The Windows 8.1 Enterprise Preview became available for download on Tuesday.
Microsoft requires registration to access the Preview download, which is set to expire in just over five months on Jan. 14, 2014.
Microsoft has not said much about  Windows 8 Enterprise since announcing the Windows 8 editions early last year, although using the Enterprise edition will require  having a Software Assurance licensing agreement in place. The other editions  are Windows 8 and Windows 8 Pro, both of which will be getting 8.1 updates,  presumably next month. Microsoft previously announced that original equipment  manufacturers would get Windows 8.1 in late  August.
Lifecycle Support
Microsoft's announcement on Tuesday indicated that Windows 8.1 will have the same  lifecycle support timeline as Windows 8, with both products exiting  "extended support" on Jan. 10, 2023. However, the announcement added a  confusing detail, suggesting that Windows 8 users will have to move to Windows  8.1 two years after general availability:
  "Windows 8 customers will have two years to move to  Windows 8.1 after the General Availability of the Windows 8.1 update to  continue to remain supported under Windows 8 lifecycle -- and there are deployment  tools and guidance available to help make these updates seamless  for customers."
Since the lifecycles are the same for Windows 8 and Windows  8.1, it's not clear why Microsoft indicates that there is a two-year period to  switch and still have support. A Microsoft spokesperson explained that this policy is based on Microsoft's service pack concept.
"Historically, we have  a similar support approach related to service pack support with 12 to 24 months  of support," the spokesperson said via e-mail. "Unlike service packs that are typically just a collection of fixes,  Windows 8.1 has new features and enhancements -- however, we designed Windows  8.1 to give customers an ability to deploy this update in a manner that is  similar to how customers deploy service packs, therefore the support approach  is similar."
A second Microsoft announcement today indicated  that Microsoft's tools to help with deployments will be available concurrently  with the release of the Windows 8.1 operating systems.
"Final versions of the deployment tools, including the  Assessment and Deployment Kit for Windows 8.1, Microsoft Deployment Toolkit  2013, and System Center 2012 R2 Configuration Manager, will be available at the  same time as Windows 8.1 Enterprise to ensure you can begin deploying this new  version of the operating system right away," the  announcement states.
While that announcement indicates that there is an automated  process for moving from Windows 8 Enterprise edition to Windows 8.1 Enterprise  edition, that advice doesn't seem to apply to the Preview. The download page  for Windows 8.1 Enterprise Preview offers a cautionary statement, warning that  organizations won't be able to upgrade from the Preview.
"Windows 8.1 Enterprise Preview should be installed on  a test machine," the download page states. "Following the preview  period, it is not possible to upgrade to a licensed working version of Windows  8.1 Enterprise. Personal data will be kept on your test computer, but the  Windows OS and your applications will need to be reinstalled when moving from  the preview to production bits."
Microsoft offers plenty of cautionary advice about  installing the Windows 8.1 Preview, which is summarized here.  It's possible to lose applications using the Preview, so Microsoft advises  backups and only using the Preview OS on test machines.

New Features
  New features in the Enterprise edition of Windows 8.1  include the Start Screen control, Windows To Go Creator and Windows Enterprise  sideloading. The Start Screen control lets IT departments control the  appearance of desktops across the organization, including blocking user changes  to the Start Screen. Windows To Go Creator seems to be a new phrase for  Microsoft's portable  Windows 8 desktop scheme, in which a corporate Windows 8 desktop can be  imaged to a USB drive for remote use. "Sideloading"  is Microsoft's term for publishing line-of-business apps via a portal page,  without having to lodge them in the Windows Store, and Microsoft is requiring Software  Assurance to do that, or organizations can buy "sideloading keys,"  according to a Microsoft spokesperson. 
"A sideload product key would be needed if the computer  is not Active Directory-joined, and this key is provided to SA for Windows  customers at no extra charge," the spokesperson explained by e-mail. "If  an organization does not have Software Assurance they can purchase sideloading  keys."
Some of the other features that are unique to Windows 8.1  Enterprise edition aren't particularly new as they are present in the Windows 7  Enterprise edition. Those features include AppLocker, which  enables policies to be set on what apps and files can reside on a device, BranchCache,  which is designed to make content access by branch offices in a wide area  network more efficient, and DirectAccess, which lets users connect without the  hassles of a virtual private network.
Microsoft is also touting virtual desktop infrastructure  capabilities with the Enterprise edition of Windows 8.1, but it requires deploying  Windows Server 2012, too. Similarly, AppLocker, BranchCache and DirectAccess appear  to require using either Windows Server 2008 R2 or Windows Server 2012. 
Microsoft demonstrated a lot of the Windows 8.1 features in  June at its TechEd events. Some of the business customization capabilities,  such as "assigned access," which allows an IT department to control  Windows Store access on a device, were described  by Jon DeVaan, corporate vice president for Windows development. Microsoft  added a Start  button and boot-to-desktop capabilities in Windows 8.1, as well as some networking  improvements.
Microsoft lists all of the Windows 8 Enterprise features here,  while all Windows 8.1 features can be found at this  page. Microsoft has been updating Windows 8.1 on a monthly basis so far,  with the OS having received three  waves of updates that fix features or improve reliability.
