Fake online reviews could be made illegal

Authorities are trying to clean up fake reviews on websites, to stop undeserving companies getting a good reputation online.

Our guide to 5G

We’ve only recently started using 4G but the mobile industry is already preparing for the next big speed boost, as David Crookes explains

What is 5G?

Turn your old laptop into a super-speedy Chromebook

If your old PC can’t handle Windows 10, install Chrome OS instead. Wayne Williams guides you through the process

Buying a laptop used to involve a straight choice between two operating systems – Windows or Mac OS X. But now there’s Google’s Chrome OS, which offers a low-cost third option. Chromebooks running the cloud-based operating system have become very popular and it’s easy to see why. They are affordable because as long as you’re happy to carry out most of your work on the web and in your browser, they don’t require much expensive processing power.

The same principle can be applied to an old PC, so although it may not be able to run the latest version of Windows, your old computer may still have more than enough power to run the Chrome operating system. CloudReady (www.neverware.com) brings the Chromebook experience to your PC, and can either replace your existing Windows installation or run alongside it. The OS is aimed commercially at schools but is being given away free to home users.
