Windows 10 Insider Preview Build 20251 Releases

Microsoft has launched Windows 10 Insider Preview Build 20251. The version has no new features and mainly fixes various known problems.

Earlier, we mentioned that the current development test version has been switched from the manganese branch (MN_RELEASE) to the iron branch (FE_RELEASE). The change of the version code means that the branch of the current version has changed.

The branch codenamed Iron should be a new version next spring, but Microsoft emphasizes that the version currently in the development test channel does not belong to any particular branch.

So whether it is the previous version or the next new version, the new features in these versions are not bound to any specific version and may be released at any time.
