令人困惑的是， JLinkx64.sys 在众多其他电脑上从未引发过类似问题。经过开发者长达半个月的逐一排除，最终锁定了真正的冲突方——（英特尔串行IO驱动程序）。当Intel Serial IO GPIO Host Controller驱动安装后，反复插拔J-Link就会导致蓝屏；而卸载该驱动后，问题随即消失。 jlinkx64sys
While the concept of JLinkx64Sys presents exciting opportunities, it also raises concerns. Deep system access necessary for such tools could expose vulnerabilities if misused. Unauthorized access to registry settings or hardware diagnostics might lead to privacy breaches or data corruption. Additionally, over-reliance on automated optimization could depersonalize computing experiences, stripping away user agency in decision-making. Ethical questions would also arise about data collection: if the tool transmits diagnostics to third parties, transparent policies would be critical to maintaining user trust.
