I know there will be an upgrade to Windows 10 for people actually using Windows 8.1, etc.
How can a Linux User give a try Windows 10?
Do I need to buy a License or there will be some kind of ISO image available for free download at the beginning?
Thank you!
After the official launch on July 29 they will probably reopen the Windows Insider program for signups, so keep an eye on <a href="https://insider.windows.com/" rel="nofollow">https://insider.windows.com/</a>
If your just testing I think there are Technical Previews. For example Parrallels for OS X has an easy way to download them. I think you could probably get something similar for Linux via something like this <a href="https://insider.windows.com/" rel="nofollow">https://insider.windows.com/</a>
