Isolate: Run the legacy application on a virtual machine (VM) with no internet access.
Use Server Core: If you must run it on physical hardware, disable all unnecessary network services.
Application Whitelisting: Use AppLocker or WDAC to ensure only the specific legacy app can execute.
Open Control Panel → Programs and Features.
Look for "Microsoft .NET Framework 2.0 Service Pack 2".

Granular Module Control: Administrators can toggle specific legacy libraries (e.g., ASP.NET 2.0, Windows Communication Foundation 3.0 foundations) on or off individually. This is critical for "security hardening" on modern systems, allowing users to run legacy apps while disabling unnecessary legacy network stacks that pose security risks.
Dependency Mapping: The manager scans installed applications and maps them to specific .NET 2.0 dependencies. If an admin tries to disable a library, the tool warns which installed legacy software will break, preventing accidental downtime.
One-Click Compatibility Troubleshooting: Instead of manually hunting for "app.exe.config" files to force legacy compatibility modes, this feature provides a "Fix Legacy App" button. It automatically generates the correct XML configuration files to force a specific application to run under the 2.0 runtime within the modern 4.x environment.
Offline Repair Source Path: For offline installers, the manager remembers the source path of the installation media. If system files become corrupted, it can repair them immediately from the local cached installer rather than attempting to connect to Windows Update (which legacy versions often struggle to reach efficiently).
