How To Reduce The RAM Usage In Windows 10

By Marlo Strydom

Your Windows 10 computer is running at 90% RAM usage with only a few programs open. Chrome is consuming 2GB, Windows background processes are eating another 1.5GB, and your system feels sluggish. Sound familiar? High RAM usage plagues millions of Windows 10 users, but you can reclaim 30-50% of your memory with the right optimization techniques.

Quick Solution: Most Windows 10 systems can reduce RAM usage by 1-3GB by disabling startup programs, adjusting virtual memory settings, and removing unnecessary background processes. Target RAM usage should stay between 40-70% for optimal performance.

Identify High RAM Usage with Task Manager

Task Manager provides real-time RAM usage monitoring and process identification. Understanding which programs consume your memory helps prioritize optimization efforts.

Accessing Advanced RAM Monitoring

  1. Press Ctrl + Shift + Esc to open Task Manager quickly
  2. Click "More details" if you see the simplified view
  3. Navigate to the "Processes" tab
  4. Click the "Memory" column header to sort by RAM usage
  5. Click "Memory" again to show highest usage first

Memory Usage Benchmarks: Web browsers typically use 500MB-2GB, Windows Explorer consumes 50-150MB, and background Windows processes should total under 2GB on 8GB systems.

Look for processes using more than 500MB of RAM. Common memory hogs include web browsers with multiple tabs, media editing software, and poorly optimized applications that run continuously in the background.

Disable Startup Programs

Startup programs launch automatically when Windows boots, consuming RAM even if you're not using them. Disabling unnecessary startup items can free 500MB to 2GB of memory immediately.

Optimizing Startup Impact

  1. Open Task Manager and select the "Startup" tab
  2. Review the "Startup impact" column showing High, Medium, or Low ratings
  3. Right-click programs with "High" impact you don't need immediately
  4. Select "Disable" to prevent automatic startup
  5. Focus on programs like Skype, Steam, Adobe updaters, and office suites

Warning: Never disable Windows Security, audio drivers, or essential hardware management software. Disabling the wrong startup programs can cause system instability or hardware malfunctions.

High-Impact Startup Programs to Consider Disabling

  • Steam Client: Typically uses 100-200MB and can be launched manually
  • Spotify/iTunes: Media players consume 150-300MB at startup
  • Adobe Updaters: Multiple Adobe processes can use 200-500MB combined
  • Office Programs: Microsoft Office startup items use 100-400MB
  • Gaming Software: Origin, Epic Games, Blizzard launchers use 100-250MB each

Remove Unnecessary Applications and Bloatware

Unused applications often run background services that consume RAM even when you're not actively using them. Windows 10 comes with pre-installed apps that many users never need.

Identifying Resource-Heavy Applications

  1. Open Settings (Windows key + I)
  2. Navigate to "Apps" > "Apps & features"
  3. Click "Sort by" and select "Size" to see largest programs first
  4. Click each large application to see its "Advanced options"
  5. Select "Uninstall" for programs you don't use

Common Windows 10 Bloatware to Remove

  • Xbox Game Bar: Consumes 50-100MB if you don't game

  • Windows Maps: Takes 100MB+ and rarely used on desktop PCs
  • 3D Viewer/Paint 3D: Combined 200MB+ for specialized 3D tasks
  • Skype (pre-installed): Auto-starts and uses 80-150MB

Adjust Virtual Memory Settings

Virtual memory uses hard drive space as supplemental RAM when physical memory fills up. Proper configuration reduces reliance on slower virtual memory and optimizes actual RAM usage patterns.

Calculating Optimal Virtual Memory Size

Virtual Memory Formula: Initial size = 1.5 × physical RAM, Maximum size = 3 × physical RAM. For 8GB systems: Initial = 12GB, Maximum = 24GB. For 16GB systems: Initial = 24GB, Maximum = 48GB.

  1. Right-click "This PC" and select "Properties"
  2. Click "Advanced system settings" on the left sidebar
  3. Under Performance, click "Settings"
  4. Select the "Advanced" tab in Performance Options
  5. Click "Change" under Virtual memory
  6. Uncheck "Automatically manage paging file size"
  7. Select "Custom size" and enter your calculated values
  8. Click "Set" then "OK" and restart your computer

Place the page file on your fastest drive (preferably an SSD) for better performance. If you have multiple drives, avoid placing the page file on the same drive as Windows to prevent bottlenecks.

Optimize Windows 10 for Best Performance

Windows 10's visual effects consume significant RAM through desktop composition, animations, and transparency effects. Adjusting these settings can free 200-800MB of memory.

Disabling Memory-Intensive Visual Effects

  1. Open Control Panel > System and Security > System
  2. Click "Advanced system settings"
  3. Under Performance, click "Settings"
  4. Select "Adjust for best performance" for maximum RAM savings
  5. Or choose "Custom" to disable specific effects while keeping others

Recommended Custom Visual Effects Settings

  • Keep Enabled: "Show thumbnails instead of icons" for file management
  • Keep Enabled: "Smooth edges of screen fonts" for text readability
  • Disable: "Animate windows when minimizing and maximizing" (saves 50-100MB)
  • Disable: "Fade or slide menus into view" (saves 30-70MB)
  • Disable: "Use drop shadows for icon labels on desktop" (saves 20-50MB)

Disable Background Apps

Windows 10 allows apps to run in the background even when closed, consuming RAM for notifications, updates, and data syncing. Controlling background app activity can recover 300-600MB of memory.

  1. Open Settings > Privacy
  2. Select "Background apps" from the left menu
  3. Toggle off "Let apps run in the background" for global disable
  4. Or individually disable specific apps that consume excessive memory

High-Impact Background Apps to Disable

  3. Identify motherboard compatibility: Use tools like CPU-Z or check manufacturer specs
  4. Verify maximum supported capacity and memory type (DDR4, DDR5)
  5. Purchase matching speed and timing specifications for existing modules

RAM Upgrade Impact: Upgrading from 8GB to 16GB typically reduces virtual memory usage by 60-80%, eliminates memory-related slowdowns, and allows for better multitasking with memory-intensive applications. Use our RAM Configuration Optimizer to determine the ideal RAM amount and configuration for your specific needs.

Monitor Long-term RAM Performance

Regular monitoring helps maintain optimal RAM usage and identify memory leaks or degrading performance before they become problematic.

Setting Up Performance Monitoring

  • Resource Monitor: Press Windows key + R, type "resmon" for detailed memory analysis
  • Performance Counter: Monitor "Available MBytes" and "Pages/sec" in perfmon.exe
  • Third-party Tools: Consider HWiNFO64 or Process Explorer for advanced monitoring
  • Regular Maintenance: Check RAM usage weekly and restart when memory usage exceeds 85%

Optimizing RAM Usage for Peak Performance

Reducing Windows 10 RAM usage requires a systematic approach combining immediate fixes with long-term optimization strategies. Start with high-impact changes like disabling startup programs and removing bloatware, then fine-tune with virtual memory adjustments and visual effects optimization.

Regular maintenance prevents memory usage from creeping back up. Monitor your system weekly, restart when memory usage exceeds 85%, and consider hardware upgrades when software optimization reaches its limits. These techniques can reclaim 1-3GB of RAM and provide noticeable performance improvements for daily computing tasks.
