Windows 11 8GB RAM PCs are getting a memory tune-up. Microsoft says its latest work lets Windows keep up to 2GB more active data in RAM and load Widgets only when you open them. The catch is that early testing shows clear gains on 16GB laptops and none yet on an 8GB one.
Here is the short version before we get into the details:
- Microsoft announced the changes on October 15, 2026, in a Windows Experience Blog post.
- It claims up to 2GB more active data can stay in RAM, and everyday tasks feel up to 20% faster.
- On PCs with 8GB of RAM or less, Widgets now load on demand, freeing more than 200MB.
- The figures come from build 26300.9550, and Microsoft hasn’t given a full rollout date.
- You don’t need to change any setting to get the memory improvements.
That list is the whole announcement in miniature. The rest of this post covers what each claim really means for your PC.
What Microsoft changed on Windows 11 8GB RAM PCs
According to The Next Web, Corporate VP Navjot Virk laid out the work in a Microsoft blog post. It follows an earlier promise from Pavan Davuluri to make Windows lighter on 8GB machines.
The changes sit in the way Windows manages memory. Windows can now hold more of the data you are actually using in RAM instead of pushing it out to slower storage. That should mean fewer small stalls when you open Search, move around Start, or browse folders in File Explorer.
Microsoft also says some background features now use less memory, though it hasn’t named them all. The one it does name is Widgets, which on 8GB PCs now load only when you open the panel. That frees more than 200MB for your apps.
Does “2GB more” mean you get 2GB of free memory?
Not quite. As Pureinfotech points out, this is extra data that can stay in memory, not a 2GB cut in total RAM use. Think of it as a bigger desk: more of your working papers stay in reach, but the desk is not emptier.
Microsoft also calls 2GB the maximum. Guru3D notes the company didn’t break down where that figure comes from or promise it for every PC.
Your result will depend on what you run. A machine with a few apps open may barely notice. One juggling dozens of browser tabs and Teams could feel the difference more.
What the early tests show about Windows 11 8GB RAM gains
This is where the story gets more careful. The Next Web reports that the only hands-on test it found came from Windows Latest. A 16GB laptop used about 2GB less memory, but an 8GB PC showed no change and stayed at 96% memory use.
The 20% figure needs context too. Microsoft compared build 26300.9550 with the older build 26200.7628. It timed Search, Start, the right-click menu, Settings, Snipping Tool, and File Explorer. None of those is a memory test.
This table sets each claim next to the fine print:
| Claim | Microsoft’s number | Fine print |
|---|---|---|
| Active data kept in RAM | Up to 2GB more | Maximum figure; not a drop in total RAM use |
| Responsiveness | Up to 20% better | Based on timed interface tasks across two builds |
| Widgets on 8GB or less | 200MB+ freed | Widgets load only when you open them |
| Independent test (16GB laptop) | About 2GB less memory used | Reported by Windows Latest, via The Next Web |
| Independent test (8GB PC) | No change | Memory use stayed at 96% |
The point of the table: the headline numbers are real claims, but they are Microsoft’s own, and the one 8GB test so far didn’t back them up. More testing should settle it.
How to check your memory use and get the update
Microsoft hasn’t published a full schedule. gHacks says the improvements are beginning to roll out broadly, but it adds no date. Until yours arrives, you can measure a baseline.
These steps show how much memory your PC uses today:
- Press Ctrl+Shift+Esc to open Task Manager.
- Open the Performance tab and select Memory.
- Note the “In use” and “Available” numbers after a normal hour of work.
- Check again after the next Windows 11 update installs.
A before-and-after comparison tells you more than any benchmark claim. To check for the update, open Settings, go to Windows Update, and select Check for updates.

Frequently Asked Questions
Is 8GB of RAM enough for Windows 11?
It runs fine for browsing, email, and office work. It gets tight with many tabs and chat apps open, which is why Microsoft is trimming background memory use.
Will this Windows 11 update speed up my old laptop?
Maybe, but not by a promised amount. Microsoft says up to 20%, yet that is a best case from selected tasks, and one early 8GB test showed no change.
Do I need to change a setting to get the memory improvements?
No. Per gHacks, no setting change is needed for the memory and responsiveness work. It arrives through Windows updates.
Which build has these changes?
Microsoft’s comparison used build 26300.9550. It hasn’t said which release channel each build belongs to or when all PCs will get it.
Our take: promising, but wait for proof
If you run Windows 11 on 8GB, keep your expectations modest and take your own Task Manager numbers before and after the update. Fewer background hogs is welcome news, and Widgets on demand is a clear win. But until independent tests show real gains on 8GB hardware, treat the 20% figure as a best case, not a promise. If your PC still struggles, a RAM upgrade or a 16GB machine remains the surer fix.
