Windows: you can call GetTickCount64 to get the time since the system was started, and QueryIdleProcessorCycleTime to get idle time. Windows：您可以调用GetTickCount64获取自系统启动以来的时间，而QueryIdleProcessorCycleTime可以获取空闲时间。 Subtract to get the time spent doing something useful. 减去以花费时间做一些有用的事情。
As for HDD and RAM usage depends on what do you mean by 'used'... Number of reads? 至于HDD和RAM的使用情况取决于您所说的“已用”是什么意思...读取次数？ writes? 写？ Allocated pages? 已分配页面？ Committed pages? 提交页面？ Virtual or physical memory? 虚拟还是物理内存？ Page file requests - are they considered as HDD or RAM usage? 页面文件请求-它们是否被视为HDD或RAM使用情况？
