I think I may have some corrupt files in my Windows 10 Home operating system.  I can't run the Disk Defrag program when I try (it just says, "Optimization Not Available) and I just tried to update the OS to the newest Windows 10 2004 but it failed. 

I understand there is a program that scans your OS looking for corrupt or missing files and then fixes the.  I guess it's called SFC System File Checker.  How to I go about running this to check/scan my operating system.  What is the process to run this?

I did do a Thorough Virus Scan (not the Quick Scan) and no viruses were found. Also, I'm not getting a error message or beeps and startup is slow but does boot OK.

Hi,

The factory installed disk is a platter HDD so optimization normally applies to a SATA SSD or M.2 SSD.

You should be able to defrag the drive.

I would run HP boot time diagnostics to check the drive for possible hardware errors. Tap "ESC", the "F2", then run system tests or see here (Link) for running HP Vision Diagnostics from a CD/DVD if needed.

You could also check file integrity by running the following items:

Open an Administrative command prompt (Type command prompt in search, right click on search result and select run as administrator) then enter DISM.exe /Online /Cleanup-image /Restorehealth

After this completes enter sfc /scannow

Your HDD may be failing.

The latest version of W10 may not be compatible with your circa 2011 PC. You may have to replace the HDD.
