How to Make Your Windows 11 PC Faster: 15 Proven Ways to Improve Performance

Is your Windows 11 PC running slowly? Does it take forever to start, freeze when you open applications, or struggle to handle multiple browser tabs? You are not alone. A slow computer is a common problem that can affect students, remote workers, gamers, and everyday users.

The good news is that you may not need to buy a new computer to improve its performance. In many cases, unnecessary startup programs, limited storage space, outdated software, excessive background activity, or incorrect power settings can make Windows feel slower than it should.

Learning how to make your Windows 11 PC faster can help you identify the cause of the problem and apply practical solutions without spending money on unnecessary software.

In this guide, you will discover 15 ways to speed up Windows 11, improve startup times, reduce unnecessary background activity, free up disk space, and troubleshoot common performance problems.

These methods use built-in Windows features whenever possible. You can try them individually and check whether each change improves your computer's performance.

Important: Not every slow computer has the same problem. Start with the simplest solutions and avoid changing advanced system settings unless you understand their purpose.

Why Is Your Windows 11 PC Running Slowly?

Before trying different optimization methods, it helps to understand why your computer might be slow.

Windows 11 performance can be affected by several factors.

Too Many Startup Programs

Some applications automatically launch when you sign in to Windows. If many programs start simultaneously, your computer may take longer to become responsive.

These applications may also continue running in the background and consume memory or processing resources.

Low Disk Space

When your system drive is nearly full, Windows and your applications may have less room for temporary files, updates, and other operations.

Removing unnecessary files can help restore available storage space.

Too Many Background Applications

Applications running in the background can consume CPU resources, memory, network bandwidth, and battery power.

If your computer has limited RAM, running many applications simultaneously can make switching between windows noticeably slower.

Outdated Software or Drivers

Windows updates and device-driver updates can include performance improvements, compatibility fixes, and reliability enhancements.

However, an update is not guaranteed to solve every performance issue. The underlying cause still matters.

Malware or Unwanted Software

Malicious software can consume system resources, interfere with normal operation, and create security risks.

If your computer suddenly becomes slow, checking for malware is an important troubleshooting step.

Aging Hardware

Older computers may struggle with modern applications, especially when they have limited memory, a slow hard drive, or a processor that no longer meets current workloads.

Software adjustments can help, but they cannot eliminate every hardware limitation.

Now, let's look at the most useful ways to improve Windows 11 performance.

1. Disable Unnecessary Startup Apps

One of the easiest ways to make Windows 11 faster is to prevent unnecessary applications from launching automatically.

Many programs add themselves to the startup list during installation. Examples may include messaging applications, game launchers, cloud utilities, and software updaters.

Some are useful, but others do not need to run every time you turn on your computer.

How to Disable Startup Apps

Follow these steps:

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Select Startup apps in the sidebar.
3. Review the applications listed.
4. Look at the startup impact information when available.
5. Right-click an application you do not need at startup.
6. Select Disable.

Repeat this process for other nonessential applications.

Be careful not to disable security software or utilities that your computer needs to operate correctly.

Disabling a startup application does not necessarily uninstall it. You can still open the application manually whenever you need it.

Which Startup Apps Should You Disable?

Consider disabling applications that you rarely use and do not need immediately after signing in.

For example, you may not need a game launcher to start automatically if you only play games occasionally.

However, applications used for essential backups, security protection, accessibility, or device functions may need to remain enabled.

Expected benefit: Your computer may start more quickly and become usable sooner after you sign in.

The actual improvement depends on which applications are running and how much system resources they consume.

2. Free Up Disk Space

A nearly full system drive can contribute to Windows performance problems and make updates more difficult to install.

Removing unnecessary files is a practical way to improve storage availability without purchasing additional hardware.

Windows 11 includes several tools that can help.

Use Temporary Files Cleanup

To remove temporary files:

1. Open Settings.
2. Select System.
3. Choose Storage.
4. Select Temporary files.
5. Review the categories displayed.
6. Select the files you want to remove.
7. Click Remove files.

Review the selections carefully before confirming.

For example, the Downloads folder may contain files you still need. Do not select a category simply because it appears in the cleanup list.

Enable Storage Sense

Storage Sense can automatically remove certain unnecessary files when your computer needs additional storage space.

To configure it:

1. Open Settings.
2. Select System > Storage.
3. Open Storage Sense.
4. Enable the feature.
5. Review its available cleanup settings.

You can configure Storage Sense according to your preferences.

If you use your Downloads folder to store important documents, make sure its cleanup settings will not remove files you intend to keep.

Remove Large Unnecessary Files

You may also have large videos, old installation packages, duplicate downloads, or archived files that you no longer need.

Review your personal files before deleting anything.

If you want to keep them but do not need immediate access, consider moving them to an external drive or another trusted storage location.

Expected benefit: Freeing disk space can help Windows manage updates and temporary files more effectively. It may also improve responsiveness when low storage is contributing to the slowdown.

3. Uninstall Applications You No Longer Use

Unused applications can occupy valuable storage space. Some may also install background services or startup components.

Removing programs you no longer need can simplify your system and reduce unnecessary activity.

How to Uninstall Unused Apps

1. Open Settings.
2. Select Apps.
3. Choose Installed apps.
4. Review the installed applications.
5. Find a program you no longer use.
6. Select the three-dot menu beside it.
7. Choose Uninstall, if available.
8. Follow the instructions to complete the process.

Repeat these steps for other unnecessary applications.

What Should You Remove?

You might consider uninstalling:

• Old applications you no longer use.
• Expired trial software.
• Games you no longer play.
• Unnecessary third-party utilities.
• Applications you installed temporarily for a specific task.

Avoid uninstalling unfamiliar system components simply because you do not recognize their names.

Some applications support hardware functions, security tools, or other software you rely on.

If you are unsure about a program, research its purpose before removing it.

Expected benefit: You can reclaim storage space and potentially reduce background activity.

4. Restart Your Computer Regularly

Restarting your computer is a simple troubleshooting step that many people overlook.

If your PC has been running for a long time, applications and background processes may accumulate. A restart closes running applications and gives Windows a fresh session.

Restarting can also complete certain updates and resolve temporary software problems.

How to Restart Windows 11

1. Save your work.
2. Close applications that contain unsaved changes.
3. Open the Start menu.
4. Select the Power icon.
5. Choose Restart.
6. Wait for Windows to start again.

After restarting, open only the applications you need and check whether the computer feels more responsive.

If the slowdown returns immediately, a persistent background process, software conflict, or hardware limitation may be responsible.

Restarting is not a permanent fix for every problem, but it is an easy first step.

5. Install Windows Updates

Keeping Windows updated can improve stability, security, and compatibility.

Microsoft regularly provides Windows updates that may include fixes relevant to system performance.

However, you should not assume that every update will make your computer faster. Some performance issues require separate troubleshooting.

How to Check for Windows 11 Updates

1. Open Settings.
2. Select Windows Update.
3. Click Check for updates.
4. Install available updates that are appropriate for your device.
5. Restart your computer if Windows requests it.

If you have a pending restart, complete it before judging whether the update has improved performance.

You can also review optional updates when troubleshooting a particular hardware issue.

Be selective with optional driver updates. If a device is working correctly, you do not necessarily need to install every optional update.

Tip: Keep your operating system updated through Windows Update rather than downloading unofficial system files from unfamiliar websites.

6. Update Your Device Drivers

Device drivers help Windows communicate with hardware such as graphics cards, network adapters, audio devices, and other components.

A faulty or outdated driver can sometimes contribute to poor performance, crashes, or compatibility problems.

How to Check for Driver Updates

Start by checking Windows Update:

1. Open Settings.
2. Select Windows Update.
3. Open Advanced options.
4. Select Optional updates, if available.
5. Review any available driver updates.
6. Install appropriate updates when needed.

For graphics, chipset, and other important drivers, you can also consult the official support website for your computer or hardware manufacturer.

Laptop owners should generally begin with the laptop manufacturer's support page because some systems use customized drivers.

Should You Use Automatic Driver Updater Programs?

Be cautious with unfamiliar third-party driver updater applications.

You do not need to install an unknown utility just to check for driver updates.

Using Windows Update or the official manufacturer's support tools is generally a safer starting point.

If the computer became slow immediately after a driver update, investigate whether the update introduced a compatibility issue before installing additional software.

7. Adjust Windows 11 Visual Effects

Windows 11 includes visual effects such as animations, shadows, and transparency.

These features can make the interface look polished, but reducing some effects may help older computers or systems with limited graphics resources feel more responsive.

The improvement depends on your hardware. Modern computers may show little difference.

How to Adjust Visual Effects for Better Performance

1. Press the Windows key.
2. Search for Adjust the appearance and performance of Windows.
3. Open the matching system settings dialog.
4. Select the Visual Effects tab.
5. Choose Adjust for best performance.
6. Select Apply.
7. Test your computer.

This option disables several visual effects.

If you prefer a more attractive interface, you can select the individual effects you want to keep.

For example, you may prefer to retain smoother fonts while reducing unnecessary animations.

Is Disabling Animations Worth It?

If you have an older computer, reducing visual effects may make certain interface interactions feel faster.

However, it will not necessarily improve gaming performance, increase RAM, or compensate for a severely outdated processor.

Think of this as a small optimization rather than a complete solution.

8. Change the Power Mode to Best Performance

Windows 11 offers power settings that balance performance and energy consumption.

On supported devices, selecting a performance-oriented power mode can help the computer prioritize responsiveness.

However, this setting may increase power consumption, heat, and fan noise.

How to Change the Power Mode

1. Open Settings.
2. Select System.
3. Choose Power & battery.
4. Find Power mode.
5. Select Best performance, if available.

The exact options may vary depending on your computer.

If you use a desktop PC, increased energy consumption may be less important than it is on a laptop.

For a laptop, consider using the best-performance setting when connected to power and switching to a more balanced setting when battery life matters.

Important: A performance-oriented power mode cannot overcome every CPU, GPU, or memory limitation.

It also does not guarantee a noticeable improvement during ordinary browsing or document editing.

9. Check Task Manager for Resource-Heavy Applications

If your computer is still slow, identify what is consuming its resources.

Task Manager can show which applications and processes are using CPU, memory, disk activity, and network resources.

This helps you investigate the cause rather than randomly changing settings.

How to Find Applications That Slow Down Your PC

1. Press Ctrl + Shift + Esc.
2. Open the Processes tab.
3. Review the CPU column.
4. Review the Memory column.
5. Review the Disk column.
6. Look for applications consuming unusually high resources.

You can click a column heading to sort processes by the corresponding measurement.

For example, if an application is consuming a large amount of CPU while you are not using it, investigate why.

Some resource-intensive tasks are normal. Windows Update, file indexing, antivirus scans, and software installations may temporarily use more system resources.

Give these tasks time to finish when appropriate.

Should You End Every High-Usage Process?

No.

Avoid ending unfamiliar system processes simply because they use CPU or memory.

Closing an application you recognize and no longer need is generally safer than terminating an essential Windows process.

If a process consistently consumes excessive resources, check the application's settings, update history, and official troubleshooting documentation.

10. Scan Your PC for Malware

Malware can cause unusual CPU usage, excessive disk activity, unwanted applications, and other performance problems.

If your computer suddenly becomes slower, displays unexpected advertisements, or launches unfamiliar programs, a security scan is a sensible step.

Windows includes Microsoft Defender Antivirus through Windows Security.

How to Run a Quick Malware Scan

1. Open Settings.
2. Select Privacy & security.
3. Choose Windows Security.
4. Open Virus & threat protection.
5. Select Quick scan.

Follow any instructions Windows displays.

A quick scan checks common locations for threats. If you suspect a persistent infection, consider a more comprehensive scan using the options available in Windows Security.

Keep your security software updated.

Avoid downloading supposed antivirus tools from suspicious advertisements or websites claiming that your computer has hundreds of problems.

Remember: A clean malware scan does not guarantee that every performance problem has been resolved. You may still need to investigate startup applications, storage, drivers, or hardware.

11. Optimize Your Storage Drive

Your storage device affects how quickly Windows starts, applications launch, and files load.

Traditional hard disk drives (HDDs) use moving mechanical components. Solid-state drives (SSDs) use flash memory and generally provide much faster access to data.

If your computer still uses an HDD as its primary system drive, upgrading to an SSD may produce a more noticeable improvement than many software adjustments.

Before considering an upgrade, determine which type of drive your PC currently uses.

How to Optimize a Drive in Windows 11

Windows includes a drive optimization utility.

1. Press the Windows key.
2. Search for Defragment and Optimize Drives.
3. Open the utility.
4. Select the drive you want to examine.
5. Review the media type and current status.
6. Select Optimize when appropriate.

Windows generally handles optimization differently for HDDs and SSDs.

Traditional hard drives may benefit from defragmentation, while SSD maintenance uses appropriate optimization methods such as retrim when supported.

You should not routinely force traditional HDD-style defragmentation on an SSD using unfamiliar third-party tools.

Let Windows manage normal drive optimization unless you have a specific reason to troubleshoot it manually.

When Should You Upgrade to an SSD?

Consider an SSD upgrade if:

• Your PC uses an HDD as its primary Windows drive.
• Windows takes a long time to start.
• Applications load slowly despite adequate memory.
• Disk activity frequently reaches very high levels during routine tasks.

Check your computer's specifications before buying an SSD. Not every computer supports every drive size or interface.

Also back up your important files before performing a hardware upgrade or reinstalling Windows.

12. Reduce Unnecessary Background Activity

Some applications can continue running in the background even when you are not actively using them.

Depending on the application, this may affect CPU usage, memory, network activity, or battery life.

Reducing unnecessary background activity can help on computers with limited resources.

How to Review Background Permissions

For supported applications:

1. Open Settings.
2. Select Apps.
3. Choose Installed apps.
4. Find the application you want to manage.
5. Open its three-dot menu.
6. Select Advanced options, if available.
7. Look for Background app permissions.
8. Change the setting if the option is supported.

Not every desktop application offers this setting.

You can also check individual applications for options that control automatic startup, background synchronization, and update behavior.

What Should Remain Active?

Do not disable background activity indiscriminately.

Some applications need to run in the background to provide notifications, synchronize files, manage security, or perform important tasks.

Focus on applications that you recognize and do not need running continuously.

13. Free Up Memory by Closing Unused Applications

Randomly closing applications is not always necessary, because Windows manages memory automatically.

However, if your PC has limited RAM and you run many demanding applications simultaneously, reducing the workload can improve responsiveness.

How to Check Memory Usage

1. Press Ctrl + Shift + Esc.
2. Open Task Manager.
3. Select the Performance section.
4. Choose Memory.
5. Review the amount of memory in use.

Return to the Processes tab to identify applications consuming large amounts of memory.

If you have several browser windows open, try closing tabs you no longer need.

You can also close unused editing applications, game launchers, virtual machines, or other demanding programs.

When Is More RAM Worth Considering?

A memory upgrade may help if your computer regularly runs out of available memory during your normal workload.

For example, someone who edits large photos while keeping multiple browser tabs and office applications open may benefit from additional RAM.

However, memory requirements vary by application.

Check your computer's specifications, upgrade limitations, and compatibility before purchasing additional memory.

14. Check Your Browser and Extensions

A slow computer is not always a Windows problem.

Sometimes, a web browser consumes excessive resources because of too many open tabs, demanding websites, or poorly behaving extensions.

If your computer becomes slow mainly when browsing the web, investigate the browser first.

Reduce Browser Resource Usage

Try these steps:

1. Close tabs you no longer need.
2. Remove extensions you do not recognize or use.
3. Update your browser.
4. Check the browser's built-in task manager, if available.
5. Compare performance with extensions temporarily disabled.
6. Restart the browser.

Some browsers include memory-saving features that can reduce the resources used by inactive tabs.

Review your browser's official documentation to learn which options are available.

Should You Install a PC Cleaner to Speed Up Your Browser?

Usually, you can start by using the browser's built-in tools.

Be cautious with applications that promise dramatic speed improvements through one-click cleaning.

Some unnecessary utilities consume resources themselves, while others may remove useful data or change settings you wanted to keep.

Start with simple, reversible changes before installing additional software.

15. Consider a Hardware Upgrade if Software Fixes Are Not Enough

If you have tried the previous methods and your PC remains slow, the hardware may be the limiting factor.

Software optimization can reduce unnecessary workload, but it cannot transform every older computer into a high-performance machine.

Before purchasing a new computer, consider whether a targeted hardware upgrade would be sufficient.

Upgrade to an SSD

If your system still runs from a traditional HDD, an SSD can substantially improve startup times and application loading.

Check your computer's compatibility before buying one.

Add More RAM

Additional memory may improve multitasking when your current RAM capacity is insufficient.

However, some laptops have soldered memory or other upgrade limitations.

Confirm whether your device supports a memory upgrade.

Improve Cooling

Excessive heat can cause some processors to reduce performance to protect themselves.

Make sure ventilation openings are not blocked and that the computer is used on a suitable surface.

If overheating persists, the cooling system may require professional inspection.

Consider a New Computer

If your processor, memory, storage, and other components cannot meet your current needs, replacing the computer may eventually be the most practical option.

Compare the cost of upgrades with the price of a suitable replacement before making a decision.

How to Make Windows 11 Faster for Gaming

If you mainly want better gaming performance, concentrate on the settings that affect games rather than applying every general-purpose optimization.

Start with these steps:

• Update your graphics driver through an appropriate official source.
• Close unnecessary applications while gaming.
• Make sure your computer meets the game's hardware requirements.
• Check that your game uses the intended graphics processor on systems with multiple GPUs.
• Review the game's resolution and graphics settings.
• Keep sufficient free storage available.
• Monitor CPU and GPU temperatures if performance drops during extended sessions.

If your laptop offers a performance mode, test it while connected to power.

However, increased performance settings may generate more heat and fan noise.

Avoid utilities that promise guaranteed FPS increases without explaining what they change.

For demanding games, the graphics card, processor, memory capacity, cooling, and game optimization can matter more than minor Windows interface adjustments.

How to Make an Old Windows 11 PC Faster

Older computers may require a different approach from newer systems.

If you are using an older PC, begin with the most practical steps:

1. Disable unnecessary startup applications.
2. Remove applications you no longer use.
3. Free up disk space.
4. Check Task Manager for unusually high resource usage.
5. Install appropriate Windows and driver updates.
6. Run a malware scan.
7. Reduce visual effects if necessary.
8. Check whether the computer uses an HDD or SSD.
9. Review available memory.
10. Confirm that the hardware meets the requirements of your applications.

Do not expect every older computer to become dramatically faster through software adjustments alone.

If the computer has limited memory and a mechanical hard drive, an SSD or RAM upgrade may provide more meaningful benefits, provided the hardware supports those upgrades.

Windows 11 Optimization Mistakes You Should Avoid

Some popular speed-up tips can create problems instead of solving them.

Keep the following precautions in mind.

Do Not Disable Random Windows Services

Windows services support important operating system functions.

Disabling unfamiliar services can break features, interfere with updates, or create stability problems.

Avoid online optimization guides that tell you to turn off large numbers of services without explaining the consequences.

Do Not Delete System Files Manually

Removing unfamiliar files from Windows system folders can make applications or the operating system stop working correctly.

Use Windows cleanup tools and uninstallers whenever possible.

Avoid Registry Tweaks You Do Not Understand

The Windows Registry contains configuration information used by Windows and applications.

Incorrect changes can cause unexpected behavior.

Before applying a registry modification, make sure you understand its purpose, potential side effects, and recovery method.

Most users should begin with ordinary Windows settings rather than advanced registry changes.

Do Not Trust Every PC Cleaner Advertisement

Be skeptical of programs that claim to fix hundreds of errors or make every computer dramatically faster.

Use reputable software from official sources, and review what a program will change before allowing it to make system modifications.

Do Not Expect One Setting to Fix Everything

Slow performance can have multiple causes.

A computer with a nearly full drive may benefit from cleanup, while another with insufficient RAM may need a hardware upgrade.

Diagnosing the actual problem is more useful than applying every available optimization indiscriminately.
