My Laptop Was Crawling on Windows 11 — These 11 Fixes Made It Fast Again

Clicking an app and waiting… and waiting. A laptop running slow on Windows 11 is one of the most frustrating tech problems because it hits everything: work, school, games and even simple browsing. The good news is that most slowdowns come from software clutter, heat or power settings, and you can fix them yourself in under an hour.

Below are the fixes I use on every slow laptop I set up, ordered from quickest to most involved. If high CPU usage is your main symptom, also read my focused guide on how to fix high CPU usage in Windows 11.

Why Windows 11 Laptops Slow Down

• Too many startup apps loading the moment you sign in.
• Low disk space, which leaves no room for updates and temporary files.
• Heat, which forces the processor to throttle its speed.
• Power settings set to save energy instead of performance.
• Outdated drivers or a half-finished Windows update.
• Not enough RAM for modern browsers and apps.

11 Fixes for a Laptop Running Slow on Windows 11

1. Restart Properly

Windows “Fast Startup” means shutting down doesn’t fully clear memory. Choose Restart instead. It’s simple, but it clears stuck processes and finishes pending updates.

2. Disable Startup Apps

Press Ctrl + Shift + Esc to open Task Manager, then go to Startup apps. Disable anything with “High” impact that you don’t need right away, such as game launchers, chat apps and updaters.

3. Install Windows and Driver Updates

Go to Settings > Windows Update and install everything, including Advanced options > Optional updates for drivers. Microsoft’s own tips to improve PC performance in Windows list updates as the first step for a reason.

4. Free Up Disk Space

Try to keep at least 15–20% of your drive free. Turn on Storage Sense and remove large unused files. Microsoft’s free up drive space guide lists the built-in tools. My full guide on freeing up disk space on Windows 11 shows exactly where hidden gigabytes hide.

5. Switch the Power Mode

Open Settings > System > Power & battery and set Power mode to “Best performance” when plugged in. Keep “Balanced” on battery.

6. Turn Off Visual Effects

Search “Adjust the appearance and performance of Windows,” then choose Adjust for best performance. Older laptops feel noticeably snappier.

7. Uninstall Bloatware

Many laptops ship with trial antivirus, game bundles and brand utilities. Remove what you don’t use from Settings > Apps > Installed apps.

8. Scan for Malware

Run a full scan in Windows Security > Virus & threat protection. Hidden miners and adware are a common cause of sudden slowness.

9. Limit Browser Tabs and Extensions

Chrome and Edge can use several gigabytes of RAM. Turn on sleeping tabs and remove extensions you don’t recognize.

10. Upgrade to an SSD or More RAM

If your laptop still uses a hard drive (HDD), swapping to an SSD is the single biggest speed upgrade you can make. Moving from 8GB to 16GB of RAM also helps if you multitask heavily.

11. Reset Windows as a Last Resort

Use Settings > System > Recovery > Reset this PC and choose “Keep my files.” Back up first.

Laptop Overheating While Gaming? Heat Is the Hidden Slowdown

When a laptop overheats while gaming, the CPU and GPU drop their clock speeds to protect themselves. Your frame rate falls and the whole system feels slow. To keep temperatures down:

• Play on a hard, flat surface, never a bed or lap.
• Use a laptop stand or cooling pad to lift the base.
• Clean dust from vents with short bursts of compressed air.
• Cap your frame rate in game settings to reduce load.
• Use your brand’s performance app (such as Armoury Crate or Vantage) to pick a cooling profile.

How to Fix Laptop Fan Noise

Loud fans are a symptom, not the disease. To fix laptop fan noise, reduce the heat and the background load:

1. Check Task Manager for apps using high CPU while you’re idle.
2. Clean the vents and fan intake.
3. Switch to a quieter or “silent” fan profile in your laptop’s control app.
4. If you hear grinding or clicking, the fan bearing may be failing and needs replacement.

How to Increase Laptop Battery Life

Speed and battery are linked: the fewer things running, the longer your charge lasts. To increase laptop battery life:

• Turn on Energy saver when unplugged.
• Lower screen brightness and refresh rate on battery.
• Close background apps like cloud sync during travel.
• Turn off keyboard backlighting when you don’t need it.
• Use your manufacturer’s battery charge limit (often 80%) if you’re usually plugged in.

Many of these ideas mirror phone tips in my guide on how to improve phone battery life.

How to Check Laptop Battery Health

Want to know if the battery is worn out? Here’s how to check laptop battery health in Windows 11:

1. Right-click Start and open Terminal.
2. Type powercfg /batteryreport and press Enter.
3. Open the HTML report saved in your user folder.
4. Compare Design Capacity with Full Charge Capacity.

If full charge capacity is below roughly 70% of the design value, a new battery will make a real difference.

Laptop Keyboard Not Working on Windows 11

If your laptop keyboard is not working on Windows 11, try these steps:

• Restart the laptop and test the keyboard in the BIOS. If it works there, the issue is software.
• Turn off Filter Keys under Settings > Accessibility > Keyboard.
• In Device Manager, uninstall the keyboard driver and restart so Windows reinstalls it.
• Check for spills or stuck keys if only some keys fail.

Laptop Not Detecting a Second Monitor

When a laptop isn’t detecting a second monitor, check the basics first: cable, input source on the monitor and port type. Then:

• Press Windows + P and choose “Extend.”
• Go to Settings > System > Display and click Detect.
• Update your graphics driver.
• If you use a USB-C hub, make sure the port supports DisplayPort output.

Windows 11 Black Screen After Startup

A Windows 11 black screen after startup is scary but often easy to fix:

1. Press Windows + Ctrl + Shift + B to restart the graphics driver.
2. Press Ctrl + Alt + Del; if the menu appears, open Task Manager and run explorer.exe.
3. Disconnect external monitors and docks, then reboot.
4. Boot into Safe Mode and roll back a recent graphics driver.

Quick Checklist: Weekly Maintenance for a Fast Laptop

• Restart at least once a week instead of only sleeping.
• Check Task Manager’s Startup tab after installing new software.
• Keep 20% of your drive free.
• Install Windows and driver updates as they arrive.
• Blow dust out of the vents every few months.

Five minutes a week keeps most Windows 11 laptops running like the day you bought them.

Final Thoughts

A slow Windows 11 laptop is rarely a lost cause. Clean up startup apps, keep the drive free, stay updated and control heat, and most machines feel new again. If yours still struggles after all 11 fixes, an SSD or RAM upgrade is the best value for money before you think about replacing it.

FAQs

Is Windows 11 slower than Windows 10?

On supported hardware, performance is similar. Slowdowns usually come from apps, storage or heat rather than the OS itself.

How much RAM does Windows 11 need to run smoothly?

8GB is the practical minimum; 16GB is comfortable for multitasking.

Does cleaning the fan really help?

Yes. Dust blocks airflow, raises temperatures and causes throttling, which directly slows your laptop.
