Windows 10: Abnormally usage of cpu and disk

On my four year old i3 6th gen 4 gb ram laptop when I run any app/software the cpu and disk usage goes from 90 to 100% for a few seconds. Sometimes this happens even if the app / software is not run. What is the solution

Abnormal CPU Usage

Hello, I am currently running my laptop from Safe Mode where my problem does not persist. Last Thursday, 31st of January, for the first time ever, a few minutes after my PC booted up, I saw the CPU usage icon pop up in the little corner with the other
icons where you see it usually pop up when there's high CPU usage, but it was there for no reason. I mean, other than Chrome running a YouTube video page, I had no other application that I executed. What happened then was, the CPU usage jumped between random
numbers and I experienced slowdowns, until it reached 100% of CPU usage, and the PC crashed. I tried rebooting. Even when I don't do anything at all other than turn on my PC in normal startup, the CPU usage continues to jump a few minutes after startup, jumping
in random numbers of percentages before reaching 100% CPU usage, and then the PC crashes. This persisted this Friday and only in Safe Mode it's not happening. This is new problem for me that I have yet to come across and I don't know what might be the cause
but I have some suspicions. I noticed particularly that the TrustedInstaller service seems to me to be acting abnormally and taking up some higher CPU usage or memory, but I might be wrong. I think I might be right about this because I've noticed that when
I clicked the TrustedInstaller properties to go a directory that's related it, it was created right then, on the 31st of January, i.e. this Thursday, after snooping around a bit more I've seen that some Windows Update files have also been created that day.
Now I recall seeing TrustedInstaller much earlier before Thursday and having no problem with it or related to it for a long time, I think I noticed that this service exists sometime last year, so it appears odd to me that it tells me that all of that has been
created last Thursday with no prior history. On top of that, I seemed to experience abnormal internet connection, random disconnection every ten minutes or so, before immediate connection again, again all happening from this Thursday.

Even further than that and also adds on to the abnormality is that, as I try to type this message, when I type every several letters that I type, the position that I'm typing from changes, it jumps to somewhere on some earlier line that I typed. Only
noticed that now as I'm typing.

Piecing all the pieces of the puzzle together, I suspect I might have malware or a virus, perhaps some sort of highjacker (?), on my computer. However this explanation seems to me unlikely to be the case, because on this laptop I have not once ever willingly
accessed any dodgy website and always kept my anti-malware and anti-virus softwares turned on, along with the Microsoft Security Client, and I never downloaded an untrustworthy file on it either. And when my security tools did block potentially dangerous websites
and files, I avoided them.

Hi,

Sorry to know that you had multiple issue with Windows 10 and had to reinstall twice to resolve the issue. I also appreciate the troubleshooting steps you have tried to resolve the issue. However you can check that CPU performance by knowing what background
services are running to know that follow the steps below.

• Right click on Taskbar and select Task Manager.
• Click on Performance Tab and Click on Open resource monitor.
• Tap or click on CPU tab.

Hope the above information is helpful to know the CPU usage. Do let us know if you need further assistance.

Thank you.
