Quick Answer

Microsoft Extended Security Updates (ESU) is a paid Microsoft program that allows eligible customers to continue receiving certain critical and important security updates after a Microsoft product reaches its normal end of support.

For the standard Windows 10 release, the current ESU program applies to Windows 10 version 22H2. Windows 10 reached its normal end of support on October 14, 2025. Enrolled Windows 10 22H2 devices can continue receiving eligible security updates through the ESU program while organizations and users transition to Windows 11 or another supported platform.

For consumer PCs, Microsoft currently provides Windows 10 ESU coverage through October 12, 2027. Commercial and educational customers can have Windows 10 ESU coverage for up to three years after Windows 10's end of support, subject to Microsoft's licensing and eligibility requirements.

ESU is important because Windows 10 continues to work after end of support, but without ESU it no longer receives normal security updates. ESU is therefore intended as a temporary bridge rather than a replacement for upgrading to a supported operating system.

What Is Microsoft's Extended Security Updates (ESU) Program?

Extended Security Updates, commonly called ESU, is Microsoft's mechanism for providing security updates for certain products after their normal support lifecycle has ended.

Microsoft describes ESU as a temporary bridge for customers that need additional time to migrate from an older product to a newer supported platform. ESU does not restart or extend the normal product lifecycle. Instead, it provides a limited period during which eligible devices can continue receiving specified security updates.

For Windows 10, this became particularly relevant when Microsoft ended standard support on October 14, 2025.

After that date, a normal Windows 10 installation continues to operate, but Microsoft no longer provides regular security and feature updates for the standard Windows 10 release unless the device is covered by an applicable program such as ESU.

In simple terms

Think of ESU as a security bridge:

Windows 10 normal support → End of support → ESU security coverage → Migration to Windows 11 or another supported platform

It is not intended to turn Windows 10 into a fully supported modern operating system indefinitely.

Why Did Microsoft Introduce Windows 10 ESU?

Windows 10 has a very large installed base, and not every computer can immediately move to Windows 11.

Some computers may:

fail Windows 11 hardware requirements;
require additional testing before an upgrade;
run business applications that need compatibility testing;
be part of a larger enterprise deployment;
require replacement hardware;
need additional time for migration planning.

Without ESU, continuing to operate a Windows 10 system after October 14, 2025 means operating without the normal security updates Microsoft provides for supported Windows versions.

ESU gives eligible customers additional time to complete their transition.

Which Windows Versions Does ESU Support?

This is one of the most important points to understand.

Standard Windows 10 ESU

The current Windows 10 ESU program is based on:

Windows 10 version 22H2

Microsoft's Windows 10 release information identifies version 22H2 as the final general-availability Windows 10 release and the version covered by the standard Windows 10 ESU program.

For consumer devices, Microsoft lists these Windows 10 22H2 editions as eligible:

Windows edition	Consumer ESU eligibility
Windows 10 Home 22H2	Yes
Windows 10 Pro 22H2	Yes
Windows 10 Pro Education 22H2	Yes
Windows 10 Pro for Workstations 22H2	Yes
Windows 10 Enterprise 22H2	Commercial/organizational ESU arrangements apply
Windows 10 Education 22H2	Commercial/education ESU arrangements apply
Windows 10 versions other than 22H2	Not eligible for the standard Windows 10 ESU program

Microsoft's consumer ESU requirements specifically identify Windows 10 version 22H2 Home, Professional, Pro Education and Pro for Workstations editions. Commercial deployments have separate licensing and activation requirements.

What about Windows 11?

Windows 11 is not covered by the Windows 10 ESU program.

Windows 11 has its own product lifecycle and support periods. ESU is generally associated with products that have reached, or are approaching, their normal support end date.

Therefore, installing Windows 11 does not mean that you need Windows 10 ESU.

What About Windows 10 Enterprise LTSC and LTSB?

This is an important exception.

Not every Windows 10 edition follows the same lifecycle as Windows 10 22H2.

Microsoft has separate lifecycle arrangements for Windows 10 Enterprise LTSC/LTSB releases. Some of these releases have support dates extending beyond the normal October 14, 2025 Windows 10 end-of-support date.

For example:

Windows 10 release	Lifecycle situation
Windows 10 22H2	Standard Windows 10 support ended October 14, 2025; ESU available
Windows 10 Enterprise LTSC 2021	Support continues until January 12, 2027; separate lifecycle
Windows 10 IoT Enterprise LTSC 2021	Support continues until January 13, 2032
Windows 10 Enterprise LTSC 2019	Extended support through January 9, 2029
Windows 10 Enterprise LTSB 2016	Extended support through October 13, 2026

These LTSC/LTSB products have their own lifecycle rules, so they should not automatically be treated as ordinary Windows 10 22H2 installations.

Important: Windows 10 Enterprise LTSC 2021 and Windows 10 IoT Enterprise LTSC 2021 are different products with different lifecycle dates. Microsoft specifically notes that Windows 10 Enterprise LTSC 2021 ends servicing on January 12, 2027, while Windows 10 IoT Enterprise LTSC 2021 continues until January 13, 2032.

How Long Does Windows 10 ESU Last?

The answer depends on the type of customer and licensing arrangement.

Consumer Windows 10 ESU

For eligible consumer devices, Microsoft currently provides ESU coverage through:

October 12, 2027

Consumer enrollment is available until the program ends, although Microsoft recommends enrolling rather than continuing to use an unprotected Windows 10 installation after support ended.

Commercial and educational organizations

Microsoft's general ESU framework allows enrolled commercial and educational Windows 10 PCs to receive security updates for up to three years after Windows 10 end of support, subject to the applicable licensing arrangement.

For the standard Windows 10 ESU lifecycle, Microsoft lists:

Year 1: through October 13, 2026
Year 2: through October 12, 2027
Year 3: through October 10, 2028

The actual licensing method and availability depend on the customer's environment and Microsoft licensing agreement.

What Security Updates Does ESU Provide?

Windows 10 ESU provides eligible devices with critical and important security updates as defined under Microsoft's security servicing process.

Microsoft states that these updates are intended to help protect eligible Windows 10 devices against security vulnerabilities after normal support ends.

For example, Microsoft continues publishing security updates for Windows 10 ESU devices after October 2025. Current Microsoft update documentation shows Windows 10 22H2 ESU among the applicable products for 2026 security updates.

Does ESU provide all Windows updates?

No.

ESU is specifically focused on security updates.

It does not mean that Windows 10 will continue receiving the same complete servicing experience it received during normal support.

What Is Not Included With ESU?

Microsoft specifically states that ESU does not include:

New features
Customer-requested non-security updates
Design change requests
Normal product lifecycle extension
General technical support for Windows after its normal end of support

Microsoft's ESU documentation also makes clear that ESU should be viewed as a temporary solution rather than a long-term replacement for migration to a supported platform.

ESU does not turn Windows 10 into Windows 11

This distinction is important.

Installing ESU does not:

upgrade Windows 10 to Windows 11;
add Windows 11 features;
change Windows 10's user interface into Windows 11;
remove Windows 11 hardware requirements;
extend every aspect of Microsoft's normal Windows 10 support.

It simply provides the specified security servicing for eligible enrolled systems.

What Are the Main Benefits of Windows 10 ESU?

1. Continued security updates

The biggest benefit is continued access to eligible critical and important security updates after Windows 10's normal support ended.

2. More time to migrate

Organizations may need time to:

test applications;
replace incompatible hardware;
update drivers;
test line-of-business software;
plan deployment;
migrate users in phases.

ESU can provide additional time for those activities.

3. Reduced security exposure compared with unsupported Windows 10

A Windows 10 installation without ESU no longer receives the normal security updates that ended with Windows 10 support.

An eligible and properly enrolled ESU device continues receiving applicable security updates.

This does not make the computer completely risk-free, but it is a materially different security position from running an unsupported installation without security servicing.

4. Avoids rushed hardware replacement

If an organization's existing computers cannot immediately be upgraded to Windows 11, ESU can provide additional time to plan hardware replacement rather than making an immediate, unplanned transition.

5. Supports phased enterprise migration

Large organizations rarely upgrade thousands of computers simultaneously.

ESU can provide a transition period while IT teams migrate systems in stages.

Windows 10 Without ESU vs Windows 10 With ESU

Area	Windows 10 without ESU	Windows 10 with ESU
Windows 10 continues to run	Yes	Yes
Normal Windows 10 support	No	No
Eligible critical security updates	No	Yes
Eligible important security updates	No	Yes
New Windows features	No	No
New feature improvements	No	No
General technical support	No	No
Temporary migration bridge	No	Yes

The table describes the standard Windows 10 situation after October 14, 2025; specific LTSC/LTSB products have separate lifecycle arrangements.

Consumer Windows 10 ESU: Who Is Eligible?

Microsoft's current consumer requirements include:

Windows 10 version 22H2;
Home, Professional, Pro Education or Pro for Workstations edition;
latest Windows update installed;
required Windows 10 ESU Licensing Preparation Package;
Microsoft account with administrator privileges for enrollment.

Microsoft currently identifies KB126256 as the consumer ESU Licensing Preparation Package. Microsoft has also published subsequent ESU-related licensing preparation packages, so administrators should use the current package applicable to their deployment rather than relying on an old KB number indefinitely.

Consumer ESU has usage restrictions

Microsoft states that the consumer ESU program cannot be used for certain commercial scenarios.

For example, enrollment is not offered for devices that are:

joined to an Active Directory domain;
joined to Microsoft Entra in the applicable commercial configuration;
enrolled in MDM;
operating in kiosk mode;
already covered by an ESU license.

Microsoft notes that Microsoft Entra-registered devices can use the consumer program, which is different from being joined to Microsoft Entra.

Organizations should therefore use the appropriate commercial ESU licensing and deployment process rather than attempting to use the consumer enrollment mechanism.

How Can a Home User Enroll in Windows 10 ESU?

For eligible consumer devices, Microsoft provides an enrollment option through Windows Update.

Step 1: Check the Windows version

Press:

Windows + R

Enter:

winver

The Windows information window should show Windows 10, Version 22H2.

You can also check:

Settings → System → About

Look for the Windows specifications section.

Step 2: Install the latest Windows updates

Go to:

Settings → Update & Security → Windows Update

Select:

Check for updates

Install the available updates and restart the computer if requested.

Step 3: Look for the ESU enrollment option

Microsoft's consumer process provides an Enroll now option through Windows Update on eligible devices.

If the device satisfies the prerequisites, Windows should present the applicable ESU enrollment process.

Step 4: Sign in with a Microsoft account

Consumer ESU enrollment requires a Microsoft account.

Microsoft states that the account used to enroll must have administrator privileges and cannot be a child account.

Step 5: Complete enrollment

Depending on the region and eligibility, Microsoft may present the available enrollment method.

Microsoft currently lists consumer enrollment options that can include:

enrollment at no additional cost when PC settings synchronization requirements are met;
redemption using Microsoft Rewards points;
a one-time purchase of US$30 or local-currency equivalent, plus applicable tax.

Microsoft notes that enrollment options and timing can vary by region.

Is Windows 10 ESU Free?

There is no single answer for every customer.

For consumers, Microsoft currently lists multiple enrollment methods, including:

no additional cost when eligible PC settings synchronization is used;
Microsoft Rewards points;
a one-time purchase of US$30 or local-currency equivalent plus applicable tax.

Regional availability can affect the options shown to a particular user.

For businesses and organizations, ESU is handled through Microsoft's commercial licensing arrangements and should not be assumed to follow consumer pricing.

Do not use consumer pricing as the expected price for a business deployment.

Can You Still Upgrade to Windows 11 After Enrolling in ESU?

Yes.

Microsoft explicitly states that enrolling in Windows 10 ESU does not prevent an eligible PC from being upgraded to Windows 11.

This is one of the practical purposes of ESU: it can provide additional time while the organization or user prepares for the Windows 11 transition.

A typical migration path could therefore be:

Windows 10 22H2
      ↓
Windows 10 ESU
      ↓
Application / hardware compatibility testing
      ↓
Windows 11 upgrade or new PC

How Can You Check Whether Your PC Is Running Windows 10 22H2?

The simplest method is:

Windows + R

Then enter:

winver

Look for:

Version 22H2

You can also use Command Prompt:

winver

This opens the Windows version information window.

For administrators, PowerShell can also be used to inspect Windows information:

Get-ComputerInfo | Select-Object WindowsProductName, WindowsVersion, OsBuildNumber

This command only reads system information and does not modify Windows.

What If My PC Is Running Windows 10 21H2?

For the standard Windows 10 ESU program, 22H2 is the required version.

A normal Windows 10 21H2 installation should not be treated as eligible for the standard Windows 10 22H2 ESU program simply because it is running Windows 10.

Upgrade the device to the applicable supported release before attempting standard Windows 10 ESU enrollment.

There are separate lifecycle considerations for LTSC/LTSB editions, so administrators should first identify the exact Windows edition and servicing channel before changing it.

Does ESU Include Antivirus Protection?

ESU should not be confused with antivirus software.

ESU provides Microsoft's applicable security updates for the operating system. It does not mean that a computer has comprehensive protection against every security threat.

Organizations should continue using appropriate:

endpoint protection;
Microsoft Defender or an approved security product;
firewall controls;
application security controls;
identity protection;
backup procedures;
security monitoring;
least-privilege practices.

ESU reduces exposure to vulnerabilities addressed by the applicable security updates, but it does not eliminate the need for broader cybersecurity controls.

Is ESU a Permanent Solution?

No.

Microsoft describes ESU as a temporary bridge rather than a long-term solution.

Organizations should use the ESU period to work toward an appropriate migration strategy.

That may involve:

upgrading compatible computers to Windows 11;
replacing computers that do not meet Windows 11 requirements;
testing business applications;
updating hardware and drivers;
reviewing legacy applications;
planning phased deployment;
documenting systems that require exceptions.

Windows 10 ESU vs Upgrading to Windows 11

Consideration	Windows 10 ESU	Windows 11
Purpose	Temporary security bridge	Supported modern Windows platform
Requires Windows 10 22H2 for standard ESU	Yes	No
Receives applicable security updates	Yes, during ESU coverage	Yes, according to Windows 11 lifecycle
New Windows 11 features	No	Yes, subject to version/device
Hardware replacement may be required	Not necessarily	May be required
Migration effort	Lower initially	Higher initially
Long-term migration requirement	Still necessary	Avoids remaining on Windows 10
Intended as permanent Windows 10 solution	No	N/A

This is not a ranking of the two options. They serve different purposes: ESU provides additional security coverage while a migration is being completed, whereas Windows 11 is Microsoft's current Windows platform.

Important Security Considerations

Do not assume an unpatched Windows 10 PC is safe

After Windows 10 reached end of support, Microsoft stopped providing normal security updates for the standard release. Microsoft warns that continuing without security updates increases exposure to malware and other security threats.

ESU does not fix every vulnerability

ESU is limited to the security updates covered by the program. It is not a promise that every security problem affecting an application, third-party driver or third-party software will be fixed.

Keep third-party applications updated

Browsers, PDF readers, Java runtimes, business applications and other software can introduce security vulnerabilities independently of Windows.

Maintain backups

ESU does not replace a backup strategy.

For important business computers, maintain tested backups and an appropriate recovery plan.

Do not use unofficial ESU bypasses

Avoid scripts, registry hacks, modified licensing tools or unofficial activation methods claiming to provide ESU without Microsoft's authorization.

Such methods can create security, licensing and update-management problems.

Use Microsoft's supported licensing and enrollment mechanisms.

Common Problems With Windows 10 ESU

ESU option does not appear

Possible causes include:

Windows version is not 22H2;
edition is not eligible for the consumer program;
required Windows updates are missing;
required licensing preparation package is missing;
the device is being used in a commercial scenario that is not eligible for consumer enrollment;
the device is already covered by another ESU license;
regional enrollment conditions differ.

Start by checking the exact Windows edition and version rather than attempting unofficial fixes.

Windows 10 is 22H2 but ESU is still unavailable

Being on 22H2 alone does not guarantee consumer enrollment.

Check:

Windows Update status;
installed updates;
ESU Licensing Preparation Package;
Microsoft account status;
whether the device is domain joined or MDM managed;
whether another ESU license is already associated with the device.

For commercial computers, follow Microsoft's commercial ESU activation requirements instead.

How Organizations Should Approach Windows 10 ESU

For business environments, ESU should ideally be part of a documented migration plan.

A practical approach is:

Step 1: Inventory Windows devices

Identify:

Windows edition;
Windows version;
hardware model;
TPM status;
CPU compatibility;
application dependencies;
business-critical software.

Step 2: Separate compatible and incompatible PCs

Some computers may be able to move directly to Windows 11.

Others may require hardware replacement or another migration strategy.

Step 3: Identify systems that need additional time

Examples include:

specialized workstations;
legacy applications;
computers connected to specialized equipment;
systems awaiting replacement;
systems requiring extended compatibility testing.

Step 4: Use ESU where justified

ESU can be used as a temporary security bridge for eligible systems that cannot immediately migrate.

Step 5: Continue the migration

Do not allow ESU to become an excuse for indefinite postponement.

Maintain a target date for replacing or upgrading the remaining Windows 10 systems.

A Note About Windows 10 LTSC/LTSB

Administrators should be particularly careful when identifying LTSC systems.

The following command can help identify the Windows edition:

winver

You can also use:

Get-ComputerInfo | Select-Object WindowsProductName, WindowsVersion, OsBuildNumber

If the system is an Enterprise LTSC/LTSB edition, check Microsoft's lifecycle information for that specific release before purchasing or deploying standard Windows 10 ESU.

Microsoft maintains separate lifecycle information for LTSC/LTSB releases.

What Happens If You Do Nothing After Windows 10 End of Support?

Windows 10 does not suddenly stop booting on the end-of-support date.

The computer continues to operate.

However, for the standard Windows 10 release, Microsoft no longer provides normal security updates, feature updates or technical support after October 14, 2025.

Therefore, there are three broad situations:

Windows 10 22H2
      │
      ├── Upgrade to Windows 11
      │
      ├── Enroll in applicable ESU
      │       └── Temporary security coverage
      │
      └── Continue without ESU
              └── No normal security updates

The appropriate route depends on the hardware, software, business requirements and applicable Microsoft licensing.

Advantages and Limitations of ESU

Advantages

Provides continued eligible security updates.
Gives users and organizations additional migration time.
Helps reduce exposure to vulnerabilities addressed by Microsoft's security updates.
Can support phased enterprise migrations.
Can delay immediate hardware replacement where migration cannot happen immediately.
Does not prevent an eligible PC from subsequently upgrading to Windows 11.

Limitations

It is temporary.
It does not provide new Windows features.
It does not restore full Windows 10 product support.
It does not cover every possible software or security problem.
Consumer and commercial eligibility rules differ.
Standard Windows 10 ESU requires version 22H2.
LTSC/LTSB editions follow separate lifecycle rules.
ESU should not be treated as a permanent replacement for migration.

When Should You Consider ESU?

ESU can be relevant when:

a Windows 10 PC cannot immediately move to Windows 11;
a business application needs additional testing;
hardware replacement is planned but not yet complete;
an organization needs a phased migration;
a legacy workstation requires additional transition time.

When Should You Not Rely on ESU?

ESU should not be treated as a reason to indefinitely postpone modernization.

If a computer can be upgraded to a supported Windows 11 configuration and the required applications and hardware are compatible, organizations should include that upgrade in their normal lifecycle planning.

Likewise, computers that are too old to provide an acceptable secure and supported computing environment may need replacement rather than indefinite continuation through ESU.

Best Practices for Windows 10 ESU

Confirm the exact Windows edition and version.
Update Windows before attempting enrollment.
Use Microsoft's official ESU enrollment or licensing process.
Do not use unofficial activation or bypass tools.
Maintain antivirus and endpoint security controls.
Keep third-party applications patched.
Maintain tested backups.
Document every system covered by ESU in a business environment.
Set a migration or replacement deadline.
Review Microsoft's current lifecycle and ESU documentation periodically because eligibility, packages and licensing details can change.

Key Takeaway

Microsoft's Extended Security Updates (ESU) program gives eligible customers a temporary way to continue receiving important security updates after a Microsoft product reaches its normal end of support.

For the standard Windows 10 release, the key version is Windows 10 version 22H2. Windows 10 reached end of support on October 14, 2025, and eligible ESU-enrolled devices can continue receiving applicable security updates during the ESU period. Consumer coverage currently runs through October 12, 2027, while commercial and educational customers can have coverage for up to three years after Windows 10's end of support under applicable licensing arrangements.

ESU should therefore be viewed as a temporary security bridge, not as an extension of Windows 10's complete product support lifecycle. Organizations should use the additional time to upgrade compatible PCs to Windows 11, replace incompatible hardware, and complete their migration planning.

The appropriate choice depends on hardware compatibility, applications, business requirements and migration plans.

19. How do I check whether my Windows 10 PC is 22H2?

Press Windows + R, type winver, and press Enter. The resulting dialog shows the Windows version and feature update.

20. Can I continue using Windows 10 without ESU?

Technically, yes—the operating system continues to function. However, standard Windows 10 no longer receives normal security updates after October 14, 2025, which increases security exposure.

Final Recommendation / Conclusion

Windows 10 ESU is best understood as a temporary security bridge for eligible Windows 10 systems, not as a permanent extension of Windows 10's normal support lifecycle.

For the standard Windows 10 release, version 22H2 is the important requirement. If a computer cannot yet move to Windows 11, ESU can provide additional security-update coverage while the user or organization completes hardware replacement, application testing or migration. For eligible consumers, Microsoft's current ESU period runs through October 12, 2027; commercial and educational customers have separate licensing arrangements that can provide coverage for up to three years after Windows 10's end of support.

IT administrators should also avoid treating every Windows 10 installation identically. Enterprise LTSC/LTSB editions have separate lifecycles, and their support dates can differ substantially from standard Windows 10 22H2.

The practical approach is to identify the exact Windows edition and version, determine whether the device is eligible for ESU, keep the system fully updated, and use the ESU period to complete migration to a currently supported Windows platform.
