Windows 8 Same Memory Usage as Windows 7 is continues to work on Windows 8, the company is finding ways to limit memory usage by Windows 8 for better memory management can prolong battery life. Microsoft wants to ship Windows 8 with the same system requirements as Windows 7. One of the keys to Windows 7's roaring success in the market was delivering on the promise of using less memory than its predecessor, Windows Vista, while being just as fast if not faster.

One of the ways Microsoft plans to achieve this is by reducing the amount of RAM that Windows 8 utilises for operating system tasks. The benefits are increased performance for applications and an increase in battery life for laptop and tablet devices. Windows 8 continues this tradition. In the //build/ Conference, Windows Division president Steven Sinofsky wowed the crowd with a screenshot of Task Manager running on Windows 7 and Windows 8. The netbook, the same one used for demonstrating the Windows 7 pre-beta three years ago, had a reduction of almost 120 MB of RAM usage.

The company’s goal with Windows 8 from the beginning was to ship with the same system requirements as Windows 7. They tried to remove blocks of system memory that are already duplicated in other running programs.

Service changes and reductions: Remove about 13 service, move a different set of services to “manual" start, and make some of the “always running" services move to a “start on demand" model. The software giant has improved the number of services in Windows 8 and set a massive of them to start manually. Microsoft has also introduced a “start on demand” model for services to allow them to only start when required. Plug and Play, Windows Update, and the user mode driver framework service are all trigger-started in Windows 8, in contrast to Windows 7, where these services were always running.

Microsoft is cutting down the footprint of memory use whilst executing applications. Windows 8 will consolidate “hot” items in system memory to bring down the overall runtime memory cost. Microsoft went through low-level components of Windows, some dating as far back as the original Windows NT, and reworked code and data structures. The result was separating portions of memory that are frequently referenced from those that are accessed occasionally., which led to across-the-board memory usage reduction amongst Microsoft employee workstations.
