If you've bought a PC with Microsoft Windows Vista preinstalled, chances are it isn't the all-singing, all-dancing Ultimate version. However, it's possible to get Ultimate's power from Vista Basic using third-party downloads.
But one thing any Vista Home user should add, seeing as they don't get the benefit of the Business-only BitLocker encryption features, is DESlock+. Although it isn't feasible to add exactly the same levels of system-partition hardware encryption, DESlock+ does a fine job nonetheless. It provides fully transparent encryption for files, folders and email. The encryption keys can be stored on your PC, a CD or external USB stick, and there are four key slots to enable secure email sharing with your closest contacts. You get a 60-day evaluation period, but it works after that with just a nag screen for company, and personal users can register for a free licence. There's also a Vista Gadget version that lets you drag and drop any file onto it for immediate encryption just by entering a password, which is why DESlock+ gets our recommended award this month.
