Windows 10 Technical Preview is Available–Time to Start Thinking About Compatibility

Every new version of Windows brings new features and opportunities for developers, but also some challenges with compatibility of existing applications.  It’s never too early to plan ahead, so big thanks to Premier Developer consultants Maarten Van De Bospoort and Pat Altimore for this piece on Windows 10 compatibility.

The beginning of this month Windows 10 Technical Preview was announced and made available for download.  Just like Windows 7, Windows 8, and Windows 8.1, Windows 10 will have a high level of compatibility with its predecessor. Now that a preview is available, it’s a good idea to start planning to find any potential compatibility issues. Keep in mind though that this is an early preview and things will change before release.

Trivial Changes?

Even the simplest changes in the OS can cause compatibility issues. For example, version checking causes a large portion of all compatibility issues when a new version of Windows is released. As a result, this influences the version number reported by Windows. It’s true. Windows 2000=5.0, Windows XP=5.1, Windows Vista=6.0, Windows 7=6.1, Windows 8=6.2, Windows 8.1=6.3. For more on version checking, one of this blog entry’s co-authors and Premier Developer consultant, Pat, has a post that talks about the version check issue and gives guidance on avoiding this potential issue.

What’s Been Cooking?

Windows 10 is poised to become the most successful version ever. So, why not get ahead of the curve? Let’s contemplate two different categories of applications. First, if you have an application that currently runs on Windows 7 or lower, you’ll want to test and fix your app for Windows 8.1. This is a released and stable version of the OS. To get started, Microsoft produces a “Compatibility Cookbook” document that details the changes to the OS that could affect compatibility. You can find the previous cookbooks here: Vista/Server 2008, Windows 7/Server 2008 R2, Windows 8/Server 2012. (The Windows 10 compatibility cookbook isn’t available at this time.)

Second, if your application is already running smoothly on Windows 8.1, you should try it out on Windows 10. Of course, keeping the afore-mentioned preview disclaimer in mind.

    Is the Windows 10 compatibility cookbook release or not?

    If not, do you know when will it be available?

    Thank you!

    At the time we wrote this post, no decision had been made on a new cookbook for 10.  There is a high level of compatibility going from 8.1 to Windows 10 for applications and so for Windows 10, there is not a cookbook at this time.  If you have an application that targeted an OS prior to 8.1, the previous cookbooks still apply to Windows 10.
