Why Windows runs out of RAM
Windows manages memory aggressively: it keeps recent files and apps in the standby list to speed up re-launching. That's not a bug, but when you open games or heavy apps you may run short on available RAM.
Many "optimizers" show fake percentages or free memory Windows instantly reclaims. What works is targeting working sets, standby and modified with native APIs.
Methods that actually work
1. Close unused apps
Task Manager (Ctrl+Shift+Esc) shows top RAM consumers. Close browser tabs and background apps before any tool.
2. Review startup programs
Fewer apps at boot = more free RAM from minute one. Optimus includes startup management.
3. Real freeing with Optimus
Optimus runs documented Windows operations:
- Empty process working sets
- Purge standby list (most effective)
- Flush modified pages
- Clear system file cache (optional, requires admin)
Measure before/after with memory breakdown. No telemetry or subscription.
What to avoid
- Tools promising "50% more RAM" with fake animations
- Online services asking for remote PC access
- Disabling paging without knowing the impact
Recommended steps
- Download Optimus (installer or portable)
- Run as administrator for advanced features
- Open the RAM module and review standby/modified
- Select operations and confirm
- Compare results in the live monitor
FAQ
Does freeing RAM harm Windows? Not with reversible operations like Optimus uses.
How much RAM should I free? It depends. Focus on real standby recovery, not a fixed number.
Is it free? Yes. Optimus is free and local.
