Windows Beta Repository
Please note that beta versions of any kind of software can be unreliable. I do not recommend using a beta version of Windows as your daily operating system as you may experience issues. I or Microsoft are not responsible for any issues that you may have, and it is highly recommended that you back up your data frequently (that's if you have any important data on your install of Windows). I only recommend using beta versions of software for evaluation purposes.
Also, I don't have every build of Windows available for download here due to the fact that some builds are hard to come by, but, keep your eyes peeled as I gradually add more to this page. If you would like to stay informed on what I add or change to this page, head on over to the WEBSITE UPDATE LOG.
If you are looking for the download links for the final, production-ready versions of Windows, they are on the WINDOWS REPOSITORY page.
