Windows 11 24H2 End of Support: What to Do

Published October 13, 2026 13 min read

If your computer is running
Windows 11 version 24H2,
an important update deadline
is approaching.Microsoft has announced that
Windows 11 24H2 Home and Pro
will reach the end of monthly
updates on October 13, 2026.
That means these editions will
no longer receive their normal
monthly security and quality
updates after the servicing period ends.

The good news is that Windows 11
itself is not ending support.
Eligible users can move to a
newer supported version,
including Windows 11 25H2.

This guide shows you how to check
your current version, update safely,
troubleshoot an update that isn’t
appearing, and protect important
files before making changes.

When Does Windows 11 24H2 Support End?

Quick Answer

Microsoft says Windows 11 version
24H2 Home and Pro reaches
end of updates on October 13, 2026.
Its lifecycle listing records
October 14, 2026 as the formal
end date for these editions.

After the servicing period,
Home and Pro devices still
running 24H2 will no longer
receive normal monthly security
updates or routine quality fixes.

Windows 11 24H2 Enterprise and
Education editions have a
different support timeline,
running until October 12, 2027.

This is an end-of-support event
for a specific Windows 11 version,
not the end of Windows 11
as an operating system.

For most personal computers
still using 24H2 Home or Pro,
the practical next step is
to install an eligible,
supported feature update
through Windows Update.

Windows 11 24H2 and 25H2 Support Dates

24H2 Home and Pro

October 13, 2026

Microsoft’s announced
final day of regular updates
for Windows 11 version 24H2
Home and Pro.

25H2 Home and Pro

October 13, 2027

Published support end date
for Windows 11 version 25H2
Home and Pro.

Why Do Some Microsoft Pages Show October 14?

Microsoft’s Windows Update announcement
identifies October 13, 2026 as
the end-of-updates date.
Its Windows 11 Home and Pro
lifecycle table lists
October 14, 2026 as the
formal version end date.

Both refer to the same
October 2026 servicing transition.
Don’t treat the one-day
difference as an extra
month of security coverage.

How to Check If Your PC Is Running Windows 11 24H2

You can check your exact
Windows version using
two built-in methods.

Method 1: Use winver

Check Windows Version

Press Windows + R.
Type winver.
Press Enter.
Read the Version field.
Check whether it says 24H2, 25H2 or another version.

Method 2: Open Windows Settings

Find Your Windows Specifications

Open Settings.
Select System.
Scroll down to About.
Find Windows specifications.
Review Edition and Version.

If your device reports
Windows 11 24H2 Home or Pro,
the October 2026 deadline
applies to that installed version.

If it reports 25H2 or a
newer supported version,
follow the lifecycle
information for that version.

What Happens When Windows 11 24H2 Reaches End of Support?

Windows 11 version 24H2
does not automatically stop
working when its support
period ends.

You should still be able
to start the computer,
open local files and
use applications that
continue to support
your environment.

However, the unsupported
Home and Pro version
will no longer receive
normal monthly security
and quality updates.

Question	After 24H2 End of Support
Will Windows still start?	Yes, the operating system does not automatically shut down
Will my files be deleted?	No, end of support itself does not delete personal files
Will normal security updates continue?	Not for unsupported 24H2 Home/Pro installations
Can my applications still work?	Many can, depending on each publisher’s compatibility policy
Can I install a newer Windows 11 version?	Yes, if a supported update is available and your device is eligible

Is Windows 11 24H2 Still Safe After October 2026?

An unsupported version becomes
more exposed to security risks
as new vulnerabilities
are discovered without
corresponding fixes.

Antivirus protection and
careful browsing can help
reduce some risks, but
they do not replace
operating-system
security updates.

Moving to a supported
Windows 11 version
is the preferred
long-term approach.

How to Update Windows 11 24H2 to 25H2

For supported computers,
Windows Update is the
recommended starting point.

Windows 11 versions 24H2
and 25H2 share a common
operating-system foundation.
Microsoft delivers 25H2
to eligible 24H2 computers
using an enablement package,
which can reduce installation
time compared with a
full operating-system upgrade.

Step-by-Step Update Guide

Save your work and back up important files.
Connect a laptop to a reliable power source.
Open Settings.
Select Windows Update.
Click Check for updates.
Install available quality updates if required.
If Windows 11 version 25H2 is offered, select its download and installation option.
Follow the on-screen instructions.
Restart when prompted.
Use winver to confirm the installed Windows version.

Some computers may be offered
a newer supported version
instead of 25H2.
Follow the release offered
through the supported
Windows Update channel.

Technical Note: Enablement Package

Microsoft documents
KB5054156 as the
25H2 enablement package
for eligible 24H2 devices.
It enables the newer
feature version using
the shared servicing base.

For most home users,
there is no need to
manually download this
package when Windows
Update provides the
appropriate feature update.

Official reference:

Microsoft — Windows 11 25H2 Enablement Package
.

Why Is Windows 11 25H2 Not Showing in Windows Update?

A feature update may not
appear immediately on
every compatible computer.

Microsoft uses staged
rollouts and compatibility
protections to reduce
the risk of update
failures on affected
hardware and software.

Common Reasons the Update Is Missing

The update is being offered gradually.
The computer still needs prerequisite quality updates.
A driver or application compatibility issue is being investigated.
A safeguard hold is preventing the feature update.
The computer is managed by an organization’s update policy.
The device is not currently eligible for the offered version.

What Should You Check First?

Safe Checks

Restart the computer normally.
Open Settings > Windows Update.
Install any applicable quality updates.
Check for the feature update again.
Review Windows Update messages about compatibility.
Check the manufacturer’s official driver and firmware guidance.
Review Microsoft’s Windows release health information for known issues.

Do Not Force a Blocked Update

A safeguard hold is used
to prevent devices with
known compatibility
problems from receiving
a feature update.

Avoid registry changes
or unofficial tools
that bypass protections
without addressing the
underlying compatibility issue.

Microsoft — Safeguard Holds for Windows

Windows 11 Update Not Installing? What to Check

If Windows 11 25H2 appears
but fails during download
or installation, start
with the error message
rather than repeating
the update indefinitely.

Symptom	Possible Explanation	Next Step
Download does not finish	Connectivity or update-service problems	Check internet access and Windows Update status
Insufficient storage message	Not enough available system drive space	Safely review storage and temporary files
Installation error code	Specific update or system problem	Record the code and consult Microsoft guidance
Update rolls back	Possible driver or application conflict	Review update history and known issues
Update not offered	Rollout, policy or safeguard hold	Check release health and device eligibility

Use the Windows Update Troubleshooter

Windows 11 Troubleshooting

Open Settings.
Select System.
Open Troubleshoot.
Select Other troubleshooters.
Find Windows Update.
Run the troubleshooter if it is available on your version.
Follow the recommended actions.
Restart and review Windows Update again.

If the update still fails,
record the error code
and any rollback message.
These details help narrow
down the next diagnostic step.

Avoid Unnecessary High-Risk Fixes

Do not reinstall Windows,
delete system folders,
disable security protections
or update BIOS firmware
solely because a feature
update did not appear.

Back up important files
before attempting
advanced repairs.

How to Prepare Your PC Before a Windows 11 Feature Update

Even a streamlined update
can encounter unexpected
software or hardware issues.
A few preparation steps
reduce unnecessary risk.

Pre-Update Checklist

Back up documents, photos and essential files.
Confirm that important applications support the target Windows version.
Check available free space on the system drive.
Keep laptop power connected throughout the installation.
Allow required updates and restarts to finish.
Save any required recovery or BitLocker information in a secure, accessible location.
Disconnect unnecessary peripherals if recommended for troubleshooting.
After updating, verify files, applications, printers and other devices.

Will Updating to 25H2 Delete My Files?

A normal supported
feature update is
designed to preserve
personal files and
installed applications.

However, no installation
process is completely
free from risk.
Maintain a recent
backup before updating.

Should You Use an Installation Assistant?

Windows Update is usually
the first option to check.
Alternative installation
methods should be chosen
only when appropriate for
your device and Microsoft’s
current instructions.

Do not use an alternative
installation method simply
to bypass a known
compatibility hold.

Should You Install Windows 11 25H2 or a Newer Version?

Windows 11 25H2 provides
a supported upgrade path
for eligible 24H2 computers.
Microsoft has also
documented newer Windows 11
feature versions.

That does not mean every
new version is immediately
offered to every PC.
Availability depends on
the supported rollout
channel, device eligibility
and compatibility.

For a normal home PC,
review the supported
version offered by
Windows Update instead
of forcing a particular
release number.

If your computer already
runs a newer supported
Windows 11 version,
the 24H2 deadline
is not directly applicable.

What About Business and School Computers?

Windows 11 version 24H2
Enterprise and Education
editions have a different
support timeline from
Home and Pro.

Microsoft lists their
support through
October 12, 2027.

Business-managed computers
may also receive feature
updates according to
IT-managed policies,
testing and deployment
schedules.

For Managed Devices

If your computer belongs
to a company, school
or other organization,
contact your IT
administrator before
installing a feature
update manually.

Important business software,
security tools and devices
may need compatibility
validation first.

What Is the Best Next Step for Your Windows 11 PC?

Your Situation	Recommended Starting Point
Windows 11 24H2 Home/Pro	Check for an available supported feature update
Windows 11 25H2	Continue normal Windows Update maintenance
Feature update not offered	Review update status, eligibility and safeguard holds
Installation repeatedly fails	Record the error and investigate the specific cause
Critical work applications	Check compatibility and backup readiness before updating
Company-managed computer	Follow your IT administrator’s deployment plan

For most supported home PCs,
the goal is straightforward:
move away from an unsupported
24H2 installation while
protecting files and
application compatibility.
