About this tag
The compatibility-regression tag on WindowsForum.com covers issues where newer software versions fail to run on older Windows releases due to missing API sets or runtime components. A recent example involves Firefox Nightly 143 failing to launch on Windows 10 builds prior to version 1803, with an error about api-ms-win-core-console-11-2-0.dll being absent. This is not an intentional deprecation but a genuine compatibility regression caused by the application depending on a runtime API set that does not exist on those older systems. Discussions focus on identifying such regressions, understanding the underlying API dependencies, and finding workarounds or fixes for affected users.
