Secretly eating Ram without being considerate of the price now 🍋
More recently, Windows 11 began to be increasingly questioned by users about the use of system resources, especially RAM, because Microsoft began to automate the behavior of several system services since it was turned on in Windows 11 versions 24H2, 25H2, as well as Windows Server 2025, from the original running only when needed, resulting in some services running behind the scenes all the time without the user realizing it.
.
One of the most watched services, Delivery Optimization, the main feature of Windows Update, is responsible for helping distribute peer-to-peer update files to reduce net usage and speed up updates.
But there was a Reddit user called Niff _ Naff who did a real test, following the Delivery Optimization process that the system used called DoSvc for a long period of time. The result was that DoSvc had increased RAM consumption, even without downloading any updates, and no memory returned to the system.
.
This behavior networks memory leaks or can be caused by inefficient memory management, causing a machine with 8GB or 16GB of RAM to experience problems that are used gradually.
.
Although Delivery Optimization is designed for speed and bandwidth savings, behind-the-scenes operation that requires RAM for cache and constantly on the connection, bugs can become a system burden. Instead, we can access Settings > Windows Update > Advanced options > Delivery Optimization to limit or disable file sharing updates.
.
This clearly reflects the overview of Windows 11. The problem is not just the increased features, but also the management of resources invisible to users. It's no surprise that Microsoft is starting to recommend that modern PCs should have at least 16GB of RAM to support more and more concurrent system services.
