How to Automate Windows Updates Using PowerShell: Short Overview

Patch management is a crucial aspect of IT infrastructure administration, just as Windows Workstation backup. With the right patch management solution, you can enhance your system by testing or installing the latest software updates and patches. Patches are regarded as temporary fixes for existing issues between full-scale software releases. If patch management is effectively performed, you can promptly address vulnerabilities of your system and mitigate any potential threats.

Windows offers its own patch management solution – Windows Update. However, many IT administrators still find the patch management process too complex and time-consuming.
