Introduction
The slowness of a windows PC is very aggravating- particularly when the basic processes such as opening an application, internet usage, and even the process of booting the computer end up taking ages. Performance problems are not relevant only to experts, a programmer, or an average user.
The good news?
There is no need to purchase a new computer.
You will know the way to repair your slow Windows PC with the help of the practical and proven steps in this guide, starting with the simple methods of repairing your computer, and finishing with the advanced methods of optimizing the performance of your computer. These are applicable to Windows 10 and Windows 11.
1. Restart Your PC (Yes, It Matters)
The easiest solution is ignored by a great number of users.
When your PC is being used over long periods of time:
• Background processes get piling up
• Memory gets clogged
• System resources are wasted
Solution:
Reboot your computer at least after every few days.
Developers may run systems weeks long- this by itself can bring slowdowns.
2. Disable Startup Programs
There are several programs that begin with windows and can incredibly reduce the speed of booting and the performance in general.
How to Disable Startup Apps:
- Press Ctrl + Shift + Esc (Task Manager)
- Click Startup
- Disable unnecessary apps (right-click → Disable)
Avoid Disabling:
• Antivirus software
• System drivers
3. Uninstall Software that is Not Necessary.
Unused software consumes:
• Disk space
• RAM
• Background CPU resources
Steps:
- Open Control Panel
- Click Programs & Features
- Uninstall any software which you are not using.
Uninstall trial programs and bloatware installed on the machine.
4. Malware and Viruses Check.
One of the leading reasons of slow windows PCs is malware.
What to Do:
• Windows Defender (inbuilt) should be used.
• Run a Full Scan
• Optionally install such tools as Malwarebytes.
Warning:
Do not download pirated versions of software- it is a performance killer.
5. Free Up Disk Space
Windows slows down when your system drive (C:) has almost been filled up.
Disk Cleanup Steps:
- Open This PC
- Right-click Local Disk (C:)
- Click on Properties Select Cleanup Disk.
- Scanning system cache and checking temporary files.
It is best to maintain at least 20–25% of free space in the main drive.
6. Upgrade to SSD (Best Performance Increase).
And this is your largest bottleneck in case you still have an HDD in use.
Benefits of SSD:
• Faster boot times
• Quick app loading
• Smooth multitasking
The PC of a 5-year-old can be made to feel new even with a low-end SSD.
7. Enhance RAM to Multitask Improved.
Low RAM causes:
• Freezing
• App crashes
• Slow response
Recommended RAM:
• 8GB – Minimum (General users)
• 16GB+ – Multitaskers & developers.
Task Manager Performance Memory Check RAM.
8. Setting Visual Effects to Better Performance.
Windows animations are beautiful–but expensive.
Steps:
- Search Performance
- Open customize the Windows looks and functionality.
- Choice Adjust to optimum performance.
- Apply changes
Output:
Improved response time and slowed down the lag.
9. Update Windows and Drivers
Outdated software causes:
• Bugs
• Performance issues
• Security risks
Update Steps:
• Settings → Windows Update → Check for updates
• Update Graphic drivers (Intel / NVIDIA / AMD) update.
Optimized driver updates are beneficial to developers.
10. Check Background Processes
There are apps that run silently but consume the resources.
How:
- Open Task Manager
- Sort by CPU / Memory
- Determine app resource-consumers.
- End unnecessary tasks
It is advisable not to murder system processes without any certainty.
11. Enable Storage Sense
Storage Sense auto junk cleaning.
Steps:
- Settings → System → Storage
- Turn Storage Sense ON
This maintains your system and does not have to work on it manually.
12. Reset or Reinstall Windows (Final Solution)
When all else fails, a clean install of Windows will restore it.
Options:
• Reset this PC (Keep files)
• Clean Windows installation
Make a copy of vital information and then move on.
Bonus Tips for Developers
• Infringe unwanted services.
• Use lightweight IDEs where there is the possibility.
• Docker / VMs should only be used on demand.
• Observation of system with Process Explorer.
