Outdated technology costs you in five ways: security holes that no longer get patched, time lost to slow and failing equipment, problems with cyber insurance and compliance, frustrated employees, and surprise replacement bills. The biggest one right now is software that's out of support. Windows 10, Office 2016 and Office 2019 all stopped getting free security updates on October 14, 2025.
What most businesses don't realize is that "it still works" and "it's still safe" stopped being the same thing. A computer running Windows 10 boots up, opens email and prints just like it did last year. It just doesn't get fixes for the security holes attackers find from now on, unless you pay Microsoft for Extended Security Updates.
Key takeaways
When software reaches end of support, Microsoft stops releasing fixes. For Windows 10, Microsoft says devices "will no longer receive security updates after October 14, 2025." The same date ended support for Office 2016 and 2019, Exchange Server 2016 and 2019, and several other products. Every vulnerability discovered after that date stays open on those machines for good.
Attackers know this. Unpatched systems are among the easiest ways into a network, and one unpatched laptop is all it takes. Organizations that can't upgrade yet can buy Microsoft's paid Extended Security Updates program to keep getting critical fixes for a limited time, but that's a bridge, not a plan.
Slow startups, frozen programs and failing hard drives don't show up on an invoice, but they add up. A few minutes lost per person per day across a 30-person team turns into weeks of paid time each year. Old systems also tend to need workarounds that only one person understands, which becomes a real problem when that person is out.
Cyber insurance applications and compliance reviews ask whether your systems are supported and patched. Unsupported operating systems are a hard answer to explain, and they can complicate a claim if something goes wrong. For healthcare, law, accounting and financial firms, running unsupported software can also put you at odds with your regulatory obligations to protect client data.
Nobody does their best work fighting a slow computer. Outdated equipment is a daily frustration for your team, it makes your business look behind to new hires, and it pushes people toward workarounds like using personal devices, which creates security problems of its own.
Hardware fails eventually. If every computer was bought at the same time, they tend to fail around the same time, and you end up replacing a dozen machines in one painful quarter, in a hurry, at whatever price is available that week.
Many can't. Microsoft's minimum requirements for Windows 11 include a compatible 64-bit processor, 4 GB of memory, 64 GB of storage, UEFI with Secure Boot, and a Trusted Platform Module (TPM) version 2.0. Microsoft notes that "with Windows 11, both new and upgraded devices must have TPM 2.0." Many older PCs don't meet those requirements and can't be upgraded, so they need to be replaced.
And when you buy hardware, know what you're paying for. We don't mark up hardware, and it's worth checking how your current provider handles it. See how markups and equipment rentals keep you paying.
Windows 10 still runs, but it stopped receiving free security updates on October 14, 2025. Any new vulnerability stays open unless the device is enrolled in Microsoft's paid Extended Security Updates program. For business computers that handle client data, plan to upgrade or replace them.
Microsoft stops providing security updates, bug fixes and technical support for the product. It keeps working, but it no longer gets fixes for newly discovered problems.
Usually because it lacks a TPM 2.0 chip, Secure Boot support or a processor on Microsoft's supported list. Those are hardware limits, so the fix is a newer computer rather than a software change.
No. Office 2016 and Office 2019 reached end of support on October 14, 2025. Microsoft 365 Apps, which come with Microsoft 365 Business Standard and Premium, update automatically and don't have a fixed end date.
We plan on a roughly five-year cycle for most business computers, adjusted for how hard they're used. Spreading replacements across years keeps budgets predictable and avoids replacing everything at once.
It depends on how many devices you have and how old they are. Planning replacements over several years turns one large, unexpected expense into a predictable yearly budget line. We'll build that plan with you as part of regular strategy meetings.
We get it. Nobody has time to check the version number on every computer. We'll inventory what you have, flag what's out of support and build a replacement plan that fits your budget, with local engineers in Sarasota and same-day on-site help when you need it. Talk to our team.
