Windows 11 migration for SMEs: a plan that doesn't replace half your laptops

· 8 min read · SilverData team

Windows 10 lost official support on 14 October 2025. Since then, laptops running "the ten" no longer receive security patches — and yet in most SMEs coming to us this year, part of the team is still on Windows 10 "because it works and why change it". It works until the first accounting software breakpoint, until the first insurer's audit, and until the first piece of ransomware that finds itself a known, unpatched hole.

This article is about how a 10–50 person SME can migrate to Windows 11 at the company's pace, not in a panic — without signing a 60-thousand invoice "because every supplier suddenly has a deal on". We're writing from the perspective of companies we've helped sort this out in the last six months.

What October 2025 actually changed

Support ended, but the system didn't explode. Windows 10 still boots in the morning and still prints invoices. Three things did change, though — and each of them, if ignored, costs more than the migration itself.

This isn't a "we still have a year" situation. It's an "every month without a plan raises your risk" situation — but also "you don't have to do it tomorrow in a panic".

What it looked like at one of our clients — 34 people, 28 laptops, 12 problems

At one of our clients, a 34-person logistics company in Western Poland, the starting picture was this: 28 laptops in the company, all Windows 10 Pro, 2–6 years old. A compatibility scan showed that 16 of them met Windows 11 requirements "out of the box", and 12 did not — mostly missing TPM 2.0, a few with too old a processor (Intel 7th gen, which Microsoft doesn't allow on Win11).

Their existing IT vendor's first offer: "let's replace those 12 laptops, PLN 4,500 net apiece, plus rollout, licences and configuration — PLN 78,000 total, ready in a month". Management nearly signed it.

We did a short audit of those 12 machines with them. The result: 7 laptops were actually used only occasionally (warehouse, reception, visitor desk), so a cheap PLN 2,500 device or a hand-me-down from another employee would do. 3 laptops were less than 3 years old and simply needed TPM enabled in BIOS (the chip was there, just switched off). That left 2 units for actual replacement. The migration cost dropped from PLN 78,000 to PLN 19,500, and the rollout took 6 weeks instead of 4 — but with no outages and no lost data.

This isn't a story about "the cheap version of the same thing". It's a story about the default "let's replace everything" offer being fat in the middle almost every time.

Three realistic paths for every laptop

In practice, every single device has one of three paths. The key is to deliberately pick a path per laptop, not "let's swap the fleet".

There's a fourth path worth remembering: move the user onto Windows 365 Cloud PC or AVD and keep the old laptop as a "terminal" to a cloud desktop. Rarely pays off financially in an SME, but in specific scenarios (remote work from Ukraine, seasonal staff, heavy apps on weak hardware) it can be a clean answer.

A decision matrix — pick a path in 15 minutes per laptop

Before you start negotiating quotes, put four columns in a spreadsheet for every employee and their device. It takes 15 minutes per laptop and saves tens of thousands of złoty.

  1. Windows 11 compatibility. Run Microsoft's free "PC Health Check" or use Microsoft's list of supported CPUs. Mark YES/NO. For a handful of machines, check the BIOS — TPM 2.0 is often shipped disabled.
  2. Device role. "Heavy" (ERP + all-day work) or "light" (reception, warehouse, kiosk)? Heavy + incompatible hardware = replacement. Light = rotate a hand-me-down in.
  3. Age and condition. A 5+ year old laptop with a swelling battery and a worn-out keyboard is due for replacement regardless of Win11. You're buying new hardware "because of the migration", but you'd do it in a year anyway.
  4. Critical deadline. When does a patch or an app actually run out? For most SMEs the deadline isn't "December 2025" but "when our accounting software stops working". Order the queue by that, not by hardware age.

Once the table is filled in, 80% of decisions are obvious and countable. You end up with 2–3 edge cases worth discussing with the IT vendor — and those are what you actually discuss, not the whole fleet at once.

How to run it without paralysing the company

A Windows 10 → 11 migration isn't a "let's do it all over a weekend" project. It's an exercise you run at the pace of 4–8 weeks, in waves of 5–10 devices, starting with the least critical.

The point of that sequence: when something breaks, it doesn't break at the CEO's desk. The first breakage is discovered by IT or a pilot. Not by accounting on day 25 of the month.

Traps SMEs walk into

We've seen a few repeat mistakes this year. Writing them down so nobody's surprised.

Where to start tomorrow

If Windows 11 has been hanging over your company but nobody has the time to untangle it, do this — in order:

  1. Send a survey today: "how many laptops do you have, how many are on Windows 10". You'll have the number in 30 minutes.
  2. Run PC Health Check on 3–5 random units. You'll see your compatibility rate — with our clients it ranges from 45% to 80%.
  3. Fill the four-column matrix from the section above. 15 minutes per laptop. The rest defaults to "in-place upgrade" — that's free.
  4. Cost the replacement only for the units where it's actually justified. Almost always less than you assumed.
  5. Schedule waves 0 and 1 this month. The rest across the next quarter in waves of 5–10.

Windows 11 isn't a revolution. It's just a mandatory update you're better off having behind you before the first customer audit and before the first vulnerability that starts being weaponised. You do it at the company's pace, not in a panic.

If you want someone to walk through that spreadsheet with you and leave with a clear plan after one meeting — we help SMEs do this kind of exercise regularly. The first conversation is free and takes half an hour.

You don't have to replace half your fleet. You have to decide, in 15 minutes per laptop, which of the three columns each one belongs in.
