Windows 10 end of support: what small businesses should do now
Windows 10 reached end of support on October 14, 2025. Microsoft no longer issues security updates for it. For a business that runs payroll, QuickBooks, or client files, that is a risk worth closing. Here is what to do, in plain English.
What end of support actually means.
No more security updates. No more bug fixes. When a new vulnerability is found in Windows 10, it will not be patched.
Your PC will keep working. The risk is that it becomes easier to compromise over time. For a business, that risk lands on your data.
Microsoft offers a paid program called Extended Security Updates, but the free ride is over. For businesses, the paid protection costs about $61 per device per year and buys time, not a permanent fix.
What you do not need to do.
You do not need to buy a full new fleet this week. You do not need to panic.
You do need a plan. Most Windows 10 PCs from the last few years can run Windows 11. The ones that cannot are usually five years old or older, and they were due for replacement anyway.
The businesses that handle this well treat it as a project with a checklist, not a fire drill.
The upgrade, done carefully.
The right way: check that your business software works on Windows 11 first. QuickBooks versions, industry apps, and printers all need checking.
Then move data and settings, and install. We do this for Suffolk County businesses every week.
A careful upgrade keeps your files, your QuickBooks company file, and your email settings intact. The move should be invisible to your team by Monday morning.
If your PCs are too old.
Some older PCs cannot run Windows 11. If that is the case, the honest answer is replacement. We will tell you when a PC is worth upgrading and when it is not.
We sell business PCs selected for the work they do, and we migrate your data and settings. Old hardware is also slow hardware, and slow hardware costs you time every single day.
What the extended security option is worth.
If you absolutely cannot move off Windows 10 yet, Microsoft's paid updates are a bridge, not a destination. They run through October 2026 for the first year, with more years available at a cost.
The bridge is useful for one situation: a line-of-business application that does not work on Windows 11 yet. If that is your situation, plan the exit now, because the bridge ends.
For everyone else, the math is simple. Paying for extended updates on old PCs costs more than upgrading to machines that are supported.
The bottom line.
Windows 10 still runs. The risk grows with every month it runs unpatched. The fix is a plan, not a panic.
Check your software, check your PCs, upgrade what makes sense, and replace what does not. We do this for Suffolk County businesses every week and we can do it for yours.

Why the risk grows every month.
When a security update stops, the vulnerabilities found after that date stay open. Researchers keep finding new ones in Windows 10, and none of them get fixed.
For a business, an unpatched PC is a door. Ransomware and data theft start at doors like that.
This is not a scare story. It is how the update cycle works. Every operating system eventually reaches this point.
What a typical upgrade project looks like.
Step one: inventory the PCs and the software. Step two: check compatibility with Windows 11. Step three: plan the order so the office never stops working.
Step four: upgrade in batches, moving data and settings. Step five: verify everything works, including QuickBooks, printers, and shared folders.
Most small businesses complete this in a week or two of scheduled work. We quote the whole project before it starts.
QuickBooks and Windows 11.
QuickBooks is the software our clients ask about most. Most current versions run fine on Windows 11. Older versions may need an update first.
We check your exact QuickBooks version before any upgrade. If it needs an update, that happens before the operating system changes.
The same rule applies to industry software, scanners, and anything else your office depends on. Check first, upgrade second.
What to do with the old PCs.
PCs that cannot run Windows 11 should be replaced, not forced. We help you recycle responsibly and wipe data properly before anything leaves your office.
A wiped drive matters. Old business computers carry client data, QuickBooks files, and email. Data destruction is part of the replacement project.
We offer secure hard drive wiping and certified destruction for Long Island businesses.
The cost of waiting.
Every month on unpatched Windows 10 raises the chance that a known vulnerability becomes your problem.
The cost of waiting is hard to see until it arrives. When it does, it arrives as downtime, recovery work, and possibly lost data.
A planned upgrade has a known price. An emergency recovery does not.
A simple way to check your own PCs.
Open Settings, go to System, and look at the PC name and specifications. The processor generation and RAM tell you most of what you need to know.
PCs with an 8th generation Intel processor or newer generally support Windows 11. Older ones usually do not.
That is a rough check, not a guarantee. We run the official compatibility check as part of any assessment.
Why we check software before hardware.
The upgrade fails most often because of software, not hardware. A printer driver, an old QuickBooks version, or industry software can stop the whole project.
We inventory software first, verify compatibility, then upgrade machines. That order is why our upgrades finish on schedule.
It is more work up front and far less drama on the day.
FAQ
Questions business owners ask.
Is Windows 10 still safe to use?
It still works, but it no longer receives security updates. The longer it runs unpatched, the more risk builds up.
How much does upgrading to Windows 11 cost?
It depends on how many PCs and what software needs checking. We quote before work begins.
Will my QuickBooks work on Windows 11?
Most current versions do. We check your exact version before upgrading.
Do I need new computers for Windows 11?
Not always. Many Windows 10 PCs meet the requirements. We check before recommending purchases.
What is Microsoft's Extended Security Updates program?
A paid program that keeps Windows 10 patched for a limited time. It is a bridge, not a permanent fix, and it costs about $61 per device per year for businesses.
