Windows 10 ESU Ends Oct 13: A Burnaby AI-Ready Checklist

If your office still has a few Windows 10 machines humming along, October 13, 2026 is a date worth circling. It's the day Year One of Microsoft's paid Extended Security Updates (ESU) program for businesses ends, according to Microsoft's Lifecycle FAQ on Extended Security Updates. After that, a Windows 10 business PC only keeps getting security fixes if someone has paid for Year Two.

If your Burnaby or New Westminster office bought ESU last fall as a stopgap, this checklist is for you. It's also for anyone planning to run AI tools on their office PCs next year, because the upgrade decision and the AI decision now overlap more than they used to.

What actually changes on October 13

Here's the timeline, straight from Microsoft's documentation (checked September 2026):

Windows 10 reached end of support on October 14, 2025. Microsoft's ESU program page for Windows 10 says that since then, unenrolled PCs get no technical support, no feature updates and no quality updates, including security fixes. The PCs still turn on. They just stop getting patched.

The commercial ESU schedule in the Lifecycle FAQ runs in yearly blocks: Year One ends October 13, 2026, Year Two ends October 12, 2027, and Year Three ends October 10, 2028. The same FAQ says the qualifying editions are Enterprise, Education, and Pro in commercial use.

One thing that trips people up: the consumer program is on a different track. As of September 2026, Microsoft's consumer ESU page says home users get updates through October 12, 2027. So if you read a headline saying "extended updates end October 13", check which program your PCs are actually enrolled in. For a business using Pro licences, it's the commercial one.

What staying on Windows 10 costs

According to Microsoft's ESU page, as of September 2026, business ESU is sold through Microsoft Volume Licensing at $61 USD per device for Year One, and "the price doubles every consecutive year, for a maximum of three years." It's sold by the year only, with a minimum of one licence. And it's cumulative: if you join in Year Two, you pay for Year One too.

Illustrative math, not a quote: a 10 PC office that skipped Year One and wants coverage now would pay for Year One ($61) plus Year Two (double, so $122) on each machine. That's roughly $1,830 USD before tax and reseller margins. Year Three would double again. Put that next to what 10 replacement PCs cost you and the answer is often obvious.

There's one exception worth knowing. Microsoft says ESU comes at no additional cost for Windows 10 virtual machines in Windows 365, Azure Virtual Desktop and several other Azure services, and that Windows 10 devices connecting to Windows 365 Cloud PCs are entitled to ESU for up to three years with an active subscription.

The upgrade checklist

Work through this with whoever handles your IT.

• Inventory every Windows PC. Include the front desk machine, the one running the label printer, and the laptop in the owner's car. Note the Windows edition and version for each.
• Confirm ESU status on anything staying on Windows 10. Microsoft requires Windows 10, version 22H2 for ESU. Find out whether you bought Year One and whether Year Two is needed before October 13.
• Check Windows 11 eligibility. Microsoft's Windows 11 requirements (updated July 2026) list a compatible 64 bit processor with two or more cores, 4 GB of RAM, 64 GB of storage, UEFI with Secure Boot capability, and TPM 2.0.
• Back up before you touch anything. The Canadian Centre for Cyber Security's Baseline Cyber Security Controls for Small and Medium Organizations calls for backing up essential business information, encrypting backups, and keeping long term backups offline.
• Test your line of business apps. Accounting software, POS drivers, scanners and old industry tools are where upgrades break. Try one machine first.
• Decide replace, upgrade or retire for each device. Eligible PCs can upgrade in place. Ineligible ones either get ESU, move to a cloud PC, or get replaced.
• Buy replacements with the next four years in mind. That's where AI comes in, below.
• Wipe and recycle old drives properly. Customer data on a forgotten laptop is still customer data.

Why this matters for security and privacy in BC

This isn't just Microsoft telling you to buy things. The Cyber Centre's baseline controls, written for organizations with fewer than 499 employees, tell small businesses to consider "replacing software and hardware that no longer receive updates because the vendor ended support (i.e. products past their end of life)."

BC's own privacy law points the same way. Section 34 of the Personal Information Protection Act says an organization "must protect personal information in its custody or under its control by making reasonable security arrangements." We're not lawyers, and nothing here is legal advice. Still, it's hard to argue an unpatched PC holding client files is a reasonable arrangement.

Where AI fits into the decision

If you're buying new PCs anyway, think about the AI work you'll want them to do. Microsoft's Copilot+ PCs developer guide (updated August 2026) describes Copilot+ PCs as Windows 11 hardware with a neural processing unit (NPU) that can run more than 40 trillion operations per second (TOPS), and says many of the new Windows AI features require that 40+ TOPS NPU. The guide lists machines built on Qualcomm Snapdragon X, AMD Ryzen AI 300 series and Intel Core Ultra 200V series chips.

Be honest about what you need, though. Most of the AI a small business uses day to day, like chat assistants, AI receptionists, email drafting and bookkeeping automation, runs in the cloud. It works in a browser on any supported Windows 11 PC. An NPU mainly matters for on device features and for staff who'll run local AI models. For a two person office that answers email and books appointments, a standard Windows 11 machine is fine.

What does matter for AI is the security baseline. An AI assistant that reads your inbox or your customer records is only as safe as the machine it runs on. Patch first, automate second.

Where this doesn't apply

Some honest limits:

• Specialized equipment. Lab instruments, CNC machines and medical devices often run Windows 10 tied to vendor software. Upgrading them yourself can void support. Talk to the equipment vendor, and isolate those machines on the network if you can't update them.
• LTSC editions. Microsoft's lifecycle page for Windows 10 Home and Pro notes existing Long Term Servicing Channel releases keep getting updates on their own schedules. If you run LTSC, this deadline may not be yours.
• ESU isn't support. Microsoft says ESU covers critical and important security updates only. No new features, no general tech support.
• Buying AI hardware too early. If you don't have a specific on device AI use case yet, don't pay a premium for one. Cloud AI tools don't need it, and you can buy it once you have a real need.
• Very small setups. A sole proprietor with one Home edition laptop may fall under the consumer program instead, with its different October 2027 date.

The short version

Find out which PCs are on Windows 10, whether they're covered past October 13, and whether each one should be upgraded, covered or replaced. Back up first. Buy new hardware with your actual AI plans in mind, not the marketing.
