How to get your PC ready for Windows 7

Windows 7
Get your PC ready for an effortless upgrade

The process of installing a new operating system has become almost a ritual.

Do you worship at the throne of backing everything up on a library of neatly labelled CDs, run the upgrade procedure and then gently reinstate your content?

The upgrade path

It's worth pointing out that every retail version of Windows 7 includes all the flavours of the operating system, but your key tells your machine what to install. So, if you buy Home Premium and then find yourself inheriting a bucketload of RAM, you'll be able to purchase an upgrade key and install Ultimate from your original disc.

Amazon has also said that the prices mentioned above will apply indefinitely, which means us Brits are getting a better deal than the Yanks for once.

The system requirements for 32-bit Windows 7 are the same across the board: 1GB of RAM, 1GHz processor and 16GB of hard drive space. If you're running a 64-bit installation instead then those system requirements are upped to 2GB of RAM and 20GB of hard drive space.

The Windows Aero translucency effects also need a 128MB graphics card with support for DirectX 9, which we expect you already have. If you don't, you can pick up a basic, rubbish one for less than £50.

Windows 7 on netbooks

Unfortunately, those requirements mean running Windows 7 on a netbook is a different proposition to bunging it on your PC. Cheapo netbooks are usually supplied with just 512MB of RAM, which won't be enough to run Windows 7. Upgrading to 1GB is relatively cheap and painless, but we'd recommend getting 2GB for an optimum performance boost.

From there, it's a matter of removing one of the backplates on your netbook, popping out whatever's lurking in there at the moment out and then sticking the new sticks of RAM in. In addition, SSDs have been increasingly finding their way into netbooks, but their advantage of being quick and robust is undone by the double whammy of the space hungry Windows 7 and the drives' capacity limitations.

Some netbooks with SSDs – such as Dell's Mini 9 – only include 8GB drives, for example, which makes installing any version of Windows older than 2000 impractical and impossible. If you're desperate to get Windows 7 on one of these devices, you'll have to pluck the hard disk out and replace it.

TOUCH ME GENTLY: Touchscreen PCs and Windows 7: a match made in fingerprint heaven

Then there's the whole issue of installing Windows 7 on machines that often don't have optical drives. This boils down to sticking the installation files on a bootable USB flash drive and running it from there.

If you can't be bothered with this rigmarole, it might be worth waiting a few months: there are rumours of Microsoft releasing a Windows 7 USB drive. And if you're lucky enough to own a touchscreen PC, Windows 7 will work with it out of the box. We've seen more and more of these devices recently in the form of Asus' forthcoming T91 netbook and MSI's luscious WindTop.

Windows 7 has been engineered from the ground up to work with pokable screens and it will automatically chunkify your desktop when it detects a USB touchscreen connection.
