Windows 10 to Windows 11: What Your Dental Practice Needs to Know

Windows 10 to Windows 11: What Your Dental Practice Needs to Know

Windows 10 reached end of support on October 14, 2025, and no longer receives free security updates. If you're still using it, your options are: upgrade to Windows 11 (if your hardware qualifies), enroll in paid Extended Security Updates (ESU) as a temporary bridge, or replace machines that can't support Windows 11. Consumer ESU coverage ends October 13, 2026; business ESU can extend coverage through October 2027 at a higher cost.

Here's something most articles about this topic get wrong: they assume everyone reading is in the exact same spot. Still on Windows 10, hasn't done anything yet, mildly panicking.

That's not most practices. Some upgraded a batch of machines last spring and haven't touched it since. Some are paying for ESU and not entirely sure what that's buying you. Some have a front desk running Windows 11 and two operatory computers that are, honestly, nobody's quite sure. All of that is normal. So, let's find out where you stand and go from there.

Which One Sounds Like You?

"We haven't done anything yet." Your machines are still running Windows 10, and beyond seeing a notification here and there, nothing's changed. You're not alone. This describes a lot of practices, and it's a completely fixable starting point, if you don't wait too much longer to move.

"We're on ESU." You (or whoever manages your IT) enrolled in Extended Security Updates at some point, and you're currently covered. That's a reasonable short-term move, but ESU has an expiration date of its own, and it's worth knowing exactly when yours runs out.

"We already upgraded." Some or all your machines are on Windows 11. Good, but "we upgraded" and "we upgraded everything, correctly, and validated it against our imaging software" aren't always the same sentence, so it's worth a second look.

"Honestly, it's a mix." This is the most common answer, and the trickiest to manage, because it means you have machines in two or three of the categories above simultaneously… which makes it easy for one or two stragglers to slip through unnoticed.

Wherever you landed, here's the shared background everyone needs, and then a path forward for each one.

Quick Recap of the Retirement of Windows 10

Windows 10 reached its official end of support on October 14, 2025. That didn't turn any computers off, it just means Microsoft stopped issuing free, routine security patches for it. Extended Security Updates, or ESU, is the paid bridge program that keeps critical security patches coming a while longer, but it comes in two different flavors that aren't interchangeable:

  • Consumer ESU: Built for personal Home-edition devices, runs out October 13, 2026.
  • Business ESU: Applies to domain-joined or IT-managed machines (most practice computers, even in a single-location office), with license extensions over a 1-year or 2-year span.

That's the backdrop. Now, your path.

Windows 10 isn’t the only clock running. If your practice management software or imaging is stored on an on-premise server, Windows Server 2016 has its own end-of-support deadline – worth planning alongside this one rather than as a separate project later.

If You Haven't Started Yet

The most useful thing you can do this month is an inventory: every Windows 10 machine, what it's used for, and whether it's domain-joined. From there, each machine sorts into one of three lanes: (1) upgrade to Windows 11, (2) buy a short ESU bridge while you plan, or (3) replace it outright if the hardware can't support Windows 11 at all (a lot of otherwise-fine machines fall short on requirements like TPM 2.0). The sooner this starts, the more choice you have over timing and cost. Waiting until the fall means competing with every other practice trying to do the same thing at once. Or dealing with rising cost of hardware if a computer replacement is needed.

If You're on Windows 10 ESU

First, confirm which program you're enrolled in and when it expires. This is important because consumer and business ESU have different expiration dates, different eligibility rules, and neither one renews itself indefinitely. ESU was designed as a bridge, not a resting place, so the real question isn't "are we covered right now," it's "what are we doing with the extra time we bought." If you don’t have a plan yet, that's your starting point before the bridge runs out and you're back to square one, just later and more rushed.

If You're a Mixed Fleet (Most Practices)

This is the version that benefits most from an actual list rather than a mental tally. It's easy to be confident about the computers you think about often (usually front desk) and much less certain about the ones tucked in a back room or an operatory that's rarely the center of attention. A short inventory turns "it's a mix" into a specific, finite list of what's left to handle.

If You've Already Upgraded to Windows 11

Worth confirming a few things rather than assuming: did every relevant computer get upgraded, or just the visible ones… front desk and doctor, while an operatory computer or two got missed? Has your imaging, X-ray, and practice management software been specifically validated on Windows 11, not just installed and assumed to work? These gaps tend to surface at the worst possible moment and it’s something you want to stay ahead of before it costs your practice unnecessary downtime.

Your 3-Step Plan, Wherever You're Starting From

  1. Get a real inventory: Every machine, its status, and whether it's domain-joined.
  2. Sort what's left, computer by computer: Upgrade, ESU-bridge, or replace.
  3. Schedule upgrades or installations: Plan around your patients, staggering changes by role so nothing causes unnecessary downtime.

FAQs about Windows 10 to Windows 11

Here are some common questions related to updating from Windows 10 to Windows 11. Click the question to see the answer below.

Do I need to upgrade from Windows 10?

Yes. Windows 10 stopped receiving free security updates on October 14, 2025, so unpatched vulnerabilities accumulate the longer a machine stays on it. ESU can delay the decision, but Microsoft built it as a temporary bridge, not a long-term option.

It depends on whether the machine is enrolled in Extended Security Updates. Without ESU, a Windows 10 device no longer receives security patches at all, and risk increases the longer that goes on. With ESU, critical security patches continue, but new features and general technical support do not.

Extended Security Updates (ESU) is a paid Microsoft program that continues critical security patches after standard support ends. Consumer ESU is for personal devices. Business ESU applies to most domain-joined practice computers.

Yes, if the hardware meets Windows 11's requirements, including TPM 2.0 support. Many computers five years or older fall short of these requirements and need to be replaced rather than upgraded.

The computer keeps working, but stops receiving security patches entirely. Newly discovered vulnerabilities never get fixed on that machine, which raises the risk of malware or ransomware over time… a meaningful concern for any system that touches patient data. Therefore, your practice would fall short on HIPAA compliance, as well as possible denied claims from your cyber liability insurer should a breach occur on your network.
