Windows 10 ESU 2027: Cost, How to Enroll, How to Check Status and What to Do Next

Start here: what Microsoft's own pages confirm today

Microsoft's consumer Windows 10 ESU page says the program ends on October 12, 2027, and that you can enroll at any time before then; enrolled devices are covered through that date. Consumer enrollment costs nothing if you sync your PC settings, 1,000 Microsoft Rewards points, or a one-time $30 USD (or local equivalent, plus tax). Businesses buy ESU through volume licensing at $61 USD per device for Year One, and the price doubles each year for a maximum of three years.

The search results for this topic are a mess, and that is not your imagination. Older articles still say consumer ESU stops on October 13, 2026. Newer ones say October 12, 2027. Some give a Year Two price for businesses, some give a "late joiner" price, and a few mix up consumer and business rules. This guide does one specific job: it separates what Microsoft's own pages state from what is merely reported, and then helps you decide, enroll, check, and (if needed) leave Windows 10 safely.

We already published two companion pages. For the general story of the extension and the October 2026 date confusion, read Windows 10 ESU Free Extension: What Oct 13, 2026 Means. For Quebec small businesses and the French-language angle, see Fin de support Windows 10 : ESU gratuit 2027 au Québec. This page is different: it is a decision guide with a cost table by scenario, exact steps to check enrollment status, a troubleshooting list for "ESU not showing", and a clear comparison of ESU versus upgrading versus buying a new PC.

Confirmed by Microsoft versus reported elsewhere

We opened Microsoft's pages directly on November 5, 2026 and kept a strict rule: if a number or date is not on a Microsoft page, it is not stated as fact. The table below is the result. Anything in the right-hand column is useful context but you should not budget around it without checking.

That last row matters more than the price. ESU is a safety net for security patches. It is not a license to keep running a slow, aging PC forever, and it does not make Windows 10 supported in the old sense.

The timeline in plain language

Three dates frame every decision on this page.

• October 14, 2025: Windows 10 reached end of support. Microsoft stopped providing free security fixes, feature updates and technical assistance for it. PCs still run.
• Now (November 2026): consumer ESU enrollment is open and, per Microsoft, stays open until the program ends. Business buyers who skipped the first year can still buy, but must cover the first year too.
• October 12, 2027: end of the consumer ESU program. For personal PCs, this is your hard deadline to be on Windows 11, on another supported system, or accept unpatched risk.

One more date worth knowing if you run Microsoft 365 on a Windows 10 PC: Microsoft states its security updates for Microsoft 365 Apps on Windows 10 continue until October 10, 2028. That helps Office, not the operating system underneath it.

Who can use the consumer path, and who must go the business route

The single most common mistake we see is a small-business owner following a consumer guide on a work PC. Microsoft draws the line clearly: the consumer program is for eligible Windows 10 PCs (version 22H2) used for personal purposes and not managed by an organization. Organizations buy ESU through volume licensing, and Microsoft Learn even opens its commercial pages with a banner pointing individuals to the consumer page instead.

The "home-based freelancer" row deserves honesty. Microsoft's consumer page speaks of personal use. If the PC holds client files, is joined to a business tenant, or is managed through Intune, treat it as a business device. Quebec businesses also have Law 25 obligations around personal information; an unpatched machine holding customer data is a harder position to defend than a PC with a few dollars of ESU.

Requirements before you can enroll

Microsoft lists these consumer prerequisites on its ESU page:

• Windows 10 version 22H2, Home, Professional, Pro Education or Workstations edition.
• The latest Windows update installed.
• The Windows 10 ESU Licensing Preparation Package, KB5126256. Windows Update normally delivers it, so for most people this means "run Windows Update until nothing is pending".
• The Microsoft account you sign in with must be an administrator account on that device.

Not on 22H2? Run Windows Update first. Windows 10 22H2 was the final Windows 10 release, so if Update offers nothing, check for a pending restart before assuming something is broken. Our Windows 10 end-of-life migration guide covers the broader business migration planning.

How to enroll a personal PC, step by step

Microsoft says enrollment uses a built-in tool in Settings and that you must sign in with a Microsoft account. Screens change between builds, so the wording below is a guide, not a screenshot.

1. Back up first. Copy documents, photos and browser bookmarks to an external drive or OneDrive. ESU does not replace backups, and any update can go wrong.
2. Update fully. Settings, Update & Security, Windows Update. Install everything offered, restart, and repeat until it says you are up to date.
3. Sign in as an administrator with a Microsoft account. A local-only account cannot complete enrollment, per Microsoft.
4. Look for the ESU enrollment prompt on the Windows Update page and start it.
5. Choose how you pay. The three options are: syncing your PC settings (no additional cost), redeeming 1,000 Microsoft Rewards points, or the one-time $30 USD purchase. Microsoft states one license can cover up to 10 devices.
6. Finish and restart if asked, then verify using the checks in the next section.

Which option should you pick? If your PC is already syncing settings to your Microsoft account (or you are fine switching that on), the free route is the easy one. Syncing means some settings are stored in your Microsoft account, so if privacy is your concern, read what is synced first and consider the Rewards or purchase route instead. Rewards points are only practical if you already have a balance of 1,000. The $30 USD route is the cleanest if you want no ongoing dependency on settings sync. Microsoft states the price in USD or local currency equivalent plus tax, so the Canadian amount at checkout will vary with the exchange rate and taxes. We did not find a CAD figure printed on Microsoft's page, so check the final amount before confirming.

How a business enrolls: volume licensing and activation

For organizations, Microsoft Learn documents a different process. ESU licenses are bought through volume licensing (typically via a Microsoft partner). After purchase, the license shows up as a Multiple Activation Key (MAK) in the Microsoft 365 admin center, and each device needs it installed and activated.

1. Buy the licenses. Minimum purchase is one license. Microsoft says it must be purchased by whole years, with no partial periods.
2. Find the key. In the Microsoft 365 admin center, go to Billing, then Your Products, then the Volume licensing tab, then view contracts and product keys. Your Entra ID account needs the Product Key Reader or VL Administrator role to see it.
3. Prepare each device. Windows 10 22H2 with KB5066791 or later, plus the ESU Licensing Preparation Package KB5072653 installed after it, per Microsoft Learn. You also need administrator rights on the device.
4. Install and activate. In an elevated Command Prompt, run slmgr.vbs /ipk followed by the MAK, then slmgr.vbs /ato followed by the ESU activation ID for the year you bought.
5. Verify. Run slmgr.vbs /dlv and confirm the ESU program name and a license status of Licensed (details in the next section).

Microsoft also documents a phone activation method and proxy activation with the Volume Activation Management Tool for many offline devices. If you manage more than a handful of PCs, that tooling matters; a managed service provider usually handles it. Our cloud backup guide for Canadian businesses is worth reading in parallel, because patch decisions and backup decisions should be made together.

How to check whether your PC is enrolled in ESU

Enrollment is not a feeling, it is a state you can verify. Do this check right after enrolling, again after the next Patch Tuesday, and once more every few months until the program ends. Here is what Microsoft's pages document, with our honest notes on what they do not.

Personal PC: Settings and Order History

• Windows Update page. Microsoft says to go to Settings, Update & Security, Windows Update. An enrolled consumer device should no longer show the enrollment prompt, and Microsoft states that enrolled devices continue to be covered through October 12, 2027 without further action.
• Order History. If you paid the one-time fee, Microsoft says the purchase appears in your Microsoft account order history. Open your account's order history in a browser and look for the ESU line item.
• Update history. After the next monthly security release, open Windows Update, then View update history, and confirm a recent cumulative security update installed successfully.

Microsoft's consumer page does not publish a single diagnostic screen that says "ESU: Active" in exact words, so we do not promise one. The reliable proof is the combination: no pending enrollment prompt, a purchase or sync record on your Microsoft account, and a successful monthly security update after enrollment.

Business PC: license status with slmgr

For commercial ESU, Microsoft Learn gives a precise check. Open Command Prompt as administrator and run:

slmgr.vbs /dlv

The output should show the Name of the corresponding ESU program (Year 1, Year 2 or Year 3) and the License Status as Licensed. Microsoft publishes a separate activation ID for each ESU year, and they are the same across all eligible devices enrolled in that program. If you see no ESU entry, the key was not installed or activation failed, which is the case where the key must be installed with /ipk and activated with /ato again.

ESU not showing or not working: what to try

Most enrollment failures come from a short list of causes. Work through them in order, because each fix is cheap.

1. The PC is not on 22H2. ESU requires Windows 10 version 22H2. Check with winver and update.
2. Updates are pending. Microsoft requires the latest Windows update. A pending restart often hides the prompt. Restart and check again.
3. Missing preparation package. The consumer path requires KB5126256, the business path KB5072653 installed after KB5066791. Check update history for them.
4. Wrong account type. You must use a Microsoft account with administrator rights for the consumer route. A local account or a standard user cannot enroll.
5. The PC is managed by an organization. A PC joined to a work or school account or controlled by device management follows the commercial route, not the consumer prompt, per Microsoft's personal-use wording.
6. Edition not covered. The consumer page lists Home, Professional, Pro Education and Workstations. LTSC and LTSB are excluded from the program.
7. Network or activation problems. Microsoft Learn lists the endpoints that activation needs. Firewalls, DNS filters and strict proxies commonly block them on business networks.
8. Windows 10 Pro in S mode. Microsoft says S mode must be left before moving to Windows 11 Pro; check your edition details if your PC is a school or budget laptop.

If the prompt simply never appears after steps 1 to 4, do not buy a second license and do not download "ESU activators". Fake activators are a known malware route, and our guide to what ransomware is and how it gets in explains why an unpatched system plus a dodgy download is the worst combination. Unofficial scripts that "force" ESU are not endorsed by Microsoft, and we do not recommend them.

Also be careful with search ads and email: scammers use "Windows 10 expires, pay now" messages to sell fake support or steal card numbers. Microsoft's real enrollment happens inside Windows Settings and your own Microsoft account. A caller, popup or email that demands payment or remote access to "activate ESU" is not Microsoft.

What it costs: a table by scenario

Microsoft gives the rules; the totals below are our arithmetic from those rules, in US dollars as Microsoft prices them. Taxes and the exchange rate to Canadian dollars are on top, and your reseller may add its own margin, so treat these as the floor, not a quote.

Two cautions on the business rows. First, Microsoft prints $61 for Year One and states that the price doubles each year and that Year Two buyers must pay Year One too. It does not print $122, $183 or $244 on the pages we opened, so those figures come from arithmetic on its stated rule. Several resellers quote the same numbers, which supports the math, but check your quote. Second, which calendar dates each business year covers is not on the pages we opened, so ask your reseller for the exact coverage window before you pay for a year.

The consumer rows are easy and cheap. If you have a personal PC and can sync settings, there is little reason not to enroll, even if you plan to leave Windows 10 next spring. It buys time on your schedule, not Microsoft's.

ESU cost versus replacing the PC

The question we hear most from owners of five to twenty PCs is: "Is it cheaper to pay for ESU or to buy new?" The honest answer depends on how old the machines are and what you use them for. Here is a way to compare without guessing.

• ESU is a rental, not an asset. At the commercial rates above, one PC costs $183 USD to cover from now to the end of Year Two, and $427 USD across all three years, and then you still own a Windows 10 PC with no support.
• A new business desktop or laptop commonly runs several hundred to over a thousand Canadian dollars depending on spec. Treat that as an illustrative range, not a quote; get real prices from two suppliers.
• A compatible PC may need nothing. If the machine passes the Windows 11 requirements, the upgrade itself is free for eligible Windows 10 Home or Pro, per Microsoft. The real cost is a Saturday and a backup.
• Refurbished is a real option. A business-grade refurbished PC that meets Windows 11 requirements can cost far less than new. Check the warranty and that it supports TPM 2.0 and Secure Boot.

A simple rule: if a PC is under about five years old and passes the Windows 11 check, upgrade it and skip ESU. If it fails the check but still performs well, ESU for one year is a rational bridge. If it fails the check and is also slow, spend the money on a replacement instead of renting patches for it. A slow disk is often the real culprit, and our SSD versus HDD upgrade and repair cost guide helps you decide whether a drive swap is worth it before you write the machine off.

Business details people get wrong

• Minimum purchase: Microsoft states one license is the minimum.
• Whole years only: you cannot buy six months.
• Cumulative pricing: arriving late does not skip the earlier years' cost.
• Cloud PCs: ESU is included at no additional cost for Windows 10 virtual machines in Windows 365, Azure Virtual Desktop and several Azure services, per Microsoft Learn. Windows 10 endpoints that connect to Windows 365 Cloud PCs are also entitled to ESU with an active subscription license.
• Support: ESU is not a support contract. Microsoft only supports activation, installation and regressions of the ESU itself, and organizations need an active support plan for that.
• Management tools: Microsoft points organizations to Windows Autopatch and Intune for upgrading eligible PCs to Windows 11. Research we reviewed mentioned an Intune or Autopatch ESU price of $45 per device in Year One. We could not confirm that number on Microsoft's pages, so we do not rely on it.

What happens if you do not enroll

Microsoft is direct about this: Windows 10 PCs continue to function after support ends. Nothing flips off. What stops, per Microsoft, is technical support, feature updates, and quality updates including security and reliability fixes. Its end-of-support page adds that unsupported PCs can become more exposed to malware and may slow down over time.

In practical terms, here is what changes for a PC that is neither enrolled nor upgraded:

• New Windows vulnerabilities stay open. Each month, Microsoft publishes fixes for newly found flaws. Enrolled PCs get the critical and important ones; unenrolled PCs get nothing. Attackers study those monthly fixes, so the gap widens over time.
• Software vendors follow Microsoft. Over time, browsers, accounting software and drivers drop support for unsupported Windows versions. We cannot give you a date for any specific vendor, so check the vendor's own lifecycle page for software you depend on.
• Cyber insurance and compliance questions arrive. Insurers and auditors often ask whether systems are supported. Our ransomware and cyber insurance coverage guide explains how an unsupported operating system can weaken a claim or raise a premium. Check your own policy wording rather than assuming.
• Quebec businesses carry Law 25 duties. If a PC holds personal information about customers or employees, reasonable security measures are expected. An unpatched machine is hard to defend after an incident.

Does this mean every unpatched PC will be hacked next week? No, and honest advice avoids fear marketing. A PC that is offline, or used only for a single air-gapped task, carries far less risk than a laptop that browses email and banking sites. The point is that risk accumulates monthly, and you control how long you accept it.

What ESU does not give you

Enrolling in ESU does not turn Windows 10 back into a fully supported product. Per Microsoft:

• ESU covers critical and important security updates only. It excludes new features, customer-requested non-security updates and design change requests.
• Microsoft's technical support for ESU is limited to license activation, installation and possible regressions of the ESU itself.
• It does not make old hardware faster, fix a failing drive, or replace antivirus and backups.
• Third-party software compatibility is outside the ESU promise.

Treat ESU as a bridge with a clear end, not a destination. Pair it with a backup you have tested, a modern browser, and the habits in our business password manager guide, because stolen passwords hurt a fully patched PC just as much as an unpatched one.

Decision guide: ESU, upgrade, or new PC

Use this section in order. It takes about ten minutes per PC and saves most owners from paying for the wrong thing.

Step 1: does the PC meet Windows 11's requirements?

Microsoft lists these minimums for Windows 11:

• Processor: 1 GHz or faster with 2 or more cores on a compatible 64-bit processor or SoC.
• Memory: 4 GB of RAM.
• Storage: 64 GB or larger.
• System firmware: UEFI with Secure Boot capability.
• TPM: version 2.0.
• Graphics: DirectX 12 or later with a WDDM 2.0 driver.
• Display: 720p, larger than 9 inches diagonally, 8 bits per color channel.

Microsoft says the PC Health Check app can assess compatibility on a PC that already runs Windows 10, and its end-of-support page says eligible Windows 10 Home or Pro PCs can upgrade for free to the matching Windows 11 edition; Windows Update should offer it, and you can look under Settings, Privacy and Security, Windows Update. Many "failed" PCs fail only on TPM or Secure Boot being switched off in firmware. That is worth checking with a technician before you condemn a machine, though changing firmware settings carries risk, so back up first.

Step 2: pick your path

The Linux option is real but not for everyone. If your use is browsing, email and documents, our Linux for small business as a free Windows 10 alternative guide explains what works and what does not. It does not suit accounting packages that only run on Windows.

Step 3: schedule it

Work backwards from October 12, 2027. If you have more than ten PCs, spread the replacements across quarters so you do not hit a supply crunch or a cash-flow wall in September 2027. Keep ESU for the PCs scheduled last, and drop it where the machine is already replaced.

How to upgrade a compatible PC safely

1. Back up files and, for Windows settings and apps, use Windows Backup to OneDrive if you use it (Microsoft lists this on its end-of-support page). Keep a second copy on an external drive.
2. Check key software for Windows 11 support: accounting, tax, printers and scanners, and any specialized tool.
3. Update Windows 10 fully, then look in Windows Update for the Windows 11 offer.
4. Run the upgrade at a quiet time. It can take an hour or more depending on the drive.
5. Afterwards, run Windows Update again, confirm printers and backups work, and read our Windows 11 25H2 update guide for what to expect on current builds. If the new system feels sluggish, our how to speed up Windows 11 guide helps.

Three realistic scenarios (illustrative)

These are illustrative examples, not real client stories. Numbers use the Microsoft rules above in US dollars.

Scenario 1: retired couple, two home PCs. One laptop is three years old and passes the check; the other is a nine-year-old desktop that does not. They upgrade the laptop for free. For the desktop they use one consumer ESU enrollment through settings sync at $0, back up the photos, and plan to retire the desktop before October 12, 2027. Total cash outlay: $0 for software, plus the cost of a replacement later.

Scenario 2: six-person accounting office. Four PCs pass the check and are upgraded over a weekend. Two older PCs fail. The owner buys commercial ESU for those two. Buying now means paying Year One plus Year Two under Microsoft's cumulative rule, so about 2 x $183 = $366 USD, and schedules two replacement PCs for the next quarter. They record the decision for their cyber insurer.

Scenario 3: 25-PC small business, mixed ages. An audit shows 14 PCs pass, 8 fail but are under six years old, and 3 are fully obsolete. The firm upgrades the 14, replaces the 3 immediately, and covers the 8 with commercial ESU while budgeting replacements over the next year: 8 x $183 = $1,464 USD. That avoids a single large capital hit while keeping every machine patched.

Official resources to check yourself

Microsoft pages change. Before you pay, open these directly (type the address or use the links below) and confirm that nothing has moved since our November 5, 2026 check.

• Microsoft: Windows 10 Consumer Extended Security Updates program (enrollment methods, price, requirements, end date).
• Microsoft: End of support for Windows 10 (FAQ) (what happens, Windows 11 upgrade, trade-in and recycling options).
• Microsoft Learn: ESU program for Windows 10 (organization pricing rules and limits).
• Microsoft Learn: Enable Windows 10 ESU (keys, activation, slmgr verification).
• Microsoft: Windows 11 specifications (minimum requirements and PC Health Check).

Microsoft's end-of-support page also lists trade-in and recycling programs in qualifying markets, naming Canadian retailers and several PC manufacturers. If your old PC is going out the door, wipe it properly first and use a verified recycling channel.

When to call a professional

You can handle a single personal PC yourself with this guide. Get help when:

• The ESU prompt never appears and you have checked the list above.
• You manage more than about five PCs and need licensing, activation and a replacement schedule.
• A PC fails the Windows 11 check only on TPM or Secure Boot, and you are not comfortable changing firmware settings.
• You suspect you already clicked a fake ESU pop-up or gave remote access to a stranger.
• You need a written decision record for an insurer, accountant or Law 25 file.

IT Cares has provided remote support, and on-site support in Quebec, since 2014. A technician can connect to your PC, run the compatibility check, confirm enrollment status, plan the upgrade and explain each step while you watch. You can book a session online, review our pricing page, or call 1 (888) 711-9428. If you only want a second opinion on the plan, our single 60-minute Expert Consultation is $119.99 CAD.

We do not resell Windows licenses and we do not unlock or crack anything. We will tell you plainly if a PC is better replaced than patched, even when that means the cheapest path for you is not ESU at all.
