Microsoft has officially confirmed a Windows 11 weak hardware fix is coming — and for millions of users running budget laptops and ageing desktops, it cannot arrive soon enough. Windows 11 has long been criticised for chewing through RAM on modest machines, leaving 4 GB and 8 GB systems feeling sluggish even during basic tasks. Here is a clear breakdown of what Microsoft has promised, what is already changing, and what you should do in the meantime.
Why Windows 11 Struggles on Budget PCs
Windows 11’s performance problems on entry-level hardware are not accidental — they stem from deliberate design choices. The OS was built around a richer UI framework (WinUI 3), deeper Copilot AI integration, and background telemetry services that collectively consume far more RAM than Windows 10 ever did. Windows 11 idles at roughly 4–5 GB of RAM, compared to approximately 2–3 GB for Windows 10. On a machine with only 4 GB total, that leaves almost nothing for your browser, email client, or productivity apps.
The problem is compounded by how Windows 11 handles memory allocation. Background processes — including widgets, the search index, Copilot components, and the Start menu — keep competing for the same limited pool of resources. On a Windows 11 low-end PC, this means constant disk paging, visible stuttering, and multi-second app launch times that make the experience genuinely painful.
Microsoft’s Official Admission and the Fix Promised
In a significant public acknowledgement, Microsoft confirmed in mid-2025 that Windows 11 is a memory hog on machines with 8 GB RAM or less, and formally committed to delivering meaningful performance improvements by the end of 2026. This is not a vague roadmap item — it is a named engineering priority. The company’s stated goal is to reduce the OS memory footprint so that machines with 8 GB RAM can run Windows 11 comfortably without constant paging, and so that the general responsiveness gap between Windows 10 and Windows 11 closes on modest hardware.
Key areas targeted in the optimisation programme include:
- Reduced idle memory usage — slimming down the baseline OS footprint so more RAM is available for user applications.
- WinUI 3 memory leak fixes — Microsoft has acknowledged that its own native apps (Notepad, Settings, Photos) consume disproportionate RAM due to framework inefficiencies.
- Background process throttling — smarter scheduling so widgets, telemetry, and AI features consume fewer resources on low-RAM devices.
- Faster startup and resume times — particularly targeting the slow boot experience reported on budget SSDs and eMMC storage.
Windows 11 Budget PC Performance: What’s Already Improved
Some wins have already landed. Microsoft’s Windows 11 24H2 update brought incremental Windows 11 budget PC performance improvements, including a leaner Widgets board that no longer runs persistently in the background, and a revised search indexer that pauses more aggressively when system resources are constrained. Users on 8 GB machines have reported marginally snappier app switching after the update, though the improvements are modest rather than transformative.
Microsoft has also introduced a new in-OS notification that flags when low RAM is actively slowing your PC — a feature that debuted quietly in a 2025 Insider Preview build. It does not fix the underlying issue, but it does confirm the company is now treating memory pressure as a first-class user experience problem rather than simply telling users to upgrade their hardware.
Will the Fix Actually Work for 4 GB Machines?
This is where expectations need calibrating. Microsoft’s stated optimisation target is 8 GB RAM — not 4 GB. The official minimum requirement for Windows 11 remains 4 GB, but Microsoft has been candid that Windows 11 RAM optimization efforts are primarily focused on the 8 GB bracket. For users on 4 GB machines, the picture is more complicated.
A 4 GB Windows 11 machine will likely see some benefit from the memory footprint reductions — if the OS idle usage drops from 4.5 GB to 3.5 GB, that genuinely frees up headroom. But the honest answer is that 4 GB remains tight for Windows 11 in any realistic daily-use scenario. If you are running a 4 GB laptop for light tasks — email, document editing, basic web browsing with two or three tabs — an optimised Windows 11 may become tolerable. Gaming, video calls, or anything more demanding will still struggle.
The practical threshold for a smooth Windows 11 experience, even post-fix, is realistically 8 GB. If your machine supports a RAM upgrade, that remains the single highest-impact intervention available to you right now — before Microsoft’s software optimisations are even fully delivered.
What You Can Do Right Now on a Low-End Windows 11 PC
You do not have to wait until 2026. Several practical steps can meaningfully improve Windows 11 low-end PC responsiveness today:
- Disable startup apps — Open Task Manager, go to Startup Apps, and disable everything you do not need at boot. This alone can cut startup RAM usage by 300–600 MB.
- Turn off Widgets — The Widgets board is one of the heaviest background processes on Windows 11. Disable it via Settings > Personalisation > Taskbar.
- Switch to Efficiency mode for background apps — In Task Manager, right-click resource-hungry background processes and select Efficiency Mode to throttle their CPU and memory usage.
- Remove bloatware — Factory pre-installed apps can collectively consume hundreds of megabytes of RAM at idle. Check out our Windows 11 bloatware removal guide for safe, step-by-step instructions using Settings and PowerShell.
- Adjust virtual memory — On machines with slow eMMC storage, manually setting a larger page file on any secondary faster storage can ease RAM pressure during peak load.
- Set Power Mode to Balanced or Best Performance — Budget laptops often default to Power Saver, which throttles the CPU and makes everything feel slower than it needs to be.

Should You Still Upgrade to Windows 11 on a Budget PC?
With Windows 10’s end-of-support date set for October 2025, the question is increasingly not whether to move to Windows 11, but when and how. If your machine meets the official minimum requirements — 1 GHz dual-core processor, 4 GB RAM, 64 GB storage, TPM 2.0, and UEFI Secure Boot — then upgrading is the right long-term move for security alone. Running an unsupported OS exposes you to unpatched vulnerabilities with no recourse.
The good news is that a genuine Windows 11 licence does not have to cost a fortune. Windows 11 Home OEM is available from ShopKeyOnline from just €9.80, with instant email delivery of your activation key and official Microsoft download links included. If you need the added flexibility of a transferable licence, Windows 11 Home Retail is available from €15.65 — still a fraction of the box-price alternative.
For users on budget hardware specifically, the OEM route is the most cost-effective way to get a legitimate, fully activated copy of Windows 11 while you wait for Microsoft’s performance improvements to roll out.
Windows 11 RAM Optimization: The Bigger Picture
Microsoft’s decision to publicly acknowledge the memory problem is strategically significant. The company is under competitive pressure from Chromebook and cloud-thin-client alternatives that run smoothly on 4–8 GB of RAM, and it knows that a bloated OS experience on entry-level hardware is driving users away — or keeping them on Windows 10 past its support deadline.
The optimisation commitment also signals that Windows 11 is maturing. The early post-launch period was characterised by feature additions at the expense of performance; this shift towards resource efficiency suggests Microsoft is now prioritising reliability and responsiveness alongside new features. Whether the improvements by end of 2026 will be dramatic enough to transform a 4 GB machine into a genuinely pleasant Windows 11 experience remains to be seen — but the direction of travel is unambiguously positive.

FAQ: Windows 11 Weak Hardware Fix
Does the Windows 11 performance fix apply to 4 GB RAM machines?
Microsoft’s primary target for its Windows 11 weak hardware fix is 8 GB RAM systems, not 4 GB. That said, reducing the OS’s overall memory footprint will provide some benefit to 4 GB machines. However, 4 GB will remain a tight constraint for everyday use even after the optimisations land. For the best experience, 8 GB RAM is the realistic baseline.
When will Microsoft release the Windows 11 performance improvements?
Microsoft has committed to delivering meaningful Windows 11 RAM optimization improvements by the end of 2026. Some incremental gains have already arrived via the 24H2 update, including a less resource-intensive Widgets board and a smarter search indexer. The most significant changes are expected across 2025 and 2026 updates.
Is Windows 11 faster than Windows 10 on budget PCs?
Currently, Windows 10 is generally faster on low-end hardware. Windows 11’s idle RAM usage (4–5 GB) significantly exceeds Windows 10’s (2–3 GB), making it noticeably slower on machines with 4–8 GB of RAM. The gap is expected to narrow once Microsoft’s Windows 11 budget PC performance optimisations are fully delivered.
What is the minimum RAM needed to run Windows 11 comfortably?
Microsoft’s official minimum is 4 GB, but the practical minimum for a comfortable Windows 11 experience — running a browser, email, and productivity apps simultaneously — is 8 GB. After the planned optimisations, Microsoft expects 8 GB systems to perform well. Until then, 4 GB systems should follow the manual tweaks outlined above to reclaim usable headroom.
Can I get a cheap legitimate Windows 11 licence for my budget PC?
Yes. ShopKeyOnline offers Windows 11 Home OEM keys from €9.80, delivered instantly by email with official Microsoft download links. This is a genuine activation key — not a trial or workaround — and is the most cost-effective way to run a licensed, fully supported copy of Windows 11 on a budget machine.
