The laptop slows down: what to do to get it back up to speed?

Has your laptop suddenly started to hesitate when opening programs, and simple tasks take minutes to complete? This doesn't always mean it's time to buy a new device. In 80% of cases, brakes are associated with software problems that can be solved independently - without contacting a service center or purchasing additional hardware.

We analyzed the typical reasons why laptops slow down Windows 10/11, macOS And Linux (including popular distributions like Ubuntu And Mint), and also collected proven optimization methods. In the article you will find:

• 🔍 Diagnostics “bottlenecks” - how to determine what exactly is slowing down: processor, RAM, disk or software.
• ⚡ Quick solutions - what to do right now to make the laptop work faster.
• 🛠️ Deep optimization — system settings that will speed up work by 30-50%.
• 💾 Hardware features — when you can’t do without an upgrade and how to save money on it.

We paid special attention hidden features of Windows 11 that slow down laptops on weak hardware (for example, background indexing for Windows Search or forced use DirectStorage on HDD). We also sorted out myths - for example, why registry cleaning almost never helps, but SSD defragmentation generally dangerous.

1. Diagnostics: why is the laptop slow?

Before you fix anything, you need to understand what exactly is slowing down. The laptop may freeze due to:

• 🖥️ CPU — 100% loading even when idle (viruses or drivers are often to blame).
• 🧠 RAM — there is not enough RAM, the system is actively using the page file.
• 💾 Hard drive/SSD — the disk is 100% loaded, the read/write speed drops to 1-2 MB/s.
• 🔌 Power - the laptop runs on battery power in energy saving mode (especially important for Lenovo And HP).
• 🦠 Viruses/malware — background mining scripts or spyware.

To check the hardware, open Task Manager (Ctrl+Shift+Esc on Windows or Activity Monitor on macOS). Please note:

• 📈 CPU load — if in idle time it’s 20-30%, this is the norm. If 80-100%, look for a problematic process.
• 🧩 RAM usage — if >90% occupied, the system slows down due to swapping (using the disk as RAM).
• 💿 Disk activity — constant loading at 100% HDD speaks of fragmentation or failures.

If in Task Manager there are no obvious resource hogs, check temperature. Overheating is one of the main causes of brake problems. To do this:

1. Download HWMonitor (Windows) or iStat Menus (macOS).
2. Run a stress test (for example, in Prime95 or Cinebench).
3. If the CPU/GPU temperature exceeds 85°C — Thermal paste needs to be cleaned or replaced.

⚠️ Attention: If laptop ASUS ROG, MSI or Acer Predator slows down in games, but shows normal results in benchmark tests - culprit throttling (forced reduction in frequencies due to overheating or weak power supply).

2. Quick ways to speed up your laptop (in 10 minutes)

If you don't have time for in-depth diagnostics, try these emergency measures:

Close unnecessary programs in Task Manager|Disable startup of unnecessary applications|Empty the recycle bin and temporary files|Reboot your laptop (yes, it works!)|Check your network connection (slow Wi-Fi slows down cloud services)-->

The most effective way is disable startup. On Windows:

1. Click Win + R, enter msconfig.
2. Go to the tab Autoload (or open Task Manager → Startup).
3. Disable everything except antivirus and system utilities (for example, NVIDIA GeForce Experience or Realtek Audio).

On macOS:

1. Open System Preferences → Users and Groups → Login Items.
2. Uncheck unnecessary programs (especially Adobe Creative Cloud, Microsoft OneDrive, Zoom).

Another quick way - clearing temporary files:

• 🪄 On Windows: Win + R → %temp% → delete everything (except for files that are “not deleted”).
• 🍎 On macOS: ~/Library/Caches/ (delete folders with names of unnecessary programs).

3. Windows optimization: hidden settings for speeding up

Windows 10 and 11 are tuned by default for "versatility" rather than performance. Here's what you can do disable without risk:

Settings	How to disable	Effect
Visual effects (animations, shadows)	Control Panel → System → Advanced Settings → Performance → Get better performance	Speed up the interface by 10-15%
Background indexing for search	Services → Windows Search → Startup type: Manual	Reducing disk load
DiagTrack (telemetry collection)	Services → Connected User Experiences and Telemetry → Disable	Less network activity
Superfetch (SysMain)	Services → SysMain → Disable	Less load on RAM and SSD

For Windows 11 there are additional tricks:

• 🎨 Disable transparency and animations in Settings → Personalization → Colors → Transparency Effects.
• 📱 Disable virtualization for Android programs (if you don't use Windows Subsystem for Android).
• 🔒 Disable Secure Boot in the BIOS if you don't use it BitLocker (gives +5% performance on older laptops).

⚠️ Attention: Do not disable the service Windows Update completely - this can lead to problems with drivers. Instead, set the active clock to Settings → Update & Securityso that updates are not installed during business hours.

4. Optimizing macOS: what slows down your MacBook?

Laptops Apple also slow down, especially after updates macOS Ventura or Sonoma. Main reasons:

• 🍏 Incompatible software - old versions Adobe Photoshop or Final Cut Pro may conflict with the new OS.
• 🔄 Too many migrations - transfer data from old Mac to new via Migration Assistant often copies “garbage”.
• 🛡️ FileVault — disk encryption eats up to 10% of performance on HDD and old SSD.

What to do:

1. Clear system cache:

   sudo purge

   (in Terminal - removes unused kernel cache).

2. Disable unnecessary extensions in System Settings → Extensions.
3. Reset SMC and NVRAM (especially if your MacBook wakes up slowly or won't charge):

   sudo nvram -c

   (after completing, reboot your laptop).

If it slows down Safari:

• 🚫 Disable tabs in background in Settings → Tabs → Close tabs: Every other day.
• 🗑️ Clean site history and data (especially if you have a lot of tabs open with Google Docs or YouTube).

How to speed up an old MacBook Pro (2012-2015)

Install macOS Monterey with patch OpenCore Legacy Patcher - this will provide support for new functions without loss of performance. Also replace HDD on SSD (even budget Kingston A400 will speed up loading by 5 times).

5. Linux: why is Ubuntu/Mint slow?

Linux usually runs faster than Windows, but there are pitfalls here too. Most often, brakes are associated with:

• 🐧 Wrong choice of environment — GNOME or KDE Plasma require more resources than XFCE or LXQt.
• 🐍 Snaps and flatpacks - universal packages (.snap, .flatpak) work slower than native ones.
• 🔄 Swap file - if there is little RAM, the system actively uses swapwhat slows down HDD.

How to optimize:

1. Install a lightweight environment:

   sudo apt install xubuntu-desktop

   (for XFCE based on Ubuntu).

2. Disable unnecessary services:

   sudo systemctl disable --now snapd.service

   (if you don't use snap-packages).

3. Set up swappiness (how often the system uses swap):

   sudo sysctl vm.swappiness=10

   (meaning 10 instead of standard 60 will reduce disk usage as RAM).

For Linux Mint useful to disable animations:

• 🖥️ Go to Settings → Desktop Effects.
• 🚫 Disable Window animation And Desktop switching effects.

6. Hardware solutions: when to update hardware

If software methods do not help, the problem is in the hardware. Here symptoms, which require an upgrade:

• 💾 The laptop slows down even in BIOS - problem with HDD or motherboard.
• 🧠 When opening 3-4 tabs in the browser, 100% of the RAM is occupied - more RAM is needed.
• 🎮 Games or videos slow down even at minimum settings - weak video card or overheating.

The most effective upgrades in terms of price/result ratio:

Component	Minimum Requirements (2026)	Recommendations	Effect
RAM	8 GB	16-32 GB DDR4 (enough for the office Crucial or Kingston)	Speed up multitasking by 40-60%
SSD	128 GB SATA	500 GB NVMe (Samsung 980, WD Black SN770)	System boot in 5-10 seconds
Thermal paste	Dried/withered	Arctic MX-6 or Noctua NT-H2	Temperature reduction by 10-15°C

If the laptop is older than 5 years, pay attention to:

• 🔋 Battery - A worn out battery can limit performance (especially in Lenovo ThinkPad).
• 🖥️ Matrix - if the screen is on 1366×768, replacement by Full HD will reduce the load on the GPU.
• 🔌 Power supply - weak adapter (for example, 45W instead of 65W) causes throttling.

⚠️ Attention: Before upgrading, check maximum supported amount of RAM for your model. For example, Dell Inspiron 15 3000 often limited 8 GB, even if there are physically 2 slots.

7. Viruses and malware: how to check and remove

If the laptop suddenly starts to slow down, the reason may be viruses or miners (scripts that mine cryptocurrency on your processor). Signs of infection:

• 🕵️‍♂️ Unknown processes in Task Manager (For example, svchost.exe with high load).
• 🔗 Constant network activity even without running programs.
• 📁 The appearance of strange files (for example, ~$*.tmp or autorun.inf).

How to check:

1. Download Malwarebytes or Kaspersky Virus Removal Tool (free versions).
2. Run full check (not fast!).
3. Check Hosts-file (C:\Windows\System32\drivers\etc\hosts) for suspicious entries.

For Linux And macOS:

• 🐧 On Linux use rkhunter:

  sudo apt install rkhunter
  sudo rkhunter --check

• 🍎 On macOS, check /Library/LaunchDaemons/ And /Library/LaunchAgents/ for the presence of unknown files.

If you find a miner, delete it via Autoload And Task Scheduler (Task Scheduler). They are often disguised as:

• 📁 Windows Update Service (but not the real one!).
• 🖼️ NVIDIA/AMD Driver Helper (unless you have a discrete graphics card).
• 🔄 Java Update Scheduler (if Java is not installed).

FAQ: Frequently asked questions about laptop brakes

❓ The laptop slows down after updating Windows. What to do?

Rollback update via Settings → Update and security → Update history → Uninstall updates. If that doesn't help, try:

1. Reset update cache:

   net stop wuauserv
   net stop cryptSvc
   net stop bits
   net stop msiserver
   ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
   ren C:\Windows\System32\catroot2 catroot2.old
   net start wuauserv
   net start cryptSvc
   net start bits
   net start msiserver

2. Disable driver updates via Windows Update (via gpedit.msc for Pro version).

❓ The laptop slows down when connected to Wi-Fi. What's the matter?

Possible reasons:

• 📶 The Wi-Fi adapter driver is out of date or conflicts with the system. Update it manually from the manufacturer's website (not through Windows Update!).
• 🔒 Enabled on the router WPA3, which is not supported by older laptops. Switch to WPA2.
• 📡 Neighboring networks interfere. Change the Wi-Fi channel in the router settings (use Wi-Fi Analyzer for analysis).

❓ The laptop slows down in games, but benchmarks show normal FPS. Why?

This microfreezes — short-term freezes due to:

• 🔥 Throttling — the processor or video card reduces frequencies due to overheating. Check the temperatures in HWMonitor.
• 💾 Shader cache - if the game is the first of its kind (for example, Cyberpunk 2077), it compiles shaders during the game. Solution: Play for 10-15 minutes on minimum settings, then restart the game.
• 🔌 Nutrition shortages - if you play on battery power or a weak power supply, FPS will drop. Connect your laptop to the network.

Also check your settings NVIDIA Control Panel or AMD Adrenalin:

• Disable V-Sync (if your monitor does not support G-Sync/FreeSync).
• Install Preferred refresh rate to the maximum value.

❓ The laptop slows down after replacing the HDD with an SSD. What's wrong?

Possible problems:

1. AHCI mode is not enabled in BIOS. Switch from IDE on AHCI (Windows may need to be reinstalled).
2. SSD connected via USB adapter (for example, in the DVD drive slot). Speed will be limited USB 2.0/3.0.
3. Chipset drivers not updated. Download them from the laptop manufacturer's website (not from Intel/AMD!).
4. Defragmentation enabled for SSD. Disable it:

   fsutil behavior set disabledeletenotify 0

   (check that TRIM enabled).

❓ The laptop slows down when working with files on the external drive. How to speed it up?

The problem may be:

• 🔌 Connection interface — USB 2.0 limited by speed 480 Mbit/s (≈60 MB/s). Connect the drive to USB 3.0 (blue port) or USB-C.
• 💾 File system - if the disk is formatted in FAT32, reformat to exFAT or NTFS.
• 🛡️ Antivirus - some (for example, Kaspersky) scan external drives in real time. Add the disk to exceptions.

For maximum speed:

• Use USB 3.1 Gen 2 or Thunderbolt (up to 40 Gbps).
• If you work with small files (photos, documents), combine them into archives (.zip, .rar).
