Microsoft Details Strict Windows 10 Update Rules

Enterprises must follow strict Windows 10 update rules in certain circumstances to avoid being left out of future security updates, Microsoft said, with one rule requiring them to adopt the new OS by a certain period of time.

The strict rules apply to organizations that adopt the "current branch for business" (CBB) update scheme for Windows 10 suggested by the Redmond software giant.

Organizations adopting the CBB model will have "eight months" to apply Windows 10 updates. Should that period lapse without the update being applied, those organizations will not get future security updates for the OS. This eight-month deadline was mentioned by Helen Harmetz, a Microsoft senior product marketing manager, in a briefing for partners called "Staying Current with Windows."

Microsoft first talked about its servicing models for Windows 10 back in January. Last month, it described those models further in some Ignite sessions. However, the eight-month deadline wasn't mentioned on those occasions. It's new information that could be important for organizations with complex software environments to maintain.

Organizations wanting the more traditional update model for Windows with greater control over when operating system updates can be deployed can opt for the long-term servicing branch update model for Windows 10. However, the long-term servicing branch option only will be available to organizations that use the Enterprise edition of Windows 10.

The third update model for Windows 10 is called the "current branch." It's the Windows Update model that most consumers follow. Consumers tend to just accept what comes down the pipe from Microsoft, but they do have deferral options at present with Windows 7 and Windows 8. However, that situation will change with Windows 10. Current branch Windows 10 users won't have much ability to defer updates. Windows 10 Home edition users can at best defer updates for a "couple of hours," while Windows 10 Pro edition users will have the ability to defer updates "for up to 24 hours," according to a Microsoft MVP, answering a question in this Microsoft community forum page.

So far, Microsoft's servicing-branch models for Windows 10 look something like this table, as produced by Microsoft MVP Andre Da Costa in his Windows 10 FAQ:

Microsoft has used the threat of cutting off security updates before to herd its customers. For instance, it set a deadline for people to move to a Windows 8.1 Update from Windows 8.1, and it set a separate deadline for organizations to make that same move. This Windows 8.1 Update established a new OS baseline, allowing it to continue to get security updates. Those who didn't apply the Update had unpatched and potentially insecure systems.

Similarly, Microsoft has set a deadline of Jan. 12, 2016 for organizations to move to the most current Internet Explorer version per supported Windows. If they fail to make this move, then they will not continue to get future security updates for their browsers.

Even though Windows 10 is on its way for scheduled release on July 29, lots of details are still unknown about it. Windows 10 will be a free upgrade for consumers and some organizations. However, it's rumored that those accepting the free upgrade offer will have to also accept following the current-branch model (namely, Windows Update) in which the upgrades can't really be deferred.
