Microsoft says Windows 11 performance is up to 20% better in everyday tasks like opening Start, File Explorer, Search and right-click menus, according to its Windows Experience Blog post from October 15, 2026. The gain comes mostly from memory changes, so how much you feel it depends on how much RAM your PC has.
TL;DR: Microsoft claims Windows 11 is up to 20% more responsive, measured by comparing two builds on timed tasks. The biggest lever is keeping up to 2GB more active data in memory, which helps 8GB PCs most. It is a vendor test with no published hardware, so treat 20% as a ceiling, not a promise.
What Microsoft actually measured
The 20% figure is a responsiveness claim, not a benchmark score. Microsoft timed Search, Start, right-click, Settings, Snipping Tool and File Explorer on build 26300.9550 and compared them with build 26200.7628.
The post does not list the test hardware, sample size or how the percentage was calculated. It also says results vary by device, configuration and usage. That is a normal disclaimer, but it means “up to” is doing real work here.
A separate figure covers the new Photos app, which Microsoft says launches up to 20% faster on the same two builds. Faster launches matter most for the apps you open twenty times a day.
| Claim | Microsoft figure | Build tested |
|---|---|---|
| Everyday responsiveness | Up to 20% more responsive | 26300.9550 vs 26200.7628 |
| Photos app launch | Up to 20% faster | 26300.9550 vs 26200.7628 |
| Active data kept in memory | Up to 2GB more | Not stated |
| Widgets memory on 8GB PCs | More than 200 MB freed | 26300.9550 |
| AirPods pairing | Up to 15 seconds faster | 26200.8737 |
Those numbers all come from Microsoft’s own footnotes, so none of them has been independently reproduced yet. Until reviewers run their own timings on real hardware, the table is best read as Microsoft’s stated goal rather than a measured result.
Why memory is the real story
Microsoft says Windows can now keep up to 2GB more of your active data in memory instead of moving it to slower storage. Anyone who has watched a laptop stall after opening a browser, a chat app and a spreadsheet knows that stall is often paging to disk.
The post says this matters most on PCs with 8GB of memory. On those machines, Widgets now load only when opened, which frees more than 200 MB for the apps you are actually using.
That is a consequence worth sitting with. A 16GB desktop will probably see little difference, while an older 8GB laptop could feel noticeably less sticky.
Where Windows 11 performance gains show up first
Microsoft lists Start, File Explorer, Search, Snipping Tool, Microsoft 365 and Edge as places you should feel the change. Right-click menus are on the list too, which is where lag tends to be most irritating because you notice it dozens of times a day.
There are smaller wins outside raw speed. Microsoft says pairing AirPods is up to 15 seconds faster, and that Windows Update offers shorter update times and better coordination to reduce restarts.
The new Search is part of the same push. It adds Actions that change settings like dark mode or night light straight from results, and our earlier look at the Windows Search rebuild covers how that works. It is available to Insiders now, with a wider rollout later this year.
What to check before you expect a faster PC
Microsoft says the changes are beginning to roll out broadly, and that timing and availability vary by device and region. The post does not name a feature update or give a date for most items, so there is no version number to look for yet.
Start by checking how much RAM you have and which version you are on. If you are still on version 24H2, our guide to 24H2 ending security updates explains why updating matters regardless of speed.
The honest read is that 20% is Microsoft grading its own homework. It is a credible direction, since the changes target memory pressure on the machines that struggle most, but the first independent timings will say more than the headline does.
