How do you deep clean a laptop hard drive?

Why deep clean a laptop hard drive?

There are several reasons why you may want to do a deep clean of your laptop’s hard drive:

  • Improve performance – Over time, clutter and files that you no longer need can slow down your laptop’s performance. Doing a deep clean helps free up storage space and speeds things up.
  • Remove viruses and malware – A deep clean scan can help detect and remove any viruses, malware or other harmful files that may have infected your hard drive.
  • Protect privacy – Before donating, recycling or selling your laptop, you’ll want to make sure all personal files, browsing history, saved passwords and other sensitive information are completely wiped from the hard drive.
  • Start fresh – If your laptop is running slowly or acting buggy, a deep clean can help give it a fresh start and make it feel like new again.

Doing a periodic deep clean is recommended to keep your laptop in tip-top shape. Follow the steps below to thoroughly clean and optimize your hard drive.

Back up your files

Before doing any kind of deep clean, it’s critical to back up your important files and data. This ensures you have a copy of anything you need before wiping your hard drive.

To back up your laptop:

  • Copy important files to an external hard drive or cloud storage. This includes documents, photos, music, videos, program installation files and any other data.
  • Use backup software to do a full system backup. This will save a snapshot of your full hard drive contents and settings.
  • Manually back up settings for programs and applications. Note any license keys or login information you may need later.

Taking these steps ensures you have everything you need before scrubbing your hard drive clean.

Use disk cleanup utilities

Disk cleanup utilities help remove unnecessary files from your hard drive to free up space. Use the following tools:

  • Windows Disk Cleanup – This built-in tool finds and deletes temporary files, empty Recycle Bin, clear system caches and more. Click the Start menu and search “disk cleanup”.
  • CCleaner – A popular optimization tool that deletes junk files, clears caches, empties Recycle Bin and more. Use the WindowsCleaner and RegistryCleaner features.
  • Storage Sense – A Microsoft tool that automatically frees up space by deleting unimportant files and optimizing drives.
  • TreeSize Free – Scans drives and shows how disk space is being used, making it easy to find and delete large files and folders.

Run these utilities one-by-one to free up as much space as possible on your laptop’s hard drive.

Delete unused programs

Over time, unused programs accumulate and take up precious hard drive space. Here’s how to remove them:

  • Open Settings > Apps to view installed applications.
  • Go through the list and look for any apps you haven’t used in awhile or no longer need.
  • Select the app and choose Uninstall. This will remove the program from your hard drive.
  • Alternatively, you can right-click a program and choose Uninstall from the menu.

Removing unused applications frees up space and declutters your laptop.

Wipe browser history and caches

Browsing history, cookies, caches and other browser data can build up over time. Here’s how to wipe it:

  • Google Chrome – Open Chrome, click the 3-dot menu > History > Clear browsing data. Select cookies, cached images, etc. and choose a time range.
  • Mozilla Firefox – Click the 3-line menu > Options > Privacy & Security > Clear Data. Select cookies, cache, history, etc. and choose time range to clear.
  • Microsoft Edge – Click the 3-dot menu > Settings > Privacy, search, and services > Choose what to clear. Select data types and time period, then click Clear.

This removes unneeded browser data while keeping your bookmarks and other important information.

Check for and remove viruses

Viruses, malware, spyware and other threats can secretly install themselves on your computer. Use antivirus software to scan for these issues:

  • Use Windows Security to do a quick or full antivirus scan. It’s built into Windows 10.
  • Install a third-party antivirus like Malwarebytes or Avast Free Antivirus. Run a full system scan to detect threats.
  • Use AdwCleaner to check for potentially unwanted programs and browser add-ons.
  • Run scans regularly to detect the latest threats. Remove anything harmful that is found.

This protects your laptop and personal data from malicious software.

Update drivers and firmware

Device drivers and firmware that are out-of-date can cause performance issues on a laptop. Updating them improves stability and optimizes how your computer runs.

  • Open Windows Update to install the latest driver and firmware updates from Microsoft.
  • Visit your laptop manufacturer’s support site for any additional updates specific to your model.
  • Manually update drivers for external devices by visiting the manufacturer websites.

Keeping everything up-to-date avoid bugs and boosts speed.

Tune up the hard drive

Over time, hard drives can become fragmented and disorganized. Use drive tuning utilities to optimize and defrag your laptop’s hard drive:

  • Run Windows Disk Defragmenter to rearrange files and consolidate free space.
  • Use Auslogics Disk Defrag for enhanced defrag and optimization features.
  • Run chkdsk /f to scan drive and fix detected errors.
  • Use Samsung Magician (for Samsung SSDs) or other manufacturer tools to optimize solid state drives.

Defragging and tuning your hard drive improves file access speeds and overall performance.

Clean the physical components

Dust, debris and dirt buildup inside your laptop can lead to overheating and hardware malfunctions. Here are some tips for cleaning the physical components:

  • Use compressed air to blow out vents, fans and heat sinks. This removes built-up dust.
  • Open up the bottom cover and clean dust from inside the case with compressed air.
  • Wipe down the case exterior using a microfiber cloth and plastic cleaner.
  • Use a cotton swab dipped in rubbing alcohol to gently clean battery connectors and port contacts.
  • Check fans and replace thermal paste if needed to prevent overheating issues.

Physically cleaning the laptop’s components helps it run cooler and extend its lifespan.

Reset the operating system

If your laptop is still having issues after trying the steps above, you may want to reset your Windows operating system. Here are a couple options:

  • Factory reset – This completely erases and reinstalls Windows, resetting it to factory condition.
  • PC refresh – This reinstalls Windows but keeps your personal files and Windows settings.
  • Clean install – Making a bootable USB drive and doing a fresh Windows install formats the hard drive.

Resetting Windows provides the most thorough clean slate for your laptop’s hard drive.


Doing a periodic deep clean of your laptop hard drive helps keep it running at peak performance. Follow the steps in this guide to:
