About this tag
The jscript persistence tag covers a Windows compatibility issue documented in Microsoft KB5105752. The notice explains that JScript globals, polyfills, and execution context loaded across multiple scripts may fail to persist on Windows 11 24H2, Windows 11 25H2, and Windows Server 2025. The issue can affect older payroll tools, installers, intranet applications, build systems, and automation that still depend on established scripting behavior. Coverage focuses on the registry-controlled compatibility feature administrators can enable when platform hardening disrupts legacy software. This archive is useful for tracking the change, affected Windows versions, enterprise impact, and practical considerations for restoring expected script behavior.
