Microsoft’s Antoine Leblond detailed the availability on a blog post on Tuesday but, as PCWorld first noticed, the news promoted a backlash from Windows developers.
“How are we supposed to test our software for Windows 8.1? The day it will be automatically installed on users’ machines? So we—software developers—can take blame that applications don’t work on Windows 8.1?,” wrote one person.
Another developer agreed, stressing that the development community needs to get its hands on the update prior to consumers.
“Most of us actually want to support Windows 8.1, a lot of us want to get apps ready for the awesome 8.1 features, but we can’t properly do that unless we get the RTM bits before the public gets the Windows 8.1 update.”
Microsoft responded to the criticism by saying that there are still ways developers can test Windows 8.1 prior to release, namely by using the preview editions of Windows 8.1 and Visual Studio 2013 — which is due to launch later this year.
Windows 8.1 is slated to start shipping on October 18.
