If you decide to keep your files, you’ll be presented with a list of apps that will be affected and then asked to confirm the reset. The other two options involve further questions. If you have multiple drives on your machine, you’ll need to decide whether to remove the files from all drives, or just the drive where Windows is installed. For a full reset, choose the latter option.You’ll then be given the option to clean your drives as well as remove files. If you're just refreshing your own machine, the first option is much quicker. If you’re planning to pass on your laptop, it will be worth cleaning the drive. This will take longer but will make it much harder for anyone to recover your removed files. Finally, you’ll be given a breakdown of what will happen to your laptop if you restore it to factory settings. If you’re happy with this, you can click Restore and the process will begin.

Now it’s time to sit back, relax and whip up a brew. Depending on your choices, and the speed of your system, this can take up to an hour. You’ll know it’s finished when you’re prompted to agree to the licence agreement. The world of wireless routers is changing for the better. After years of being stuck with the 802.11n standard, the faster 802.11ac has finally taken hold in the wireless router market and, crucially, among manufacturers of tablets, laptops and smartphones. But how do you choose the best wireless router for your needs? Is the best wireless router for ADSL and fibre connections the same as the best wireless router for cable customers?

Well, wonder no longer - our guide to the best wireless routers of 2016 is here to help you decide. Picking the best wireless router depends on a number of factors, the most important of which is the type of internet connection you have. This will also dictate whether you can ditch your ISP-provided model altogether, or whether you’ll have to use it side by side with the new one. ADSL customers have the widest choice, since ADSL is the most widely supported connection among router manufacturers. As long as you have access to your ISP login details, you should be able to swap out one box for another – cutting down on cable clutter and freeing up a power socket.Not all third-party routers have the necessary VDSL modems for fibre broadband connections. If you buy a router that doesn’t, you’ll need to use your ISP-supplied modem alongside it. However, VDSL support is gradually growing, so with the right router you’ll be able to completely replace your existing kit.

Cable connections are the least broadly supported by third-party routers, which means you’ll almost certainly need to use your existing box in tandem with any new model you buy.Without exception, all the routers in our list support 802.11ac. It's faster than 802.11n and the type of router you should be looking out for when upgrading your wireless. Note, though, that the numbers manufacturers use to sell their compatible routers can be a little misleading. An AC1900 router doesn’t actually deliver a link rate of 1,900Mbits/sec; that number is, in fact, the sum of the maximum rated speeds over 802.11n and 802.11ac combined.For cable connections you’ll need to use your existing box in tandem with any router you buy These numbers are also related to the number of spatial streams and the channel width your devices are capable of transmitting and receiving. A 1x1 configuration means one antenna supporting one data stream; 2x2 is two antennas supporting two data streams. You can guess 3x3 and 4x4.

In practice, a laptop with a 2x2 setup would only be able to connect to an AC1900 connection at 867Mbits/sec – you’d need a 3x3-stream device to get the full 1,300Mbits/sec. Support for multiple antennae and data streams is known as multiple-input, multiple-output technology and given the shorthand MIMO.Even in ideal circumstances, you won’t see file-transfer rates reach your router’s theoretical maximum Wi-Fi speeds, thanks to network protocols, bottlenecks and other overheads. However, with the right kit, you should be able to approach performance similar to that of a wired Gigabit Ethernet connection. It’s worth noting that using multiple devices at the same time will split the available bandwidth, unless you use a Wave 2 router with Multi-User MIMO (MU-MIMO).Remember, also, that upgrading your router won’t guarantee the fastest possible wireless speeds: you’ll also need to invest in additional network kit for your PC or laptop if they don’t support 802.11ac.

That said, even if you don’t own compatible kit, an 802.11ac router can still improve the reliability of your 802.11n network. Implicit or universal beamforming can eliminate dead spots and speed up your connection in areas that were previously slow.Immediately below, you’ll find our pick of the very best four wireless routers on the market, and if you read on to the following page you’ll also find reviews of all current routers supplied by the four major UK ISPs and instructions on how to replace them with a better model, should you wish to do so.The Netgear Nighthawk X4S is not only one of the fastest wireless routers we’ve ever seen, it’s also future-proof and packed with features. What’s more it covers all the connectivity bases, whether you’re a fibre, ADSL or cable internet customer. The only thing it doesn’t do is make the tea.

Synology brings its expertise in software design to the world of routers and the result is an absolute triumph. Not only is it power and easy to use, but performance is exceptional and the price nothing short of stunning. Read our full Synology RT1900ac review here It’s a bit of a hulking beast, and the price is high, but Asus’ range-topping router performed brilliantly in our tests. Its tri-band wireless lets multiple users get maximum network performance, and although its USB speed isn’t the best, it’s a good buy for speed freaks. Read our Asus RT-AC3200 review here D-Link DIR-890L review Another tri-band device, D-Link’s Ferrari-styled DIR-890L is the Enzo of the wireless router world. It lets multiple devices connect and download at top speed, and D-Link has overhauled its software to great effect. It's a mean, red Wi-Fi machine. We don't normally include ISP-supplied device in our best router roundups, but BT's latest Smart Hub is good enough to live with the best. It has a total of seven internal antennae, enabling 4x4 MIMO 802.11ac wireless in the 5GHz band and 3x3 MIMO over 2.4GHz.

That means a top theoretical speed of 1,700Mbits/sec and 450Mbits/sec respectively – a big improvement over the 1,300Mbits/sec and 300Mbits/sec maximum of the previous Home Hub. Most importantly, the latest BT Wi-Fi performs brilliantly, delivering great speed and stability in parts of my home that many routers struggle to deliver any kind of connection to.As with most ISP routers, it isn't replete with features, but new and existing BT customers owe it to themselves to consider upgrading to the latest BT router. It's a cracker. Read the full BT Smart Hub review hereTim Peake is the first official British astronaut to head into orbit to the International Space Station (ISS), but if you want a closer look at the stars, you need head no further than Leicester. It’s home to the National Space Centre, including the UK’s largest planetarium, a 3D spaceflight simulator and six galleries of hands-on displays.

The centrepiece of the centre is the “iconic” Rocket Tower, according to marketing administrator Rebeca Leggat. The 42-metre, semitransparent structure, covered in high-tech “pillows”, was designed to house a pair of famous rockets: the Blue Streak (which was used to launch satellites) and the Thor-Able (an American system used at Cape Canaveral). The tower is also home to the Gagarin Experience, which lets you sit inside the space capsule that took the Russian cosmonaut into orbit; an Apollo lunar lander; a real chunk of moon rock; and an Edwardian cinema playing the first ever sci-fi film. And that’s just the Rocket Tower. Leggat said a “key piece would be the Sir Patrick Moore Planetarium,” which features a new show called We Are Stars, tracking the evolution of the universe. If you’re not spaced out after the tower and planetarium, you can make your way through the six galleries, walk through a mock-up of the ISS, and get a close-up view of a Soyuz capsule. Younger visitors hoping to follow Tim Peake to the ISS should head to Tranquillity Base, where they can try being a trainee astronaut, through the Spaceflight Induction Module ride and a host of interactive games.

These exhibits are targeted at older children – and their science-loving parents or guardians – but there are also activities to hold the attention of smaller space explorers. “Primarily, the National Space Centre is aimed at children five and up,” said Leggat. “However, we have now incorporated more into our galleries for the little ones, including dress-up costumes, a new ‘tinytarium’ show and dedicated ‘Small Space Toddler Days’.”The National Space Centre is open Tuesday to Sunday. Tickets cost £13 for adults and £11 for children, with those under five admitted for free. If you buy online, you can nab an annual pass for the price of a day ticket.

I can’t find figures for exactly how many USB flash drives are sold each year, but given I can see five without leaving my desk, I’m going to go with a ballpark estimate of “a lot”. If you have more than you know what to do with (or more than you have USB ports to put them in), two charities would love for you to consider sending them their way. They are Forum 280 and the Human Rights Foundation, which have launched Flash Drives for Freedom. What do they want to do with your old USB sticks? Well, they want to wipe them clean and fill them up with all kinds of media, including Hollywood films, South Korean TV shows and Korean Wikipedia.They then want to smuggle them into North Korea at great personal risk. Distributing this kind of content is very, very illegal in the secretive state, where government censorship is just a part of life.
