All computers get slower over time. Programs that install in the background, accumulated temporary files, and visual effects that consume resources make a machine that once worked well now take minutes to boot up.
The good news is that most of these problems can be solved without formatting, buying new hardware, or paying for optimization software. These 15 tricks work on both Windows 10 and Windows 11.
1. Disable unnecessary startup programs
Press Ctrl + Shift + Esc to open Task Manager. Go to the "Startup" tab. You'll see a list of programs that open automatically when you turn on your computer.
Right-click on the ones you don't need immediately (like Spotify, Discord, Adobe Creative Cloud) and select "Disable". Keep only your antivirus and essential drivers active.
2. Clean temporary files
Press Win + R, type %temp%, and press Enter. A folder full of temporary files opens. Select all (Ctrl + A) and delete them. Some won't delete because they're in use; leave those.
Repeat the process by typing temp in the Run dialog (without the percent signs).
3. Use Disk Cleanup
Search for "Disk Cleanup" in the Start menu. Select drive C: and check:
- Temporary Internet Files
- Recycle Bin
- Temporary files
- Thumbnails
Click "OK". You can recover several gigabytes.
4. Disable visual effects
Search for "View advanced system settings" and in the "Performance" tab click "Settings". Select "Adjust for best performance". Windows will look less fancy, but your computer will respond much faster.
5. Disable transparency and animations
Go to Settings > Accessibility > Visual effects. Turn off "Transparency effects" and "Animation effects". Especially on computers with integrated graphics, this frees up valuable resources.
6. Uninstall programs you don't use
Go to Settings > Apps > Installed apps. Sort by size and uninstall everything you don't use. Many laptop manufacturers install trial software (bloatware) that only consumes space and RAM.
7. Disable search indexing
Right-click on drive C:, select Properties, and uncheck "Allow files on this drive to have contents indexed". File searches will be slightly slower, but the system overall will gain performance.
8. Check for malware
Run a full scan with Windows Defender or your preferred antivirus. Malware consumes resources in the background without you noticing.
9. Update drivers
Outdated drivers, especially graphics and hard drive drivers, can cause slowness. Go to Settings > Windows Update > Advanced options > Optional updates and check if there are pending drivers.
10. Change the power plan
Search for "Power Options" in Control Panel. Select "High performance" if you're plugged in. On laptops, this consumes more battery but improves immediate system response.
11. Disable unnecessary notifications
Go to Settings > System > Notifications. Turn off notifications from apps you don't need. Every notification consumes system resources.
12. Clean the registry with caution
Don't use automatic registry cleaners. Instead, uninstall programs correctly from Settings > Apps. A clean registry comes from good habits, not aggressive tools.
13. Check your hard drive status
If you use a mechanical hard drive (HDD) instead of SSD, fragmentation slows everything down. Search for "Defragment and Optimize Drives". If you have an SSD, don't defragment it; Windows will automatically optimize it with TRIM.
14. Increase virtual memory
Search for "View advanced system settings" > Performance > Advanced > Virtual memory. If you have little RAM (4 GB or less), increase the paging file size to 1.5 times your physical RAM.
15. Restart your computer at least once a week
Windows accumulates processes and memory leaks over time. A weekly restart completely clears this.
When optimization isn't enough anymore
If after applying all these tricks your computer is still too slow to work or study, it probably has very old hardware or damaged components. In that case, the best option is to donate it to Crezendo. We accept computers in any condition. Equipment that can't be repaired is used to teach hardware diagnostics and repair. A 10-year-old laptop is perfect study material for someone who has never opened a computer.
If for some reason you cannot donate it, you might consider using it for very basic tasks like a home server, while looking for a functional device.
If you have an old laptop you no longer use, donating it to an educational foundation is one of the best decisions you can make. At Crezendo, we give it a second life as a learning tool for people who otherwise would never have access to a computer.
