Why does Windows 11 lose performance?
The most common causes are:
Too many programs launching with Windows.
Low free disk space.
Accumulated temporary files.
Outdated drivers.
Mechanical hard drive (HDD).
Malware or unwanted software.
Pending updates.
Before making advanced changes, Microsoft recommends running built-in maintenance tools and ensuring Windows is up to date.
1. Disable programs that start with Windows
One of the most common mistakes is allowing too many applications to run when the system starts up.
How to do it:
Press Ctrl + Shift + Esc.
Open Task Manager.
Go to Startup apps.
Disable non-essential programs. 💡 TechDano Tip
Do not disable Windows Security, video drivers, or manufacturer software if you are unsure of their function.
2. Free up disk space:
Windows needs free space to function correctly.
Ideally, maintain:
At least 20 GB.
50 GB or more for better performance.
Go to:
Settings → System → Storage
From there, you can identify what is taking up the most space.
3. Delete temporary files:
Over time, Windows accumulates files that are no longer needed.
Do the following:
Press Windows + R.
Type:
%temp%
Delete the temporary files.
Then repeat the process by typing:
temp
and then:
prefetch
⚠️ Some files will be in use and cannot be deleted. This is completely normal.
4. Enable Storage Sense:
Windows 11 includes a tool that automatically deletes temporary files and empties the Recycle Bin.
To enable it:
Settings.
System.
Storage.
Storage Sense.
Turn on.
This feature helps maintain available space without manual intervention.
5. Reduce visual effects
Animations make Windows look modern, but they consume resources.
To improve performance:
Search for "View advanced system settings".
Click Settings under Performance.
Select:
Adjust for best performance.
If you prefer to keep a pleasing appearance, you can re-enable only the animations you like best.
6. Keep Windows updated:
Updates don't just add new features; they also fix bugs and improve performance.
Go to:
Settings → Windows Update → Check for updates
If you encounter errors during the update, run the troubleshooter and, if necessary, use the DISM and SFC tools to repair system files.
7. Update drivers:
Outdated drivers can cause poor performance or instability.
Specifically, update:
Graphics card.
Chipset.
Wi-Fi.
Bluetooth.
Audio. Always download them from the equipment or component manufacturer.
8. Check the disk status:
If you suspect the disk has errors:
Open Command Prompt as administrator and run:
chkdsk /f C:
The system may ask you to restart the computer to complete the check.
9. Uninstall programs you don't use:
Many computers come with pre-installed software that consumes memory and resources.
To remove it:
Settings.
Apps.
Installed apps.
Uninstall the ones you no longer use.
Before removing a program, verify that it is not necessary for the computer's operation.
10. Is it worth switching to an SSD?:
If you are still using a mechanical hard drive (HDD), switching to an SSD is usually the most noticeable upgrade.
HDD SSD
Slow startup Startup in seconds
Noisier Silent
MoSusceptible to impact damage More durable
Slower speeds Much faster
💡 TechDano Tip: If you are on a tight budget, prioritize installing an SSD over upgrading other components, especially on older computers.
Mistakes to avoid:
❌ Installing "miracle" optimization tools.
❌ Disabling Windows services without knowing what they do.
❌ Downloading programs from unofficial sites.
❌ Cleaning the registry with unknown tools.
These changes often cause more problems than they solve.
Frequently Asked Questions
Does Windows 11 require more RAM?
A minimum of 8 GB of RAM is recommended for smooth performance. If you work with video editing, virtual machines, or modern games, 16 GB offers a better experience.
Should I defragment an SSD?
No. Windows automatically detects SSDs and uses appropriate optimization tasks, which differ from traditional defragmentation.
How much free space should I leave?
It is recommended to keep at least 15–20% of the disk free to ensure Windows runs correctly.
Is it advisable to install programs to speed up Windows?
In most cases, no. Windows' built-in tools are sufficient for basic maintenance and help avoid the risks associated with unnecessary software.
Conclusion:
Improving Windows 11 performance does not require advanced technical knowledge or third-party software. Through periodic maintenance—removing unnecessary applications, keeping the system updated, and using built-in Windows tools—it is possible to restore much of the computer's original performance.
If the computer remains very slow after applying these tips, the next recommended step is to check the hardware status, specifically the storage drive and RAM.
