Microsoft advises upgrading Safe Exam Browser to version 3.8 or later before installing the latest Windows update. Users who’ve already upgraded their SEB version but remain blocked after 48 hours should contact Safe Exam Browser Support for further assistance.

The issue specifically impacts Windows 11 version 24H2 users, no server editions are affected.
