Getting your Windows 11 machine to use less memory can feel a bit overwhelming at first, especially if your PC starts stuttering or running out of RAM when you’ve got a bunch of apps open. The good news is, most of the fixes are pretty straightforward — no need to be a tech whiz — but sometimes Windows likes to throw a tantrum. This guide aims to cut through the clutter and give you some handy tips to help your PC run smoother, faster, and respond a bit better by managing and tuning its memory. Once you get the hang of it, you’ll hopefully notice fewer flickers, smoother multitasking, and maybe even a touch more battery life.
How to Reduce Memory Usage in Windows 11
Managing your memory isn’t just about fiddling with fancy settings — it’s more about controlling what’s hogging resources. Usually, it’s as simple as shutting down unnecessary apps, tweaking some settings, and keeping an eye on what’s running in the background. Sometimes, Windows is doing stuff you don’t really need — like keeping apps open for no good reason or letting background processes go nuts. Here’s how to take the reins and keep things in check.
Manage processes with Task Manager
Hit Ctrl + Shift + Esc to bring up Task Manager — honestly, it’s the first port of call. Here, you’ll see all the processes gobbling up your RAM. Some apps can get a bit out of hand, especially if you’ve got a heap of Chrome tabs or background apps running. If you spot something strange or just unnecessary, right-click it and pick “End Task.” That can free up some RAM straight away. Just be careful — avoid ending critical Windows processes like explorer.exe or svchost.exe unless you’re sure what you’re doing. Sometimes, apps misbehave, and you might need to do a bit of detective work to sort them out.
Disable non-essential startup apps
Head over to the “Startup” tab in Task Manager. I’ve been there, waiting for Windows to load, wondering why my PC feels like it’s crawling. Turning off programs that don’t need to start straight away can make a big difference. Right-click on things like Spotify, Dropbox, or updater tools you don’t use right off the bat and hit “Disable.” This cuts down on background processes that keep using memory even when you’re not actively using them. Sometimes, you’ll need to restart your PC to see the changes, but it’s worth it.
Set virtual memory manually
Ever wonder why Windows always suggests letting it handle virtual memory? Sometimes, though, tweaking those settings yourself can help. Go to Settings > System > About > Advanced system settings — that small link at the bottom right of the “About” window opens the classic System Properties. Click “Settings” under “Performance,” then go to the “Advanced” tab, and find Virtual Memory. Make sure “Automatically manage paging file size for all drives” is checked — that’s the best bet. If things still feel sluggish, you can try setting a custom size, but only if you know what you’re doing. Usually, letting Windows handle it is fine, but on some rigs, a tiny tweak can help prevent sluggishness caused by low virtual memory.
Close background apps you don’t need
Head to Settings > Privacy > Background apps, and switch off the ones you don’t really need running in the background. Ever noticed some apps stubbornly keep running even after you’ve closed their windows? That’s pretty normal in Windows 11. Turning off unnecessary background apps frees up memory and CPU cycles — especially good for resource-hungry apps like mail clients, chat programs, or Windows update processes. Sometimes, these settings can reset after an update or fresh install, so it’s good to check occasionally.
Leverage Storage Sense for cleanup
Storage Sense is like having a tidy mate for your PC. Enable it in Settings > System > Storage. Turn on “Storage Sense,” and set it to run automatically or whenever you feel like it. It clears out temporary files, old cache, and stuff in your recycle bin, helping your machine breathe a bit easier. While it’s not a direct memory cleaner, clutter can slow things down over time. Additionally, manually clearing temp files via disk cleanup or using third-party tools can give your system a bit of a boost.
After adjusting these options, your PC should feel a notch snappier — or at least behave more reliably. One thing I’ve found: a quick reboot after changing settings or ending unwanted tasks can make a real difference in freeing up memory. Windows can sometimes be lazy, holding onto processes or cache you don’t need anymore.
Tips for Reducing Memory Usage in Windows 11
- Keep Windows up to date — updates often include better memory management and bug fixes.
- Close or limit the number of browser tabs — they love to gobble RAM.
- Choose a lightweight antivirus if you can — bloatware can chew up resources.
- Reboot your PC every now and then, especially after big updates or new installs.
- Run the built-in Windows Troubleshooter if your system’s acting up — it’s pretty good at sniffing out issues.
Frequently Asked Questions
How do I see which apps use the most memory?
Check out the “Processes” tab in Task Manager. Sorted by memory, it shows you what’s eating up your resources — sometimes, it’s a bit of a shock.
Is disabling startup programs safe?
Mostly, yes. Just avoid turning off critical stuff — like your graphics driver or security software. If unsure, a quick Google of the app can save you headaches.
What exactly is virtual memory anyway?
It’s Windows’ way of using your hard drive as extra RAM when your actual RAM’s full. It’s not as quick as real RAM, but it helps keep your system from crashing or slowing down too much.
How often should I restart to help performance?
Once a week usually does the trick. It clears out caches and resets background tasks that might be hogging resources.
Can I just end any process in Task Manager?
Nope. Only end the processes you recognise and are sure are safe to shut down. Killing critical Windows processes can cause crashes or other issues.
Summary
- Open Task Manager and spot the memory hogs.
- Disable unnecessary startup apps.
- Adjust your virtual memory if needed.
- Close background apps you don’t need.
- Run Storage Sense now and then.
Wrap-up
Getting Windows 11 to use less memory isn’t rocket science, but it can take a bit of poking around in the settings and some trial and error. Usually, a mix of shutting down background apps, disabling auto-starts, and letting Windows handle virtual memory does the trick. It’s pretty satisfying when your PC feels snappier after a few tweaks — like it’s had a shot of adrenaline. Just remember, Windows can be a bit quirky about resource management, so don’t get too annoyed if it takes a few goes to get everything running sweetly. Hope this helps someone squeeze a bit more life out of their system — works for me, every time.
