Windows 10 Security Updates Extended to 2027: How to Keep Your PC Protected for Free

Still using Windows 10 in 2026? You may have heard that Microsoft has officially ended support for the operating system, leaving millions of computers potentially exposed to security threats.

The good news is that Windows 10 users can continue receiving important security updates until October 12, 2027, provided their devices qualify for Microsoft’s Extended Security Updates (ESU) program.

Even better, eligible home users can enroll at no additional cost by enabling Windows settings synchronization with their Microsoft account.

But there’s a catch: These updates aren’t automatically available to every Windows 10 PC. You need to meet specific requirements and complete the enrollment process.

In this guide, we’ll explain how Windows 10 ESU works, how to activate free security updates, and what to do if the enrollment option is missing.

Is Windows 10 Still Supported in 2026?

Microsoft officially ended standard support for Windows 10 on October 14, 2025.

That means the operating system no longer receives regular feature updates, non-security improvements, or standard technical support.

However, Microsoft offers a separate program called Extended Security Updates (ESU).

This program delivers critical and important security patches to eligible Windows 10 computers, reducing their exposure to newly discovered vulnerabilities.

Microsoft has confirmed that consumer ESU coverage continues through October 12, 2027.

If you enrolled previously, your coverage automatically continues until that date. You don’t need to register again.

There are some important limitations, though.

ESU does not include:

New Windows features or major improvements.
Regular non-security bug fixes.
Microsoft technical support.
A permanent extension of Windows 10’s lifecycle.

Think of ESU as a temporary security lifeline, not a full replacement for a supported operating system.

Official confirmation: Microsoft Windows 10 Extended Security Updates

Who Is Eligible for Free Windows 10 Security Updates?

Before enrolling, check that your computer meets Microsoft’s requirements.

The consumer ESU program supports Windows 10 version 22H2 running these editions:

Windows 10 Home
Windows 10 Pro
Windows 10 Pro Education
Windows 10 Pro for Workstations

Your computer must also have the latest applicable Windows updates installed, including the ESU licensing preparation package KB5126256.

Additionally, enrollment requires an adult Microsoft account with administrator privileges.

The free consumer program is intended for personal computers. Devices managed through an organization’s domain, Microsoft Entra join, or mobile device management generally aren’t eligible for consumer ESU.

Business users should consult their IT administrator about commercial ESU licensing.

Check Your Windows 10 Version

Not sure which version you’re running?

Press Windows + R to open the Run dialog.
Type winver and press Enter.
Look for Version 22H2 in the About Windows window.
Confirm that Windows 10 is installed.

Alternatively, navigate to Settings > System > About to find your Windows specifications.

If you’re running an older version, update to Windows 10 22H2 before attempting enrollment.

How to Get Windows 10 Security Updates for Free Until 2027

Follow these steps to activate Microsoft’s Extended Security Updates program.

Step 1: Install the Latest Windows Updates

First, ensure your system is fully updated.

Open the Start menu.
Click Settings.
Navigate to Update & Security > Windows Update.
Select Check for updates.
Install available applicable updates.
Restart your computer when prompted.

For devices not yet enrolled, Microsoft now requires the ESU Licensing Preparation Package, KB5126256, released in September 2026.

This package must be installed after a Windows 10 security update released on or after October 14, 2025.

It is normally delivered through Windows Update when prerequisites are met.

Important: Installing KB5126256 does not activate ESU by itself. You must still enroll.

You can find more information on Microsoft’s official KB5126256 support page.

Step 2: Open the ESU Enrollment Tool

Once your system is updated:

Return to Settings > Update & Security > Windows Update.
Look for the Extended Security Updates enrollment option.
Click Enroll now.

The ESU enrollment wizard should open.

If this option is missing, check the troubleshooting section later in this article.

Step 3: Sign In With Your Microsoft Account

Microsoft requires a Microsoft account to enroll in consumer ESU.

If you already use one to sign in to Windows, continue with that account.

If your PC uses a local account, Windows will ask you to sign in with a Microsoft account during enrollment.

Make sure the account has administrator privileges and isn’t a child account.

Your ESU entitlement will be associated with this Microsoft account.

Step 4: Select the Free Enrollment Option

Microsoft currently provides three enrollment methods:

Free enrollment: Sync your Windows PC settings using your Microsoft account.
Microsoft Rewards: Redeem 1,000 Rewards points.
Paid enrollment: Make a one-time payment of $30 USD or the local equivalent, plus applicable tax.

For most eligible home users, the first option is the simplest.

If you aren’t already synchronizing your Windows settings, the wizard can offer to enable that functionality.

Follow the instructions to activate settings backup and select the no-additional-cost enrollment option.

Depending on your region, available choices and account requirements may differ. Check the choices displayed on your own PC.

Step 5: Complete Enrollment

Finish the enrollment wizard and wait for confirmation.

Once your device is successfully enrolled, eligible security updates will arrive through Windows Update.

Microsoft allows a consumer ESU entitlement to cover up to 10 eligible devices, using the same Microsoft account.

To enroll another PC, open Windows Update on that device, select Enroll now, and follow the instructions to add it using your existing entitlement.

How to Check Whether Windows 10 ESU Is Activated

After enrollment, it’s worth confirming that your PC is receiving security updates.

Open Settings > Update & Security > Windows Update and review any ESU enrollment information displayed.

If you’ve just completed the process, look for the enrollment confirmation.

Select Check for updates.
Install any available applicable ESU security patches.
Open View update history to inspect recently installed updates.

Remember that a normal Windows Update history alone isn’t definitive proof of ESU enrollment. The enrollment confirmation is important.

If your computer was previously enrolled, Microsoft says the existing coverage automatically continues through October 12, 2027.

Windows 10 ESU Enrollment Not Showing? Try These Fixes

Some users may encounter missing enrollment options, account restrictions, or update installation problems.

Here’s what to check.

Fix 1: Confirm You’re Running Version 22H2

The consumer ESU program requires Windows 10 22H2.

Open winver and check the version number.

If you’re running an older Windows 10 release, update your operating system first.

Fix 2: Check for Missing Updates

Missing prerequisites can prevent enrollment.

Return to Windows Update and install applicable updates, particularly the required ESU licensing preparation package.

You can check View update history for KB5126256.

If the package hasn’t appeared, consult Microsoft’s official KB article rather than downloading installers from unknown third-party websites.

Fix 3: Check Your Microsoft Account

Make sure you’re using a personal Microsoft account with administrator privileges.

A child account cannot enroll in consumer ESU.

Computers controlled by employers or schools may require commercial enrollment instead.

Fix 4: Restart and Check Again

After installing updates or changing account settings, restart Windows.

Then return to Windows Update and check whether the enrollment link appears.

If the enrollment wizard opens and immediately closes, install the latest Windows updates. Microsoft previously addressed an ESU wizard-loading issue through a Windows 10 update.

Fix 5: Check Whether You’re Already Enrolled

If you previously activated ESU, you don’t need to enroll again.

Microsoft automatically extends existing consumer coverage through October 2027.

Don’t purchase another entitlement simply because the original enrollment option is no longer visible.

How to Enable Windows Settings Backup for Free ESU

If Windows doesn’t offer free enrollment immediately, review your settings synchronization configuration.

Navigate to:

Settings > Accounts > Windows backup

Look for settings related to remembering your apps and preferences.

You can also open the Windows Backup application from the Start menu and review its settings backup options.

Windows Backup can synchronize settings such as preferences, accessibility options, personalization, and certain account information.

Privacy note: Settings synchronization is different from automatically uploading every personal file. Review the available backup options carefully, especially OneDrive folder backup, before enabling them.

For detailed instructions, see Microsoft’s Windows Backup documentation.

Is Windows 10 Safe to Use Until October 2027?

An enrolled Windows 10 computer is generally better protected than an unsupported Windows 10 computer receiving no operating-system security patches.

However, ESU doesn’t eliminate every security risk.

To improve your protection:

Install security updates promptly.
Keep your browser and installed applications updated.
Enable a reputable antivirus solution.
Use strong, unique passwords and multifactor authentication.
Avoid suspicious downloads and email attachments.
Maintain regular backups of important files.

Be particularly careful with outdated applications that may have reached their own end-of-support dates.

ESU protects against certain Windows vulnerabilities, but it cannot compensate for every insecure program or unsafe browsing habit.

Should You Keep Windows 10 or Upgrade to Windows 11?

ESU gives Windows 10 users extra time, but it shouldn’t be viewed as a permanent solution.

If your computer supports Windows 11, upgrading is generally the better long-term option.

Windows 11 continues to receive feature improvements and security updates within its supported lifecycle.

To check compatibility, use Microsoft’s PC Health Check application.

Open the application and select Check now to see whether your computer meets Windows 11 requirements.

If your device isn’t compatible, you have several alternatives:

Continue using Windows 10 temporarily with ESU.
Replace the computer with a supported Windows 11 device.
Consider a supported Linux distribution if your hardware and software needs allow it.

Linux Mint, Ubuntu, and other beginner-friendly Linux distributions may be worth exploring for older computers.

Before switching operating systems, verify compatibility with your essential applications, printers, and other peripherals.

Final Thoughts

Windows 10’s end of standard support doesn’t mean your existing computer has suddenly become unusable.

Microsoft’s Extended Security Updates program provides a valuable temporary option for people who aren’t ready to upgrade or replace their PCs.

With eligible consumer coverage available through October 12, 2027, there’s still an opportunity to secure your system without paying an additional enrollment fee.

The most important steps are straightforward: update Windows 10 to version 22H2, install the required updates, sign in with an eligible Microsoft account, and complete ESU enrollment.

If you plan to keep using Windows 10, don’t delay those security updates.
