Discover WuMgr, the open source Update Manager for Windows.

WuMgr: an open source tool to manage updates of Microsoft Products on the Windows OS

WuMgr (Update Manager for Windows) is a tool to manage updates of Microsoft products on the Windows operating system. It uses the "Windows Update Agent API" to identify as well as download and install missing updates. It allows the user fine control of updates on modern (Windows 10) operating system versions, comparable to what windows 7 and 8.1 offered. This tool is inspired by the Windows Update Mini Tool, however in contrast to WUMT it is written in .NET instead of C/C++ and it is open source; thus its continued maintenance is ensured.

This tool allows you to easily check the recently installed updated by Windows Update or Windows Store and decide if you want to keep them or remove them easily with the graphical interface:
