Azure Virtual Desktop vs Windows 365: Which Fits a UK SMB Best?

Once a quarter we have the same conversation with a prospect: “We want our team working from anywhere on company laptops, but the laptops are getting old, expensive to replace, and we cannot keep up with the security patches. Should we move to a cloud desktop?”

The answer is almost always yes. The follow-up question is the tricky one: Azure Virtual Desktop or Windows 365? Both run Windows in Microsoft Azure. Both let staff log in from any device. The names are deliberately confusing. The price difference for a 25-person team can be £20,000 a year.

Here is the honest comparison we give clients, in plain English.

In short: Windows 365 gives each person a fixed, simple Cloud PC for a flat monthly fee, while Azure Virtual Desktop is more flexible and can be cheaper at scale but needs more managing. Here is which one fits a UK SMB, with a worked cost comparison.

First, what are we actually talking about?

Both products give your staff a Windows desktop that runs in Microsoft’s Azure data centre instead of on their laptop. Users connect via a browser or a small Windows app on whatever device they have. The corporate data, software and settings live in the cloud, not on the device.

The benefits are the same for both products:

• Staff can work from any device, including old laptops, iPads or personal machines, without compromising security.
• If a device is lost or stolen, no company data is on it.
• Backups, patching and antivirus are managed centrally.
• New starters can be productive within an hour: just give them login details.

The differences are about how Microsoft charges you and how much engineering work is involved in keeping it running.

What is Windows 365?

Windows 365 (sometimes called “Cloud PC”) is the simpler of the two. You buy a fixed monthly subscription per user. Each user gets a dedicated Windows 11 Cloud PC with a set spec (CPU, RAM, storage). It is always on, always available, and Microsoft handles all the underlying infrastructure.

Pricing in May 2026, in round numbers:

• Business 2 vCPU / 8GB RAM / 128GB: around £30 per user per month
• Business 4 vCPU / 16GB RAM / 256GB: around £45 per user per month
• Business 8 vCPU / 32GB RAM / 512GB: around £75 per user per month

The Business edition is the one most SMBs want. There is also Enterprise, which has more management options but needs Microsoft Intune and a slightly more complex Azure setup.

What you get: a familiar Windows experience, predictable monthly cost, almost no infrastructure to manage. What you give up: any ability to “turn it off overnight” to save money. You pay for the machine 24/7 whether the user is logged in or not.

What is Azure Virtual Desktop?

AVD is the older, more flexible, more complex product. Instead of a fixed monthly price per user, you pay for the underlying Azure resources by the second: virtual machines, storage, bandwidth.

There are two main flavours:

• Personal AVD: each user has their own dedicated VM, similar to Windows 365 but billed by consumption. If you switch the VM off at night, you only pay for storage.
• Pooled AVD (multi-session): one big Windows 11 multi-session VM is shared by many users at once. Far cheaper per user, but every user gets a fresh session at login, so applications need to be installed centrally and personal customisations are limited.

The Windows 11 multi-session model is the trick that makes AVD cheaper than Windows 365. You can comfortably fit 8 to 12 light office users on a single 8-core / 32GB VM, which means the per-user compute cost drops dramatically.

The catch: AVD needs an engineer who understands Azure to set up properly. Image management, FSLogix profile containers, scaling plans, conditional access, networking. None of it is hard if you have done it before, but none of it is trivial if you have not.

The real cost comparison for a 25-person UK SMB

This is where it gets interesting. Let me run the numbers on a real scenario: a 25-person professional services firm, Monday to Friday, 9am to 6pm, light office workloads (Microsoft 365, a CRM, occasional accounting software).

Windows 365 (Business 4 vCPU / 16GB)

25 users x £45 per month = £1,125 per month or £13,500 per year. That is it. No extra Azure costs, no engineering overhead, no scaling plans to manage.

AVD Pooled (multi-session, scaling enabled)

Three 8-core / 32GB VMs sized for 25 users at peak, scaling down to one VM out of hours. Realistically:

• VM compute (45 hours per week active, idle the rest): ~£450 per month
• FSLogix profile storage (Azure Files): ~£80 per month
• Networking, monitoring, backup: ~£100 per month
• Windows licensing (already covered by Microsoft 365 Business Premium): £0

Total: around £630 per month or £7,500 per year. A saving of about £6,000 a year on paper.

So why does anyone choose Windows 365?

Because that £6,000 saving usually evaporates once you add the management costs. AVD needs setup work (typically £3,000 to £6,000 one-off), regular image updates, occasional scaling tuning, and someone who can troubleshoot when a user’s session will not load. That is real engineering time. For most SMBs we work with, paying the Windows 365 premium and getting that headache out of their lives is the right call.

The exception is firms with predictable shift patterns, very tight margins, or a large number of part-time users where Windows 365’s per-user pricing becomes punishing.

When AVD is the right answer

Pick AVD if:

• You have shift-based or part-time staff where many users share a small pool of machines. AVD’s multi-session model is far cheaper here.
• Your team works strict office hours and you can switch VMs off overnight and weekends without anyone noticing.
• You already have an Azure tenant and an MSP comfortable with Azure. Most of the AVD complexity disappears when someone else owns it.
• You need special hardware sizes (GPU for CAD, very high memory for engineering software) that Windows 365 does not offer cleanly.
• You have 50+ users where the consumption-billing savings start to dwarf the management overhead.

When Windows 365 is the right answer

Pick Windows 365 if:

• You want a predictable monthly bill with no surprises, billed alongside your other Microsoft 365 subscriptions.
• You have fewer than 50 users with standard office workloads.
• Your team works variable hours, including evenings, weekends or international hours where “switching off at 6pm” would frustrate people.
• You do not have an MSP comfortable with Azure (or you have one but would rather they spent their time on other things).
• You want each user to have a fully personal Windows desktop they can customise, install apps on, and treat as their own.

What about hybrid? Can we run both?

Yes, and this is what we usually end up recommending for clients above 30 staff.

The typical pattern: AVD pooled for the bulk of the office team (cheap, multi-session, locked-down apps), Windows 365 for the leadership team, finance, and anyone who needs a personal customisable desktop. You get the best of both worlds: low per-user cost for the majority, full flexibility where it matters.

The shared infrastructure underneath (Microsoft Entra, Intune, conditional access, FSLogix) works for both, so there is no double management overhead.

What about Microsoft 365 licensing?

Both products need Windows 11 Enterprise rights. Those come included in:

• Microsoft 365 Business Premium (£19.10 per user per month) for under-300-employee businesses
• Microsoft 365 E3 or E5 for larger organisations
• Windows 365 Business includes the Windows 11 licence for that Cloud PC if your users do not already have one

For 99% of UK SMBs we work with, Business Premium is the right base licence. It also brings Intune, Entra ID Plan 1, Defender for Business, and a long list of other things you genuinely need for a cloud-first business.

The questions we ask before recommending one over the other

When a client asks us to scope a cloud desktop project, these are the questions we go through:

1. How many users, and what are their working patterns? Full-time vs part-time, office hours vs always-on, single user vs shared shifts.
2. What software do they run? Standard Microsoft 365 is easy. Specialist line-of-business apps need testing. CAD, video editing or accounting software with hardware dongles need careful design.
3. What is the existing IT environment? Are we replacing physical PCs, an old terminal server, or migrating from a different cloud desktop provider?
4. What is the budget and tolerance for variable bills? A predictable £13,500 a year is easier to defend at board level than a “somewhere between £6k and £12k depending on usage” answer, even if the latter averages lower.
5. Who is going to look after it? If the answer is “you, our MSP” then either works. If the answer is “we have an internal IT person who does not know Azure” then Windows 365 is safer.

A worked example: 18-person law firm in Lichfield

We migrated a client like this last year. They had aging Dell laptops, a remote-working policy that was not really working, and a cyber insurance renewal that was about to require multi-factor on every machine.

We considered AVD pooled, but the lawyers wanted dedicated machines they could personalise, and the support staff were on different hours to the partners. We went with Windows 365 Business 4 vCPU / 16GB across the board. The migration took three weeks. Total cost: £9,720 per year for the cloud desktops, plus the existing Microsoft 365 Business Premium licences.

Two years on, they have not replaced a single laptop. New starters get set up in a morning. The old “I cannot access X from home” tickets have disappeared. And the cyber insurance premium went down at renewal.

Frequently asked questions

Is Windows 365 the same as Azure Virtual Desktop?

No. Both give your team a Windows desktop in the cloud, but Windows 365 is a fixed monthly price per user, while Azure Virtual Desktop is billed by usage and is more flexible but more complex to run.

Which is cheaper, AVD or Windows 365?

On paper AVD is often cheaper if your team works set hours and you switch the machines off overnight. Once you add the management overhead, Windows 365 frequently works out better value for a typical SMB.

Can we run both together?

Yes, and for firms above about 30 staff that is often the best answer: pooled AVD for the main team, Windows 365 for people who need a personal, always-on desktop.

Do we still need a Microsoft 365 licence?

Yes. Both need Windows 11 Enterprise rights, which come with Microsoft 365 Business Premium for most SMBs, so that is usually the right base licence.
