Microsoft Optimizes Windows for 8GB PCs, Claiming 40% Faster Multitasking Amid RAM Shortage

Summary
Microsoft said new Windows memory changes make 8GB PCs more usable again, with internal tests showing multitasking completed 40% faster than January 2026 builds.
Up to 2GB of effective RAM comes from heavier compression, while Windows, Edge and Microsoft 365 cut active memory growth by as much as 900MB and preload likely actions more efficiently.
Edge is central to the effort: Microsoft keeps it ready in the background for faster launches, then puts tabs to sleep sooner to reduce memory use once pages are idle.
Intel last week forecast its 2026 CPU sales would fall 10% and said no sustained recovery is expected until memory supply and pricing improve, underscoring why Microsoft is tuning software for scarce RAM.
The broader problem remains unresolved because many apps still demand 8GB or more, and developers adding AI features could erase Microsoft's gains unless the industry also trims memory use.
