Outdated Technology Your Business Should Replace (2026 Edition)

Most "outdated tech" articles still talk about Internet Explorer and Adobe Flash. Those conversations happened four years ago. If your Treasure Valley or East Idaho business is still running either of those, we need to talk — but that's not why we wrote this.

This post is about the technology that Idaho businesses are actually still running right now that is either already past end of life or expiring within the next twelve months. These aren't hypothetical risks. They're open doors on your network with no patches coming.

Why End-of-Life Technology Is a Security Problem

When a software vendor ends support for a product, they stop releasing security patches. Researchers keep finding vulnerabilities in that software — they just stop getting fixed. Attackers know exactly which versions are unsupported, and they actively target them because they're easy. Running an EOL product isn't just inefficient, it's a liability.

For manufacturers and engineering firms in Idaho who carry cyber insurance, it can also be a coverage problem. Many policies now require that systems be on supported software. An EOL device involved in a breach could give your insurer grounds to deny the claim.

What to Remove or Replace Now

Windows 10 — EOL October 14, 2025

Windows 10 is the one we're hearing about most from businesses across the Treasure Valley. It feels fine. It still runs. But Microsoft stopped patching it last October, which means every vulnerability discovered since then stays open permanently. If you still have Windows 10 machines, you need a plan. We've covered your options in detail — [read the full guide here →].

SQL Server 2016 — Extended Support Ends July 14, 2026

This one is urgent. SQL Server 2016's extended support window closes in two weeks. If your business runs any applications on SQL Server 2016 — manufacturing ERP systems, line-of-business applications, customer databases — you are out of time to plan and into execution. After July 14, no more security patches. Microsoft does offer Extended Security Updates as a paid bridge while you migrate to a newer version, but that conversation needs to happen now, not in August.

Windows Server 2016 — Extended Support Ends January 2027

You have time, but not as much as you think. Windows Server 2016 reaches end of extended support in January 2027, which sounds like a comfortable runway until you consider how long server migrations actually take — especially in environments where servers are running business-critical applications. Start your assessment now. Migrating a server at the last minute, under pressure, is where things go wrong.

Exchange Server 2016 and 2019 — EOL October 14, 2025

If your business is still running Exchange on-premises, both the 2016 and 2019 versions reached end of life in October 2025. Microsoft's clear direction here has been toward Exchange Online and Microsoft 365. If you haven't already made that move, this is overdue. On-premises Exchange is one of the most actively targeted entry points in the threat landscape — a legacy mail server with no patches is not somewhere you want to be.

Office 2016 — EOL October 14, 2025

Office 2016 quietly hit its end of life date alongside Exchange and Windows 10. If you have staff still using Office 2016 — standalone installs, not Microsoft 365 — those applications are no longer receiving security updates. Beyond the security concern, Office 2016 can't access Copilot features and is increasingly incompatible with current file formats and collaboration tools. If your team is on Microsoft 365, this likely isn't an issue. If not, it's worth an audit.

Traditional VPN Solutions

This one doesn't have a single end-of-life date, but it deserves a spot on this list because traditional VPNs are quietly becoming a liability for businesses with remote or hybrid teams.

The problem is how VPNs were built: they create a tunnel into your network and grant the connected device broad access, trusting it simply because it authenticated. That model made sense when everyone worked from a single office and all your applications lived on local servers. It doesn't hold up when your team is working from home in Nampa, a job site in Idaho Falls, and a hotel in Salt Lake City — all accessing cloud applications that never touch your internal network.

Legacy VPN appliances are also a consistent target for attackers. Several major ransomware campaigns in recent years have started with an exploited VPN vulnerability.

The modern replacement is SASE — Secure Access Service Edge. Rather than routing traffic through a central point, SASE enforces security at the edge, wherever the user and device are. Access is granted based on identity, device health, and context — not just whether someone authenticated to the VPN. For businesses with multiple locations, remote workers, or cloud-first infrastructure, it's a fundamentally better fit.

How to Know What You're Running

Most business owners don't have a clear picture of every software version across every device in their environment — and that's not a criticism, it's just reality. A device audit gives you that picture: what's running, what's EOL, what's due for replacement, and in what order to tackle it.

TotalCare IT does this for businesses across Eastern and Western Idaho, with offices in both Boise and Idaho Falls. If you're not sure where you stand, that's exactly where we start.
