The "radar_pre_leak_64" you're seeing is indeed a standard part of Windows 10. It's related to the Windows Resource Exhaustion Detection and Resolution tool, which helps in identifying and troubleshooting memory leaks in applications. You don't need to worry about its presence; it’s there to help ensure that your system runs smoothly by checking for potential software issues before they become real problems.
As for its impact on system performance, it's generally minimal. The tool runs quietly in the background, doing its job without taking up significant resources.
And here’s a tiny joke for you: Why don't memory leaks bother Windows? Because it has too many Windows to escape from!
