If you’re anything like me, nothing tests your patience faster than a slow Windows computer. One minute you’re opening a browser tab, and the next you’re wondering if your laptop has secretly gone on vacation. I’ve been there — more times than I’d like to admit.
The good news? You don’t need to be “techie” to make Windows 10 or 11 run faster. A handful of tweaks can genuinely transform how your PC feels. I’m talking about the kind of speed-up that makes you go, “Wait… this is the same computer?”
Let’s walk through the methods that actually work, without the confusing jargon or risky tricks you see floating around online.
1. Disable Unnecessary Startup Programs
Honestly, this is usually the number one reason Windows feels slow. A lot of apps sneak into your startup list without asking, so your PC ends up loading things you don’t even use.
How to do it:
- Press Ctrl + Shift + Esc to open Task Manager.
- Go to Startup.
- Disable apps you don’t need to launch automatically.
I do this on every new PC. The moment you disable the unnecessary ones, you feel the difference the next time you restart.
2. Uninstall Apps You Don’t Use
You’d be surprised how many useless or forgotten apps slow down your system in the background. If there’s something you installed months ago and never opened again, there’s a good chance it’s doing more harm than good.
Steps:
- Go to Settings → Apps → Installed apps.
- Sort by “Size” or “Install date.”
- Remove anything you no longer need.
I once removed nearly 10 GB worth of stuff I didn’t even remember installing. My PC literally felt lighter afterward.
3. Turn Off Heavy Visual Effects
Windows looks pretty by default — smooth animations, shadows, fades — all that fancy stuff. But looks come at a price. If your machine is older or low on RAM, disabling some effects helps a lot.
Here’s how:
- Right-click This PC → Properties.
- Select Advanced system settings.
- Under Performance, click Settings.
- Choose Adjust for best performance or manually tick/untick items.
Personally, I prefer leaving “Smooth edges of screen fonts” on so text doesn’t look too sharp.
4. Clean Up Temporary Files
Windows collects temporary files like it’s storing memories. Over time, they pile up and slow things down. Clearing them frees space and helps Windows breathe a little.
To clean temp files:
- Open Settings → System → Storage.
- Enable Storage Sense for automatic cleanup.
- Click Temporary files and remove everything you don’t need.
I run Storage Sense monthly, and the difference adds up over time.
5. Update Windows Regularly
I know… updates sometimes feel annoying. But the truth is, Microsoft updates often include performance improvements, bug fixes, and security patches — all of which help your PC run smoother.
You can check updates here:
- Settings → Windows Update.
If an update includes performance improvements, you’ll usually see it in the log. Only download updates from the official Microsoft source at microsoft.com/software-download.
6. Use the Built-In Troubleshooters
One thing I like about Windows 10/11 is that it comes with real, useful troubleshooters. Many people ignore them, but they’ve fixed slowdowns for me multiple times — especially the maintenance and performance troubleshooters.
Try this:
- Open Settings.
- Go to System → Troubleshoot.
- Run Recommended troubleshooters.
They’re simple but surprisingly helpful.
7. Turn Off Background Apps You Don’t Need
Some apps keep running in the background even when you’re not using them. They use RAM, CPU, and sometimes internet bandwidth.
Disable them:
- Go to Settings → Apps → Apps & Features.
- Select the app → Advanced options.
- Turn off Background apps permissions.
I usually set most apps to “Never” unless it’s something important like cloud storage.
8. Free Up Disk Space
If your PC is running out of storage (especially the system drive), it will slow down badly. Windows needs free space to create caches and run services properly.
To free space:
- Delete old downloads.
- Remove duplicate files.
- Empty Recycle Bin.
- Move large files to an external drive or cloud storage.
Keeping your C: drive at least 20% free makes a noticeable difference.
9. Check for Malware
Even one malicious app can slow your PC dramatically. I always recommend scanning with the built-in Windows Security. It’s effective and already built into the system.
To run a scan:
- Open Windows Security.
- Select Virus & threat protection.
- Run a Full scan.
Only download additional antivirus software from an official website if you really need it.
10. Upgrade Your Hardware (If You Can)
Sometimes the problem isn’t Windows — it’s the hardware. I’ve revived extremely slow PCs just by upgrading one or two components.
The two upgrades that bring the biggest improvement:
- SSD (Solid State Drive) – The single best upgrade for speed.
- More RAM – Especially if you have 4GB or less.
If you’re still using a mechanical hard drive, switching to an SSD makes the computer feel brand new. I’ve done this multiple times for friends and family, and the reaction is always the same: “Why didn’t I do this earlier?”
I know how frustrating a slow Windows PC can be. But with a few simple tweaks, you can squeeze out a lot more speed without spending money. And honestly, it’s a nice feeling when your computer finally stops dragging its feet.
If there’s one tip I’d recommend starting with, it’s clearing startup apps. It gives the fastest and most noticeable boost right away. Then work your way through the rest at your own pace. Trust me, your PC will thank you for it.
