Windows 11 26H2 Update Quietly Boosts System Memory Efficiency

Reports surfacing from Windows Latest and Reddit indicate that memory savings are substantial, with some users on 16GB laptops reclaiming up to 2GB or even 3GB of RAM. These gains are most visible during idle states, though improved memory management appears to benefit overall system responsiveness when running resource-heavy applications.

Technical observers point to the new Low Latency Profile as a potential driver for this shift. This feature prioritizes finishing individual tasks as quickly as possible, allowing the CPU to shift into an idle state faster than before. By optimizing how the processor handles these requests, the system reduces the overhead that typically clogs memory. Although Microsoft previously promised general performance refinements for the platform, the company has yet to officially attribute these specific memory savings to the 26H2 update.
