Inactive System Process

On Windows NT operating systems, the inactive system process contains one or more kernel threads that run when no other thread can be scheduled on the CPU, but simply the percentage that the processor is not working. For example, when no process is running or all processes that are in this state are being executed on other CPUs. In a multiprocessor system there is a thread for the idle state associated with each CPU.

Inactive system process threads are used by Windows NT to implement CPU power savings. The energy that can be saved depends on the hardware and the compatibility of the firmware with the system in question. For example, on x86 processors, the inactive thread will execute HLT instruction loops, which cause the CPU to disable some internal components waiting to receive some IRQ.

The CPU time consumed by the inactive process of the system is of interest to the end users, since this can serve as a utility to measure the time of use of the CPU being easily accessible through the task manager. / p>

In case of memory overload and slowing down the pc, even if this process is> 95%, then it may be the work of some virus, such as Blaster, for which you need to install some antivirus tool , anti-malware or firewall to start the system in safe mode and try to repair some damaged file.
