Escalating cyberthreats and the evolving landscape of regulatory compliance are converging at a crucial juncture for organisations still reliant on Windows 10. As the end-of-support (EOS) date for Windows 10 draws nearer, businesses that fail to migrate to Windows 11 face not only operational challenges but also expose themselves to significant security risks. With October 14, 2025, set as the deadline, this transition is no longer a matter of routine IT housekeeping; it has become a foundational imperative for both security and future innovation.
The frequency and sophistication of cyberattacks have accelerated at an unprecedented rate in recent years. Cybercriminals now leverage advanced technologies, most notably artificial intelligence, to automate, personalise, and scale their attacks. These adversaries are adept at exploiting any chink in an organisation’s technological armour, with outdated or unpatched systems representing the easiest pathways. According to independent reporting, the average cost of a data breach in Australia reached a staggering A$4.26 million in 2024, a sum that far exceeds basic compliance penalties and can threaten the viability of even well-resourced businesses.
Between 2021 and 2024, data breach frequency surged by an estimated 119%, and more than 247 million records were compromised in Australia in 2024 alone. While precise figures will always fluctuate and depend on public disclosures, the consensus from cybersecurity analysts and government agencies such as the Australian Cyber Security Centre confirms a marked upward trajectory in both scope and financial impact. This is corroborated by IBM’s Cost of a Data Breach Report, which regularly identifies costs climbing globally year after year, underscoring that Australia’s figures align with international trends.
Crucially, there is consensus among security experts that there is no such thing as a totally impenetrable system. However, basic cyber hygiene – keeping software and hardware updated and patched – remains a frontline defence. As threat actors focus their efforts on unpatched vulnerabilities, obsolete systems become soft targets.
Chris Bright, Microsoft A/NZ Device Partner Sales Lead, voiced particular concern about the estimated three million commercial Windows Pro devices in the region that are ineligible for upgrade due to hardware restrictions. “Prompt action is critical to ensure continued protection, performance, and support,” Bright urges, warning that organisations are effectively playing a dangerous game of brinkmanship with their cyber resilience.
This sentiment is echoed elsewhere in the industry. Analysts repeatedly flag the risk that a last-minute rush to upgrade will lead to corners being cut, exposing further vulnerabilities and operational headaches. In many cases, a lack of proactive planning leaves organisations hamstrung when the day arrives.
Industry analysts from Gartner and Forrester highlight that post-EOS, simply running security solutions atop an unsupported OS does not absolve organisations from responsibility, nor does it satisfy minimum compliance requirements. The OAIC’s public guidance on notifiable data breaches repeatedly affirms the necessity of current support for operating systems as part of “reasonable steps.”
Notably, Windows 11 ships with new AI features that extend beyond marketing hype and into real, measurable productivity gains. Examples include improved voice recognition, smarter virtual desktops, and context-aware assistance applications, many of which depend on hardware-level AI acceleration unavailable in older machines. According to surveys, an average 50% efficiency increase has been observed in early-adopter enterprises, with 90% of users reporting higher satisfaction and productivity post-migration, although these numbers are typically drawn from sponsored studies or preliminary surveys and thus should be interpreted with informed skepticism.
A detailed study by Forrester found that the overall economic impact of Windows 11 Pro is significantly positive for organisations prepared to approach migration methodically, with gains stemming from improved operational efficiency, security posture, and end-user satisfaction.
Note: Some performance and productivity claims are based on aggregate or sponsored surveys and should be verified in real-world context.
The upside is that vendors and Microsoft channel partners have launched coordinated support efforts. In Australia and New Zealand, alliance programs with Dell, HP, Lenovo, Datacom, and Data3 are offering assessment services, device trade-in incentives, and deployment planning to ease the financial and logistical burden of hardware refresh cycles.
Proactive organisations are using this moment to modernise their IT fleets, standardise on secure, manageable platforms, and reduce the complexity that accrues from maintaining a long tail of legacy endpoints.
Conversely, proactive transition is arguably an investment in resilience, providing a platform that not only closes the most glaring security loopholes but also sets the stage for future growth, AI adoption, and seamless hybrid work.
By taking action now, organisations position themselves to ride the next wave of innovation rather than being left behind. The cost of inertia—combined with an aggressive cyberthreat environment and evolving compliance landscape—means that waiting until Windows 10’s EOS is not just a gamble, but a calculated risk that few modern businesses can afford.

The Mounting Risk: Cybersecurity in an AI-Enhanced Threat Landscape
The frequency and sophistication of cyberattacks have accelerated at an unprecedented rate in recent years. Cybercriminals now leverage advanced technologies, most notably artificial intelligence, to automate, personalise, and scale their attacks.

The End of Windows 10 Support: What It Really Means
With the Windows 10 end-of-support date looming, businesses dependent on this operating system face a set of escalating risks:- Data Breaches: When support ends, Microsoft will cease providing regular security patches and updates. This creates a fertile environment for attackers, as vulnerabilities discovered post-EOS will remain unaddressed. It is notable that by 2024, there were on average 20 to 25 major ransomware attacks occurring daily, many zeroing in on unsupported or poorly maintained systems. Sources like the 2024 Verizon Data Breach Investigations Report support this trend, demonstrating an explicit correlation between unsupported systems and successful ransomware infiltrations.
- Regulatory Non-Compliance: Many jurisdictions, including Australia, mandate prompt software updates and robust data protection measures. Organisations relying on unsupported software may quickly fall afoul of statutes such as the Australian Privacy Act, potentially triggering investigations and severe penalties from the Office of the Australian Information Commissioner (OAIC).
- Operational Downtime: Unsupported or compromised systems can lead to costly disruptions. Globally, the average cost for recovering from a ransomware event is calculated at US$4.54 million, a figure that encapsulates ransom payments, system downtime, legal repercussions, and intangible losses such as reputational damage.
- Stalled Innovation: Beyond security, organisations languishing on legacy platforms may find themselves unable to adopt emerging technologies or integrate critical new applications due to incompatibility, thus losing competitive edge.
A Reluctance to Act – And the Hidden Dangers Within
Analysis by Microsoft’s regional leaders, reinforced by usage statistics from independent research, suggests that as of early 2024, the overwhelming majority of commercial devices in Australia and New Zealand still run Windows 10, despite Windows 11’s growing market share. The reasons are multifaceted: inertia, hardware incompatibility (many Windows 10 machines do not meet Windows 11’s TPM 2.0 requirement), resource constraints, and the natural resistance to large-scale change.Chris Bright, Microsoft A/NZ Device Partner Sales Lead, voiced particular concern about the estimated three million commercial Windows Pro devices in the region that are ineligible for upgrade due to hardware restrictions. “Prompt action is critical to ensure continued protection, performance, and support,” Bright urges, warning that organisations are effectively playing a dangerous game of brinkmanship with their cyber resilience.
This sentiment is echoed elsewhere in the industry. Analysts repeatedly flag the risk that a last-minute rush to upgrade will lead to corners being cut, exposing further vulnerabilities and operational headaches. In many cases, a lack of proactive planning leaves organisations hamstrung when the day arrives.
Why Staying on Windows 10 Is Riskier Than You Think
The Security Gap Grows Wider
Microsoft claims Windows 11 Pro offers up to 40% more security features than its predecessor, a statement verified by independent technology reviewers. Key advancements include:- Integrated hardware-based isolation and encryption built around TPM 2.0 and Secure Boot
- Enhanced protections against phishing and credential theft
- Advanced ransomware detection and mitigation using AI-powered heuristics
- Improved Windows Hello biometrics and anti-spoofing capabilities
Compliance and Regulation: No Room for Error
The regulatory environment continues to tighten. In Australia, amendments to privacy legislation signal an ongoing trend toward tougher enforcement and higher penalties. In the case of a breach, organisations must now demonstrate they have taken “reasonable steps” to safeguard personal and sensitive data, with software updates being a minimum baseline for compliance.Industry analysts from Gartner and Forrester highlight that post-EOS, simply running security solutions atop an unsupported OS does not absolve organisations from responsibility, nor does it satisfy minimum compliance requirements. The OAIC’s public guidance on notifiable data breaches repeatedly affirms the necessity of current support for operating systems as part of “reasonable steps.”
Business Continuity and Innovation
Unsupported platforms not only invite additional risk—they also restrict the ability to innovate. As software vendors retire support for Windows 10, integration with emerging platforms, services, and productivity tools will break down. This “innovation drag” becomes a stealth risk: businesses slowly lose agility, struggle to deploy new AI-driven applications, and fall behind more nimble competitors.Notably, Windows 11 ships with new AI features that extend beyond marketing hype and into real, measurable productivity gains. Examples include improved voice recognition, smarter virtual desktops, and context-aware assistance applications, many of which depend on hardware-level AI acceleration unavailable in older machines. According to surveys, an average 50% efficiency increase has been observed in early-adopter enterprises, with 90% of users reporting higher satisfaction and productivity post-migration, although these numbers are typically drawn from sponsored studies or preliminary surveys and thus should be interpreted with informed skepticism.
The Financial and Strategic Case for Upgrading
Microsoft is keen to trumpet the economic benefits of Windows 11 Pro, often citing figures such as a 250% return on investment (ROI) over three years and noticeable reduction in maintenance costs. Third-party validation of these numbers varies, but there is consensus that indirect costs—such as reduced helpdesk tickets and less time spent on troubleshooting—can offset the capital outlay for new hardware and software licensing, especially when balanced against the steep costs of a single critical incident.A detailed study by Forrester found that the overall economic impact of Windows 11 Pro is significantly positive for organisations prepared to approach migration methodically, with gains stemming from improved operational efficiency, security posture, and end-user satisfaction.
| Benefit | Source | Windows 10 | Windows 11 Pro |
|---|---|---|---|
| Built-in ransomware mitigation | Microsoft/Gartner | Limited | Advanced (AI-driven) |
| Hardware-based isolation | Microsoft | No (optional) | Yes (default) |
| Endpoint management and analytics | Forrester | Standard | Enhanced, AI-integrated |
| Average user productivity increase | Independent survey | Baseline | Up to 50% (claims) |
| Regulatory compliance assurance | Regulatory agency | At risk post-2025 | Industry standard |
Hardware Hurdles: The Realities of Upgrading
A significant factor in delayed migration is hardware compatibility. Windows 11’s requirements—most notably TPM 2.0, Secure Boot, and specific CPU generation cutoffs—exclude a substantial proportion of legacy devices from eligibility. Analysis by IDC and similar research firms estimates that globally, tens of millions of enterprise devices cannot be upgraded in-place.The upside is that vendors and Microsoft channel partners have launched coordinated support efforts. In Australia and New Zealand, alliance programs with Dell, HP, Lenovo, Datacom, and Data3 are offering assessment services, device trade-in incentives, and deployment planning to ease the financial and logistical burden of hardware refresh cycles.
Proactive organisations are using this moment to modernise their IT fleets, standardise on secure, manageable platforms, and reduce the complexity that accrues from maintaining a long tail of legacy endpoints.
The Migration Journey: Strategies for Success
Transitioning to Windows 11 represents a major operational project for many businesses, but industry leaders emphasize that the risks of delay far outweigh the headaches of migration. Best practice recommendations from Microsoft and independent IT consultants include:- Initiate Early Assessment: Catalogue and evaluate existing hardware against Windows 11 compatibility, identifying candidates for upgrade versus replacement.
- Plan for Contingency: Develop a timeline that allows for thorough testing of business-critical applications in the new environment, mitigating the risk of surprise incompatibilities.
- Leverage Vendor Expertise: Engage with official Microsoft partners to receive tailored guidance, project management, and potentially financial incentives for bulk device upgrades.
- Communicate Change: Work with internal stakeholders early to address and manage change resistance, ensuring all employees understand the security, compliance, and productivity benefits of the new platform.
- Iterative Deployment: Avoid “big bang” migration strategies in favour of phased rollouts that limit disruption and allow for incremental troubleshooting.
Critical Analysis: Strengths and Caveats in the Argument for Migration
Strengths
- Security by Design: Windows 11’s hardware-software integration and focus on Zero Trust architecture address many of the failings of legacy platforms. The continual updating of security features—ranging from vulnerability mitigations to advanced threat detection—represent a tangible leap forward.
- Alignment With Regulatory Best Practice: Modern operating systems are foundational for achieving and maintaining compliance with data protection and privacy mandates worldwide.
- Enhanced Productivity: For organisations able to fully leverage Windows 11’s new features and AI capabilities, clear improvements in workflow and operational tempo are documented.
Potential Risks and Limitations
- Cost and Resource Burden: For organisations with extensive legacy hardware, the capital expense of replacing non-compliant devices is significant. There may also be hidden costs related to new application licensing, retraining staff, and the risk of transitional downtime.
- Incompatibility and Custom Solutions: Enterprises reliant on custom-built software or niche hardware integrations may discover post-upgrade complications, potentially necessitating substantial redevelopment or new supplier engagements.
- Hype Versus Practicality: Survey claims of massive efficiency or satisfaction gains may not be universally replicable. Early adopters are often the most motivated and technologically sophisticated, so broader rollouts could see more mixed results.
- Environmental Concerns: A mass hardware refresh carries environmental implications, from e-waste to the carbon footprint of new device production. Savvy organisations will look for recycling or device trade-in programs to offset this impact.
Looking Forward: The Strategic Imperative
Resistance to technology transitions is as old as IT itself. Yet, history shows that end-of-life for well-loved operating systems is a key inflection point: the organisations that procrastinate on upgrades pay a steep price in risk exposure, compliance lapses, and missed productivity.Conversely, proactive transition is arguably an investment in resilience, providing a platform that not only closes the most glaring security loopholes but also sets the stage for future growth, AI adoption, and seamless hybrid work.
By taking action now, organisations position themselves to ride the next wave of innovation rather than being left behind. The cost of inertia—combined with an aggressive cyberthreat environment and evolving compliance landscape—means that waiting until Windows 10’s EOS is not just a gamble, but a calculated risk that few modern businesses can afford.
Conclusion
The end-of-support deadline for Windows 10 is approaching inexorably, and the risks of failing to migrate—spanning security, compliance, operational, and reputational domains—are too great to ignore. While upgrading can be complex and resource-intensive, the argument for transitioning to Windows 11 is both compelling and urgent. Supported by tangible evidence and the collective experience of industry leaders, the move is not merely a technical necessity, but a cornerstone of future-proofing the modern digital organisation. The time to act is now, before the window of opportunity closes and risk becomes reality.Source: cio.com Not yet moving to Windows 11? You’re putting your organisation at risk
