Why now is the right time to upgrade to Windows 11

Although your systems won’t suddenly stop working the day Microsoft ends support for Windows 10, the downstream effects will be far greater than many organisations expect.

Based on past Microsoft transitions, we know that delaying an upgrade to Windows 11 leads to escalating challenges. Costs increase, compliance weakens, and PC performance drops over time. In the long run, the dangers of staying on unsupported systems heavily outweigh the upfront investment of moving to the latest version of Windows.

Here’s what to consider when planning your Windows 10 upgrade process:

Security exposure grows after patches end

Once Windows Update stops providing fixes, every unsupported computer becomes more vulnerable. Windows 10 support officially ends on 14 October 2025, after which Microsoft will no longer provide updates unless you pay for Extended Security Updates (ESU) – available until 13 October 2026, but not free by default.

History proves the risks of waiting. When Windows 7 reached end-of-life, the UK government spent £5.5 million on ESU just to keep systems safe.

Security implications and risk assessment

After end-of-support, attackers increasingly target legacy systems. Following Windows 7’s retirement, malware incidents increased by 125% in a single year.

The WannaCry ransomware outbreak in 2017 was a painful example of what can happen when unsupported devices are left unpatched. Entire networks went down because one outdated endpoint provided an entry point.

Modern threats attack deep within the OS, where traditional antivirus or endpoint software struggles to help. By contrast, Windows 11’s new security model – TPM 2.0, secure boot, and virtualisation-based protection – is built into the OS and cannot be added to older versions.

Software and hardware support phases out

• Applications: Business-critical apps and productivity suites may stop receiving security updates if they run on unsupported versions of Windows.
• Browsers: During the Windows 7 transition, browsers only supported the OS for 18 months after end-of-life.
• Drivers: New hardware from laptops to printers, is designed for Windows 11, and many features won’t install or display correctly on Windows 10.

Relying on outdated operating systems ultimately slows down business operations and frustrates users.

Compliance and legal considerations

For regulated sectors, unsupported Windows systems present compliance problems:

• Frameworks like Cyber Essentials and ISO 27001 require supported devices and timely updates.
• Cyber insurance may exclude claims if breaches occur on unsupported systems.
• Client contracts and audits often demand that you run the most current version of the OS.

Ignoring these requirements risks failing audits and damaging stakeholder trust.

Financial impact and hidden costs

While it may seem cheaper to wait, the hidden costs add up:

• Extended Security Updates get pricier each year.
• Without Microsoft support, third-party IT services are needed – often at a much higher cost.
• If you delay too long, you may face emergency migrations with premium charges and downtime.

Planned migrations are always more cost-effective than crisis-driven deployments.

Strategic alternatives and migration options

If an immediate move isn’t possible, you still have choices:

• Extended Security Updates (ESU): A temporary, paid extension until 2026.
• Windows 10 LTSC: Limited to specialist scenarios such as embedded devices.
• Cloud solutions: Windows 365 Cloud PCs or Azure Virtual Desktop let you access the latest version of Windows securely from older hardware.
• Hybrid approaches: Run dual boot or virtualised environments while you phase in upgrades.

Planning your Windows 11 upgrade process

Migrating to Windows 11 takes preparation, but the installation is straightforward with the right tools:

1. Check compatibility – Use Microsoft’s PC Health Check tool to identify which PCs can be upgraded and which require a new PC.
2. Check free disk space – Ensure each laptop or desktop has capacity for the installation files.
3. Back up files – Always recommend backing up data before an upgrade.
4. Choose your method – You can upgrade via Windows Update, the Installation Assistant, or ISO download. Many users simply double-click the installer to begin.
5. Follow instructions – Connect to a reliable internet connection, schedule downtime, and expect at least one restart for the upgrade to complete.
6. Support users – Provide clear instructions and training so staff can quickly adapt to the new display, layout, and features.

With planning, the process doesn’t need to be disruptive.

Final thoughts

The technology landscape is moving on, with software vendors and hardware makers focusing on Windows 11. Remaining on Windows 10 after its support date risks productivity, compliance, and security.

By acting now, you control the schedule, costs, and migration approach rather than being forced into rushed, expensive emergency projects.
