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 (see spoiler).
Spoiler for
Differences between Windows 8.1, Windows 8.1 Pro, and Windows 8.1 Enterprise
Basic Edition – Windows 8.1 Basic Edition (or just Windows 8.1) is intended for home users. This version includes the core features, but none of the business features. Basic Edition is great for those general consumers (mother, grandmother, father, step-uncle, far removed cousin).
Pro – Windows 8.1 Pro is the operating system intended for small and medium-sized businesses. It provides abilities such as joining corporate domains, participating in Group Policy, allowing involvement in Work Place Join and Work Folders, encryption and more. You can find a good list of business features in the The IT Guide to Windows 8.1. Note that some of the new business features in Windows 8.1 Pro require a server running Windows Server 2012 R2 somewhere in the organization.
Enterprise – Windows 8.1 Enterprise is the version that brings business premium features to Windows. Available through Windows Software Assurance, Windows 8.1 Enterprise includes all of the same features of Windows 8.1 Pro and then adds things like Windows To Go, DirectAccess, BranchCache, AppLocker, Virtual Desktop Infrastructure (VDI), and Windows 8 app deployment.
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.
