Microsoft has once again made the Windows 7 beta available for download after its servers were overwhelmed with users trying to download the operating system.

On its Windows 7 site, Microsoft posted a note saying "The Windows 7 Beta is now available for download." The Windows 7 site lists a page where the beta can be downloaded.

On Friday, Microsoft struggled to keep its website online as users overloaded the company's servers. Microsoft's main website and the download page the were often unreachable.

Company officials said activation keys for the code would be capped at 2.5 million, but users who try the beta after that limit is reached will be able to use it for at least 30 days.
