Your Windows 11 Migration Plan for Pueblo and Colorado Springs SMBs Still on Windows 10

Windows 10 reached end of support on October 14, 2025, roughly nine months ago. If you are a Pueblo or Colorado Springs business owner still running Windows 10 on most of your desktops and laptops, you are not alone. Plenty of SMBs across Southern Colorado put off the move because the upgrade math looked ugly, the budget was already committed somewhere else, or the IT person who used to handle this left the company. None of those are great reasons, but they are real ones.

Here is what changed when support ended. Microsoft stopped shipping security updates through the normal Windows Update channel for any device not enrolled in Extended Security Updates. Microsoft also stopped fixing bugs, stopped releasing feature updates, and stopped offering technical assistance. The machine still boots. The software still runs. But every new vulnerability discovered after October 2025 stays unpatched on a non-ESU Windows 10 device.

That is the part that ought to make you nervous. Not the user experience. Not the missing features. The unpatched-vulnerability part. If you handle client data, run a job-cost system, store cardholder information, or carry cyber insurance, you have a problem that is getting more expensive every month you ignore it.

The ESU math, and why it gets worse fast

Microsoft did give businesses a paid bridge. The Extended Security Updates program lets a commercial Windows 10 device keep getting critical and important security patches for up to three years past end of support. Here is the pricing as it stands right now.

• Year 1 (Oct 2025 to Oct 2026): $61 per device
• Year 2 (Oct 2026 to Oct 2027): $122 per device
• Year 3 (Oct 2027 to Oct 2028): $244 per device

It doubles every year. And it is cumulative. If you skipped Year 1 and try to enroll a device for Year 2 in November, you owe both years. $61 plus $122. So a business that comes to us in late 2026 with twenty Windows 10 machines that never got enrolled is staring at $3,660 in pure ESU fees just to keep those boxes patched into 2027. That money buys you exactly zero new functionality. It buys you patches.

There is a cloud-managed discount of roughly 25 percent for organizations using Microsoft Intune or Windows Autopatch, but that requires the management infrastructure to already be in place. In our experience, plenty of small construction firms around Pueblo are not running Intune yet.

$61 per device this year. $122 next year. $244 the year after. ESU pricing doubles annually and you cannot skip a year without paying retroactively.

Which of your machines can actually run Windows 11

Before you budget anything, you need to know which of your existing devices qualify for an in-place upgrade and which need replacement. The Windows 11 requirements are stricter than people remember from the Windows 10 days.

Minimum specs:

• 64-bit processor, 1 GHz or faster, 2+ cores
• 4 GB RAM (8 GB is the realistic floor for business use)
• 64 GB storage
• TPM 2.0 chip
• UEFI firmware with Secure Boot capability
• DirectX 12 compatible graphics
• 720p display larger than 9 inches

The TPM 2.0 requirement is what kills most older devices. A perfectly functional 2018 Dell OptiPlex tower might have a TPM 1.2 chip, or no TPM at all if it was a budget build. Same story with a lot of the i5 laptops procured during the WFH scramble in 2020 from whoever had stock. The PC Health Check app from Microsoft will tell you in under a minute per machine.

Our rough rule for SMB clients across Pueblo and Colorado Springs: machines purchased new in 2021 or later usually upgrade in place. Machines from 2019 or earlier almost always need replacement. The 2020 cohort is mixed and you have to check each one. Anything with a 7th-gen Intel chip or older is a definite replace.

A realistic 90-day migration framework

We have run this same playbook with several Southern Colorado clients over the past year. The structure works for any business between 5 and 50 endpoints. One caveat on timing, though. If you are reading this in the summer of 2026, ninety days puts you right at the October Year 1 ESU cutoff, so treat this as a start-now plan, not a start-next-quarter one.

Days 1 to 15: Inventory and assessment. Run PC Health Check on every machine. Build a spreadsheet with device, age, owner, upgrade eligibility, and current Windows 10 build. Identify the line-of-business apps each user depends on and check the vendor's Windows 11 compatibility statement. Estimating software, plan-takeoff tools, and the older job-cost systems are where you find the surprises.

Days 16 to 30: Procurement and pilot. Order replacement hardware for the machines that fail Health Check. For everything else, pick 2 or 3 users to pilot the in-place upgrade. Choose users who can tolerate a short disruption and who exercise the critical apps. Document any driver issues, printer issues, or login flow changes.

Days 31 to 60: Rolling deployment. Upgrade or replace the rest of the fleet in waves of 4 to 6 machines per week. Schedule each wave for a Friday afternoon and Saturday morning so the user has the weekend to settle in. Pre-stage user profiles, OneDrive sync, and any local app installs so Monday morning is just login and go.

Days 61 to 90: Cleanup, training, and Windows 10 retirement. Wipe and dispose of the replaced hardware properly. Run a final pass on any stragglers. Pull a 30-minute team session on what is different in Windows 11 (the centered taskbar, the new Settings app, Snap layouts). And critically, deprovision any leftover Windows 10 machines that are not on ESU. Either get them enrolled or shut them down. A non-ESU Windows 10 device sitting in your office connected to your network is a liability and your cyber insurance carrier will treat it as one.

The Southern Colorado angle

A few things specific to running this migration in Pueblo and Colorado Springs are worth calling out.

Construction and trades clients have mixed environments. The office has a handful of desktops, but the foremen carry rugged laptops or tablets in the trucks. Those mobile devices are usually older because nobody wants to put a brand-new ThinkPad in a F-250 console. They are also the most likely to be missing TPM 2.0. Plan for the truck fleet separately and budget for ruggedized Windows 11 hardware where it matters.

Internet bandwidth at outlying sites still matters. If your headquarters is in Pueblo and you have a yard in Pueblo West or a job trailer in Fountain, the upgrade ISO is 4 to 6 GB per machine. Doing 30 of those on a 100 Mbps connection adds real time. We stage upgrades on a local USB or on a cached deployment server when bandwidth is the bottleneck.

Your insurance carrier already knows the Windows 10 end-of-life date. Cyber insurers have been tightening around unsupported operating systems, and it is increasingly common to see explicit unsupported-OS exclusions show up on renewal questionnaires. If you are renewing in the second half of 2026 with Windows 10 machines that are not on ESU, expect either a higher premium, a coverage carve-out for those machines, or a non-renewal. Read the renewal form carefully before you sign it.

What to do this week

If you are reading this and you still have Windows 10 machines in production, three concrete steps move you forward.

First, run PC Health Check on every business device. It is free, takes a minute per machine, and gives you the data you need to budget. Second, decide on the ESU question. If you have to keep some Windows 10 devices alive through 2027 (because a critical app vendor has not released a Windows 11 compatible version), get them enrolled now while you are still in the Year 1 window. Third, pick a target completion date and be honest about the calendar. If you start a ninety-day migration now, in mid-July, you land right around the end of Year 1 ESU pricing in October 2026. There is almost no slack left in that window, and every week you wait pushes you closer to the Year 2 doubling penalty. So treat ESU enrollment as a safety net for the few machines that truly cannot move yet, not as a reason to slow the migration down.

If you want help with the inventory, the procurement, or the rolling deployment, that is what we do. GTZ Integrations runs managed IT services for Pueblo and Colorado Springs businesses across construction, manufacturing, and professional services. We handle the migration as a flat-fee project or roll it into a managed services agreement. Either way, the goal is the same: every machine on a supported OS by your target date, no surprises, no last-minute scramble.
