Microsoft has lifted an upgrade block that prevented certain users of the Safe Exam Browser from installing the Windows 11 2024 Update due to compatibility concerns. The block was initially implemented in September to protect users from issues with Safe Exam Browser version 3.7 or earlier. Users are encouraged to upgrade to Safe Exam Browser version 3.8 or later before proceeding with the Windows 11 24H2 update. If users still encounter the safeguard hold after 48 hours of updating, they should contact Safe Exam Browser Support. The Windows 11 24H2 feature update is now available for all compatible PCs, except those under safeguard holds. Microsoft has resolved issues that previously blocked the update for some users and has removed other compatibility holds for specific devices and applications. However, some upgrade blocks remain due to incompatible hardware and software. Windows 11 24H2 began its rollout in May 2024 for enterprise testing, with a broader release in October.
