MpashoNews Kenya: Windows 10 download is out download it from here

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.

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.

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
