Are you ready to walk on the wild side? Windows 10 is on the horizon, and even though it’s still roughly three-quarters of a year away from completion, Microsoft’s giving IT Pros and PC enthusiasts an early taste of what’s to come with the Windows 10 Technical Preview.
This isn’t like Windows 8’s Consumer Preview; the Windows 10 Technical Preview is being released via a new “Windows Insider” program that asks for user feedback and even provides private forums for discussing trouble spots with Microsoft engineers. Lots of things are sure to change going forward, from features to basic elements of the operating system.
All that said, are you still curious? Can’t resist the lure of the bleeding edge? Just want to run away from Windows 8? Here’s how to install the Windows 10 Technical Preview right now.
Actually, you won’t be installing the Technical Preview for a few minutes yet. Didn’t you hear the part about this being a very early pre-release build? That means catastrophic errors are an all too real possibility.
Don’t take my word for it: Here’s part of the terms of service you agree to when you sign up for Windows Insider (emphasis Microsoft’s):
“The Program Services include experimental and early prerelease software. This means that you may experience occasional crashes and in rare cases data loss. To recover, you may have to reinstall your applications, the operating system, or re-flash your device. Using the Program Services on some devices may impact your warranty (check with your device provider). By participating, you agree to frequently backup your data.”
In case that didn’t make it clear enough, back up your data before you start. Dump your pictures in Dropbox, drag your documents to an external hard drive, whatever works! Just make sure your data is safe and secure in case something bad happens when you’re installing the Windows 10 Tech Preview. (PCWorld’s absurdly simple backup guide and tools for backing up your data for free can help if you’re stumped.)
Windows 10 Technical Preview requirements
Before we get too involved, it’s worth noting that the Windows 10 Technical Preview is currently limited to PC and Windows tablets with x86 processors—there’s no version for Windows RT tablets and their ARM processors available. (Sorry, Surface RT owners.) If you’re unsure which version of Windows your tablet is running, right-click on the “This PC” icon in File Explorer and select Properties. Your Windows edition information will be at the top of the window that appears.
Here are Windows 10’s other hardware requirements, which are just as modest as Windows 8.1’s.
- Processor : 1GHz or faster with support for PAE, NX, and SSE2
- RAM : 1GB (32-bit) or 2GB (64-bit)
- Hard disk space : 16GB
- Graphics card : Microsoft DirectX 9 graphics device with WDDM driver
Some additional notes: You’ll also need a Microsoft account and Internet access. And if you want to access the Windows Store or use Windows Apps, your monitor’s resolution will need to be at least 1024x768. The Windows 10 Technical Preview is available in English, Chinese Simplified, and Brazilian Portuguese.
Still here? Now head over to preview.windows.com and click the Get Started button. After registering for Windows Insider, you’ll be prompted to download the Windows 10 Technical Preview. Download the appropriate Technical Preview build for your machine—the “This PC” or “My Computer” Properties window can also tell you if you have a 32-bit or 64-bit processor under the “System type” field.
Jot down the product key for the Technical Preview, too. You’ll need it to install the operating system.
Installing the Windows 10 Technical Preview
With all that done, it’s time to get the Tech Preview on your PC! But since it’s a very early pre-release build of the operating system, you won’t want to overwrite your PC’s operating system with Windows 10—especially since doing so renders Windows Media Player incapable of playing DVDs and removes Windows Media Center entirely from upgraded Windows 8.1 Pro installations.
If you have a superfluous computer lying around, sure, feel free to install the preview on that. But most people will want to install the Windows 10 Technical Preview either in a virtual machine, or on its own hard drive partition.
In a virtual machine
Installing it on a virtual machine is the easiest option. Grab VirtualBox, Oracle’s stellar no-cost VM tool, and you’ll be ready to rock. Download the Windows 10 Preview and configure it in VirtualBox using mostly the same steps outlined in PCWorld’s guide to test-driving Windows 8 in a virtual machine.
But there are three very, very important differences when you're creating the Windows 10 VM when compared to the article above. First, when you're initially setting up the Windows 10 VM, select "Windows 8.1" as the operating system type. And once you’ve got the Windows 10 VM set up, you need to open its Settings > System. In the Motherboard tab, ensure the box next to “Enable EFI (Special OSes only)” is checked, as well as the “Enable PAE/NX” box under the Processor tab.
It's worth noting that I encountered troubles installing the 64-bit version Windows 10 on VirtualBox—the installation hung right after the "Press any key to boot" screen, stuck forever on the Windows logo against a black background. Several others have been successful in getting it to work, however, and I was able to install the 32-bit version of Windows 10's Technical Preview successfully.
I'll try downloading the 64-bit version again later and let you know how it goes.
In a hard drive partition
Running operating systems in virtual machines also sacrifices some performance, especially if you don’t have extra CPU cores or much RAM to dedicate to the task. If you want to experience the Windows 10 Technical Preview natively, you can create a new partition on your hard drive and install the preview there. (It’s best if you’re able to do this on a secondary PC, just to be safe.)
PCWorld’s guide to installing Windows 8 on a new partition can walk you through the process—the same basic steps apply to the Windows 10 Technical Preview, and Windows 8 handles hard drive partitioning the same way Windows 7 did. Note that Windows 8 includes native tools for burning a bootable ISO to a DVD, however—simply right-click on the Windows 10 ISO file and select Burn disc image.
Living on the edge
There you have it. Enjoy the sweet, sweet desktop improvements and let Microsoft’s team know if you hit any rough spots. You'll find a feedback tool baked right into the Windows 10 Technical Preview. That’s why you joined the Windows Insider program after all. Right?
