Windows 11 Performance Update: Up to 40% Faster Multitasking on 8GB PCs

What happened

Microsoft has rolled out a set of performance optimisations to Windows 11 that it says make the operating system significantly faster on PCs with as little as 8GB of RAM. In the company's own tests, responsiveness has improved by up to 20%, and multitasking is up to 40% faster.

The central change is a more efficient memory compression technique that keeps up to 2GB of active data in RAM rather than moving it to slower storage. Microsoft also says the Start menu, search, Settings and File Explorer are up to 20% faster than they were in January 2026, according to a company blog post.

Microsoft's own applications are part of the update. Edge can launch up to 33% faster and Teams can open up to 20% faster. Memory use across Windows, Edge and Microsoft 365 has fallen by up to 900MB, with Word, Excel, PowerPoint and Outlook accounting for about 360MB of that saving.

Why it matters

For organisations running fleets of mid-range hardware, this points to software efficiency as a lever for getting more out of existing devices. Gains of this kind can defer hardware refresh cycles, though the extent of that benefit will depend on each estate's specifications and workloads.

For experience leaders, perceived speed is a service-quality signal. Delays when launching applications, opening search or switching between tasks shape how people judge their tools long before they assess individual features. Because the gains are "up to" figures measured under Microsoft's test conditions, teams should expect real-world results to vary with hardware, workload and installed software.

By the numbers

• Up to 40% faster multitasking on Windows 11 PCs with 8GB of RAM, according to Microsoft's own tests
• Up to 20% improvement in responsiveness, and up to 20% faster Start menu, search, Settings and File Explorer compared with January 2026
• Up to 33% faster Edge launch, and up to 20% faster Teams open
• Up to 900MB less memory across Windows, Edge and Microsoft 365, with about 360MB from Word, Excel, PowerPoint and Outlook

The Renascence take

Most coverage will lead with the 40% headline, but the more instructive figure is the memory reduction. On constrained devices, memory pressure is what quietly erodes the experience, and it is easy to overlook because it rarely appears in a feature list.

Most readers will fixate on the 40% multitasking claim, but the 900MB memory reduction is the figure that matters for daily use, because memory pressure is what degrades responsiveness on modest hardware. The underlying principle is that perceived performance is set in the first moments of interaction, so the time it takes to respond at the point of intent matters more than peak benchmark scores. A customer-obsessed operator should baseline response times across its own device fleet before and after updating, and treat speed as a measured experience metric rather than accepting a vendor's "up to" figure.
