- Open Computer.
- Right click the C drive (the active drive that contains the Windows system folder)

You can write a batch file to run these commands via the scheduler for automation,
- Disable WinRE (Open elevated command prompt and Run: “reagentc /disable”)
- Take system image backup
- Enable WinRE (Open elevated command prompt and Run: “reagentc /enable”)
The "USN journal" fix does not work on 2012, since Windows Server 2012 does not allow you to assign the EFI or Recovery partitions a drive letter. But also I have not tinkered with diskpart to see if it's possible via the command-line.
Apparently there is an errant Windows Update that just recently came out, since many people are having this issue but there's no official hotfix.
