[BillyJeans]

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.

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.

Hi and welcome to Synative,

There are a few things to repair, here's the first fix.

Step 1. Download

SFCFix and save it to your desktop.

• Save any work you have open, and close all programs.
• Download the attachment SFCFix.zip and save it to your desktop.
• Drag the SFCFix.zip file over the SFCFix.exe executable and release it.

• SFCFix will launch, let it complete.
• Once done, a file will appear on your desktop, called SFCFix.txt.
• Post the logfile (SFCFix.txt) as attachment in your next reply.

Step 2. Run the following DISM command and post the result. If it fails attach a new copy of the CBS log.

DISM /online /cleanup-image /RestoreHealth

Thanks for your reply!

Step 1. Complete I have attached the file.

Step 2. The restore operation completed successfully!

Should I try and add the Hyper V role now?

 

[Maxstar]

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.

Run also

ComponentsScanner again.

• Right-click ComponentsScanner.exe and select "Run as administrator", click Yes on the UAC (User Account Control) prompt which appears.
• Follow the on-screen instructions.
• Once complete, a report will be saved to your desktop called ComponentsScanner.txt.
• Post the logfile ComponentsScanner.txt as attachment into your next reply.

 

[BillyJeans]

The feature failed the reference assembly could not be found. I have attached the log file.

 

[Maxstar]

Thanks, please post also the result of ComponensScanner in your next post along with the result of FRST.

Download the

Farbar Recovery Scan Tool and save it to your Desktop:
