Windows 8 comes in two versions – Standard and Pro. Microsoft doesn’t offer a trial version of either of these, but if you are willing to experiment with the new OS first, it does have a 90-day developer edition that anyone can use to evaluate Windows 8 before making the switch.

This evaluation provides a 90-day trial of Windows 8 Enterprise edition. Both 32-bit and 64-bit versions are available as ISO images in the following languages: Chinese (Simplified), Chinese (Traditional), English, English (UK), French, German, Italian, Japanese, Korean, Portuguese (Brazil), and Spanish.

In order to use this evaluation, you must register and the product must be activated online with Microsoft.
