this post just to share experience about a solved problem:upset:.

I had to perform a clean install of Windows8 on an OEM ultrabook delivered with Window7 Pro preinstalled since I have been unable to boot the delivered Windows 8 Pri DVD Pack after converting the MBR delivered SDD to GPT (UEFI). I am still dwelling trying to reinstall some or all of the OEM preinstalled customization and recovery software, but I managed to properly partition my SDD according to my needs and booting from the SDD, and activating my copy of WIndows 8 Pro with the firmware Product Key.

After this partial success, I wanted to save the work done until now before attempting to configure a recovery image to be used from Windows RE. Therefore I wanted to use Windows Backup to my 1Tb USB HDD, which had previous backups recorded, and encountered successively in the following errors.

I noticed that I could perform a standalone system image backup without going through the backup configuration, which suggested that the problem might concern the "Libraries" or the task scheduling. Various repair suggestions like SFC /scannow and dism /online /Cleanup-Image variants were successful but the error persisted over and over again. In despair, I tried to get rid of the previous backups throu renaming the folders, deleting the schedules and the like, just to end up towards ...

    this time immediately when trying to configure the backup and meaning "specified file not found", the ubiquitous Microsoft way to tell what is missing. No suggestion helpd until I was led thru registry inspection of Backup related entries to sdclt.exe and the following post about it's command line parameters Windows Backup (sdclt.exe) VISTA/SEVEN command line parametters - And see what: the parameter /CONFIGELEV /SHOW solved the problem !!! Obviously not finding the appropriate file was due to a simple lack of privilege elevation.
I thought this post may help somone else dwelling with the Windows Backup secrets:nevreness:.
