The makers of an AI model claim it can take control of a computer and complete tasks such as completing forms. The latest version of "Claude" takes a screenshot and counts pixels to figure out how far to move the cursor. Anthropic, which made ... Claude, say this is the first time a publicly released AI model has the capability of "computer use". It defines this as "looking at a screen, moving a cursor, clicking buttons, and typing text. The goal is to allow the model to carry out tasks which go beyond simply generating text or images in line with a user's instructions. Instead, it could actually ... (view more)

Windows users will soon be able to access files on their Android phone or tablet without a USB cable. The feature is already available in test editions of Windows 11. The feature, first reported back in June, has now arrived for members of the ... Windows Insider Program, which gives early access to in-development and test features. They will also need to install the "Cross device experience host" tool from the Microsoft store. Windows does already offer some wireless connectivity with Android phones such as using it as a webcam or getting on-screen notifications from the phone replicated on the ... (view more)

An unprotected Windows XP machine lasted just 10 minutes online before being infected. It was an extreme and arguably unrealistic experiment, but does show just how prevalent online threats are. YouTuber Eric Parker carried out the test with a ... virtual machine running Windows XP. A virtual machine is a machine that lives inside of another machine, which makes it appear as if the virtual machine is a separate, physical computer. It's often used by people running two operating systems on the same computer. In fact, this website runs as a virtual machine. At any rate: it's no secret that running ... (view more)

A new form of computer memory has won an award for innovation. UltraRAM combines the performance of ordinary computer memory with the long-term storage of flash. Most memory in a computer is DRAM (dynamic random access memory). This holds data that ... the computer processor is most likely to need to access imminently. It's a little like having paper documents on a desktop rather than in a filing cabinet: the cabinet has much more room, but it takes some time to walk to the cabinet to get the information, versus having it right on the desktop. One of the key drawbacks of DRAM is that it stores ... (view more)

Software engineers have been debating whether today's operating systems are slower to respond than their predecessors. It led one site to experiment with running Windows XP on a new computer. After some hassles of getting it going, it turned out ... that XP felt extremely fast to use, albeit with a serious risk of malware infection. The debate started when Julio Merino put together "real-time videos" of an old machine running Windows NT 3.51 (a business version roughly equivalent to Windows 95 for consumers) and a modern machine running Windows 11. (Those of us of a certain age may have to ... (view more)

Microsoft has warned users that a "wipe clean" option in Windows won't remove all files thanks to an ongoing bug. It's mainly a practical problem for anyone planning to sell or give away a computer with hopes of removing all personal data prior. The ... problem is specifically with the reset option in Windows that lets users "reinstall" the system without needing to download files or create a USB or DVD boot disc. This option always removes all installed applications, but users have a choice whether or not to also remove files such as documents. When they choose "remove everything", ... (view more)

Windows 11 will soon give users extra controls to stop applications hogging resources. The Task Manager change will help users balance performance and control. The new Efficiency Mode works in a similar way to power-saving mode on some PCs and ... mobile devices, though in this case the emphasis is on the processor. At the moment, users have several options for dealing with "greedy" applications but they all involve compromises. One option is to put the entire computer into a "Best Power Efficiency" option through the power mode settings. The problem is that this affects all ... (view more)

A new form of computer memory could cut costs and storage space. "UltraRAM" would combine storage and memory on a single unit. Historically computers have always had to use separate units for memory (which is only needed temporarily) and file ... storage (which needs to be available until intentionally deleted or altered). As a rough analogy, file storage is like a filing cabinet, while memory is more like an in-tray, holding information to hand for quick access during the current task. Today many machines use flash memory for both RAM (the main memory on a PC) and solid state drives (a quicker ... (view more)

Mozilla has announced a rethink of a key technology used to make web users safer. The latest update to its Firefox browser improves the "sandboxing" approach. One of the biggest security concerns with web browsers is the way a single application ... (the browser) can handle data from multiple sites open in different tabs. It creates the risk that a compromised site could access data from another site; for example, one tab might display or transmit emails, login details or financial information. The way browsers tackle this risk is called sandboxing. That means telling operating systems such as ... (view more)
