Windows 11 burns through 6GB of idle RAM — Microsoft promises a fix by year-end
If your Windows 11 laptop feels sluggish before you've even opened an app, there's a reason: the OS currently consumes roughly 6GB of RAM at idle on an 8GB machine, leaving almost nothing for actual work. Microsoft has now publicly acknowledged the problem and says a fix is coming — though the timeline is vague and no hard numbers have been published.
At IFA 2026, Microsoft Corporate VP Mark Linton confirmed that optimizing Windows 11 for 8GB systems is a current engineering priority. The targets are specific: faster boot times, a snappier lock screen, and quicker Windows Hello authentication. Internal benchmarks already show meaningful gains, according to Windows Latest, but no public Insider Preview build carries these changes yet.

Why 8GB again?
A global DRAM shortage — with no relief forecast before late 2027 — is forcing PC makers to ship more machines with 8GB as the default configuration. BetaNews reports US PC shipments fell 11.3% in 2026 partly because of the memory crunch. At the same time, Apple's 8GB MacBook consistently outperforms comparable Windows laptops in stress tests, giving Microsoft an additional incentive to close the gap.
The announcement also contradicts months of Microsoft messaging around Copilot+ PCs, which pushed 16GB or 32GB as the practical minimum for AI features. The company's own 8GB Surface Laptop at $1,299 now looks like a quiet admission that the high-RAM push hasn't landed.
Three fixes in the works
Engineers are concentrating on three areas, per Notebookcheck: a more efficient memory allocator, WinUI 3 tuning, and reduced WebView2/Chromium overhead — the browser engine embedded throughout Windows that tests have identified as a major culprit.
The rollout plan is Insider Preview builds first, then standard Windows Update, targeting end of 2026. That's a narrow window, and Microsoft has shared no specific memory-footprint reduction targets. For now, the promise is real but the proof is still internal.
