Microsoft is introducing optimisations to make Windows 11 more efficient on PCs with 8 GB of RAM, yet retains the high memory requirements for AI functionalities, highlighting ongoing challenges amid a global memory shortage.
Microsoft is preparing changes to Windows 11 that should make the system feel lighter on PCs and laptops with 8 GB of RAM. That is a sensible target, but it should not be mistaken for a shift in Microsoft’s hardware expectations. Even with the planned tuning, 8 GB machines will not suddenly become equivalent to higher-spec devices.
The main point is that the optimisation work does not alter the platform’s requirements for Copilot+ or for basic on-device AI functions. Those features still need at least 16 GB of RAM, and Microsoft’s guidance continues to treat that figure as the practical baseline. In other words, the company may make Windows 11 less demanding on modest systems, but it is not lowering the bar for its AI ambitions.
That matters because the market is moving in the opposite direction. According to reports from Tom’s Hardware, The Verge and TechRadar, a global memory shortage and rising component costs have pushed some laptop makers back towards 8 GB configurations. Microsoft’s response appears aimed at keeping Windows 11 competitive on those entry-level and mid-range systems, particularly as the company tries to avoid pushing users towards alternatives such as Linux, macOS or SteamOS.
Even so, the limits of 8 GB remain obvious. Windows 11 can already use several gigabytes shortly after boot, and modest multitasking can quickly exhaust available memory. Lightweight local AI models may still run on such systems, but they will not deliver the same experience as a machine with 16 GB or more. The practical message is unchanged: Microsoft may trim overhead, but 16 GB remains the safer recommendation for most users.
