Hello,
I am running a windows server 2016 machine. I have been attempting to install Hyper V role and it keeps failing. My log file gives me the following errors.

CBS Failed to pin deployment while resolving Update: Package_6923_for_KB4493473~31bf3856ad364e35~amd64~~10.0.1.10.4493473-15294_neutral from file: (null) [HRESULT = 0x80073701 - ERROR_SXS_ASSEMBLY_MISSING]

I followed the requested steps in "Windows Update Forum Posting Instructions."
#1 Step
sfc /scannow

Windows Resource Protection found corrupt files but was unable to fix some
of them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For
example C:\Windows\Logs\CBS\CBS.log. Note that logging is currently not
supported in offline servicing scenarios.

#2 Run SURT/DISM

Dism /Online /Cleanup-Image /RestoreHealth

Error: 0x800f081f

The source files could not be found.
Use the "Source" option to specify the location of the files that are required to restore the feature. For more information on specifying a source location, see Configure a Windows Repair Source.

#3 Components scanner
I ran the components scanner

#4 - Export CBS Folder
Attached File

From other threads I ran the FRST64 scan feature for the KB and searched the registry but need help with the fixlist.txt. I have attached the Search reg Files for KB4493473 and i searched for it via C:\Users\Administrator>wusa /uninstall /KB:4493473

For the other error KB503585 I have attached the SearchReg File and also checked the command the following update was found. It is a security update. I didnt uninstall.

Could I please get some help.

Yes, please try to install the Hyper-V Role and if it fails (I guess it will) attach a new copy of the CBS logs.
