Sony Xperia M4 Aqua

An impressive smartphone at a reasonable price

There are a lot of amazing smartphones around these days, but some specifications look too good to be true. Well, here’s a new model with a slim metal case and a glass rear, high-resolution cameras, a big screen and one of the latest lightning-quick processor chips, yet costs just over £210 to buy outright. It’s even waterproof. Surely some mistake?

Vodafone Smart Ultra 6

High-performance budget phone

Over the page, we review the Sony Xperia M4, a very attractive phone for £210. The Smart Ultra 6 offers similar features for only £125, or £17 a month on contract with Vodafone (its exclusive vendor). It has the same fast processor as Sony’s phone, the same Android 5.0.2 software (Lollipop), and a bigger screen with 1080p Full HD resolution. And its rear camera, with the same 13-megapixel rating, takes nicer pictures.

Windows Task Manager Fast Fixes

Task Manager won’t launch

If you see an error message when launching Task Manager, it could mean that a system file is corrupted. System File Checker, a tool included with Windows, can fix this. Click Start, type cmd into the search bar (or straight into the Windows 8/8.1 Start screen), then right-click cmd (or Command Prompt in Windows 8/8.1) and choose ‘Run as administrator’. Next, in the Command window, type sfc /scannow, then press Enter and wait - it can take many minutes for the process to complete. Restart your PC, then try launching Task Manager.

If it still doesn’t work, a malware infection might be the problem. Make sure your security software is up to date, then perform a full scan.

Fix problems Microsoft won't

Still can't get your Desktop shortcuts to work? You're not alone, Barry Collins shows you how to solve problems Microsoft abandoned

With Windows 10 now the centre of attention, there’s one thing you can guarantee: Microsoft simply won’t be bothering to deliver anything but security updates for its predecessors, including Windows 7 and 8.1. In fact, it’s already withdrawn mainstream support for Windows 7 and earlier versions, and for pre-2010 versions of Office. Windows 10 is Microsoft’s sole focus now.

Here, we look at six common problems that Microsoft has left you to work out for yourself, and show you how to resolve them. Microsoft may have effectively abandoned the tools involved, but there’s no reason why you should have to give up on them too.

Canon Pixma MG6650

The only big black box you need

We go on about how our phones do everything that cameras, libraries and record players used to do, but don’t overlook the humble printer/scanner. It does everything phones don’t, converting printed paper into digital files and vice versa. Canon’s range has been a favourite of ours for some time, and this latest all-in-one maintains those high standards. The only thing it misses is faxing, which is obsolete for most of us.
