Windows 11 version 24H2 Home and Pro editions will reach end of updates on 13 October 2026—just seven weeks away. If your Kent SME is running either of these editions, your devices will stop receiving security patches, time zone updates, and technical support from Microsoft after that date, leaving your business exposed to rapidly evolving cyber threats.
This is not a distant deadline. It requires immediate action from office managers and business owners across the South East to identify which devices are affected and plan upgrades before support expires.
Windows 11 24H2 Home and Pro Support Ends 13 October 2026
According to Microsoft’s official support documentation, devices running Windows 11 version 24H2 Home and Pro editions will reach end of updates on October 13, 2026, and will no longer receive fixes for known issues, time zone updates, technical support, or monthly security and preview updates containing protections from the latest security threats
.
Enterprise and Education editions remain supported until October 12, 2027
, giving organisations with volume licensing an additional year of coverage.
The timing is particularly significant given the current threat landscape.
Microsoft’s August 2026 Patch Tuesday alone addressed 421 vulnerabilities, including 62 critical and 357 important-severity vulnerabilities
, and
Microsoft argues that large Patch Tuesday updates will become common due to rising AI threats
. Without ongoing security updates, devices running unsupported Windows 11 24H2 Home and Pro editions will be unable to defend against newly discovered vulnerabilities.
Why This Matters for UK SMEs Right Now
The consequences of running unsupported Windows versions extend far beyond technical inconvenience. Here’s what Kent SMEs face if they miss the 13 October deadline:
- No security patches: New vulnerabilities discovered after 13 October 2026 will remain unpatched on affected devices, creating exploitable entry points for attackers.
- Compliance failures: Many cyber insurance policies and regulatory frameworks require organisations to run supported operating systems with current security updates.
- Increased breach risk:
The UK government’s Cyber Security Breaches Survey 2025 found that 43% of businesses and 30% of charities identified a cyber security breach or attack in the previous 12 months
, and running outdated systems significantly increases this risk. - Business continuity issues: Without time zone updates and compatibility fixes, devices may experience unexpected operational problems that Microsoft will no longer support.
This deadline also intersects with Microsoft’s recent recommendation that organisations deploy Windows updates within three days to counter AI-powered vulnerability discovery. Running an unsupported version eliminates your ability to follow this guidance entirely.
Which Devices Are Affected?
Most SMEs use Windows 11 Home or Pro editions on their workstations and laptops. To check which version and edition you’re running:
- Press Windows key + R
- Type winver and press Enter
- Look for “Version 24H2” in the window that appears
- Check whether it says “Home” or “Pro” (or “Enterprise”/”Education”)
If your devices show version 24H2 with either Home or Pro editions, they are affected by the 13 October 2026 end-of-support deadline.
What Kent SMEs Must Do Before 13 October 2026
You have three viable options, and the right choice depends on your current licensing, device capabilities, and business requirements:
1. Upgrade to Windows 11 25H2 or Later
Microsoft recommends upgrading to the latest version of Windows 11 to stay protected and up to date
. Windows 11 version 25H2 (or any subsequent version) will receive ongoing security updates and feature improvements. This is the simplest path for most SMEs running compatible hardware.
The upgrade process typically happens through Windows Update, though IT administrators should test the upgrade on representative devices first and schedule deployment during low-business-impact periods.
2. Move to Enterprise or Education Editions (If You Have Volume Licensing)
Organisations with Microsoft volume licensing agreements may be able to upgrade from Pro to Enterprise edition, which extends support for version 24H2 until 12 October 2027. This provides an additional year before a version upgrade is required, though it requires appropriate licensing.
This option is particularly relevant if your organisation needs additional time to plan and test a major version upgrade, or if specific applications have compatibility concerns with newer Windows 11 versions.
3. Replace Devices That Cannot Run Newer Windows 11 Versions
Some older devices that currently run Windows 11 24H2 may not meet the hardware requirements for newer versions (particularly if they barely met the Windows 11 minimums initially). For these devices, you’ll need to plan hardware replacement before 13 October 2026.
This is also an opportunity to review your device refresh cycles and ensure you’re not repeatedly facing end-of-support emergencies due to aging hardware.
The Broader Context: Rising Patch Volumes and Compressed Response Windows
This end-of-support deadline arrives amid unprecedented pressure on IT teams to manage security updates.
Microsoft’s August 2026 Patch Tuesday was still one of the largest Patch Tuesday totals ever
, following July’s record-breaking release, and
there is no reason to suppose that Patch Tuesday will ever return to the lower volumes we saw prior to 2026
.
The combination of AI-powered vulnerability discovery driving record patch volumes and compressed deployment windows means that maintaining supported operating systems is no longer optional—it’s foundational to cyber security strategy.
The seven technical controls UK insurers now demand from SMEs increasingly include evidence that all devices run supported operating systems with current patches applied within defined timeframes.
How to Plan Your Upgrade Before October
With seven weeks remaining until the deadline, here’s a practical timeline for Kent SMEs:
- Week 1 (Now): Audit all devices to identify which are running Windows 11 24H2 Home or Pro editions. Document hardware specifications and installed applications.
- Week 2-3: Test Windows 11 25H2 upgrade on representative devices from different departments. Identify any application compatibility issues.
- Week 4-5: Create a deployment schedule that prioritises critical business systems and minimises disruption. Ensure backups are current before upgrading production devices.
- Week 6-7: Complete upgrades across all affected devices, verify successful installation, and confirm devices are receiving updates normally.
For organisations with complex environments or limited internal IT resources, engaging professional support now—while there’s still time for proper planning—is significantly less disruptive than emergency responses after the deadline passes.
What Happens If You Miss the Deadline?
Devices still running Windows 11 24H2 Home or Pro editions after 13 October 2026 will continue to function, but they will become progressively less secure with each passing day.
Microsoft warns that delaying critical quality updates with security fixes gives attackers using AI ample time to find and exploit known security gaps, which is why they’ve updated recommendations for deploying Windows updates to less than three days as the deferral period
.
This problem is compounded by the rising sophistication of threats facing UK businesses.
Phishing remains the most common cyber threat facing UK businesses, but in 2026 it has become harder to spot and easier for attackers to scale
, and
attackers are using AI to generate convincing phishing attacks, exploit software supply chains, compromise cloud identities and launch highly disruptive ransomware campaigns
.
Running unsupported systems in this environment significantly increases the likelihood that your organisation will appear in next year’s breach statistics.
