The laptop is incredibly slow: what to do in 2026

Has your laptop taken longer to boot, and simple tasks like opening a browser have become a test of patience? Brakes are not a death sentence, but a signal that the system needs help. In 90% of cases, the problem can be solved on your own, without spending money on specialists or a new device. The main thing is to do it right diagnose the cause and apply targeted optimization techniques.

We have collected current for 2026 ways to speed up laptops Windows 10/11 And macOS, which work even for weak configurations with 4 GB RAM And HDD. There are no universal “magic buttons” here - only specific actions with explanations of why they help. And if you are afraid of breaking something, at the end of the article there is safe checklist for beginners.

1. Diagnostics: why is the laptop slow?

Before treatment, a diagnosis must be made. Brakes may be caused by hardware problems (hardware), software (software) or a combination thereof. Here's how to quickly identify the culprit:

• 🔍 Task Manager (Windows): Click Ctrl+Shift+Esc → "Performance" tab. If CPU or RAM loaded at 90%+ when idle - the problem is in the background.
• 📊 macOS monitoring: Open "Activity" via Spotlight (Cmd+Space). Pay attention to processes kernel_task - their high load indicates overheating.
• 💾 Disk check: enter at the command line wmic diskdrive get status (Windows) or diskutil verifyVolume / (macOS). Status Pred Fail means that HDD/SSD is dying.

Typical symptoms and their causes:

⚠️ Attention: If laptop Acer, Lenovo or HP older than 5 years it slows down even after cleaning - culprit built-in battery. A battery that has lost capacity limits performance. Check in cmd team powercfg /batteryreport.

2. Hardware causes of brakes (and how to fix them)

If diagnostics show problems with the hardware, here's what to do:

• 🧹 Cleaning from dust: Disassemble the laptop (or take it to a service center) and blow it out radiator And cooler compressed air. Especially relevant for Asus ROG, MSI and game models.
• 🧪 Replacing thermal paste: If the processor temperature exceeds 90°C in idle time (checked in HWMonitor or Core Temp), it's time to change the thermal paste. For modern Intel Core i7/i9 And AMD Ryzen use pastes with thermal conductivity 10+ W/mK.
• 💾 Replacing HDD with SSD: Even budget Samsung 870 EVO or Crucial MX500 speeds up system boot time 5-7 times. For laptops with mSATA or M.2 Compact models are suitable.
• 🔋 Battery problems: Disconnect the battery (if removable) and work from the mains. If the brakes fail, the battery needs to be replaced.

Critical case: If laptop Dell Latitude or ThinkPad suddenly started to slow down after updating the BIOS - roll back the firmware via Advanced Boot Options (F12). Some BIOS versions 2023 contains bugs that reduce performance by 30%.

3. Software optimization of Windows 10/11

Even on a powerful laptop Windows may slow down due to clutter. Follow this algorithm:

1. Cleaning startup:

   Click Ctrl+Shift+Esc → "Startup" tab. Disable all programs except antivirus and drivers. Especially "gluttonous" NVIDIA GeForce Experience, iTunes Helper And Adobe Creative Cloud.

2. Disabling visual effects:

   Go to Settings → System → About → Additional system settings → Performance. Select "Get better performance."

3. Disk Cleanup:

   Run cleanmgr through Win+R, then run at command prompt (administrator):

   Dism /Online /Cleanup-Image /AnalyzeComponentStore
   Dism /Online /Cleanup-Image /StartComponentCleanup /ResetBase

For Windows 11: Disable unnecessary features via Settings → Applications → Additional components. Remove Xbox Game Bar, 3D Viewer And News and Interests — they load the system with background processes.

⚠️ Attention: Don't use "optimizers" like CCleaner or Advanced SystemCare. They often delete critical files and worsen the brakes. Use the built-in Windows tools instead.

4. macOS optimization (for MacBook)

Is your MacBook slow? Here's what to do on Ventura And Sonoma:

• 🍎 Reset SMC and NVRAM:

  Turn off your MacBook, hold down Shift+Control+Option + power button for 10 seconds. Then turn it on and immediately press Command+Option+P+R for 20 seconds.

• 🗑️ Clearing cache:

  Open Terminal and enter:

  sudo rm -rf /Library/Caches/*
  sudo rm -rf ~/Library/Caches/*

• 🚫 Disabling Spotlight:

  If indexing files loads the system, add the disk to the exceptions: System Preferences → Siri and Spotlight → Privacy.

For older MacBooks (2015 and earlier) with HDD the only radical solution is replacement with SSD + clean installation of macOS. Even MacBook Air 2013 after the upgrade it works faster than new models with eMMC.

5. Viruses and malware: how to check and remove

Brakes can cause:

• 🕵️ Miners (use CPU/GPU to mine cryptocurrency).
• 📤 Adware (adware that loads the network).
• 🔑 Keyloggers (programs for data theft).

How to check:

1. Download Malwarebytes (free version) and perform a full scan.
2. Check the processes in Task Manager to unfamiliar names (for example, svchost.exe with high load).
3. Use Process Explorer from Microsoft for in-depth analysis.

If the antivirus doesn’t find anything, but the laptop slows down when connected to the Internet, check hosts file (C:\Windows\System32\drivers\etc\hosts). Remove all lines except 127.0.0.1 localhost.

6. Radical methods: when all else fails

If all of the above doesn't work, it's time for serious action:

• 🔄 Reset Windows/macOS to factory settings:

  On Windows: Settings → Update & Security → Recovery → Reset PC.

  On Mac: Command+R at boot → "Reinstall macOS".

• 🛠️ Replacing thermal pads:

  Relevant for laptops MSI, Gigabyte And Alienware, where thermal paste is applied to VRM modules And chipset.

• 🔌 Disabling Turbo Boost:

  For Intel Core i7/i9 with overheating: disable Turbo Boost in BIOS or via ThrottleStop. This will reduce performance by 10%, but will eliminate lag.

Last chance: If the laptop slows down even after resetting, check RAM on errors through Windows Memory Diagnostic (mdsched.exe). Broken RAM sticks can cause freezes without BSOD.
