1. Use Lightweight Applications or Online Software
Try using lighter applications or online software to replace heavier desktop programs. If your computer struggles to run Photoshop, consider using a smaller application like Paint.NET for basic editing. Only open Photoshop when necessary. Alternatively, you can use Photoshop online.
Also, pay attention to the programs you have open. Close any software you're not actively working on. Mark frequently used browser tabs as a way to save on RAM.
Windows provides tools to show your RAM usage. To check, open Task Manager by searching for it in the Start menu or using the shortcut Ctrl + Shift + Esc. The graph at the bottom will show how much RAM is available. Sort by Commit (KB) to see which software is consuming the most RAM.


2. Remove Malware
Enable malware scanning programs on your computer to eliminate malicious software or code that may be draining resources and consuming your available RAM.
To keep your computer secure, always have an up-to-date real-time antivirus tool. Free programs like Avira Antivirus Free Edition and Bitdefender Antivirus Free Edition are popular choices. You can also consider using OpenDNS (free) to block harmful sites. If you frequently use high-risk websites, consider running your browser in sandbox mode to prevent malware attacks. Some antivirus programs like Codomo support sandboxing, or you can use third-party services like Sandboxie for free.
Additionally, it's important to monitor your online accounts, such as banking, email, and social media accounts. Change your passwords immediately if you notice any suspicious activity, as some malware can steal credentials. If your computer is set to automatically back up files or systems, be sure to scan for viruses regularly to prevent accidental infection. Online systems usually only scan the C drive, so if the virus scan isn't effective, delete old backups and reinstall the software to start saving fresh copies.


3. Sử dụng Disk Cleanup

4. Disable AutoPlay for External Devices
In addition to the risk of virus infections from the internet, external storage devices like USB drives and external hard drives are also common sources of malware. If you've noticed, every time you connect an external device to your computer, Windows automatically opens a task selection window or launches files from the device. This is the fastest way for malware to spread from external devices to your system.
Enabling AutoPlay for devices such as USB drives, memory cards, and external hard drives can put your computer at risk of viral infection. To protect your system, it’s advisable to disable the AutoPlay feature for external devices. To do this, follow these steps:
- Step 1: Click on Start > Select Settings.
- Step 2: Choose Devices.
- Step 3: In the AutoPlay tab > Set the option 'Use AutoPlay for all media and devices' to Off.


5. Add More RAM to Your Computer
If you want to fully address your computer's RAM issue, upgrading your RAM is the solution, either by adding more RAM sticks or using higher-capacity ones. This will save you the hassle of constantly monitoring your RAM usage or cleaning up memory regularly.
However, not all laptops can be upgraded with additional RAM. For example, some laptops only have a single RAM slot, meaning you'll have to replace the existing RAM entirely. If your laptop has 4GB of RAM with two 2GB sticks and you want to upgrade to 8GB, you’ll need to replace the current RAM with two 4GB sticks or one 8GB stick.
Before upgrading, make sure you check how many RAM slots your laptop has to ensure an accurate upgrade plan and avoid purchasing two RAM sticks when only one can be installed. Additionally, if your computer is too old, upgrading RAM may not solve the problem. In such cases, consider upgrading to an SSD instead of an HDD for better performance!
If your computer is running a 32-bit version of Windows, the system will only recognize up to 3GB of RAM, meaning no matter how much RAM you add, the system won’t fully utilize it. Therefore, after upgrading your RAM, make sure the operating system supports it. If you want to use more than 4GB of RAM, switch to a 64-bit operating system.
Also, check if your system has a RAM limit set during boot-up. If it does, turn it off, as it might prevent your computer from recognizing the full RAM capacity. Although upgrading RAM may not always yield dramatic results, if you want your computer to run faster without spending too much, don’t overlook upgrading your RAM.


6. Remove Unused Programs
Over time, as you use your computer, you may have installed numerous programs and applications to meet your work needs. However, installing too many utilities on your system can cause it to slow down, especially if you’re using a machine with lower specifications. Now, if you want to lighten up your computer and clear some space for other useful applications, it’s time to uninstall programs you no longer need.
Some applications are pre-installed by Windows, and removing them can free up space for more essential apps. To make room for other programs to run more smoothly, it’s recommended to delete unnecessary or rarely-used apps that were installed by default on your machine.
Follow these steps to uninstall programs:
- Step 1: Click on Start > Select Settings.
- Step 2: Choose Apps.
- Step 3: Under App & features > Select the app you want to remove > Click Uninstall.
It’s important to note that this guide isn’t just for those with lower-spec computers. Even users with high-performance machines can benefit from uninstalling unnecessary tools that may have been accidentally downloaded or no longer wanted, or perhaps to clear space for more useful programs.


7. Disable Unnecessary Startup Programs
After your computer starts up, certain programs will automatically launch as soon as you log into your operating system. These include both system software and third-party applications installed by the user, which are set to open automatically every time the computer is turned on. However, you can disable these auto-start programs to speed up your system.
The main reason your computer may be slow to start is because of all these programs launching simultaneously. To resolve this issue, follow these steps:
- Step 1: Click Start Windows > Select Settings.
- Step 2: Choose Apps.
- Step 3: In the Startup tab > Click the On/Off icon to enable or disable programs that start with Windows.

- Step 2: In the Task Manager window, click More details.
- Step 3: Then click on the Startup tab.
- Step 4: Right-click on the programs you want to stop from starting with Windows 10, and click Disable.
To remove startup programs from the Startup folder: Shortcuts for programs that start with Windows are stored in the Startup folder. You can delete these shortcuts to prevent the programs from launching with your system:
- Step 1: Open the Run window by pressing Windows + R.
- Step 2: In the Run window, type shell:startup and press Enter to open the Startup folder.
- Step 3: Select the shortcut of the program you want to remove from the startup, and press Delete to remove it.


8. Scan for Viruses and Malware
Computer viruses can significantly reduce the performance of your laptop or PC. It may also be caused by the installation of pirated third-party software that has hijacked your system's resources. Therefore, using the best antivirus software is essential to identify and prevent any malicious activities that could harm your PC while freeing up RAM.
When a computer is put into use, viruses are inevitable. They can spread through various channels: the Internet, external devices like USB drives, hard drives, CDs, and more. Different types of viruses come with varying degrees of damage. Once a virus infects a system, it can slow down the machine, corrupt infected files, delete data, or cause system errors. Some viruses even use the victim’s computer to form a botnet—a network of compromised computers—to launch attacks on other servers or websites.
When a computer is infected, it can be extremely frustrating for the user. It can also compromise information security by stealing personal data, login credentials, credit card numbers, and more. To protect your system, it's crucial to regularly update and scan for viruses using the latest antivirus software, reducing the risk of virus infections and boosting your computer’s defenses.


9. Stop Background Applications
One common way to speed up a computer is by disabling background apps that run in the system, in addition to using other methods. This helps free up resources and storage, leading to better stability and faster performance. This applies not only to Windows 10 but also to Windows 8 and 7, where running background applications can negatively impact the system. Especially when using a computer for long periods without blocking background apps, it can result in slow startup times and sluggish performance. The following guide will help you learn how to disable background apps on your PC.
Before disabling all background applications, here are a few things to keep in mind:
- Turning off background apps won’t prevent those apps from functioning. You can still launch and use them when needed. This only stops the apps from downloading data, using CPU/RAM, or draining battery when you're not actively using them.
- When an app is disabled, you won’t receive notifications or see any updates from it, such as news in the Start menu tiles or notifications.
- Some apps rely on running in the background to provide essential services. For example, if you disable the Alarm app, your alarm won’t ring when set. Of course, if you have a reliable alarm clock, you can safely disable the Alarm app. It all depends on your preferences and how you use the apps.
To disable background apps, follow these steps:
- Step 1: Open Settings > Select Privacy.
- Step 2: Choose Background apps > Toggle the switch at 'Let apps run in the background' to turn off all background apps or select specific apps that can run in the background based on your needs.


10. Disable Visual Effects on Windows
Microsoft has equipped Windows with a variety of window transition effects to make the operating system visually appealing. However, these features can sometimes become frustrating, especially when they cause delays in closing, maximizing, or minimizing windows. If desired, you can easily disable these options across modern versions of Windows, including Windows 7, 8, and 10.
How can you disable Windows animations? This is a question many Windows users have. If you're using Windows 10 or Windows 8.1 and want to turn off the animation feature, it can be done with ease. Animations are nice to have around when you let your kids play on the computer, for example. But if you're trying to get work done, the animations in Windows 10 and Windows 8.1 can be distracting. In fact, you may end up spending more time on your tasks than you'd like. Here's how to disable visual effects:
- Step 1: Open the Control Panel, select System > Click on Advanced system settings.
- Step 2: Under the Advanced tab, click Settings > In the Visual Effects tab, choose Adjust for best performance (Alternatively, you can select Custom to enable/disable individual visual effects as you prefer).
Your computer will run faster when you select Adjust for best performance, but the display may appear somewhat blurry, which could strain your eyes if you're frequently working in this mode.


11. Update Software on Your Computer
Software updates (Firmware Updates) involve downloading new versions of software that integrate improved features or fix existing issues. Some manufacturers release updates periodically. Once updated, your computer will run more smoothly and be more stable, as the bugs from previous versions are mostly resolved, and your device's security is enhanced.
When you receive a notification for a software update, it indicates that the old version has started to experience issues and is less stable on your system. Therefore, updating to the new version is a good idea to fix those issues and improve your user experience.
However, it’s important to note that if a company releases a new version but doesn’t require you to update yet, you don’t need to rush. This likely means that the old version is still the most stable on your system. Updating could sometimes lead to unexpected errors.
It’s recommended to always use the latest version of software/apps available on your computer. Older software versions may use up more RAM, causing your computer to slow down.


12. Set Up Virtual RAM
Virtual Memory is a feature developed by Microsoft for Windows operating systems that allows users to utilize a small portion of free hard drive space as virtual RAM, helping speed up processing when needed. There are two main types of memory on a computer: storage drive (HDD or SSD) and RAM. The storage drive holds all your personal data, while RAM stores a certain amount of data from the programs you have opened.
If you use all available RAM for your system, it will optimize the virtual memory, also known as the Paging File, temporarily expanding the RAM to run the programs you require. The size of the virtual memory is the amount of space you set from the storage drive to allow RAM to function more efficiently. Virtual RAM is extremely helpful if you need to handle a large amount of data from several running programs.
However, custom virtual RAM set from a hard drive (including SSD) will perform slower than actual RAM. When the system runs low on RAM, the Paging File appears, and some data stored in RAM will move to this file to free up space for features requiring more memory.
Here’s how to set up virtual RAM:
- Step 1: Open the Control Panel, select System > Select Advanced system settings.
- Step 2: Under Advanced, select Settings > Go to the Advanced tab, click Change...
- Step 3: Uncheck Automatically manage paging file size for all drives > Enter the amount you want to set for virtual RAM under Custom size, for example, 4096 MB (4 GB), with a maximum of 7168 MB (7 GB) > Click Set > Click OK


13. Restart Your Computer
Restarting your computer will clear the memory and reset all running programs, freeing up any background processes that may be consuming your RAM. You should restart your computer regularly to free up RAM, especially if you use your computer frequently.
A restart is often necessary when the computer is slow, frozen, or after installing new software. There are various ways to restart your computer, and aside from using the Start button, you have multiple options depending on the situation.
Let’s explore some of these restart methods:
- Using the Windows shortcut is the quickest way to restart your computer. Press Windows+M (to minimize all open windows), then press Alt+F4 (to bring up the shutdown menu), and select Restart. If you have no programs running or have closed/minimized all open windows, just pressing Alt+F4 will suffice.
- Create a shortcut to restart your computer: This method saves you time with fewer clicks each time you need to restart. First, right-click on the Desktop and select New > Shortcut. Then enter the following in the Location field: shutdown.exe -r -t 00 -f
- Restart to access BIOS: Typically, to access BIOS when your computer starts, you’ll need to quickly press F2 or Delete on the boot screen. However, with computers using solid-state drives (SSD), the boot time is reduced to just a few seconds.
- Use Task Scheduler: You can set a specific time for your computer to restart automatically. First, open the Start Menu and search for Task Scheduler.
