⚙️ System Optimization & Robustness Skill

This skill provides deep technical guidance on interacting with the Windows API safely and efficiently to manage system resources.

Exception Handling: Wrap every WinAPI call (OpenProcess, SuspendThread, EmptyWorkingSet) in robust try-except blocks.
Permission Elevation: Proactively check for ctypes.windll.shell32.IsUserAnAdmin() and handle the "Access Denied" (0x5) error gracefully.
Critical Process Filtering: Maintain a strict blacklist (hardcoded + configurable) to prevent freezing wininit.exe, lsass.exe, or services.exe.

Threaded Refresh: Do NOT run psutil.process_iter() on the UI thread. Use a threading.Thread or concurrent.futures.ThreadPoolExecutor to keep the UI fluid.
Batch Operations: When applying a preset with 10+ apps, batch the operations to avoid UI stutter.
Resource Sampling: Cache process icons and metadata. Only update CPU usage and RAM stats every 1-2 seconds to reduce the overhead of CryoTask itself.

Working Set API: Beyond EmptyWorkingSet, consider exploring SetProcessWorkingSetSize for more granular control if users request "Advanced Mode" tuning.
Verification: Always verify the result of a Trim operation by sampling the RAM usage immediately after the call (expect a significant drop).

Mock Environment: Create a script that spawns "dummy" low-priority processes to test Suspend/Resume logic without risking system stability.
Stress Test: Test the "Periodic Trim" feature over a 24-hour period to ensure no memory leaks exist within CryoTask.
