Windows 10 Support Is Over and the Cheap Way Out Expires in October

Microsoft stopped supporting Windows 10 on October 14, 2025. A lot of businesses are still running it, still getting work done, and still assuming nothing bad has happened because nothing bad has happened yet.

Something did happen. You just cannot see it from the desk.

There is a deadline coming that you can see, though, and it has a price tag on it. Microsoft sells a paid extension called Extended Security Updates. Year one of that program runs through October 13, 2026. On October 14 the price per machine doubles. If you are running Windows 10 in your business, you have until October 13 to decide what you are doing, and every path except one gets more expensive after that.

What actually changed when support ended

Your computers did not stop working on October 14, 2025. They still boot, Outlook still opens, the printer still jams the same way it always did. That is exactly what makes this dangerous.

What stopped was security patching. Microsoft finds flaws in Windows constantly, and every month it ships fixes for them. Those fixes are the only reason a decades old operating system stays usable on the open internet. When the patches stop, the flaws keep getting found and published, and nothing closes them.

An unsupported operating system does not fail. It accumulates. Every month that passes, the list of known, published, unpatched ways into that machine gets longer, and the tools to exploit them get easier to buy. A Windows 10 machine today is meaningfully more exposed than it was a year ago, and it will be meaningfully worse a year from now, and at no point will it warn you.

The paid extension, and what it really costs

Microsoft did leave a door open. Extended Security Updates give you security patches only, for a fee, per device, for up to three years.

For businesses the pricing is deliberately punishing. Year one is sixty one dollars per device and runs to October 13, 2026. Year two is one hundred twenty two dollars per device. Year three is two hundred forty four. It doubles every year on purpose, because this is not a support plan, it is a meter running while you get your act together.

It is also cumulative. If you skip a year and try to buy in later, you pay for the years you missed too. Ride it all the way to the end in 2028 and you have spent four hundred twenty seven dollars per machine to keep a dying operating system breathing, and at the end of it you still have to buy new computers.

Read what that fee does not buy, because this is where people get hurt. It covers security patches. It does not cover general bug fixes. It does not cover driver or firmware updates through Windows Update. It does not include Microsoft technical support. It does nothing for third party software that decides to stop supporting Windows 10 on its own schedule, and that is already happening across the industry.

You are paying an escalating fee for the bare minimum, and the bare minimum keeps shrinking.

Why working fine is the wrong test

The most common reason a business is still on Windows 10 is that nobody has complained. The machines work. The staff are used to them. There is no line item on the P and L labeled unsupported operating system.

Here is where that logic breaks.

If you carry cyber insurance, look at your renewal questionnaire. Carriers have gotten specific about supported software, and answering that question casually is not the same as answering it accurately. A claim is a bad time to discover the difference.

If you handle protected health information, and plenty of dental and medical offices around Clarksville do, running unsupported software is not a technicality. It is a documented finding waiting to be written down.

And Clarksville sits next to Fort Campbell. If any part of your revenue touches defense work, the compliance frameworks in that world do not negotiate about unsupported operating systems. There is no version of that conversation where the answer is that the computers seemed to be working.

None of that shows up as a problem until the exact moment it matters most.

The part nobody warns you about, some machines cannot upgrade

Here is where this stops being a software decision and becomes a budget decision.

Windows 11 has hardware requirements that Windows 10 never had. A TPM 2.0 security chip. A processor from Microsoft’s supported list. UEFI firmware with Secure Boot. Machines built before roughly 2018 frequently fail one of those, and a machine that fails cannot be upgraded no matter how well it runs or how much memory you throw at it.

So when you actually inventory a business that has been on Windows 10 for years, the result is almost never all upgradeable or all replace. It is a split. Some machines take Windows 11 with nothing but time. Some need a setting flipped in firmware that was shipped turned off. And some are simply done, and no amount of wishing changes it.

You cannot budget for this until you know which pile each machine lands in. Most businesses have never counted.

What to actually do

Count first. Every Windows machine, what it runs now, and whether it can take Windows 11. This is not a guess and it is not a walk around the office. It is a real inventory, and it is the only thing that turns this from a vague worry into a number you can plan against.

Then split the list. The machines that upgrade cleanly get scheduled and upgraded, and that work is mostly free. The machines that cannot get a replacement date and a cost, and they get spread across quarters instead of landing all at once. That is the entire trick to making this affordable. The businesses that get hurt are the ones that do nothing until something forces them, and then have to buy everything in the same month.

Use the paid extension only where it buys you something specific. There are legitimate reasons a machine has to stay on Windows 10 for a while, usually a piece of industry software that has not caught up yet. Paying for that on purpose, for a handful of machines, with a date on the calendar for when it ends, is a real decision. Paying it across the whole office because nobody made a plan is just a subscription to your own procrastination, and it doubles every year.

Where we come in

We do this for businesses across Clarksville, Nashville, and southern Kentucky, and the first step is always the same. We count what you have, tell you which machines upgrade for free, which ones need replacing, and what the actual dollar figure looks like spread across the next few quarters.

Most of the time that number is smaller than what people have been quietly dreading. Occasionally it is worse, and that is exactly the kind of thing you want to find out in a planning meeting instead of in an incident.

If you are still running Windows 10 anywhere in your business, get the count done before the price doubles in October. Call us at 931-263-8000 and we will give you a straight answer about where you stand.
