Microsoft's Windows 10 is now available to download, though it is only a "technical preview".

The company promised when it unveiled Windows 10 that it would launch a technical preview of the unfinished software the following day at no cost, and now that day has come. If you’re a developer, or maybe just daring, you can download it now. Keep in mind Microsoft stressed the preview is a very early build of the final version expected to launch in mid-2015.

In other words, the software likely has many bugs and could crash your computer. It should therefore not be installed on a computer used for day-to-day purposes. That said, if you’re a developer, IT professional, or just tech savvy, the preview is definitely worth checking out. But be sure to browse through Pocket-lint's tips below before getting started.

Should you download the technical preview?

Microsoft has listed a bunch of criteria, which you should review before downloading and installing, as it establishes whether you're an ideal candidate to test the technical preview.

  • Want to try out software that’s still in development and like sharing your opinion about it
  • Don’t mind lots of updates or a UI design that might change significantly over time
  • Really know your way around a PC and feel comfortable troubleshooting problems, backing up data, formatting a hard drive, installing an operating system from scratch, or restoring your old one if necessary
  • Know what an ISO file is and how to use it
  • Aren’t installing it on your everyday computer

Does your computer meet the minimum requirements?

Before downloading, better double-check to make sure your computer has a 1GHz or faster processor, at least 1 GB of 32-bit RAM or 2GB of 64-bit RAM, 16 GB of free hard disk space, and a Microsoft DirectX 9 graphics device with WDDM driver.

More information about technical requirements is available here. Take note that the technical preview won't run on Windows RT systems.

1. Create or make sure you have a Microsoft account as well as internet access.

2. Prior to downloading anything, back up your data.
