Beyond the refresh: Your cyber strategy must include AI PCs | Computer Weekly

It’s easy to view PC refreshes as simply cosmetic. Businesses get new designs, faster processors and maybe a thinner chassis. But while these enhancements are certainly welcome, the real significance of a device refresh strategy runs much deeper. By investing into modern AI-powered PCs, businesses are building a more secure, productive, and resilient future. As we mark Cybersecurity Awareness Month and Microsoft Windows 10 reaches end-of-support, now is the perfect time to explore how a modern PC strategy plays an important role in securing organisations.
While the shift to hybrid work has seen employees enjoy greater flexibility, IT teams are also facing an expanded attack surface. Endpoints are no longer safely behind the corporate firewall. Instead, they connect from home networks, public Wi-Fi and everywhere in between, making them prime targets for cyber criminals. As businesses adjust and advance remote working policies, ensuring the security of all devices is paramount.
From phishing to fraudulent websites, cybercrime is more prevalent than ever, with the latest UK Government Cyber Security Breaches Survey revealing 43% of businesses have experienced a cyber security breach or attack in the last 12 months. Our recent UK research with Intel found that for nearly half (46%) of IT decision-makers, news of high-profile cyber breaches is the primary motivator to refresh their PC fleet – more so than an operating system deadline itself. As threats grow more sophisticated and costly, organisations must rethink all IT decisions through a security-first lens. This is where a strategic approach to the PC lifecycle comes into play, transforming a routine refresh into a critical security update.
The hidden risks of an ageing fleet
Holding onto older devices for too long might seem like a cost-saving measure, but it often creates hidden risks. It potentially leaves millions exposed to significant cyber threats, as they will no longer receive crucial security updates, making them vulnerable to new viruses and cyber attacks.
Crucially, these outdated devices don’t have integrated neural processing units (NPUs) to run AI workloads securely and efficiently on the device itself. By processing sensitive data locally, AI PCs shrink the attack surface, improve data control in line with regulations like GDPR and build resilience against threats that target cloud-based applications.
Furthermore, Windows 11 has been designed with a security-first mindset, requiring hardware with features like a Trusted Platform Module (TPM) 2.0. This chip provides hardware-based security functions, such as creating and storing cryptographic keys, that are far more secure than software-only solutions. Attempting to run modern software on legacy hardware not only hampers performance but also leaves critical security gaps. Without the underlying hardware support, organisations can’t fully use the advanced protections that new operating systems offer, leaving them vulnerable to cyber attacks.
The rise of on-device AI and small language models
The conversation around AI is rapidly shifting from massive, cloud-exclusive models to a more decentralised approach. The rise of small language models (SLMs) trained for specific tasks makes it possible to run powerful AI directly on an endpoint. This allows organisations to deploy AI for sensitive operations like financial analysis, code development, or reviewing confidential documents without that data ever leaving the device.
This move toward on-device AI is not a distant future; it is happening now. However, it is entirely dependent on having the right hardware. AI PCs with dedicated NPUs are purpose-built to handle these SLMs, supporting a new class of secure, private and low-latency AI applications. For businesses, this means the PC refresh is no longer just about keeping up – it’s about preparing for a fundamental change in how enterprise AI will be deployed.
How modern PCs help build a secure foundation
Threat actors are persistent, but a modern AI PC provides a crucial line of defence in a zero-trust world. The security of on-device AI processing is built upon a foundation of hardware and firmware-level security features that operate below the operating system. This provides a more resilient defense against attacks that aim to compromise software protection.
In day-to-day use, features like BIOS and firmware verification ensure the device is tamper-free, while secure storage for credentials protects against identity attacks – one of the biggest challenges for organisations today. Before even reaching an employee, modern PCs from trusted vendors can include optional supply chain security measures. For example, a digital certificate created in the factory that allows organisations to verify component integrity and safeguard against tampering. This hardware-level trust is what makes on-device AI a viable and secure strategy.
A refresh strategy for a resilient future
Viewing PC refresh as part of an organisation’s security strategy helps build a more resilient and productive enterprise. It’s an opportunity to move beyond a tactical upgrade and adopt a security-first hardware strategy that works in the AI era. This approach delivers tangible benefits: it reduces the burden on IT teams, improves employee experience, and most importantly, strengthens an organisation’s overall security posture against an ever-evolving threat landscape. Our research shows that refreshing to modern devices running Windows 11 can result in up to 62% fewer security incidents, a testament to the power of an integrated, security-first hardware strategy.
Now is the time business leaders look at their PC fleet through a new lens. In an age where AI is reshaping every industry, your employees are the first line of defence and equipping them with the right tools is imperative. An AI PC fleet is not just a collection of faster devices; it is a foundational component of a robust, future-proof security strategy.

E-cargo bikes can replace car trips and reshape family travel

Electric cargo (e-cargo) bikes can replace many car journeys, from school runs to shopping trips and family outings, according to new research. They also have the potential to shift how families and communities perceive cycling, making it a more practical and inclusive everyday option.
The research shows that e-cargo bikes can do many of the jobs we rely on cars for, while also bringing the social benefits of cycling. The research is also helping to normalize cycling and change views in places where cycling doesn’t always have a positive image.
Researchers analyzed the experiences of 49 households who trialed e-cargo bikes as part of a loan scheme in British suburbs. The study included researchers from Eindhoven University of Technology, University of Brighton and University of Leeds University of Oxford.
New social norms
Published in the journal Geoforum, the study found that e-cargo bikes are not only practical alternatives to cars for some but also foster new social norms and cultural identities around family, community and sustainable travel.
They showed that e-cargo bikes offer a hybrid experience for users, allowing interaction between riders and passengers, somewhat vehicle-like, while still connecting users to their local surroundings.
Key findings of the study include the following:
- Everyday practicality: Study participants used e-cargo bikes for lots of reasons including school runs, food shopping and commuting, trips often seen as only possible by car. More than a technical trait, this everyday practicality encourages a cultural shift, normalizing cycling as utility activity beyond leisure or sport.
- Family mobility: Unlike conventional cycling by individuals, e-cargo bikes often involved carrying children or passengers, creating a sense of shared family travel. It enabled interactions between rider and passengers, not hugely dissimilar to traveling by car.
- Community connection: Riders reported feeling more connected to local communities compared to car use, describing e-cargo cycling as “part of the neighborhood.”
- Novel and unconventional: While most interactions were positive, some riders experienced feelings of being unconventional or out-of-place, linked to concerns over child safety.
More than a novelty
Clara Glachant of the Eindhoven University of Technology and lead author of the study, said, “This trial shows e-cargo bikes are more than a novelty. They can fit into everyday family life. Our findings suggest that e-cargo cycling may help cultivate a cycling culture both at the household level and the community level. They may reshape ideas of who belongs on the road, who is entitled to space. This could help to reduce anti-cyclist sentiment which would help active travel contribute more to sustainable transport.
“It’s also about culture: people’s habits, identities and perceptions of transport. Our research shows e-cargo bikes can help reshape these, challenging what psychologist Ian Walker has coined ‘motonormativity,’ a concept that describes society’s unconscious acceptance of car dominance and making cycling feel like a more normal, mainstream choice.”
The ELEVATE project
Professor Ian Philips of the University of Leeds, who leads the ELEctric Vehicles for Active and Digital TravEl (ELEVATE) project, said, “The ELEVATE project is about understanding who might benefit from using e-cargo bikes and other e-micromobility in what circumstances and to understand if that has a positive effect on carbon emissions, health and other important aspects of people’s lives.
“Clara’s work on the project helps us see more about how e-cargo bikes fit into daily life in terms of culture, perceptions and identities around active travel.”
Combining innovative technology
Professor Charlotte Deane, Executive Chair of Engineering and Physical Sciences Research Council (EPSRC), said, “This research shows that transforming transport sustainably means combining innovative technology with an understanding of people’s everyday choices and behaviors.
“New designs in e-cargo bikes are making them more practical and accessible, helping families replace short car trips. They can cut congestion and emissions while opening up cycling to more women and children. Through projects like ELEVATE, EPSRC is supporting innovations that have the potential to change how we travel and create healthier, more connected communities.”
Individual perceptions
The research highlights that shifting towards low-carbon transport isn’t just about infrastructure or technology but also about how people perceive themselves and cultural perceptions associated with transport modes.
The National Travel Survey data published in 2024, shows while 81% of journeys under one mile in length in 2023 were made by foot, 17% were made by car or van.
For journeys between one and five miles, 69% were made by car or van, compared to 19% by foot and 6% by bus. Between five and 10 miles, 83% of journeys were made by car or van.
More connected communities
Encouraging e-cargo bike use could help reduce urban congestion, lower emissions and create healthier, more connected communities.
The researchers add that as cycle commuting in the UK is male-dominated, e-cargo bikes may help include more women and children in utility cycling.

The Shutdown Is Pushing Air Safety Workers to the Limit

“We will never compromise on safety. When staffing constraints arise, the FAA will slow down air traffic at impacted airports to ensure operations remain safe,” FAA spokesperson Hannah Walden tells WIRED, adding that Transportation secretary Sean Duffy “said that air traffic controllers who report to work will be paid. Regarding reductions in force (RIFs), DOT has been clear for months: safety critical positions—including air traffic controllers—have and will continue to be exempt from any RIFs.”
In a written statement, a spokesperson for the TSA said of employees working without pay: “It’s unfortunate they have been put in this position due to political gamesmanship. Our hope is that Democrats will soon recognize the importance of opening the government.”
On Thursday, Duffy suggested on Fox Business News that controllers and other workers who don’t come to work during the shutdown would be fired. “If we have a continual small subset of controllers that don’t show up to work, and they’re the problem children … if we have some on our staff that aren’t dedicated like we need, we’re going to let them go,” said Duffy.
One air traffic controller described this week’s working conditions as “pretty much the same” but with “an undercurrent of fear that the dipshits in charge will use this as an excuse to decertify our union and take away all bargaining rights.”
Air traffic workers know that accusations of coordinated activity and sick-outs, or informal labor actions that could violate long-standing bargaining agreements with the government, are especially perilous right now, as federal officials threaten the status of public sector unions. The Trump administration suddenly ended TSA workers’ collective bargaining agreement in March, before a court preliminarily halted the move in June. Workers worry that taking an absence, even when it’s needed, could have long-term consequences for their union—and therefore, their working conditions.
The National Air Traffic Controllers Association did not respond to WIRED’s request for comment. But a pop-up on the public union’s website notes that it “does not endorse, support, or condone any federal employees participating in or endorsing a coordinated activity that negatively affects the capacity” of the National Airspace System.
Jones, the TSA agent and union leader, says his group won’t organize sick-outs. But employees may have to call out if the lack of pay means “they don’t have the means to commute into work,” he says.
“We are sick and tired of being political pawns for Washington,” adds Jones.
