Reset Windows Update Agent

Using this script, you can completely reset the configuration of Windows Update and clear the local update cache. The script is applicable for both workstations with Windows 11/10/8.1/7 and Windows Server 2022/2019/2016/2012 R2/2008 R2. This script helps to eliminate most typical Windows Update errors when Windows stops downloading new updates or errors appear during the update installation.
