Installing Windows 10 Technical Preview
Getting and installing the new OS was surprisingly simple, when starting from a Windows 8.1 PC. No going to the Windows Store or installing preliminary Windows Update packs as previous preview versions have required. And it's not as time-consuming as Windows installations have been in the past. It took less than 20 minutes. Ready? Lets begin!
1. Choose a PC you don't need for everyday use. Windows 10 Technical Preview is a very preliminary build, so you should not install it on a PC you need to use regularly. It's just for trying out the operating system and sending feedback to Microsoft so that the company can improve the final release. On that note, don't expect privacy on the test Windows 10 PC: Microsoft will examine system files in trying to rectify the problem code. Back up any files on the test PC that you may need. The OS doesn't require a touch screen, though it does support them, albeit Microsoft claims touch support is unpolished. Also note that you may not be able to revert to an earlier version of Windows after this installation.
2. Check the specs for your test PC. If you're running Windows 8.1, there should be no problem. You can test for compatibility by downloading and running theWindows 8.1 Upgrade Assistant. In general, requirements aren't at all arduous. Here are Microsoft's minimum system specs:
• Processor: 1 gigahertz (GHz) or faster with support for PAE, NX, and SSE2
• RAM: 1 gigabyte (GB) (32-bit) or 2 GB (64-bit)
• Hard disk space: 16 GB (32-bit) or 20 GB (64-bit)
• Graphics card: Microsoft DirectX 9 graphics device with WDDM driver
5. Download the ISO disk image file for your system type. These are available in 32-bit and 64-bit flavors, and I recommend the latter for any PC with a 64-bit processor, which means pretty much any PC less than five years old. There are also three language choices: English (with U.S. and U.K. options), Chinese, and Portuguese.
6. Create startup USB with USB Download Toolkit. You could also burn the .ISO file to a DVD, but these days USB keys are widely available and the target PC may not have a disc drive. I used the trusty Microsoft USB download tool, which you can download from CodePlex Microsoft's open-source resource site
