Unable to Install Cumulative Updates with error 0x800703f9

Hello

For about a few months, I've been unable to install the Windows 10 Cumulative updates and an update for windows 10.

I get the following messages every time I try to update

Cumulative Update for Windows 10 Version 1607 for x64-based Systems (KB3176938) - Error 0x800703f9

Cumulative Update for Windows 10 Version 1607 for x64-based Systems (KB3190507) - Error 0x800703f9

Cumulative Update for Windows 10 Version 1607 for x64-based Systems (KB3201921) - Error 0x800703f9

Update for Windows 10 Version 1607 for x64-based Systems (KB3176936) - Error 0x800703f9

After searching around for the error code, I've found several suggestions both on this forum and other forums.

I've tried these set of solutions

FIX: 0x800703f9 Windows 10/11 update error

The windows update troubleshooter simply deletes the installation files and the same problem occurs again.

Trying the SFC /Scannow command brings some problems. I get the message that "Windows Resource protection could not perform the requested operation" I think I did manage to successfully run the check in safe mode.

I have tried chkdsk, and everything is working fine.

I have tried the commands for Dism /online /cleanup-image /scanhealth /restorehealth

and get the following error. I can provide the log file.

[== 4.5% ]

Error: 1017

The system has attempted to load or restore a file into the registry, but the specified file is not in a registry file format.

I believe something maybe corrupt within the system.

If anybody can help me out, I'd be grateful. I enjoy not having to have my computer forcibly restarted by windows update, but would also like to try the new features such as the blue light filter.
