How to Speed Up Windows 10 Computer

Need to Speed Up Windows 10? The performance of your Windows 10 computer is vital for efficiency and productivity. Sluggish systems can be a source of significant frustration and loss of valuable time. By taking proactive steps, you can substantially improve your computer’s performance.

Below is a comprehensive beginner guide to speeding up your Windows 10 system, including:

  • Disk defragmentation.
  • Using the built-in utility cleanmgr.
  • Safely clean the system registry
  • How to Perform a Clean Installation.

Use Disk Defragmentation to Speed Up Windows 10

Disk defragmentation is a crucial maintenance task that reorganizes fragmented files on your hard drive, enhancing its efficiency. When you install applications or use files on the computer, the data is written ‘as-is’ to the disk. Over time, the files can fragment, basically scattering themselves over the disk. The more scattered the files, the longer it takes to read and write data.

Will Disk Defragmentation Work For Me?

Disk Defragmentation is common on traditional magnetic disks (the traditional HDD), and occasionally you get it on SSDs. Defragmentation is unlikely to have any impact on NVMe disks.

If you are unsure what disk you have on your computer. Do the following:

  • Press the start button and type devmgmt.msc
  • Press enter; this will open the device management.
  • Find the section that says Hard Disks and expand the tab to see what type of disk you have.
  • If you right-click on a disk, and select properties, it will give you detailed information about your disk.

How to use Windows Disk Defragmentation

As a result, when files are fragmented, your hard drive must exert more effort to locate and access them, ultimately leading to a slowdown in your system.

  1. Access the Disk Defrag tool: Go to the Start menu and search for “Defragment.” Click on “Defragment and Optimize Drives” from the search results.
  2. Selecting Drive: Choose the drive you want to defragment, typically the C: drive.
  3. Analyze and Optimize: Click the “Analyze” button first to see if your drive needs defragmentation. Next, click ‘Optimize’ to initiate the process.

Note: If your computer has a Solid State Drive (SSD), skip disk defragmentation, as it is not beneficial for SSDs.

Using Defraggler for Advanced Disk Defragmentation

While Windows does provide a built-in disk defragmentation tool, you might consider exploring third-party options for added features and greater control, ensuring a more comprehensive optimization.

Defraggler, developed by Piriform, the same company behind CCleaner, is a robust third-party option that provides advanced functionalities.

  1. Installation: Visit Piriform’s official website to download and install Defraggler.
  2. User Interface: Upon launching the application, you’ll see a list of all drives. Select the one you wish to optimize.
  3. Analyze: Click the “Analyze” button to get an overview of the drive’s fragmentation status.
  4. Defragment Options: Defraggler offers multiple ways to defragment your drive, including quick defragment, defrag-free space, and the standard full defragment.
  5. Start Defragmentation: Once you’ve chosen your defrag type, click the “Run” button to start the process.

Note: Defraggler also allows you to schedule defragmentation, targeting specific files and folders for a more personalized optimization.


Integrating Defraggler into your disk maintenance routine offers a range of enhanced features. From scheduled defragmentation to file-specific optimization, these capabilities significantly contribute to further enhancing your computer’s overall performance

Using cleanmgr to Clean Temporary Files and Speed Up Windows 10

cleanmgr or Disk Cleanup is an in-built utility that helps you remove temporary files, system files, and other unnecessary data that accumulate over time.

  1. Initiating Disk Cleanup: Press Win + R, type cleanmgr, and press Enter.
  2. Choosing Files: A list will appear, showing you the types of files that can be removed. Select those you wish to delete.
  3. Final Step: Click “OK,” then “Delete Files” to complete the cleanup.

Cleaning the Registry

Over time, your system registry accumulates outdated and unnecessary entries, which can cause system slowdowns. It’s advisable to use specialized software for this task.

  1. Backup: After clicking ‘OK,’ proceed to ‘Delete Files’ to finalize the cleanup.
  2. Download Registry Cleaner: Use a trusted, high-rated registry cleaner like CCleaner or Wise Registry Cleaner.
  3. Scan and Clean: Follow the cleaner’s instructions to scan for issues and fix them.

Warning: Incorrectly editing the registry can cause severe system problems. Use this option cautiously, and always make sure to back up your registry first.

Clean Installation of Windows 10

If your system remains sluggish despite attempting the methods mentioned above, a clean installation might be the most effective solution. This process wipes out all your data and installs a fresh copy of Windows 10.

  1. Backup Data: Store all necessary files in an external storage device.
  2. Download Installation Media: Visit the official Microsoft website and download the Windows 10 installation media.
  3. Installation: Boot your computer using the installation media and follow the on-screen prompts.

Caution: A clean installation is a drastic step and will erase all data on your system. Only proceed if you have backed up all crucial data.

Additional Tips

  • Disable Startup Programs: At system startup, certain applications initiate automatically. Disabling unnecessary startup programs can speed up your boot time.
  • Update Software: Regularly update Windows and other software to benefit from security patches and performance improvements.
  • Upgrade Hardware: Consider adding more RAM or switching to an SSD for faster data access times.

Incorporating these tips and procedures into your routine will lead to a substantial improvement in your computer’s performance and efficiency, helping to speed up Windows 10.
