How to boost your PC?

Accumulation of programs, lack of updates, malware … There are many reasons why your PC can gradually become slow. Want to boost your PC? Follow these 13 tips! 

Remove programs at startup

Often, because of the programs and tools installed, computers start more slowly. Most programs start when you start Windows when you probably do not use it.

To prevent them from launching automatically: go to your taskbar at the bottom right of your screen. Click the white arrow pointing up to display the notification icons.

Each icon represents a program that starts at startup. Some are essential as antivirus, but others are not.

Right-click each one, then Settings (if available), and uncheck the box.

In our example: Automatically launch OneDrive when I open a Windows session.

Google Drive is one of the programs that can be started manually when you need it.

To disable all other programs and wizards that start when you open Windows:

  • Simultaneously press the Windows keys (logo on your keyboard) + R

  • Type MSConfig in the window that opens, and then click OK.
  • Click the Services tab, and clear the checkbox at the bottom of hiding all Microsoft services.

For example, Firefox works very well without the Mozilla Maintenance service.

In Task Manager – which you open by right-clicking on the taskbar and then selecting Task Manager – you will see that there are many programs running at the same time as Windows.

To help you know which ones to disable, do a search on Google.

Right-click the program and select Online Search. Thanks to this information, you will know better if these programs are really useful to you.

To disable each program, right-click it and select End Task.


Windows also show you what impact each program has on its performance.


Recent versions of Windows automatically defragment the disk, but do so in a rather rudimentary way.

You will find on the market very good defragmentation software that can boost the performance of your computer.

The German software O & O Defrag (translated into French) is one of them. Otherwise, you have Advanced SystemCare 10 from IObit, quite powerful and above all free.

Small warnings:

  • Do not use this software if you have an SSD.
  • If you have an SSD as well as a hard drive, only the latter must be defragmented.

Spot malware

It is recommended to scan your system to identify any slowdown or malfunctioning threats.

If you protect your computer with Windows Defender:

  • Go to the Start menu (Windows icon, bottom left of your screen).
  • Then, Settings, select Update and Security.
  • On the left, select Windows Defender.
  • Select the analysis: Complete.
  • Then, click Scan Now.

If Windows sees something, you will be alerted and a solution will be offered.

If you use another paid (or free ) antivirus, such as AVG, Norton, Mc Afee, you will need to start it and find the option to scan your system.

Taming virtual effects

Windows 10 has a very nice and responsive design with great visual effects. Unfortunately, these effects can affect the performance of older PCs, so it is better to disable them.

Here’s how to do it:

  • Open the Start menu and type Advanced System Settings, and then press Enter at the first result.
  • In the window that opens: Performance section, click Settings. A list of visual effects is displayed on the screen.
  • You can uncheck those that seem superfluous.
  • Otherwise, just select the Adjust option to get the best performance, and finally Apply.

Reinstall Windows

Reinstalling Windows is another very good way to boost your computer.

It removes software that can slow down your PC, adware (adware embedded in free software), malware, temporary files, etc.

A Windows Recovery CD is required for versions prior to Windows 8 and 10.

On Windows 8 and 10, the Refresh option is integrated. It reinstalls Windows without erasing your personal folders, so no upstream backup is needed.

In Windows 8:

  • fiche the Charm Bar, positioning your mouse on the right of your screen or via the shortcut Win + C.
  • Click Settings, and then click Change settings for this PC.
  • Click Update and Security →  Recovery  Refresh Your PC Without Affecting Your Files, then Start.

In Windows 10:

  • In the Start menu, click on the ” gear ” icon.
  • Select Update and Security, on the left select: Recovery.

  • Click Reset this PC, and then Start.
  • The Refresh window displays 2 options: Keep my files and Erase everything.

We recommend this method because it is automatic and easy.

Important note: If you choose to completely reboot Windows, you must absolutely copy all your files to another device such as an external hard drive or a USB key.


Update drivers, programs and Windows

Drivers, outdated programs, and Windows itself can slow down your PC.

For example, drivers can prevent the Windows system from shutting down or slowing down. So you need to update your system.

Windows updates are done automatically.

You can manually check which ones have been executed:

  • Go to the Control Panel.
  • Programs and Features  Installed Updates. 

Drivers allow Windows to access hardware components such as video, sound, printer/scanner, webcam, and more. 
Before updating them, to correct some bugs and boost the performance of your PC, it is important to identify their model and consult the website of the manufacturers.

To update them:

  • Go to Start  Settings  Connected Devices on the left.      
  • Click Device Manager at the bottom of the window.
  • Click the arrow in front of the device to deploy a list.
  • Then, right-click on the driver.
  • Click Update Driver
