Have you noticed that your Windows 11 PC is using too much RAM even when you are not running many programs?
High RAM usage can make your computer feel slow, cause applications to freeze, and reduce gaming performance.
Common symptoms include:
- Slow PC performance
- Programs opening slowly
- Browser freezing
- Games having stutters
- Windows becoming unresponsive
- High memory usage in Task Manager
In this guide, I will share the best methods to reduce high RAM usage in Windows 11 and improve your PC performance.
What Causes High RAM Usage in Windows 11?
RAM (Random Access Memory) is used by Windows and applications to store temporary data for faster performance.
High RAM usage can happen because of:
- Too many background applications
- Too many startup programs
- Browser extensions
- Windows services
- Malware or unwanted software
- Memory leaks
- Low physical RAM capacity
- Heavy applications and games
Method 1: Check Which Apps Are Using RAM
Before changing settings, find the reason.
Steps:
- Press:
Ctrl + Shift + Esc
- Open:
Task Manager
- Click:
Processes
- Select:
Memory
Check which programs are using the most RAM.
Close applications you do not need.
Method 2: Disable Unnecessary Startup Programs
Many programs automatically start with Windows and consume memory.
Steps:
- Open:
Task Manager
- Go to:
Startup Apps
- Disable unnecessary programs
Examples:
- Game launchers
- Update assistants
- Unused software
- Background utilities
Keep important programs like:
- Antivirus
- Graphics drivers
- Hardware control software
Method 3: Restart Your PC Regularly
Sometimes Windows applications do not fully release memory after running for a long time.
A restart clears:
- Temporary memory usage
- Background processes
- Stuck applications
Restarting your PC can often solve temporary RAM problems.
Method 4: Reduce Browser RAM Usage
Web browsers can use a large amount of memory.
Try:
- Closing unused tabs
- Removing unnecessary extensions
- Enabling memory saver mode
- Restarting your browser regularly
Browsers with many tabs can consume several GB of RAM.
Method 5: Disable Background Apps
Some applications continue running even when you are not using them.
Steps:
- Open:
Settings
- Go to:
Apps → Installed Apps
- Remove unnecessary applications
Also check applications running in the background.
Method 6: Adjust Windows Visual Effects
Windows animations use system resources.
Steps:
- Search:
Adjust the appearance and performance of Windows
- Select:
Adjust for best performance
- Apply changes
This can help older PCs with limited RAM.
Method 7: Scan for Malware
Some unwanted programs secretly run in the background and consume RAM.
Run:
Windows Security → Virus & Threat Protection → Full Scan
Remove any detected threats.
Method 8: Update Windows and Drivers
Outdated software can cause memory problems.
Update:
- Windows 11
- Graphics drivers
- Chipset drivers
- Network drivers
Driver updates can fix:
- Memory leaks
- System instability
- Performance problems
Method 9: Disable Unnecessary Windows Services
Some Windows services are not required for every user.
Open:
Windows Key + R
Type:
services.mscDisable only services you understand.
Incorrect changes can affect Windows functionality.
Method 10: Increase Virtual Memory
Virtual memory uses storage space as additional memory when RAM becomes full.
Steps:
- Search:
Advanced System Settings
- Open:
Performance Options
- Select:
Advanced → Virtual Memory
- Adjust settings if required
For most users, letting Windows manage virtual memory is recommended.
Method 11: Check If You Need More RAM
Sometimes the problem is not Windows settings.
Modern usage requires more RAM:
- Basic use: 8GB
- Gaming: 16GB minimum
- Heavy gaming/content creation: 32GB+
If your RAM is always near maximum usage, upgrading may be the best solution.
