A preview for PC experts
Windows Technical Preview is here today, but it’s a long way from done. We’re going to make it faster, better, more fun at parties...you get the idea. Join the Windows Insider Program to make sure you get all the new features that are on the way. If you’re okay with a moving target and don’t want to miss out on the latest stuff, keep reading. Technical Preview could be just your thing.
Download and install the preview only if you
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.
We're not kidding about the expert thing. So if you think BIOS is a new plant-based fuel, Tech Preview may not be right for you.
Things to keep in mind
Unexpected PC crashes could damage or even delete your files, so you should back up everything. Some printers and other hardware might not work, and some software might not install or work correctly, including antivirus or security programs. You might also have trouble connecting to home or corporate networks.
Also, if your PC runs into problems, Microsoft will likely examine your system files. If the privacy of your system files is a concern, consider using a different PC. For more info, read our privacy statement.
What does it work with?
Technical Preview should work with the same devices and programs that work with Windows 8.1, but you might need to update or reinstall some of them.
Drivers for basic functions like storage, networking, input, and display come with Windows. These drivers allow you to complete the Windows installation and connect to the Internet. You might be able to get more drivers from Windows Update.
For compatibility info, see the Windows 8.1 Compatibility Center.
If you use a mouse and keyboard
Your apps and devices should work as expected, though of course there will be exceptions. We’d love to know what you think about how the new Windows works with mouse and keyboard and whether it provides the best of new and familiar functionality for Windows and apps.
If you have a touch PC
Technical Preview works with touch, but some things will be rough and unfinished. More touch-friendly improvements are on the way. In the meantime, let us know what it’s like to interact with Windows and apps in the preview.
If you want to go back to your previous operating system
You'll need to reinstall your version of Windows from the recovery or installation media that came with your PC (typically DVD media). If you don't have recovery media:
For Windows 7 or Windows Vista: Before you update, you might be able to create recovery media from a recovery partition on your PC using software provided by your PC manufacturer. Check the support section of your PC manufacturer's website for more info.
For Windows 8.1 or Windows 8: You might be able to create a USB recovery drive. For more info, see Create a USB recovery drive.
Create a USB recovery drive
Applies to Windows 8.1, Windows RT 8.1
If you run into problems with your PC, a USB recovery drive can help you troubleshoot and fix those problems, even if your PC won't start.
Your PC might have come with a recovery image that’s used to refresh or reset your PC. The recovery image is stored on a dedicated recovery partition on your PC, and is typically 3-6 GB in size. To save space on your PC, you can delete the recovery image from your PC and use a recovery drive instead. Windows 8.1 includes a built-in tool to create a USB recovery drive. Windows will let you know how big the recovery partition is, and you'll need a USB flash drive at least that big.
Creating a recovery drive will erase anything already stored on your USB flash drive. Use an empty USB flash drive or make sure to transfer any important data from your USB flash drive to another storage device before using it to create a USB recovery drive.
To create a USB recovery drive
Swipe in from the right edge of the screen, and then tap Search.
(If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, and then click Search.)
Enter recovery drive in the search box, and then tap or click Create a recovery drive. Administrator permission required You might be asked for an admin password or to confirm your choice.
After the recovery drive tool opens, make sure the Copy the recovery partition from the PC to the recovery drive check box is selected, and then tap or click Next.
The checkbox is greyed out when your PC doesn’t have a recovery partition. The recovery drive will include only the recovery tools and a bootable image, but not a recovery image to use for refreshing or resetting your PC.
Insert a USB flash drive into your PC that is at least as large as the size indicated on the screen.
Tap or click the USB drive you would like to use for your recovery drive, then tap or click Next.
Tap or click Create.
The recovery image and necessary recovery tools will be copied to your USB flash drive, which will take a while, depending on your PC and the size of the recovery image.
When the process is done, do one of the following:
If you want to keep the recovery partition on your PC, tap or click Finish.
If you want to remove the recovery partition from your PC and free up disk space, tap or click Delete the recovery partition. Then tap or click Delete. This will free up the disk space used to store your recovery image. When the removal is done, tap or click Finish.
Some PCs don't offer the option to remove a recovery partition. If you experience this, there isn't a recovery partition on your PC that's using additional disc space.
Remove the USB flash drive.
This is now your Windows 8.1 recovery drive, and you'll need it if you ever need to refresh or reset your PC. Keep it in a safe place and don't use it to store other files or data.
If your PC came with Windows 8 and you upgraded it to Windows 8.1, your recovery drive will include Windows 8, and you’ll need to upgrade to Windows 8.1 after you refresh or reset your PC.

Many people expected that Microsoft would call the next version of its PC operating system "Windows 9" since the last major release was called Windows 8. Microsoft surprised most folks by announcing a couple of weeks ago it would actually be called Windows 10. So what the happened to Windows 9? According to Microsoft's Windows marketing head Tony Prophet today, "It came and it went."
Speaking as part of Salesforce.com's Dreamforce conference today, Prophet's vague answer is a sign that Microsoft wanted a true clean break from Windows 8, which most regard as a failed release of the OS. He added:
"Windows 10 is not going to be an incremental step from Window 8.1. Windows 10 is going to be a material step. We're trying to create one platform, one eco-system that unites as many of the devices from the small embedded Internet of Things, through tablets, through phones, through PCs and, ultimately, into the Xbox."
Do you think Prophet's statement on Windows 9 should be the final word on the matter of naming the next version of the OS
