⚡ Before You Start
Before changing Windows settings, it is a good idea to identify what is actually causing the slowdown.
Press:
This opens Task Manager.
Click the Performance tab and check your CPU, Memory, Disk, and GPU usage.
If your memory is constantly near 90–100%, you may need to reduce the number of applications running at the same time or consider a RAM upgrade.
If your Disk usage remains at 100%, investigate which applications or services are causing the activity before making major changes.
1️⃣ Disable Unnecessary Startup Apps
One of the easiest ways to make a low-end Windows 11 PC start faster is to reduce the number of applications that automatically launch when Windows starts.
Many applications configure themselves to run automatically in the background. On a computer with limited hardware, too many startup programs can increase boot time and consume RAM and CPU resources.
How to Disable Startup Apps
- Right-click the Start button.
- Open Task Manager.
- Click Startup apps.
- Review the applications listed.
- Right-click unnecessary applications.
- Select Disable.
Do not randomly disable Windows system components or security software. Focus on applications you recognize and don't need to launch automatically.
2️⃣ Reduce Windows Visual Effects
Windows 11 includes animations, transparency, shadows, and other visual effects that make the operating system look modern.
However, on a low-end computer, reducing some of these effects can make Windows feel more responsive.
How to Adjust Visual Effects
- Press Windows + R.
- Type sysdm.cpl.
- Press Enter.
- Open the Advanced tab.
- Under Performance, click Settings.
- Select Adjust for best performance.
- Click Apply.
You can also manually select the visual effects you want to keep if you don't want to completely disable them.
3️⃣ Disable Unnecessary Background Apps
Some applications continue running in the background even when you're not actively using them.
On a low-end PC, unnecessary background activity can consume valuable RAM, CPU resources, and battery power.
What You Can Do
Open:
Review applications you rarely use and remove unnecessary software.
For applications that provide background permissions, review their settings and restrict background activity where appropriate.
4️⃣ Free Up Storage Space
A nearly full system drive can make it harder for Windows and applications to operate efficiently.
Removing unnecessary files can free valuable storage space and make it easier to manage your system.
Use Windows Storage Settings
- Open Settings.
- Go to System.
- Select Storage.
- Review the categories using the most storage.
- Remove unnecessary temporary files.
You can also enable Storage Sense to automatically manage certain temporary files and free up space.
Try to keep a reasonable amount of free space available on your Windows system drive instead of allowing it to become completely full.
5️⃣ Uninstall Programs You Don't Need
Low-end PCs often become slower over time because users install many applications, utilities, launchers, and background services.
If you haven't used a program for months, consider uninstalling it.
How to Uninstall Apps
- Open Settings.
- Select Apps.
- Open Installed apps.
- Find software you no longer need.
- Click the three-dot menu.
- Select Uninstall.
Removing unnecessary software can also reduce background processes and free storage space.
6️⃣ Choose a Performance-Friendly Power Mode
Windows 11 provides power modes that control how the system balances performance and energy consumption.
If your computer is connected to power and you need maximum responsiveness, selecting a performance-oriented power mode may help, depending on the hardware.
How to Change Power Mode
- Open Settings.
- Go to System.
- Select Power & battery.
- Find Power mode.
- Select the performance-oriented option available on your system.
Higher performance settings can increase power consumption and heat, especially on laptops.
7️⃣ Optimize Your Web Browser
For many people, the web browser is one of the applications they use most.
If you have many browser tabs, extensions, and applications running simultaneously, your low-end PC can quickly run out of available RAM.
Try These Browser Optimization Tips
- Close tabs you aren't using.
- Remove unnecessary browser extensions.
- Keep your browser updated.
- Avoid running multiple browsers at the same time.
- Restart the browser when memory usage becomes excessive.
If your PC has only 4GB of RAM, limiting the number of simultaneously open applications can make a noticeable difference.
8️⃣ Keep Windows and Drivers Updated
Windows updates can include security improvements, bug fixes, compatibility improvements, and performance-related changes.
You should therefore avoid permanently disabling Windows Update just because your computer is slow.
Check for Windows Updates
Also make sure important device drivers are properly installed and maintained, particularly graphics, chipset, network, and storage-related drivers where applicable.
Avoid downloading random driver packages from unknown websites. Prefer Windows Update or the official hardware manufacturer's support page.
9️⃣ Clean Up Temporary Files
Windows and installed applications create temporary files during normal operation.
Removing unnecessary temporary files can recover storage space and keep your system organized.
Use Windows Temporary File Cleanup
- Open Settings.
- Go to System.
- Click Storage.
- Select Temporary files.
- Review the files carefully.
- Remove files you no longer need.
Be careful when selecting files to delete. Review the categories before confirming the cleanup.
🔟 Upgrade Your Hardware If Possible
Software optimization can help, but there is a limit to how much you can improve an older computer through settings alone.
If your low-end PC still struggles after optimization, a hardware upgrade may provide the biggest improvement.
Best Upgrades for an Older PC
- Upgrade from an HDD to an SSD if your computer still uses a mechanical hard drive.
- Increase RAM if your system supports it.
- Use a faster SSD when your existing storage is slow or failing.
- Clean dust from the cooling system if overheating is causing performance problems.
For many older computers still using a traditional hard drive, moving Windows to a compatible SSD can produce a much larger improvement in everyday responsiveness than changing a few Windows visual settings.
🎁 Bonus Tips for Low-End Windows 11 PCs
