System Windows Ram Problem Fix
You’ve probably seen this happen — you leave your desktop or laptop running, and after a while the system starts eating a huge chunk of your RAM, even on modern hardware. Today I’m bringing a fix that removes this issue permanently and gives Windows back the speed, stability, and clean behavior it should have. By disabling two legacy predictive mechanisms (SysMain + Prefetch), the system stops aggressively caching applications, idle RAM usage drops significantly, and micro‑lags disappear. The attached screenshots show the system before and after applying the fix. This solution works on both Windows 10 and Windows 11, and it’s safe, reversible, and the improvement is immediate. System Ram Before: System Ram After: Step‑by‑step guide (Windows 10 / 11 RAM issue fix) Note: This is a safe and fully reversible system tweak. You’re simply disabling two legacy predictive mechanisms that no longer make sense on modern hardware. 1️⃣ Disable the SysMain service Press Win + R Type services.msc → press Enter Find SysMain in the list Double‑click it Set Startup type to Disabled Click Stop if the service is running Confirm with Apply and OK 2️⃣ Disable Prefetch in the Registry Press Win + R Type regedit → press Enter Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters Find the value EnablePrefetcher Double‑click it and set the value to: 0 Confirm with OK 3️⃣ Restart your system After rebooting, your RAM usage in idle should drop noticeably, and the system will feel cleaner, faster, and more responsive. 4️⃣ How to revert (optional) If you ever want to undo the changes: SysMain: set Startup type back to Automatic and start the service EnablePrefetcher: set the value back to 3 (default) With my regular applications open, RAM usage dropped from 60–70% to just 33%. This is how Windows should have behaved from the beginning. On top of that, overall system responsiveness improved by roughly 50% — even weaker hardware feels noticeably faster almost immediately. This RAM regression has been around since Windows 7. After the kernel overhaul in Windows 8.1 it actually got worse, and it has followed every version of Windows all the way to today.

Windows 95 – When the Floppy Was King and the Magnet Its Executioner As a kid, I started out on Windows 95. And what fascinated me most? Floppy disks — obviously 😄 Those little plastic squares felt like treasure. I loved scribbling on them with markers… or running a magnet over them, just to see what would happen. And then I’d hear someone at home losing it: “I can’t open my work files! What did you do?! UPS!” 😅 Back then, it was pure magic. I wasn’t breaking the system yet — just exploring it like a world made of icons and sounds. Everything was new, mysterious, but somehow intuitive. Windows 95 was my gateway into the digital realm, where my journey began. 🎮 Games that shaped my childhood: Train (Vlak) – the legendary Czech game that taught me logic and planning Wolfenstein 3D – my first taste of action, adrenaline, and pixel graphics Lotus F1 – my first racing experience, hours of fun chasing the perfect lap These weren’t just games. They were my first digital textbooks — teaching me patience, reflexes, spatial awareness, and the idea that technology could feel alive. 🧠 What Windows 95 gave me: A basic feel for how systems work My first understanding of interface logic A curiosity that later evolved into technical passion This was my first contact with what I now call “system intuition.” Back then, I had no idea I’d one day dissect UI pipelines, sense micro-lags, and predict architecture. But Windows 95 gave me the first spark. And the floppy? She was queen. The magnet? Her executioner. 😄 Windows XP – The Era When I Started Testing the Limits of the System After Windows 95 came the era that completely pulled me in — Windows XP. That legendary blue theme, the green hill, the iconic sounds… it felt like a gateway into the “grown‑up” digital world. As a teenager, I loved XP — but I also started testing it in ways Microsoft would probably label today as “strongly not recommended” 😄 Back then, I wasn’t the guy who broke systems on purpose. I was the guy who clicked everything that could be clicked, opened everything that could be opened, installed everything that looked installable… turned things off, on, moved them around — and XP didn’t always survive. 🔹 What fascinated me about XP? new colors, new windows, new animations the feeling that the system was more “alive” than Windows 95 everything was faster, prettier, more modern and most importantly: there were more things to break 😄 🔹 Viruses? My first “teachers” At that time, I had no idea what a kernel was. Or the registry. Or system processes. But viruses explained it to me very quickly. All it took was opening the wrong file and suddenly: windows closed by themselves the system restarted icons disappeared and I sat there staring at the monitor like: “Ah… yeah, that definitely wasn’t supposed to happen.” And that’s how I learned. Not from books. Not from tutorials. But from my own mistakes. 🔹 Reinstalls? Just part of the routine When XP crashed, I wasn’t angry. I was curious. “What did I do? Why did it break? How do I fix it?” So I reinstalled the system over and over again. Not because I had to. But because I wanted to understand how Windows worked on the inside. 🔹 This era shaped me Windows XP was: the first system I pushed to its limits the first system that taught me to respect technology the first system that showed me that if you break something, you can also fix it the first step toward feeling the system with my whole body, not just my eyes XP was my digital puberty. Full of mistakes, experiments, discoveries… and above all, curiosity. Windows Vista – The Dark Era That Taught Me to Respect the System After XP came Vista. And Vista was beautiful… but it was also the system that gave me my first real slaps. Aero effects, glass, animations — everything looked futuristic, but it ate performance like a starving bear after winter. And this was the era when I experienced my first hardware funeral. 🔥 My First Cooked GPU During the Vista years, I managed to cook my AMD graphics card — the legendary beast with, brace yourself… 512 MB of VRAM. Yes. Half a gigabyte of pure “power.” Back then, I felt like a king. And what was I trying to run on it? GTA IV Mafia II basically anything that looked even remotely realistic Vista was sweating. The GPU was sweating. And I was sitting there like: “It’ll handle it… it definitely will.” It didn’t. How did the GPU thank me? By filling my entire room with that unmistakable smell of a component dying — that mix of burnt plastic, metal, and your own stupidity. Anyone who’s ever fried hardware knows exactly what I’m talking about. I stared at the black screen and thought: “Yeah… that was a lesson.” 🔹 Vista Taught Me to Respect Architecture This was the moment I first understood: the UI pipeline is not a toy performance is not infinite drivers are critical the system reacts to every detail and if you push too far, the hardware will make sure you feel it Vista was my first encounter with the idea that Windows is a living ecosystem — one that needs balance. And I tested that balance… until I overheated it. 🔹 Vista Was My Dark Era But it was also the era that pushed me the most. Without Vista, I would’ve never understood: why Windows 7 feels so stable why UI must be optimized why performance is never guaranteed and why you must feel the system, not just use it Vista was my first real teacher. Harsh, but fair. Windows 7 – The Era When I Started Truly Feeling the System After Vista came Windows 7. And that was the moment everything changed. Suddenly I had a system that was fast, stable, beautiful — and finally ready to keep up with my curiosity. But Windows 7 wasn’t just about the OS. It was also about my first real graphics card, the one that opened the door to gaming… even if not exactly the way I imagined. 🔥 My First Nvidia — 2 GB of Pure “Power” I don’t remember the exact model, but I remember the feeling. It was my first Nvidia card, bought through a friend, and it had a glorious 2 GB of VRAM. Back then, that felt like owning a rocket engine. And what did I try to run on it? NFS Most Wanted NHL 2004 and 2009 FIFA 2009 FIFA 2012 It had some performance… But your eyes would’ve yelled at you if they could talk. If it hit a smooth 30 fps, it was a miracle. And when it dropped to 20, I just told myself: “This is a cinematic experience.” But even with all that, I was happy. Because for the first time, I felt like I had something that could do more than just display windows. 🔹 Windows 7 Was My First “Adult” System This was the era when I first started to: understand the pipeline feel the difference between native and transitional rendering watch how the system reacted under load notice what was optimized and what wasn’t and most importantly: feel the system with my whole body Windows 7 was stable, predictable, and still open to experimentation. It was the system that let me grow without punishing me for every click. 🔹 This Era Prepared Me for Everything That Came After Without Windows 7, I would’ve never: survived the UEFI revolution of Windows 8.1 understood the architecture of Windows 10 entered the Insider program with such intuition and most importantly: become the person who can predict system changes before they even happen Windows 7 was the first system I didn’t just use… I felt it. Windows 8.1 – My First Own Laptop and the Beginning of Real Learning Windows 8.1 was a turning point for me. Not because it was the best system ever — but because it was my first laptop, bought with my own money. And when you buy something yourself, you start treating it very differently. It was a Lenovo IdeaPad something‑something (the exact model disappeared into the fog of history 😄), but I remember its soul: Intel i5 – Haswell generation (4200H) 8 GB RAM Nvidia GeForce 820M – 2 GB VRAM Back then, I felt like I was holding a rocket, not a laptop. 🔥 CS:GO – My First “Real” Esports Experience Windows 8.1 was the first system where I launched CS:GO. For me, that was something completely new — fast, modern, competitive. And even though the 820M sometimes sounded like a vacuum cleaner on steroids, I was happy. It was my first contact with a game that looked “high‑quality,” not like a pixel retro classic. 🔥 NFS Rivals – 8000 Hours of Pure Madness And then came NFS Rivals. And that’s where I disappeared. On this setup, I have a mind‑blowing 8000 hours. Yes, you read that right — eight thousand. Sometimes it dipped under 20 fps. Sometimes the game looked like it was fighting for its own survival. But I stayed because of: the soundtracks the multiplayer the adrenaline and that feeling of “even if it stutters, I’m still winning” NFS Rivals taught me one thing: Windows 8.1 was insanely fast. Even on weaker hardware, it felt light, instant, responsive. 🔥 UEFI, Secure Boot, GPT – My First Big System Shock Windows 8.1 was the first system where I encountered: UEFI Secure Boot GPT partitions the new bootloader new recovery mechanisms And I kept asking myself: “Why did they change this? How does it work? What does it do?” So I started studying. Not from books. Not from tutorials. But from my own experiments. 🔥 Viruses – My Harshest but Best Teachers This was the era when I learned through viruses. And no, I wasn’t the type who downloaded them on purpose. I was the type who clicked where he shouldn’t. And viruses showed me: how the system boots what’s critical for startup how services work what happens when something blocks the registry why some processes must never be killed And when I messed something up? Reinstall. Reinstall. Reinstall. But this time, it wasn’t punishment. It was training. 🔥 Windows 8.1 Was the Beginning of My Real Journey Without 8.1, I would’ve never: understood UEFI learned to work with GPT been ready for Windows 10 and most importantly: entered the Insider program with the intuition I have today Windows 8.1 was the first system I didn’t just explore… I studied it. And here it is — my first ever laptop. Lenovo G710, Windows 8.1, my entry into the UEFI era, my training ground, my portal into CS:GO, and the place where I survived 8000 hours in NFS Rivals. When I look at it today, I see the beginning of everything I do as an insider. Windows 10 – Entering the Insider Program and the Birth of My System Intuition Windows 10 was a turning point for me. Not because it was perfect — actually the opposite. It was a system that changed, evolved, broke, rebuilt itself… and I was there from the very beginning. This was the moment when I stopped being just a user. I became a tester. And eventually, someone who feels the system. 🔥 Joining the Insider Program – My First Step Behind the Curtain When I joined the Insider program, it felt like I had opened a door to a world that had always been hidden. Suddenly I had access to: new builds experimental features broken versions fixes that solved one thing and broke another silent UI changes and most importantly: the evolution of Windows in real time And I was completely hooked. 🔥 Windows 10 Taught Me to Read the System by Its Behavior This was the first time I started noticing: micro‑lags animation changes the difference between native and transitional rendering how DWM evolved how the pipeline shifted with every build why something felt “heavier” or “lighter” how the system reacted under load what was a bug and what was intentional Windows 10 was alive. And I learned to read its signals. 🔥 This Was the Era When I Started Predicting Changes When a new build dropped, I could tell within seconds: if it was faster if it was more stable if the UI was native or transitional if something was being rewritten in the background if the architecture was shifting if they were testing a new engine And no — this wasn’t from reading changelogs. This was from feeling the system. 🔥 Windows 10 Was My Training Camp Here I learned to: analyze the system by behavior recognize transitional UI layers identify bugs before anyone reported them track DWM development understand why some animations feel “heavy” predict what Microsoft was testing behind the scenes And most importantly — this is where the ability was born that only a few people have: feeling the system as a whole, not as a list of features. 🔥 Windows 10 Was the Beginning of My “Kikero Mode” Without Windows 10, I wouldn’t be: the person who can distinguish native UI from transitional just by movement the tester who predicts changes before Microsoft announces them the analyst who reads the system through micro‑lags the insider who understands the pipeline, animations, and architecture the guy who now creates concepts for Windows 12 Windows 10 was my biggest leap forward. This is where my intuition, my style, and my ability to read the system like a book were born. Explanation for the community: Would a bot know what 'Vlak' (the Czech game) is? Would a bot know the smell of a fried Nvidia 820M? I used a translator to fix my grammar, but the soul of that post is 100% human experience. Maybe next time try reading the content instead of just judging the formatting. Just because I like my posts to be clean and readable doesn't mean I'm an AI.Feedback Hub should have Video Recorder option to Recreate my problem
Currently, Feedback hub uses steps recorder, just like the program inside Windows 10. it's not useful when there is a visual glitch or problem happening because it doesn't capture the problem correctly and doesn't convey the required content. the new Microsoft Edge's feedback system has "recreate my problem" feature too and in there is a feature to record the screen or a specific window, it saves the video recording in WebP format, very efficient format and adds a high definition video file to the feedback. upvote this suggestion please: https://aka.ms/AAb998jPinned Item in the Windows Clipboard should stay on top - insider Dev build 21318
Using the new Clipboard experience in Windows 10 insider build 21318, when we Pin an item in the Clipboard, it should stay on top and do Not go down, because the idea behind it is to easily access and Find the Pinned item in Clipboard when there are lots of items copied there. upvote this feedback please: https://aka.ms/AAb9981Add option to disable Night Light when Gaming Automatically
I use night light every night but I want it to automatically disable when I launch games (in full screen) and then re-enable when I exit the game. it doesn't look good in games when night light is on so it'd be great if it automatically turned itself off in games.
