Windows 11 Problems? 9 Easy Ways to Make Your Old PC
Faster in 2026
Is your old PC running slowly after upgrading to Windows 11?
You are not alone. Many Australians continue using older desktops and laptops
for work, study, streaming, browsing, and everyday tasks. Over time, however,
Windows 11 can start feeling sluggish, especially when your computer has
limited RAM, an older processor, or a traditional hard disk drive (HDD).
The good news is that you do not always need to buy a new
computer. With a few simple Windows 11 performance tweaks, you can often make
an old PC noticeably faster and more responsive.
In this guide, we will explain 9 easy ways to speed up a
Windows 11 PC in 2026, including practical solutions that do not require
advanced technical knowledge.
Why Is Your Windows 11 PC So Slow?
Before changing anything, it helps to understand what may be
causing the slowdown.
An older Windows 11 computer can become slow because of too
many startup programs, insufficient storage space, background applications,
outdated drivers, excessive temporary files, or an ageing HDD.
If your PC has been used for several years, Windows may also
be competing for limited hardware resources. A computer that was fast when new
may struggle with modern websites, applications, video calls, and multitasking.
Instead of immediately replacing the computer, try the
following solutions.
1. Disable Unnecessary Startup Apps
One of the easiest ways to make Windows 11 boot faster is to
reduce the number of programs that automatically start with Windows.
Some applications launch every time you turn on your
computer even though you may only use them occasionally. These programs consume
RAM and CPU resources in the background.
How to disable startup apps:
- Press
Ctrl + Shift + Esc to open Task Manager.
- Select
Startup apps.
- Look
at the programs listed.
- Right-click
applications you do not need at startup.
- Select
Disable.
Avoid disabling essential Windows components or security
software if you are unsure what they do.
Reducing unnecessary startup applications can make an older
PC feel faster immediately after logging in.
2. Free Up Storage Space
A nearly full drive can contribute to poor PC performance.
Windows needs available storage for temporary files, updates, caching, and
other system operations.
Check your available space by going to:
Settings → System → Storage
Windows 11 provides storage management tools that can help
identify large files and unnecessary data.
Remove temporary files, old downloads, unused applications,
and other files you no longer need.
For Australian users with limited internet plans or older
hardware, this is also a useful opportunity to remove applications and files
that are consuming resources unnecessarily.
Quick tip
Try to avoid letting your system drive become completely
full. Keeping a reasonable amount of free space can help Windows operate more
comfortably.
3. Uninstall Programs You Never Use
Old PCs often contain years of unused applications.
You may have installed software for a particular project,
game, printer, school assignment, or work task and never removed it.
Go to:
Settings → Apps → Installed apps
Review the applications and uninstall programs you no longer
need.
This does more than recover storage. Some applications
install background services that continue running even when you are not
actively using them.
Removing unnecessary software can therefore reduce
background activity and improve overall responsiveness.
4. Upgrade from an HDD to an SSD
If your old computer still uses a traditional mechanical
hard drive, upgrading to an SSD can be one of the biggest performance
improvements available.
An SSD has no moving mechanical parts and generally provides
much faster access to files than a traditional HDD.
You may notice improvements when:
- Starting
Windows 11
- Opening
applications
- Searching
for files
- Loading
documents
- Copying
data
- Restarting
the computer
For many older desktop PCs and laptops, an SSD upgrade can
make the computer feel dramatically newer without replacing the entire system.
Before purchasing an SSD, check whether your computer
supports the required drive type and connection. Some older systems use SATA
drives, while newer devices may support M.2 NVMe storage.
5. Increase Your RAM
RAM plays an important role when you are multitasking.
If your old PC frequently becomes slow when you have
multiple browser tabs, Microsoft Office applications, video calls, and other
programs open simultaneously, limited RAM could be part of the problem.
Open Task Manager → Performance → Memory and monitor
your RAM usage while performing normal tasks.
If memory usage is consistently very high, upgrading the RAM
may help.
The exact upgrade depends on your computer's motherboard or
laptop specifications. Some older laptops have upgradeable memory, while others
have RAM permanently attached to the motherboard.
Before buying memory, check the maximum supported RAM and
the correct memory type for your specific PC.
6. Reduce Unnecessary Background Apps
Windows 11 can run many applications and services in the
background.
Although background activity can be useful, unnecessary
applications can consume CPU, memory, battery power, and network resources.
Review which applications are allowed to run in the
background and close programs you are not using.
You can also check Task Manager to identify applications
consuming unusually high amounts of CPU, memory, disk, or network resources.
If a particular application constantly consumes significant
resources, investigate whether it needs to run continuously.
Do not randomly terminate Windows system processes. If you
do not recognise a process, research it before disabling or removing anything.
7. Keep Windows and Drivers Updated
Keeping Windows 11 updated can help maintain system
stability, compatibility, and security.
Go to:
Settings → Windows Update
and check for available updates.
You should also keep important hardware drivers updated,
particularly graphics, chipset, storage, and network drivers.
However, avoid downloading random driver packages from
unfamiliar websites. Use Windows Update or the official website of your PC,
motherboard, or hardware manufacturer whenever possible.
Updates are particularly important if your computer has
recently developed crashes, compatibility problems, or unusual performance
issues.
8. Adjust Windows 11 Visual Effects
Windows 11 includes modern animations, transparency effects,
and other visual features designed to make the interface look polished.
On powerful modern computers, these effects are usually not
a problem. On an older PC with limited hardware, reducing visual effects may
make the system feel more responsive.
Search Windows for:
“Adjust the appearance and performance of Windows”
From the Performance Options menu, you can select settings
that prioritise performance.
You do not necessarily need to disable every visual effect.
Experiment with the settings and keep the features you like while reducing
unnecessary animations.
This is especially useful on older laptops with limited
graphics performance.
9. Clean Your PC and Check for Overheating
Hardware problems can sometimes look like software problems.
Dust buildup inside a desktop or laptop can restrict airflow
and cause components to run hotter. When temperatures become too high,
processors may reduce their speed to protect the hardware.
Signs of overheating can include:
- Loud
fans
- Sudden
performance drops
- Random
shutdowns
- Slow
performance after extended use
- Excessive
heat around the computer
Keep air vents unobstructed and clean dust carefully
according to the manufacturer's recommendations.
For laptops, avoid using them on soft surfaces such as beds
or thick blankets because these can restrict ventilation.
If you are uncomfortable opening a laptop or desktop,
consider having a qualified technician inspect and clean it.
Should You Buy a New PC Instead?
Sometimes an old computer simply cannot keep up with modern
software.
If your PC has an old processor, very little RAM, a failing
hard drive, and limited upgrade options, spending money on multiple upgrades
may not make financial sense.
However, if the main problem is an HDD, insufficient RAM, or
unnecessary software, a relatively inexpensive upgrade may extend the useful
life of the computer.
Before replacing an older PC, consider whether an SSD
upgrade or RAM upgrade could solve the problem.
This approach can also reduce electronic waste. Australia's
Department of Climate Change, Energy, the Environment and Water reports that
Australia generated approximately 511,000 tonnes of e-waste in 2019,
with e-waste expected to increase substantially by 2030.
What Should You Upgrade First?
If you want the biggest improvement for an older Windows 11
PC, consider this order:
1. Check for malware and unnecessary software
2. Disable unnecessary startup programs
3. Free up storage space
4. Upgrade an HDD to an SSD
5. Upgrade RAM if your system supports it
6. Check temperatures and airflow
7. Keep Windows and drivers updated
You do not necessarily need to perform every upgrade. Start
with the simplest solutions and test your computer after each change.
When It Is Time to Replace Your Old PC
If your computer remains extremely slow after cleaning up
Windows, upgrading storage, and improving RAM, the underlying hardware may
simply be too old.
Other warning signs include frequent crashes, hardware
failures, an unsupported processor, a damaged display, battery problems, or a
drive that is showing signs of failure.
Before replacing the machine, back up your important
documents, photos, videos, and other personal data.
And don't simply throw the old computer in the household
rubbish bin.
In Australia, the National Television and Computer
Recycling Scheme (NTCRS) provides households and small businesses with
access to free, industry-funded recycling services for eligible televisions,
computers, printers, parts, and peripherals.
Collection services may be available through councils,
retailers, resource recovery centres, or other designated locations.
Final Thoughts
A slow Windows 11 PC does not automatically mean you need to
spend thousands of dollars on a new computer.
Simple changes such as disabling startup applications,
removing unused software, freeing storage, reducing visual effects, and keeping
Windows updated can improve everyday performance. For older hardware, upgrading
from an HDD to an SSD or adding compatible RAM can provide an even bigger
improvement.
The best strategy is to identify the actual bottleneck
before spending money.
If your PC is still suitable for your everyday needs, a few
carefully chosen upgrades could give it several more useful years.
