Unless you're a fan of using a computer that looks and feels the same as everyone else, you probably want to spend some time tweaking Windows so it works the way you want it to. Broadly speaking, tweaks fall into three categories -- those that change appearance, those that boost performance, and those that change the way things work.

Windows 10 does -- through Settings and the Control Panel -- afford you a decent degree of control over how the operating system looks and works, but if you want to get serious about things you have two options: head into the registry, or turn to a dedicated tweaking and customization tool. Now there are endless apps to help make life easier, so here's a roundup of the best Windows 10 tweaking and customization tools.

For the past three years, the Raspberry Pi Foundation has released new products around its birthday (28 February). It didn’t this year due to snow and other reasons, but a fortnight later -- on Pi Day -- it’s time for the wraps to come off the latest Raspberry Pi.

The Raspberry Pi 3 Model B+ (Raspberry Pi 3B+ for short) is the successor to the Raspberry Pi 3 Model B, and improves on that device in a number of ways, while keeping the same low price ($35).

YouTube has faced criticism not only for allowing conspiracy videos to appear on the site, but also how it has dealt with them. The latest move by Google in this area will see information from Wikipedia and other websites displayed alongside such videos in the interests of balance.

Google says that the aim of the new "information cues" is to combat conspiracy theory videos it hosts, as well as trying to combat hoaxes.

Google has announced that advertisements for cryptocurrencies will be banned from its platform starting in June. The ban not only covers currencies such as Bitcoin and Ethereum, but also related products such as initial coin offerings, cryptocurreny exchanges and digital wallets.

The announcement came as Google is relying on new technology to detect and remove ads that violate policies. The company says it removed over 3.2 billion ads in 2017, and while it does not give a precise reason for the cryptocurrency ad ban, it says it is part of "improving the ads experience across the web."

The next big feature update of Windows 10 -- widely expected to be called the Spring Creators Update -- is due out next month. Microsoft is hard at work putting the finishing touches to it, but still has time to introduce some new additions.

In Build 17120, Microsoft has added some improvements to the Windows Defender Application Guard (WDAG), its virtualization-based security technology which helps to protect enterprises from advanced attacks that can infiltrate networks and devices via the Internet.

By its very nature, searches on Google Images are very visual things -- but that's not to say they couldn't be enhanced with some non-pictorial content. And that's exactly what Google has done, adding captions to image search results to make them more useful.

The aim is to provide greater context about results, giving users the chance to judge the quality of the image, and to perhaps determine whether the host site will have other useful images.

Researchers at threat prevention specialist Preempt have discovered a flaw in Credential Security Support Provider protocol (CredSSP), which is used by Remote Desktop and WinRM in their authentication processes.

An attacker with man-in-the-middle control over the session could use this to gain the ability to remotely run code on the compromised server masquerading as a legitimate user.

Today, the WONDERBOOM gets a makeover thanks to the all-new "Freestyle Collection." The internals remain the same (meaning it will still sound wonderful), but the outward design gets a fresh coat of paint with five new styles.

Off-the-shelf smart devices that include baby monitors, home security cameras, doorbells, and thermostats can be easily hacked according researchers at Israel's Ben-Gurion University of the Negev (BGU).

As part of their ongoing research into detecting vulnerabilities in devices and networks expanding in the smart home and Internet of Things (IoT), the BGU researchers disassembled and reverse engineered many common devices and quickly uncovered serious security issues.

Christine Lagarde, the head of the International Monetary Fund (IMF), has said that the blockchain technology behind cryptocurrencies could also be used to regulate them. She suggests that the IMF "fight fire with fire" in trying to address the "dark side of the crypto world."

While acknowledging the potential for the technology behind crypto-assets as being massively empowering -- particularly as a way to provide low-cost payment methods in poorer countries -- she says that cryptocurrencies also need regulation to avoid problems such as money laundering and funding terrorism.

This year’s Mobile World Congress was one of the best I’ve attended. While there was a lot of hype around the launch of Samsung’s Galaxy S9 , which looks pretty great, overall there was less of a focus on specific models and operating systems and more attention being paid to the new technologies that are solving customers’ problems, such as artificial intelligence (AI) and the Internet of Things (IoT). There was also a lot of discussion about how we secure, manage and control these technologies and how to comply with new and upcoming regulations, such as the General Data Protection Regulation (GDPR).

Here are my main takeaways from this year’s show:
