Microsoft's 26H2 update for Windows 11 landed at the end of September, and users are noticing something unexpected in Task Manager. Multiple reports suggest meaningful drops in RAM usage after installing the patch — if the claims hold up, this could be a quiet win for anyone running lean hardware.
At a glance
- 26H2 arrived September 29 for PCs running 23H2 or 25H2.
- Reddit users report roughly 2GB of freed RAM, with some seeing up to 3GB.
- One user shared startup RAM dropping from 6.9GB to 4.8GB after install.
- Microsoft has not announced any specific RAM reduction tied to the update.
- Not every user sees a change; some report no difference.
What Microsoft actually shipped
26H2 is a small, security-focused update. It bundles fixes plus a handful of features previously rolling out through monthly patches — no flashy additions here. That said, it arrives during a welcome cleanup phase: September updates restored taskbar and Start menu functionality lost at Windows 11's launch, and desktop customization controls returned. For users who held off on upgrading, the platform is finally reaching the polish many expected at launch.
Why the RAM reports matter
Laptops with under 32GB of RAM are common, and on those machines, every gigabyte counts. Running 20+ Chrome tabs, a messaging app, and background services can push older systems into the red. Freeing 2-3GB of headroom is the difference between smooth tab switching and visible stutter.
For desktop users sitting at 32GB or more, the gain is pleasant but rarely transformative. For anyone on 8GB or 16GB — especially a laptop where you can't swap in another stick — that margin could prevent slowdowns during a video call or while running creative software.
Our analysis: What's really happening
The obvious catch: Microsoft hasn't claimed a memory improvement. This is a user-reported phenomenon, not a documented change. That doesn't make it fake, but the cause remains unconfirmed. Possible explanations include a background service being trimmed, a memory leak patched, or even users simply paying closer attention to Task Manager post-update.
There's also a placebo factor. People who just refreshed their OS are primed to notice improvements. The honest test requires discipline: same startup apps, same workload, same settling time after each restart.
The trade-off is asymmetric. The downside of installing is negligible — you're getting security patches either way. The upside, if real, is free performance. That's worth a measured test, not blind faith.
Who should care
| User type | Verdict |
|---|---|
| Laptop users on 8GB/16GB RAM | Strong yes — even a 1-2GB gain meaningfully changes daily workflow |
| Desktop users on 32GB+ | Low stakes — nice if it happens, don't plan around it |
| Power users with RAM-heavy workflows | Test it, but don't restructure your workflow based on reports |
| Anyone skipping the update | Security patches alone justify installing — treat RAM gains as a bonus |
A practical test you can run tonight
Before installing, open Task Manager, sort by Memory, and screenshot the top offenders plus the total in use. After updating to 26H2, give the system a day to settle, then check the same numbers under identical conditions.
Real drop: you got a free upgrade. No change: the security patches alone made it worth installing.
How to get 26H2
Head to Settings > Windows Update and toggle on automatic update delivery. If 26H2 doesn't surface right away, your device may still be queued for rollout — check back in a few days.
What to watch next
- Whether Microsoft acknowledges the RAM improvement or stays silent.
- Memory-related fixes in the next cumulative update.
- Benchmark comparisons from tech channels across more hardware configurations.
- Regression reports — lower RAM usage can sometimes mean a feature got disabled rather than optimized.
Bottom line
Treat the RAM reports as promising but unconfirmed — the security fixes are guaranteed either way. Install 26H2, measure honestly, and don't expect miracles if your bottleneck is actually the CPU or the disk.
Key takeaways
- 26H2 shipped September 29 as a small, security-focused update.
- Multiple users report 2-3GB of RAM freed after installation.
- Microsoft has not officially claimed a memory improvement — treat reports as promising but unconfirmed.
- The update is worth installing regardless; RAM gains are a potential bonus, not a promise.
