Has your PC become slow over time? Before thinking about hardware modifications, try some remedies to make it more responsive with the tools built into Windows as standard.

Whatever its operating system, after a few years of use, a computer begins to slow down, especially if you use it daily and install a lot of applications. Startup becomes slower, applications take longer to launch and are less responsive, even turning off the machine seems impacted. Several very different causes generate this phenomenon.

One of the main reasons is that the system – in this case, Windows on a PC -, your applications (your Internet browser, for example) and the services Web that you use have experienced multiple updates, which add functions or make them safer to use, and which in any case require more hardware resources – a faster processor, more RAM, more storage space, better Internet and Wi-Fi connection. To obtain a significant performance improvement – ​​even a real boost – the best way is to replace certain components with equivalent newer, more powerful or faster, by increasing the random access memory (Ram) or by exchanging the hard disk for an SSD, for example

However, without any hardware investment, whether you’ve experienced a gradual overall PC slowdown or a more recent, sudden slowness, a major cleanup and the use of system tools provided by Windows 10 can improve the situation to some extent. These are the free remedies that we suggest you apply in this practical sheet, before possibly moving on to a material phase.

As always, we still advise you to follow a proven principle: if it ain’t broke, we don’t fix it! In other words, if your PC is not exhibiting the symptoms discussed in one section, skip ahead to the next section to find other possible causes for the slowdown.

How do I check that Windows is up to date?

While in very rare cases a Windows update is causing concern for some users, in the vast majority of cases system updates are beneficial! And they can also fix an old or recent problem that is slowing down the machine, so that’s one more good reason to apply these updates.

  • Click on the Start button, then on Settings, then on Update and Security, then in the left column on < strong>Windows Update, and finally the Check for updates button.

  • If Windows says “Updates are available”, click Install Now.
  • Select the updates to install (or leave it to Windows) and click Install.
  • Restart the computer to see if it works better.

How to check Windows system disk status?

A damaged or full disk is a possible cause of Windows slowing down. Start with these two quick checks.

Verify that the Windows disk is not damaged

The case is unlikely, so you might as well rule out the hypothesis quickly. A simple scan of your computer’s storage media, especially the disk where Windows is installed, will only take a handful of seconds, at worst a few minutes. This handy sheet explains how to run a quick or advanced scan and attempt, if necessary, a repair.

Check how much free disk space is left on the PC

One of the possible sources of slowdown is the lack of space on the Windows disk, we will explain why later. Start by checking what it is…

  • Press Windows + E keys to open Windows 10 File Explorer.

  • Click This PC in the left column. For each disk or storage space available, a gauge shows you the occupancy rate.
  • The gauge is blue? Everything is fine so far.
  • The gauge is red? The situation becomes critical, even more so if it is the C: drive on which Windows is installed. We must act…

How to free up disk space in Windows?

Keeping free space on the C: drive is essential, at least 10-15%. First, because to multitask the system and several applications at the same time, Windows often needs more memory space than your PC’s RAM has (from 2 GB to 16 GB). Windows therefore reserves a space of one or more gigabytes on your hard drive – this space is called the “exchange file” or swap file – space which it uses as “virtual memory” in which it stores temporarily data from RAM.

That’s not all. Windows and your applications continually create temporary files on C: to make their work easier. Without free space on this disk, performance may suffer or even crash. This will be particularly the case if you have stored countless files that consume a lot of space (videos, photos and images, music, etc.), or if you have purchased an ultralight and affordable laptop PC that only carries 32 GB or 64 GB of storage.

In this section, you will learn how to clean the Windows disk by intervening on four elements:

  • Windows 10 Storage Sense
  • System and temporary files
  • Documents and media files
  • Useless applications

If the Windows disk isn’t full—say, 60% full—you probably won’t experience any improvement in performance. Cleaning up the disk a bit isn’t a bad thing, though. You can also apply some of the following tips on disks other than the one where Windows is installed.

Use Windows 10 Storage Sense

The Storage Sense helps free up space on your drives by deleting unnecessary or temporary files. It will therefore be very useful if the C: drive is full. You can activate it punctually or ask it to act automatically, when you run out of disk space or at regular intervals.

  • Click the Start button > Settings >System, and in the left column on Storage.

  • Windows 10 Storage Sense shows items saved on the C: drive by broad categories.
  • Click Temporary Files.
  • After a few moments, Windows suggests deleting some of the temporary files that take up the most space on your PC. If in doubt, only delete those whose box is already checked. Press the Delete files.
  • button.

  • Files are sent to the Recycle Bin, you will need to empty it to gain the promised disk space. The Recycle Bin is located on the Desktop, right-click its icon to Empty Recycle Bin.

  • In the Storage Wizard, also click on the blue text Show more categories.
  • Select other categories (Documents, Music, Videos…) to consult their contents and see if files belonging to you should be deleted or saved on another disk (see later the section Transferring documents…).
  • To clean up drives other than C:, go to the bottom of the Storage Advisor window and click on the blue text Show storage usage on other drives< /strong>.

Automatically launch Storage Wizard

  • At the very top of the Storage Wizard window, click the blue text Configure Storage Wizard or run it now.

  • The Assistant can automatically delete temporary files (there is no risk) but also files in your Downloads folder. There, we are more reluctant, because some files may still be useful to you. Unless you are sure of yourself, keep the choice “Never” and clean it yourself from time to time, manually, in this Downloads folder.
  • You can already press the Clean now button at the bottom.
  • By clicking on the switch at the top, activate the automatic launch.
  • Specify the frequency, for example When disk space is low.

Save apps, documents, and media files to a disk other than Windows

If your C: drive has enough disk space, you don’t need to get yourself into trouble, skip to the next tip!

On the other hand, if the case has just arisen, it is possible that the C: drive is full again in a few days or weeks. And once again slows down your PC. Windows 10 Storage Sense allows you to save new apps you install, new documents you create, music, photos, and videos to a drive other than Windows in the future. If the computer has two storage media (an ultra-fast SSD or eMMC disk for the Windows system, and a larger internal hard disk for data and apps), the situation is obviously simpler. Otherwise, applications and documents will have to be stored on removable storage.

  • If you activate the option that we are going to see, choose an internal storage medium or one that will remain plugged in all the time or in any case always at hand to reconnect it easily, even when you travel with your laptop .
  • If it is a mini memory card (in the case of an ultralight laptop), a microSD card stamped Class 10 or U1 or U3 will offer better performance than other models, for a fairly negligible price difference.
  • If you’re going for USB storage, ideally you should choose a USB 3 external hard drive or a USB 3 memory stick. Read/write operations will be three to five times faster in USB 3 than ‘in USB 2. The trick is not 100% reliable, but look at the socket of the USB stick or external disk cable: the plastic inside the socket should be blue > if it is a USB 3 socket.

  • It is not enough to have a USB 3 memory key or an external USB 3 disk to go to the speed of USB 3: on the PC, it is also necessary to plug this peripheral into a USB 3 socket. Otherwise, you’ll go at USB 2 speed! It’s not serious, but it’s slower. However, most laptops (not Macs) mix USB 2 sockets (to connect a mouse, for example) with one or more USB 3 sockets (sometimes there is only one). The USB 3 socket on computers can be identified either by the blue plastic inside or by the words SuperSpeed ​​or SS-USB etched next to the socket.
  • In Windows 10 Storage Sense, click on the blue text Change where new content is saved.

  • Select a drive for each category to save new content to. You’ll make your life easier by choosing the same disk for all items. And please note that these are new items, not existing ones.

Clean system and temporary files

If your version of Windows doesn’t have Storage Sense or you don’t want to use it, here’s another way to do it. Again, this technique will only have a real effect on performance if your computer’s C: drive starts to get full.

  • You must log in to Windows with an Administrator account to launch the system tool on the C: drive of the computer.
  • Display File Explorer (Windows + E keys), right-click on the C: drive and then on Properties .

  • Press the Disk Cleanup button.

  • The Disk Cleanup window tells you on the first line the total space that you could free up on this disk by checking all the options. When that space is expressed in GB (gigabytes), it’s worth it.

  • In the list below, you can generally tick all the proposals. Don’t cry victory though, some files deleted here will be gradually recreated and will bloat, for example the thumbnails of your images and videos that Windows keeps to display the folders you are viewing more quickly.
  • The Total Space Gained area tells you how much space will be freed up based on the checked boxes.
  • The Description area and the View Files button (available for certain categories only) provide information about each category. You won’t risk making Windows unstable by checking one.
  • Press the Clean up system files button to save space.
  • You can find more tips for deleting Windows 10 temporary system files in this how-to sheet.

Transfer documents from Windows disk to another disk

The above automatic cleanup tool only deals with Windows system files. It goes without saying that if the Windows disk is full, you will also have to clear it of all your personal files and documents which are not immediately useful to you. Back them up on a medium that you believe to be reliable: a second internal computer disk, or an external hard disk, a USB key, a small memory card.

  • You should make automatic backups of your documents on a daily basis. Follow the advice of this practical sheet.
  • To free up a lot of space, start with videos, images, photos and music, which take up a lot of space on your disks. No need to hope to save space by compressing them in a Zip or other archive, these media files are already all compressed.
  • Also see the contents of your Downloads folder, which may contain files to delete or move to external storage.
  • Copy documents to another storage medium and only delete originals when you are sure you have made a copy.
  • Only transfer documents. Unnecessary applications must be uninstalled (see below). And to move one from one disk to another, in Windows, you have to uninstall it and then reinstall it.
  • To facilitate document transfers from one disk to another, display two folders side by side: open two File Explorer windows (Windows+E) and in one of them, navigate to the documents folder of the C: drive to transfer, for example your Documents folder. Press the two Windows+Left Arrow keys on your keyboard.

  • Windows places this first folder window on the left half of the screen and presents you with thumbnails of other open folders and applications on the Desktop on the right. Click on the thumbnail of the second folder… Your two folders take up the whole screen, side by side, to facilitate cutting/pasting and moving files.

If installed applications or games no longer interest you, uninstall these programs to free up space, especially if they are installed on the already full Windows hard drive C:.

An important point: whether the disk is full or not, if the PC manufacturer has provided Windows with paid antivirus or security software that displays an alert message each time the PC is started PC because you do not pay the annual subscription, we advise you to uninstall this software: it no longer protects you effectively since you do not pay the subscription, it slows down the PC unnecessarily (and sometimes a lot!), and it additionally may prevent Windows 10’s built-in antivirus and firewall from activating. To summarize, either you pay the subscription or you uninstall.

  • To uninstall an application, click the Start button at the bottom left of the screen.
  • Click on Settings.
  • If you don’t see the Apps icon in Settings, click Home in the left column to return to the main screen.

  • Click on Apps.

  • Click on the app in the list, then on the Uninstall button.

How do I disable apps that launch at Windows startup?

Even if you don’t want to uninstall an application, you don’t have to leave it running each time you start the PC, which slows down the launch, takes up unnecessarily RAM and even becomes annoying if a message is displayed at each start. To modify the list of applications that launch at startup, the procedure varies depending on your version of Windows:

  • With newer versions of Windows 10 (versions 1803 or higher), click the Start buttonand then click Settings> Apps> Startup. Under each application that you disable or enable with a click of the switch, Windows tells you the estimated impact (low, medium, high) on PC boot time.

  • In older versions of Windows, type the two-key combination Windows+R.
  • In the Run window, type msconfig and press the OK button.

  • Click on the Startup tab. Older versions of Windows display here the list of programs that launch and that can be unchecked.
  • In Windows 10, under the Startup tab, click the blue text Open Task Manager.
  • To disable or re-enable an item, right-click it. The Startup Impact column tells you if the PC will start up faster.

  • In any case, uncheck the programs that are not essential for you to start, for example PowerDVD or LibreOffice…
  • … but keep all protection software checked like antivirus and firewall. Retain the Wi-Fi recognition program and some software for keyboards, mice and touchpads if necessary.

How to identify an application that is freezing or slowing down Windows?

If your computer suddenly slows down, find out which application is the culprit. If it appears to be stuck and consuming all the resources of the PC’s processor, you can destroy it. But reserve this method for situations where it is not possible to cleanly close the application, because all files opened and modified in the application will not be saved.

  • Type the three-key combination Ctrl + Alt + Del and from the menu choose Task Manager.

  • The Processor and Memory columns tell you which apps are consuming the most resources. A click on a column name (for example Processor) allows you to sort the tasks according to this criterion (click on the Name column name to return to the initial presentation).

  • The Internet browser (Edge, Chrome, Firefox…) often takes up a lot of space in RAM, especially if you have opened many websites in tabs. If RAM starts to run low, return to the browser and close unnecessary tabs. Sometimes it’s not enough to recover RAM. In this case, after closing the superfluous tabs, quit the browser and then relaunch it.
  • If Windows considers an application to be blocked, its name is followed by (Not responding). Wait a bit anyway and if the situation does not change, right-click on the name of the application and choose End Task.
  • It is better to only intervene in the list of Applications, without touching the Processes in the background. Note that some system processes automatically restart if you kill them.

What should I do if my PC slows down due to a recent hardware or software installation?

Sometimes a computer starts to malfunction or slow down after installing software or new hardware (expansion card, peripheral, etc.).

Uninstall the offending software

  • Whether it’s an application, game or system software (utility or device driver), uninstall it if possible (as explained above) and restart the computer. If this is not possible or if it does not solve the problem, try the following method.

Restart the PC in safe mode

  • If the culprit is a device, such as a printer, and uninstalling its driver program isn’t enough, start the computer in safe mode and see if a a simple normal restart is not enough to solve the problem. If that doesn’t fix the problem, try the following method.

Restore Windows from a System Restore Point

  • See if Windows created a restore point before installing the device or application, in which case restore Windows to an earlier situation. Find all our tips here.

What to do if the Internet or Wi-Fi connection is slow?

If the Wi-Fi connection is less good when you move from one room to another, here are some tips:

  • If possible, move your computer around the room to try to better capture the signal from your Internet box.
  • Elevate the Internet box at least 1 meter above the ground and if possible limit obstacles that reduce the signal.
  • Buy a Wi-Fi repeater (from 30 euros) to boost the signal in parts of the house with poor or no coverage.
  • Share your smartphone’s 4G connection occasionally, but don’t overdo it! You risk very quickly consuming all the monthly quota provided for by your mobile plan (for example 20 GB) and paying additional costs. On iPhone, go to Settings > Cellular Data or Settings > Connection Sharing. On Android, depending on the smartphone, the tethering option can be found in Settings > Network & Internet or in Settings > Login & sharing or in an option to create a mobile Wi-Fi hotspot. Once the 3G/4G connection has been shared via Wi-Fi on your smartphone, connect to this Wi-Fi network on your Windows PC. Don’t forget to turn off sharing on the smartphone after use.

How do I check for viruses or malware that slows down the PC?

The slowdown may be caused by malicious programs installed on the computer without your knowledge. Since the options vary slightly depending on your version of Windows 10, we provide several methods.

To find your version of Windows, click the Start button > Settings > System > System Informationor About.

Scan for viruses via Windows Security

This method is for Windows 10 version 1809 or later.

  • Click the Start button > Settings > Update and Security > Windows Security and select Open Windows Security.
  • Click Virus & threat protection, then under Virus & threat protection updates, click the blue text Check for updates.
  • To get the most recent updates, on the Protection updates screen, click Check for updates.
  • Under Current Threats, click Quick Scan.

  • If the Quick Scan does not report anything, you can click on the blue Scan Options text and run a Full Scan, which may take more than a hour.

Scan for viruses via Windows Defender Security Center

This method is for Windows 10 version 1803.

  • Click the Start button > Settings > Update and Security > Windows Security and select Open Windows Defender Security Center.
  • Click Virus & Threat Protection Updates > Check for updates to get the latest virus and malware definitions.
  • Under Virus & threat protection, click Scan now.
  • If the quick scan doesn’t report anything, you can try an advanced scan, which will take longer.

Scan for viruses offline via Windows Defender (method 1)

Attempt to run Windows Defender offline if Windows Security does not open, or fails to update the malicious file definition file, or fails to complete virus scanning . The method below is for Windows 10 version 1809 or later.

  • Close all your applications and documents because Windows will restart.
  • Click the Start button > Settings > Update and Security > Windows Security and select Open Windows Security.
  • Click Virus & Threat Protection, then under Current Threats, click the blue text Scan Options. Check the Windows Defender Offline Scan box and press the Scan Now button.

The computer restarts to check for malicious programs for about fifteen minutes and then restarts once the analysis is complete.

Scan for viruses offline with Windows Defender (method 2)

Attempt to run Windows Defender offline if Windows Defender Security Center does not open, or fails to update the malicious file definition file, or does not terminate the search for viruses. The method below is for Windows 10 version 1803.

  • Close all your applications and documents because Windows will restart.
  • Click the Start button > Settings > Update and Security > Windows Security and select Open Windows Defender Security Center.
  • Click Virus & threat protection, then Run another advanced scan > Windows Defender Offline Scan > Analyze now.
  • The computer restarts to scan for malware for about 15 minutes and then restarts once the scan is complete.
