Experience Sync (UES), which stores cloud-based application data and Windows settings centrally and replays them on the next sign-in.
Shared mode also pools user storage across the group, so multiple Cloud PCs share a common storage allocation. That keeps sizing and cost predictable for groups where individual storage footprints are small and bursty.
Windows 365 Cloud Apps
Shared mode is also the foundation for Windows 365 Cloud Apps: instead of giving a user a full Cloud PC desktop, you can publish a single Windows application that runs on shared infrastructure. The user only sees the app and does not see a desktop. This is the right tool for exposing a single line-of-business application to someone on a tablet, thin client, or unmanaged device, without handing them an entire virtual desktop.
Licensing and pricing
Nothing changes commercially: Existing Frontline licenses are now Flex licenses with the same SKUs, the same per-user pricing, and the same Microsoft 365 prerequisites. Mixed estates with both Dedicated and Shared mode provisioning policies are supported on the same license pool; when new licenses are added, Dedicated mode Cloud PCs are provisioned first.
License sizing is driven by peak concurrent active sessions (not by the headcount):
- For Dedicated mode, that means you license for peak overlap across the rotating user pool.
- For Shared mode, the number of licenses you assign to a Microsoft Entra group equals the number of shared Cloud PCs available to that group.
Security and compliance
Both Dedicated and Shared modes support Microsoft Purview Customer Key, so newly provisioned Cloud PCs are encrypted with your own key once the capability is enabled in Purview. The standard Windows 365 management surface (Intune, Microsoft Entra groups, Conditional Access) applies the same way as in Windows 365 Enterprise.
Current limitations
A few capabilities are not yet supported on Windows 365 Flex:
- No in-place resize of a Cloud PC: In Windows 365 Enterprise, administrators can change the size of an existing Cloud PC (vCPU, RAM, storage) on the fly through a remote action. This is not yet available on Flex, so the size you choose at provisioning is the size you keep until the Cloud PC is reprovisioned.
- No cross-region disaster recovery: Windows 365 Enterprise can replicate Cloud PCs to a secondary Azure region so they can be brought back up if the primary region has an outage. This option is not available on Flex, which means a regional outage affects Flex Cloud PCs until the region is restored.
- Shared mode is currently limited to the Azure Global Cloud: Shared mode is not yet offered in sovereign clouds such as Azure Government or Azure China. If your workloads have to run in a sovereign cloud for compliance or data-residency reasons, you can still use Dedicated mode there, but Shared mode is not an option.
It is worth checking your target Azure regions and any sovereign-cloud requirements against this list before standardizing on Shared mode for a sensitive workload.
