Where not opening and then i run sfc /scannow in cmd it shows windows found corrupt files but unable to repair.Then i run DISM commands but restore operation where fail.Then i decided to reset windows 10 through windows settings reset this pc and i started it while it was resetting it shows undo all changes and it went back to same state.So, i reseted windows to factory state from support assist OS recovery tool and it reinstalled windows 10(same version with software that laptop came)  but as i opened supportassist after on screen  installation process it showed hardware issue found.Issue was High definition Audio controller not found.Then after re-scan of hardware no issues found but it didn't scan HD Audio controller.Now after all windows 10 20H2 updates i tried to create system restore point but system protection on C: drive was off so, to turn it on i clicked on configure and as i clicked turn on system protection a warning message was show.The message was " Using system protection on a drive that contains system image backups will cause other shadow copies to be deleted faster than normal" .How to fix this Please help and also after factory installation when i run sfc/scannow in cmd it shows windows found corrupt files and automatically repaired them.I am thinking even on factory installation it has corrupt files why? Please tell me how to fix that warning while turning on system protection.Please help me .So,i do reinstallation of windows manually with all drivers.
