The Windows 10 deadline already passed
Let us be blunt. The date most Miami business owners circled has come and gone. Microsoft ended support for Windows 10 on October 14, 2025. After that day, Windows 10 stopped receiving free security patches, feature updates, and standard technical help. Your machines still turn on. They still open email and print invoices. But every month without a patch widens the gap a hacker can walk through.
So the question is no longer whether to move. It is how fast, and how cleanly, you can get your team ready for Windows 11. Some devices upgrade in an afternoon. Others need new hardware. And a few workloads may need a short bridge while you plan. We will walk through each path below, with honest tradeoffs and real 2026 numbers.
Barlop Business Systems has guided South Florida SMBs through every major Windows transition since the 1990s. This one carries a sharper security edge than most, and the businesses moving early are the ones sleeping best.
What “end of support” actually means for your business
End of support is a quiet risk. Nothing breaks on day one. That is exactly why it fools people.
Here is what changed the moment the deadline hit. No more security updates, so newly discovered flaws stay open forever. Bug fixes stop. Microsoft technical support for Windows 10 issues ends. And over time, more software vendors and cloud apps drop testing for the old OS, so crashes and compatibility gaps creep in.
For a regulated Miami business, a law firm, a medical practice, an accounting shop, the compliance angle bites hard. Many cyber insurance policies and frameworks expect supported, patched operating systems. Run an unsupported OS and you may find a claim denied or a renewal quoted much higher.

We are not trying to scare you. We are trying to be straight. An unpatched fleet is a slow leak, not a sudden flood, and slow leaks are the ones sinking businesses, because nobody notices until the damage is done.
Is your hardware ready for Windows 11?
This is where the 2025 transition differs from every prior one. Windows 11 has a real hardware floor, and older PCs simply do not clear it. Before you plan anything, every device needs a compatibility check.
Here is the short list of what Windows 11 requires:
Now the good news. Many business PCs bought in the last five or six years already have TPM 2.0 sitting dormant in the BIOS, switched off from the factory. Turn it on, confirm Secure Boot, and the machine may upgrade for free. So a device you assumed was dead weight might have years of life left. A proper audit tells you which is which, and it saves real money.
The catch? Guessing wrong is expensive both ways. Replace a PC needing only a BIOS toggle and you burned cash. Force Windows 11 onto truly unsupported hardware and Microsoft may withhold updates, which defeats the whole point. This is the part worth handing to a team checking fleets for a living.
Why the security upgrade is the real prize
People treat Windows 11 like a fresh coat of paint. New Start menu, rounded corners, prettier icons. But the point of this release was never the look. It was the security floor.
Those strict hardware requirements exist for a reason. TPM 2.0 and Secure Boot give Windows 11 a hardware root of trust, which makes firmware and boot-level attacks far harder to pull off. Microsoft states machines running Windows 11 with its standard security tools have shown a 60 percent reduction in malware compared to Windows 10 on older hardware. Treat it as a vendor figure, not gospel, and still, the direction is clear.
Share of Windows desktops running Windows 11 by February 2026, per StatCounter data. Windows 10 had dropped to roughly 26 percent.
Cybercriminals love an easy door. And a business still on an unsupported OS is a door propped open with a welcome mat. For a South Florida company handling client records, payment data, or health information, the OS is the foundation everything else sits on. Get it wrong and your firewall, your backups, and your training all inherit the weakness.

Your three paths forward, compared
Every business lands in one of three lanes. Some fleets split across all three. Here is the honest breakdown, including the cost of buying time with Extended Security Updates.
| Path | Best for | Rough cost | The tradeoff |
|---|---|---|---|
| Upgrade in place | PCs already meeting the TPM 2.0 and CPU bar | Little to no license cost; mostly labor and testing | Fastest and cheapest, but only works on compatible hardware |
| Replace the hardware | Older PCs failing the requirements | New business PCs, often $700 to $1,200 each | Best performance and longest runway, higher upfront spend |
| Buy time with ESU | A few machines you cannot move yet | $61 per device Year 1, $122 Year 2, $244 Year 3 | Keeps security patches flowing, but costs climb fast and it only delays the move |
See how the Extended Security Updates price doubles each year? Microsoft designed it deliberately. ESU is a bridge, not a home. It makes sense for a handful of machines tied to specialized software or hardware. It makes no sense as a plan for your whole office.
Most Barlop clients end up with a blend. Upgrade the PCs that qualify, replace the ones that do not, and park a small ESU bridge under the one or two workloads needing a few more months. This mix keeps cash flow sane and the fleet secure.
A practical migration path for your team
A migration gone sideways usually skipped the boring first steps. So here is the sequence we run for South Florida businesses, start to finish.
1. Inventory every device
You cannot plan around machines you forgot you owned. We catalog every desktop, laptop, and remote device, then flag each one as ready, fixable, or replace.
2. Sort compatible from incompatible
Ready machines get scheduled for an in-place upgrade. Fixable ones get a BIOS check for dormant TPM. The rest go on the replacement list.
3. Test your critical apps first
Line-of-business software is where surprises hide. We test your accounting, practice management, or industry apps on Windows 11 before a single user touches it.
4. Back up before you touch anything
No migration starts without a verified backup. If a step fails, we roll back clean. This is non-negotiable, and it is why a solid data backup strategy matters more than ever during a transition.
5. Roll out in waves, not all at once
We move a pilot group first, confirm everything works, then scale to the rest. Waves catch problems small, while they are cheap to fix.
6. Train and support after the switch
Windows 11 moves a few familiar buttons. A short orientation keeps your team productive instead of frustrated on day one.
Why local matters for Miami and Doral businesses
An OS migration is not only a technical project. It is a logistics project. New machines have to be imaged, delivered, and set up. Old ones have to be wiped and recycled responsibly. And someone has to be reachable when a user hits a snag at 8 a.m. on a Monday.
Barlop Business Systems sits right here in Doral, serving Miami-Dade, Broward, and the wider South Florida market for over 40 years. We are family owned, and proud to be a woman and minority owned company rooted in this community since 1983. When a migration needs hands on a device, we are a short drive away, not a ticket in a queue three time zones over.
Hurricane season adds a local wrinkle too. A migration is the perfect moment to confirm your backups, your remote access, and your continuity plan all hold up. We fold the check into the project, because a storm is a bad time to learn your recovery plan had a gap.

What waiting really costs your business
Some owners are tempted to ride Windows 10 a while longer. The machines work, budgets are tight, and the migration feels like a headache. So the plan becomes no plan. We get the instinct. But the math rarely favors delay.
Start with the security exposure. Every month on an unsupported OS is a month of unpatched holes stacking up. Attackers study end-of-life software closely, because they know businesses drag their feet. And ransomware crews do not care how small your company is. They care whether they can get in.
Then there is the productivity drip. Older machines slow down. Newer apps and cloud tools stop testing against Windows 10, so odd bugs and crashes multiply. Your team loses minutes here and there, and those minutes add up across a whole staff over a whole year.
Per-device ESU cost that climbs each year you delay. Buying time for a whole fleet gets expensive fast, and you still have to migrate in the end.
Compliance is the quiet third cost. If your industry expects supported systems, an auditor or an insurer may flag the gap. A denied claim or a failed audit dwarfs the price of a planned migration. So waiting does not remove the cost. It just moves it later and makes it bigger.
The businesses treating this as a project, with a budget and a calendar, come out ahead. The ones treating it as a someday problem tend to migrate anyway, only later, under pressure, and for more money.
Windows 11 features your team will actually use
Security is the headline reason to move. But your staff will notice the day-to-day upgrades too, and those wins are worth naming.
None of these alone justifies a migration. Together, though, they make the move feel like a step forward rather than a chore. And a team on modern, supported tools simply spends less time fighting their computers. That is the hidden return on a well-run upgrade.

A quick self-check you can run today
Want a rough read before you call anyone? You can gather the basics yourself in a few minutes. It will not replace a full audit, but it points you in the right direction.
Start on any Windows 10 PC. Open the free PC Health Check app from Microsoft, or check the system information screen. It tells you whether the machine already clears the Windows 11 bar. Green light? Good, note it as a likely in-place upgrade. Red light? Do not panic yet.
Next, check the age of the device. As a rough rule, business PCs bought in 2019 or later often qualify once TPM is switched on in the BIOS. Anything from 2017 or earlier usually needs replacing. And laptops tend to age faster than desktops, so weigh them a little harder.
Finally, make a simple list. Count how many machines pass, how many are borderline, and how many are clearly too old. Bring that list to a conversation with your IT partner and you have already done the hard part. Barlop can turn a rough count into a real plan, with pricing, a timeline, and no guesswork left in it.
Windows 11 migration FAQ
Can I still use Windows 10 after October 2025?
Yes, the machine keeps working. But it no longer gets free security updates from Microsoft, which leaves it exposed to new threats. Running it for daily business is a real risk, especially if you handle sensitive data.
Is the upgrade to Windows 11 free?
For eligible PCs already running a licensed copy of Windows 10, the upgrade to Windows 11 has been offered at no license cost. The real cost is the labor to check compatibility, test apps, and roll it out safely across your team.
How do I know if my PC can run Windows 11?
The machine needs TPM 2.0, UEFI with Secure Boot, and a supported CPU, roughly Intel 8th gen or AMD Ryzen 2000 series and newer. Many business PCs from the last few years qualify once TPM is switched on in the BIOS. A quick audit confirms it device by device.
What is TPM 2.0 and why does Windows 11 require it?
TPM stands for Trusted Platform Module. It is a secure chip that stores encryption keys in hardware. Windows 11 requires it because it enables stronger protection against boot-level and firmware attacks, which are hard to defend against in software alone.
What are Extended Security Updates and should I buy them?
ESU is a paid program that keeps security patches flowing to Windows 10 past the deadline. For organizations it runs about $61 per device the first year, then doubles each year after. It is a smart bridge for a few stubborn machines, but a costly plan for a whole office.
Can I force Windows 11 onto an unsupported PC?
There are workarounds, but we advise against them for business machines. Microsoft may withhold updates from unsupported installs, which recreates the exact security gap you were trying to close. For a work device, staying within the requirements is the safer call.
Will my current software work on Windows 11?
Most modern apps run fine. The risk sits with older or industry-specific programs. So we test your line-of-business software on Windows 11 before rollout, rather than finding a problem after your team is already switched over.
How long does a business migration take?
It depends on fleet size and how many PCs need replacing. A small office of compatible machines can move in days. Larger, mixed fleets with hardware orders may span a few weeks in planned waves. Building a clear inventory up front makes the timeline predictable.
What happens to my old computers?
We wipe them securely to protect your data, then recycle them responsibly. Barlop has long focused on environmentally sound handling of retired equipment, so old machines do not become a data risk or a landfill problem.
Do I have to replace all my computers at once?
No, and most businesses should not. A blended plan upgrades the PCs that qualify, replaces the ones that cannot make the jump, and uses a short ESU bridge for the few workloads that need more time. It keeps cash flow steady and security intact.
Does Windows 11 really improve security?
The hardware-backed features do raise the floor, and Microsoft reports a notable drop in malware on Windows 11 versus older setups. Still, no operating system is a full defense. Pair the upgrade with backups, monitoring, and staff training for real protection.
Can Barlop handle the whole migration for us?
Yes. From the first audit to the final training session, our Doral-based team manages the entire project. You stay focused on running the business while we handle the desktops, the testing, and the support that follows.
