Hello,

I wanted to add the server role “Hyper-V” to my Windows Server 2016 Essentials using the Server Manager. The installation aborts with error code 0x800f0831. (Yesterday we had a power failure)

SFC does not report any errors. When running DISM... I get the error 1734.

FRST Registry Search

  3. When command prompt opens, copy and paste the following command into it, press enter afterwards.

    Code: 
    REG LOAD HKLM\COMPONENTS C:\Windows\System32\config\COMPONENTS

    Note: This loads your components hive which is what we want. Please keep the command prompt window open while you perform the remaining steps. You can minimize it if you wish but keep it open.
  4. Download the Farbar Recovery Scan Tool and save it to your Desktop:

    Note: Your antivirus program may report FRST incorrectly as an infection. If so, disable the real-time protection when downloading and running FRST.
  5. Right-click on the file FRST64.exe and choose Run as administrator.

Hi,

after both sfc and DISM were successful, I tried to install the Hyper-V server role with the Server Manager.

It ended with the error 0x80073701.
