WuMgr (Update Manager for Windows) is a utilities and tools freeware by David Xanatos. The freeware allows management of Microsoft Windows products that receive constant updates. It runs with the "Windows Update Agent API" so that it works smoothly on Windows operating system. It is also built with .NET programming language compared to Windows Update Mini Tool which is previously written in C/C++. This freeware identifies which update is missing on the computer and it downloads them. It is capable of delivering user-fine control of Windows 10 updates just like the prior OS versions of Windows. Having a freeware status means it is often updated to meet with changes.
