Windows 7

I've just transferred my main work PC to Windows 7, and also changed to a solid state hard drive.

Windows 7 is great - once you've spent half an hour changing settings to get it the way you want.

And on the solid state hard drive it takes hardly any time to boot up.

For new Windwos 7 users, I suggest you google for terms like "windows 7 tips" - and you'll find helplful pages like this one
