Windows 8 has many interesting new features, but the most important has to be the Store.
It's now easy to enhance your PC with a host of powerful apps - games, multimedia, tools, productivity and more - and these can then automatically be installed on all your other Windows 8 systems in a click or two.
You'll have to find them first, of course, which is something of a challenge, since the Windows Store now has thousands of apps competing for your attention.
But don't worry, we've been scouring the latest releases for the hidden gems, so if you'd like to save time and jump straight to the Store highlights then read on for our guide to the best Windows 8 apps currently available.

1. Metro Commander

One immediate advantage of the Store is it makes it very easy for developers to plug whatever gaps Microsoft might leave. So don't waste time wondering why Microsoft hasn't provided a file manager for the Start Screen, for instance - just install Metro Commander, instead.
The program provides a dual-pane interface on your files and folders, provides easy access to all the usual core functions - View, Rename, Copy, More, New Folder, New File and more - and offers integrated SkyDrive support, too.
Explorer remains far more powerful, of course, but if you need something simple and more touch-friendly, then Metro Commander should do the job.

2. musiXmatch Lyrics

Another advantage of the Store is it means PC software isn't isolated any more, somehow apart from your other devices. If you use the musiXmatch Lyrics app on your iPhone, iPad or Android device, for instance, then good news: it's now free to use on your Windows 8 system, too.
If you're new to musiXmatch, the app makes it easy to locate the lyrics for just about anything in your music collection. And we really do mean anything - the database now holds lyrics for around 6 million songs.
But if you're just feeling bored, you can alternatively browse the latest US and UK hits, listen to them, and watch the videos via YouTube.

3. Reversi Free

This fun version of the classic strategy game Othello is simple, straightforward and easy to use, yet still has more than enough power to keep you entertained for many hours.
And so there are three difficulty levels, for instance. You can go first, or second. And while the AI won't be too challenging if you're skilled at Reversi, if you get tired of the computer then there's an option to engage a human opponent, instead.
All this is presented in an appealing interface, nicely designed to look as though it's pencil-drawn. And this even extends to the sound of a pencil shading in pieces as they change colour (surprisingly, we didn't find this annoying, although if you do then you can turn it off). No bells and whistles, then - just the gaming basics done very well indeed, and that's fine with us.

4. Norton Satellite

15 best Windows 8 apps
Easy integration with online services such as Facebook is a plus point for Windows 8 - but you need to keep an eye on your security. And the free Norton Satellite can help.
The program uses apps to scan your Facebook links and Dropbox files, for instance, alerting you to threats before they have a chance to infect you. And if your worries lie elsewhere, then Satellite can scan particular files or folders on demand.
You don't get real-time protection for your whole system here, and so Satellite is no substitute for a full-strength antivirus package. It's simple, lightweight and easy to use, though, and will add a welcome extra layer of security to any Windows 8 system.

5. TuneIn Radio

15 best Windows 8 apps
Internet radio has always been a great way to keep yourself entertained, and TuneIn Radio shows off the technology with real style.
The app's huge database (more than 70,000 stations) means you're sure to find something you like, for instance. You can browse by music, sport, news, comedy, chat, language, country, or even just find a local station (assuming you've enabled the app to access to your location).
The program can also maintain a list of your favourite stations, for easy access later. Or you can even pin some to your Start Screen, so you can begin listening at any time with a click.

6. Fractal Photographer

If you've not come across the Mandelbrot Set before, then Fractal Photographer makes an excellent first guide, slowly revealing the fascinating infinity of gorgeous fractal patterns.
The app is perfect for tablets, its multi-touch support enabling you to zoom in or rotate to get the best possible view. But the authors haven't forgotten mouse users, either: you can click to move focus, scroll the mouse wheel to zoom in and out, and everything works just as you'd expect.
The program can also use multiple colour schemes to create new effects. If you find a particularly interesting point then you can bookmark it for easy access later. And a Save option enables you to save HD versions of your best patterns, ready to be shared with others.
