Windows – what could be cause of the slow running laptop on windows 10

performancetask-managerwindows 10

I am having a laptop which has 12 GB of RAM.
Intel Core i3-60060 CPU 2 Ghz
it has become extremely difficult to use this laptop for some unknown reason.
I am attaching a couple of screenshots which I could capture please see and help me to understand what can I disable so that I can use this efficiently or else I have plans to format this machine completely and put Ubuntu on it if nothing works. This is my last try with windows due to documentation purposes I have to use Microsoft office and a few software which I find difficult to work in Linux like Psiphon I am still using Windows 10 on it.

I read a guide here
What is the problem please let me understand.

as per comment I am updating taskmanager column with memory in priority
task manager with memory high

based on comments below I executed the dism commands

dism /online /cleanup-image /startcomponentcleanup 
dism /online /cleanup-image /restorehealth

first command above took 1 hour to execute.
second command above took 3-4 hours to execute.
reboot no issues found/corrected

sfc /scannow > reboot  

no issues found.
After reboot and a using for 1 day reboot and shutdown and restart.
I am posting screenshots of resmon.exe

The first screenshot below I have selected threads column to show maximum to lower threads in output.
resmon.exe 1
The second column is based on commits column in resmon.exe output i.e. highest or maximum number of commits at top and then in descending order.
resmon.exe 2

this third screenshot below is sorted on basis of CPU column of resmon.exe that is the highest CPU utilization at the top.
resmon.exe 3

I scanned with advanced system care here are the logs
I am still debugging it will try Ubuntu from Live USB stick and post results here.

Best Answer

It looks like Microsoft Edge is taking most of the resources, but before concluding on that, you might be having malware which is running in the background and consuming most of the resources.

Try running the malware scan.

Hope It helps,
