Why Your Windows 10 Laptop Is Slow
Looking for how to speed up Windows 10 laptop performance? A laptop that felt fast out of the box slows down over time for predictable reasons. Programs pile up and run in the background. The hard drive fills with temporary files, old downloads, and cached data. Windows updates install automatically and sometimes introduce performance problems. Malware might be running quietly without obvious symptoms.
The good news is that most of these issues are fixable without spending money. The fixes below are ordered from quickest and easiest to more involved. Start at the top and work your way down. You’ll likely notice improvement within the first few steps.
Disable Startup Programs
Every program that launches at startup competes for CPU and memory before you even open anything. Most people have a dozen or more programs loading automatically that they don’t need running all the time: Spotify, Discord, OneDrive, Adobe updaters, printer utilities, and manufacturer bloatware.
- Press Ctrl + Shift + Esc to open Task Manager.
- Click the “Startup” tab. If you don’t see tabs, click “More details” first.
- Look at the “Startup impact” column. Right-click anything marked High or Medium that you don’t need immediately at boot and select “Disable.”
- Keep your antivirus and other core services enabled. Disable things like Spotify, Teams, Skype, game launchers, and manufacturer utilities.
This alone can cut your boot time in half on a cluttered system. The programs aren’t uninstalled. They just won’t launch automatically. You can still open them manually whenever you need them.
Run Disk Cleanup
Windows accumulates gigabytes of temporary files, system cache, old update files, and error reports over time. Disk Cleanup removes this safely.
- Type “Disk Cleanup” in the Start menu search and open it.
- Select your C: drive and click OK.
- Check all boxes, especially “Temporary files,” “Thumbnails,” and “Delivery Optimization Files.”
- Click “Clean up system files” for more options, including “Previous Windows installation(s)” which can free up 10+ GB after major updates.
- Click OK and confirm.
On a laptop that hasn’t been cleaned in a year or more, this often frees 5 to 20 GB. The freed space directly helps performance if your drive was nearly full, since Windows needs free space for virtual memory and temporary operations.
Uninstall Programs You Don’t Use
Unused programs take up storage space and sometimes run background processes that eat memory and CPU cycles. Manufacturer-installed bloatware (trial antivirus, games, utility apps you never asked for) is especially worth removing.
- Open Settings (Windows key + I) and go to Apps then Apps & features.
- Sort by “Install date” to see what was added recently, or by “Size” to find the biggest space consumers.
- Click any program you don’t use and select “Uninstall.”
Don’t uninstall anything you don’t recognize without checking what it is first. Some entries are drivers or system components that Windows needs. If you’re unsure, search the program name online before removing it.
Check for Malware
Malware running in the background consumes CPU, memory, and network bandwidth. A sudden slowdown without an obvious cause is a classic sign of infection. Even if you have antivirus software installed, it’s worth running a manual scan.
- Open Windows Security (type it in the Start menu).
- Click “Virus & threat protection” then “Scan options.”
- Select “Full scan” and click “Scan now.” This takes 30 minutes to over an hour.
- For a second opinion, download Malwarebytes Free from malwarebytes.com and run a scan. It catches things Windows Defender sometimes misses.
Adjust Visual Effects
Windows 10 uses animations, transparency, shadows, and smooth scrolling that look nice but consume GPU and CPU resources. On older hardware or laptops with integrated graphics, turning these off makes the interface feel noticeably snappier.

- Type “performance” in the Start menu and select “Adjust the appearance and performance of Windows.”
- Select “Adjust for best performance” to disable everything, or select “Custom” and uncheck specific effects.
- The effects that consume the most resources are “Animate windows when minimizing and maximizing,” “Fade or slide menus into view,” and “Show shadows under windows.”
- Click Apply.
The interface looks more basic with these disabled, but the performance gain on older machines is real and immediate. You can always turn them back on later if you miss the visual polish.
Manage Background Apps
Windows 10 allows apps to run in the background even when you’re not using them. This includes apps from the Microsoft Store that update, fetch notifications, and consume resources silently.
- Open Settings then Privacy then Background apps.
- Toggle off “Let apps run in the background” to disable all of them, or individually disable apps you don’t need running (like Maps, Groove Music, Mail if you use a browser for email, etc.).
Keep apps enabled that you actually want notifications from (like messaging apps). Disable everything else. The performance hit from individual background apps is small, but collectively they add up, especially on laptops with 4 or 8 GB of RAM.
Change Your Power Plan
Many laptops default to a “Balanced” power plan that throttles CPU performance to save battery. Switching to “High performance” removes this throttle and lets the processor run at full speed.
- Open Control Panel and go to Hardware and Sound then Power Options.
- Select “High performance.” If you don’t see it, click “Show additional plans.”
- If “High performance” isn’t listed at all, open Command Prompt as administrator and type: powercfg /setactive 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c
The tradeoff is shorter battery life. Use “High performance” when plugged in and switch back to “Balanced” when on battery. Some gaming laptops have manufacturer-specific performance modes (like Lenovo Vantage or ASUS Armoury Crate) that go even further.
Free Up Drive Space
A nearly full hard drive or SSD causes significant slowdowns. Windows needs free space for virtual memory (page file), temporary files, and system operations. Keep at least 15 to 20% of your drive free for smooth performance.
Beyond Disk Cleanup, check your Downloads folder for large files you’ve already used, clear your Recycle Bin, and move photos and videos to an external drive or cloud storage. Use Settings then System then Storage to see a breakdown of what’s consuming space on your drive.
The Storage Sense feature in the same settings menu can automate cleanup. Enable it and configure it to delete temporary files and empty the Recycle Bin automatically every 30 days.
Add More RAM
If your laptop has 4 GB of RAM, upgrading to 8 GB or 16 GB is the single most impactful hardware upgrade you can make. Windows 10 itself uses about 2.5 to 3 GB, leaving very little headroom on a 4 GB machine. With a browser, email, and one or two other apps open, the system starts swapping to disk (using your storage drive as temporary memory), which is dramatically slower than real RAM.
Check whether your laptop supports RAM upgrades before buying anything. Some laptops (especially ultrabooks and many models made after 2019) have soldered RAM that can’t be replaced. Use a free compatibility tool like the System Scanner at crucial.com to check what works and find the right memory module for your machine.

Replace Your Hard Drive with an SSD
If your laptop still runs on a mechanical hard drive (HDD), swapping it for a solid-state drive (SSD) is transformative. Boot times drop from 60+ seconds to under 15 seconds. Programs open instantly instead of after several bounces. File copies finish in a fraction of the time. This is the single biggest performance upgrade you can make to an older laptop.
A 500 GB SATA SSD costs $40 to $60. The installation involves cloning your existing drive to the new SSD (using free software like Macrium Reflect or Clonezilla) and physically swapping the drives. Most laptops with mechanical hard drives use a standard 2.5-inch bay that accepts any SATA SSD.
Update Windows and Drivers
Running outdated Windows versions or drivers can cause performance issues, especially with graphics and chipset drivers. Microsoft regularly releases patches that fix performance problems introduced by earlier updates.
- Open Settings then Update & Security then Windows Update.
- Click “Check for updates” and install anything available.
- After updating Windows, check for driver updates through Device Manager or your laptop manufacturer’s support website.
Graphics drivers in particular affect performance significantly. If you have an NVIDIA or AMD GPU, download the latest driver directly from the manufacturer’s website rather than relying on Windows Update, which often delivers older versions.
Note: As of August 2026, Windows 10 has reached end of support (October 2025 was the cutoff). Microsoft is no longer releasing security updates for Windows 10. While the tips in this guide still work to improve performance, you should seriously consider upgrading to Windows 11 if your hardware supports it, or planning for a hardware upgrade if it doesn’t.
Disable Search Indexing
Windows continuously indexes files on your drive to speed up search results. On mechanical hard drives, this indexing process causes noticeable disk thrashing and slowdowns. On SSDs the impact is smaller, but disabling it still frees up some CPU and disk resources.
- Type “services” in the Start menu and open the Services app.
- Scroll down to “Windows Search” and double-click it.
- Set the Startup type to “Disabled” and click “Stop.”
- Click OK.
After disabling this, the Windows search bar still works but returns results more slowly since it searches in real time instead of using a pre-built index. If you rarely use the search bar, you won’t notice any difference.
Will a factory reset make my laptop faster?
Yes, a factory reset returns your laptop to its original state, removing all installed programs, accumulated junk files, and potential malware. It’s the nuclear option when nothing else works. Back up your important files first (to an external drive or cloud storage), then go to Settings, Update & Security, Recovery, and click “Reset this PC.” Choose “Remove everything” for the cleanest result. The laptop will feel like new afterward, but you’ll need to reinstall all your programs.
How much RAM does Windows 10 need?
Microsoft’s minimum requirement is 2 GB, but that’s barely functional. 4 GB is usable for very light tasks (one or two browser tabs and basic apps). 8 GB is the sweet spot for normal use, covering browsing, Office, streaming, and moderate multitasking. 16 GB is worth it if you regularly have many browser tabs open, use Photoshop or video editing software, or run virtual machines.
Should I upgrade to Windows 11 for better performance?
Windows 11 performs about the same as Windows 10 on identical hardware. In some benchmarks it’s slightly faster; in others, slightly slower. The performance difference alone isn’t a strong reason to upgrade.
That said, Windows 10 reached end of support in October 2025. As of August 2026, it no longer receives security updates from Microsoft. This means your laptop is exposed to newly discovered vulnerabilities without official patches. If your laptop meets the Windows 11 requirements (TPM 2.0, 8th gen Intel or newer, etc.), upgrading is now strongly recommended for security reasons. If your hardware doesn’t qualify for Windows 11, consider investing in a newer machine or at minimum running a strong third-party security suite to help cover the gaps left by the missing updates.
