Your laptop feels sluggish at the worst possible time: right before a call, while exporting a file, or when you just want to open a browser tab without waiting. The good news is you don’t need to be a technician—or spend money—to see real improvements fast. With a few targeted changes, you can boost laptop speed in about 15 minutes by cutting background clutter, freeing up storage, and dialing in the settings that quietly drain performance. The goal isn’t perfection; it’s quick wins that make your computer feel snappy again today. Follow the steps below in order, and you’ll remove the most common bottlenecks that slow everyday tasks like booting, launching apps, and multitasking.
Minute 0–3: Stop the biggest performance drains (startup and background apps)
Most “slow laptop” complaints come from too many programs running without permission. Startup apps, background updaters, and always-on sync tools can consume CPU, memory, and disk activity before you even open what you actually need.
Disable unnecessary startup programs (Windows and macOS)
Aim to leave only essentials enabled, such as security software and core drivers. Everything else should justify why it deserves to start automatically.
Windows 10/11:
1. Press Ctrl + Shift + Esc to open Task Manager.
2. Click Startup apps (or Startup tab).
3. Disable items you don’t need immediately after boot, such as:
– Chat clients you rarely use
– Game launchers
– Non-essential update agents
– Vendor utilities you never open
macOS:
1. Go to System Settings (or System Preferences) > General > Login Items.
2. Remove apps you don’t need launching at login.
3. Toggle off “Allow in the Background” for tools you don’t rely on.
Quick rule: If you can’t explain what it is, search it first. Disabling is safer than uninstalling.
Close high-impact background processes
Even after startup cleanup, background processes can keep your laptop speed low.
Windows:
– In Task Manager > Processes, sort by CPU or Memory and close obvious non-essential apps.
– If “Disk” is at 100% often, note which process is causing it (common culprits include heavy syncing or antivirus scans).
macOS:
– Open Activity Monitor > CPU/Memory.
– Quit apps that are clearly hogging resources and not needed.
Tip: Don’t force-quit system processes you don’t recognize. Target user apps first (browsers with many tabs, collaboration tools, cloud drives, etc.).
Minute 3–7: Free up storage space (a fast way to boost laptop speed)
When your drive is nearly full, your system has less room for temporary files and virtual memory, which can make everything feel delayed. As a general guideline:
– Windows: try to keep at least 15–20% of your drive free
– macOS: keep at least 10–15% free for smooth operation
Use built-in cleanup tools (safe and quick)
Windows:
1. Open Settings > System > Storage.
2. Run Storage Sense or Temporary files cleanup.
3. Remove items like:
– Temporary files
– Delivery Optimization files
– Recycle Bin contents (review first)
– Old Windows update cleanup (often large)
macOS:
1. Go to System Settings > General > Storage.
2. Review Recommendations such as:
– Empty Trash automatically
– Reduce clutter
– Review large files
Example: If you reclaim 10–30 GB in a few minutes, you often see immediate improvements in app launching and file operations.
Find and delete the real space hogs
If you’re short on time, target the biggest files first:
– Downloads folder (old installers, duplicate ZIPs)
– Large videos you’ve already uploaded
– Old device backups
– Unused apps you haven’t opened in months
Helpful tools:
– Windows: Settings > Storage > Show more categories
– macOS: Storage > Documents or Applications (sort by size)

Minute 7–10: Browser cleanup for instant “feels faster” results
For many people, “my laptop is slow” actually means “my browser is overloaded.” Too many tabs, heavy extensions, and persistent background web apps can eat memory and CPU.
Reduce tabs and suspend the heavy ones
Try this quick reset:
– Bookmark important tabs into a folder and close them
– Keep only what you’re actively using (10–15 tabs is already heavy on low-RAM systems)
– Restart the browser completely (close all windows, then reopen)
If you rely on many tabs, consider built-in tools:
– Chrome/Edge: Performance or Memory Saver features
– Safari: Manage extensions and remove those you don’t use
Remove extensions you don’t trust or need
Extensions can impact laptop speed in subtle ways, especially those that:
– Modify search results
– Inject coupons into shopping pages
– Run “productivity” trackers constantly
– Block ads but consume heavy resources
Quick checklist:
– Disable first, test performance, then remove
– Keep extensions updated
– Stick to reputable publishers and minimal permissions
If you notice random pop-ups, homepage changes, or unusually high CPU usage from the browser, it’s time to audit extensions immediately.
Minute 10–13: Tune power and performance settings (without harming battery)
Power settings can cap performance, especially on laptops that default to battery-saving modes. You can often raise laptop speed with one or two toggles—then switch back when you’re done.
Set an appropriate power mode
Windows:
1. Go to Settings > System > Power & battery.
2. Set Power mode to:
– Best performance (when plugged in and you need speed now)
– Balanced (good everyday option)
macOS:
– On newer macOS versions, check Battery settings and disable Low Power Mode when you need maximum responsiveness.
– On Intel Macs, ensure you’re not stuck in energy-saving settings that dim performance.
Practical approach:
– Use Balanced most of the time
– Switch to Best performance when exporting, compiling, gaming, or multitasking heavily
Turn off visual effects (a quick win for older laptops)
If your device is a few years old, UI animations can contribute to lag.
Windows:
1. Search “Adjust the appearance and performance of Windows.”
2. Choose Adjust for best performance (or customize).
3. Consider leaving on:
– Smooth edges of screen fonts (for readability)
– Show thumbnails instead of icons (optional)
macOS:
1. Go to Accessibility > Display.
2. Enable Reduce motion and Reduce transparency.
These settings won’t magically double performance, but they often make the system feel more responsive—especially when RAM is limited.
Minute 13–15: Run quick health checks (updates, malware scan, and reboot)
A final 2-minute pass can prevent recurring slowdowns. Think of this as a rapid “stability sweep” after you’ve cleaned house.
Update what matters (without falling into a time trap)
Updates can improve performance, but they can also take longer than 15 minutes. The trick is to start them and schedule restarts later.
Windows:
– Settings > Windows Update > Check for updates
– Install critical security and driver updates when convenient
macOS:
– System Settings > General > Software Update
Also update:
– Your browser (often fixes memory leaks and performance bugs)
– Your video conferencing tool (Teams/Zoom/Meet apps can be resource-heavy)
Run a quick malware check and reboot properly
Malware and unwanted programs can quietly destroy laptop speed by running background tasks or hijacking browser behavior.
Windows:
1. Open Windows Security > Virus & threat protection.
2. Run a Quick scan.
macOS:
– While macOS has strong built-in protections, consider scanning with a reputable security tool if you’ve installed unknown apps or see suspicious behavior.
– Review Applications for anything unfamiliar and uninstall carefully.
Then reboot:
– A proper restart clears temporary issues, releases stuck memory, and finishes system tasks.
– If you usually close the lid and never restart, make weekly restarts a habit.
A quick note for Windows users: If you “Shut down” daily but never restart, Fast Startup can sometimes keep issues around longer. Restarting is often the cleanest reset.
Keep your laptop speed high: simple habits that prevent future slowdowns
You’ve now applied quick fixes. To maintain laptop speed, adopt a few light habits that prevent performance creep.
A weekly 5-minute maintenance routine
Once a week:
– Restart your laptop
– Clear downloads and delete large unneeded files
– Check startup apps and remove anything new you didn’t approve
– Update your browser and one or two key apps
If you want a measurable way to track improvement, time how long it takes to:
– Boot to desktop
– Launch your browser
– Open a common app (Word, Photoshop, VS Code, etc.)
Keep a simple note in your phone. If the times start creeping up, you’ll catch the slowdown early.
When quick fixes aren’t enough: two upgrades worth considering
If your laptop still struggles after these steps, the bottleneck may be hardware. Two upgrades commonly deliver the biggest results:
– Switch to an SSD (if you’re on an old hard drive): often the single biggest jump in responsiveness
– Add RAM: helpful if you multitask, keep many tabs open, or run heavier apps
If you’re unsure, check your system specs:
– Windows: Settings > System > About
– macOS: Apple menu > About This Mac
As a practical guideline:
– 8 GB RAM is workable for light use
– 16 GB RAM is a comfortable baseline for multitasking in 2026
– SSD storage is strongly recommended for nearly everyone
Your laptop should feel noticeably faster after 15 minutes of targeted cleanup: fewer startup apps, more free space, a lighter browser, and performance settings that match what you’re doing. The fastest path to better laptop speed is removing what you don’t need, then restarting so the system can reset cleanly. Pick one maintenance habit (like a weekly restart and downloads cleanup) to keep things smooth long-term.
