Hi Mr.Shivam
Thanks for updating me. sfc/scannow is a command that will scan all protected system files, and replace corrupted files with a cached copy that is located in a compressed folder at %WinDir%\System32\dllcache. The %WinDir% placeholder represents the Windows operating system folder.
That specific scan will help your computer fix unwanted system files and DLL files on your Windows folder.
Have you tried running your computer with only the most essential files and services required by the Operating System.
press windows key + R
type msconfig
go to services tab and tick the "hide all Microsoft services" box.
click on disable all then apply - okay.
it will ask you to restart to apply the changes.
Thanks.
