After releasing of Windows 10, Several users have reportedly been complaining on various forums about memory leaks because of ntoskrnl.exe high CPU usage. When I checked, in several systems I found that correct. I found ntoskrnl.exe usage 400-500 MB of RAM without any opened applications that slow down whole PC.
This type of problem is one of the biggest reasons for the slowdown of the system along with memory leakage problems, as most Windows 10 users are likely to have upgraded their existing Windows 7 or 8.1 instead of opting for a clean installation. There may be many methods to solve this issue but all are lengthy and not trustworthy. After some research I found a correct answer of this question. I will show you the quick fix of this memory leak issue.
