Important

Remember, trying out an early build like this can be risky. That's why we recommend that you don't install the preview on your primary home or business PC. Unexpected PC crashes could damage or even delete your files, so you should back up everything.

If you want to stop using Windows 10 Technical Preview and return to your previous version of Windows, you'll need to reinstall your previous version from the recovery or installation media that came with your PC—typically a DVD. If you don't have recovery media, you might be able to create a USB recovery drive.


After you install Windows 10 Technical Preview, you won’t be able to use the recovery partition on your PC to go back to your previous version of Windows.

you know all the bugs even then you offer to download.
Windows 10 beta ver. probably will be released in April 2015 and that ver. would be user friendly.
technical preview ver. is only for developers.
