Want to save a packet on editing and presenting your wedding photos and videos? Windows has launched a new Movie Maker application. The free downloadable software lets you create slick films and slideshows at home. It's super easy to use - you can edit your digital footage and pictures, filtering out any unflattering shots; re-order them; insert snaps from your guests; and add professional touches such as visual effects, film credits and captions. You can even add music effects including setting your wedding tracks to certain images and sections of film - so if the music is muffled in the film footage of your first dance, you can add in the track manually, so it's crystal clear. The final cut can be burnt to DVD, uploaded to social networking sites such as Facebook and Youtube, emailed or sent to mobile phones. It will make the perfect memento for your guests - and it should be a lot of fun making it! Download at windowslive.co.uk.

Check out the iGuide to wedding etiquette (£1.99) and get in shape for your big day with all manner of fitness and weight-tracking applications. And for your honeymoon? Get travel guides, phrasebooks and currency converters - and before you go, preload your gadget with songs and films so you can tune in while you're away.

Karaoke and cocktails are a match made in hen-do heaven. There's nothing better than a good girlie warble (who cares if you can't sing?). If you're feeling flush, then go for the blow-the-budget Lucky Voice Pop-up Party, where the karaoke bar comes to you - along with a a sound system, an audiovisual kit, two microphones and a bartender who will serve 100 cocktails (from £2,300; less without the drinks).

You don't have to spend anything like that much: you can hire a room at Lucky Voice (which has venues in London, Manchester, Cardiff and Brighton) from £20 an hour for four people. In fact, you can have your perfect karaoke night - and it needn't cost you a thing. Lucky Voice Home (luckyvoice.com/home) lets you create playlists of all your favourite tunes and stream them to your computer. There are thousands of songs to choose from and it's totally free. Since the songs are gratis, you could always add a professional touch with the Lucky Voice Party Box (£49.95 from luckyvoice.com), which contains a mixer and a neon pink mic. But if you want to really bling it up, get your hands on a flashy new limited-edition gold mic (£39.95 or £69.95 as part of the Party Box; available from Selfridges).
