Microsoft rolls out memory optimizations to speed up Windows 11 on 8GB PCs

Microsoft has issued memory management updates aimed at improving Windows 11 performance on systems with 8GB of RAM. Windows chief Pavan Davuluri announced that based on internal lab tests, the operating system is now up to 20 percent more responsive and up to 40 percent faster at multitasking compared to January 2026 builds. Accessing the enhancements requires updating Windows 11 version 26H2 to build 26300.9818 or later, though ZDNET notes build 26300.9711 is also viable if users bypass the preview release.

The performance gains rely on fine-tuned data compression, allowing the system to keep up to 2GB more active data in memory instead of offloading it to disk storage. Daily interactions such as opening Start, Settings, and File Explorer are up to 20 percent more responsive because background tasks like search indexing now step aside during active use. [1][4]

The focus on lower-memory hardware comes as an ongoing PC component shortage and memory pricing pressures continue to strain hardware specifications. While Microsoft still advises 16GB or more for demanding creative work, it is increasingly positioning 8GB configurations as viable everyday machines. However, industry watchers at PCWorld caution that these operating system tweaks may have limited impact if third-party developers continue to release RAM-heavy, AI-focused software that exceeds lower memory limits.
