By creating a server that serves updates and other products from Microsoft, you can save internet consumption and speed up the update process.

Update Services (WSUS) is a feature of to manage the distribution of updates released by Microsoft Update to computers on your . will be very useful if you have to manage many computers.

Updates from Microsoft products can be hundreds of Megabytes in size, and can even reach a size of over one Gigabyte. If the number of computers in the is large, it is certainly very inefficient if each computer has to download to Microsoft. Because this will burden internet usage and require a long download time.

By creating a Server that serves an update, a direct update to Microsoft is only performed by one Server computer. Meanwhile, computers in other networks will download updates to the server. In this scenario, the update process from the computer does not require internet access because it uses a local (LAN) and, of course, the download speed is also very fast.
