Windows applications and processes may be automated using a script in Windows Script Host. Viruses and malware could be written to exploit this ability. Thus, some suggest disabling it for security reasons. [20] Alternatively, antivirus programs may offer features to control .vbs and other scripts which run in the WSH environment.
In version 5.0, the functionality of VBScript was increased with new features including regular expressions; classes; the With statement; [8] the Eval, Execute, and ExecuteGlobal functions to evaluate and execute script commands built during the execution of another script; a function-pointer system via GetRef, [9] and Distributed COM (DCOM ...

In his 2001 essay Strategy Letter IV: Bloatware and the 80/20 Myth, [3] Joel Spolsky argues that while 80% of the users only use 20% of the features (a variant on the Pareto principle), each one uses different features. Thus, "lite" software editions turn out to be useless for most, as they miss the one or two special features that are present ...
It has since been bundled with all subsequent versions of Windows. 10 years later, PowerShell went open-source and cross-platform. It can operate both interactively (from a command-line interface) and also via saved scripts (.ps1 files). The scripting syntax can further expand PowerShell via script modules (.psm files) and binary modules (.dll ...
