Windows 10 End of Support: What Your Business Should Do in 2026
Windows 10 has reached the end of Microsoft's free support. If your business is still running it, this is not a message to file away for later — every day on an unsupported operating system is a day without new security patches, and attackers actively target exactly these machines. Here's what it means and the three real paths forward.
What "end of support" actually means for you
Your Windows 10 PCs still turn on and work. That's what makes this risk easy to ignore. But Microsoft has stopped shipping free security updates, which means:
- New vulnerabilities won't be patched. Every flaw discovered from here on stays open on your machines.
- Compliance breaks. HIPAA, PCI, CMMC, and cyber-insurance requirements all expect supported, patched systems. An unsupported OS can fail an audit or void a claim.
- Software and hardware support fades. Vendors increasingly drop testing and support for Windows 10.
In short: it works until the day it very much doesn't, and that day tends to be expensive.
Your three options
1. Upgrade eligible PCs to Windows 11 (best for most)
Many business PCs from the last few years can upgrade to Windows 11 for free. The catch is the hardware requirements — chiefly TPM 2.0 and a supported processor — so some older machines won't qualify. The right first step is an inventory that sorts your fleet into "upgrade now" and "needs replacement."
2. Buy Extended Security Updates (ESU) as a bridge
Microsoft offers paid Extended Security Updates for Windows 10, available to businesses for up to three additional years. ESU is a bridge, not a destination — the price increases each year by design, to push you toward upgrading. It makes sense for machines you can't replace immediately or specialized systems tied to older software, but it shouldn't become your long-term plan.
3. Replace aging hardware
PCs that can't run Windows 11 and are already several years old are often best replaced. The upside: newer machines are faster, more secure by default, and come with Windows 11 ready to go. Staging the refresh in waves keeps the cap-ex predictable rather than hitting all at once.
The smart move: a staged plan, not a scramble
The worst approach is doing nothing until something breaks or an auditor asks. The best approach is a simple plan: inventory every device, upgrade the ones that qualify, put short-term ESU on anything that genuinely needs more time, and budget the hardware replacements in manageable waves.
