Of course, one cannot discuss .NET Framework 4.7.2 on Windows 7 without acknowledging the security paradox. Windows 7 no longer receives free security updates, yet .NET 4.7.2 continues to receive critical security patches via the Extended Security Updates (ESU) program or on Server 2008 R2. The offline installer, however, installs the base version. Consequently, a responsible user or administrator must immediately apply the latest cumulative updates for .NET Framework after running the offline installer. In this sense, the offline installer is not a complete solution but rather a foundation—a reliable starting point that must be supplemented with post-installation patching. For air-gapped systems (those never connected to the internet), the offline installer is an absolute necessity, but those systems also require periodic manual updating using subsequent offline rollups.
