win系统cpu温度获取

基于win 系统的cpu温度获取，用底层驱动来读取cpu温度寄存器的数值，注意，一般网上用到的WMI方式是无法获取cpu温度等信息的，这涉及到win系统的权限，而且，WMI是从BIOS主板上来读取数据的，基本上生产商不会把cpu温度，显卡温度等信息写入BIOS 中，而且写入的还是一个固定值，也就是说，cpu温度不会变，本人也尝试了很多方法，最后得出结论，只用通过底层去驱动才能时刻读取cpu温度的准确信息，现将代码和，文件直接贴出来以供大家学习和研究，，注意本文是在VS上编辑运行的需要自己下载WinRing0.sys 。WinRing0x64.sys。WinRing0x64.dll 。WinRing0x64.dll 系统权限访问库
