With everyone and their brother/sister/mother/father/grandparents/hamster downloading and installing the Windows 10 Technical Preview this week there's still a lingering, burning question that rises to the top: which Technical Preview do I want and what's the difference?
With each Windows operating system, Microsoft has long offered different editions. Each edition is targeted toward different audiences. There's usually a consumer version, a Pro edition (for business-types), and an Enterprise offering (includes additional, Enterprise-related technologies). Each edition also comes with different pricing and different pricing models. For example, the Enterprise edition is only available through Windows Software Assurance.
Windows 10 works the same way. While the consumer preview won't release until early next year, Microsoft has made available a standard (or Pro) Technical Preview edition and an Enterprise version. The differences in features are pretty much the same as what you experienced with the Windows 8.1 release, detailed HERE.
So, yes, there's currently only two editions of the Windows 10 Technical Preview available, with the Consumer (or Basic) edition rolling out in a few short months. Its Microsoft's intent to cater to business first this time, hence the release of the Technical Previews targeted toward shops with IT organizations.
The differences between the General Technical Preview (Pro) and the Technical Preview for Enterprise are very similar to the Windows 8.1 model.
If you just want to test Windows 10 as a business OS, which includes general business management and functionality including Work Place Join, Work folders, encryption, etc., you want the General Technical Preview located HERE.
If you want to test things like Windows To Go, DirectAccess, BranchCache, and AppLocker, you want the Technical Preview for Enterprise located HERE.
