Microsoft seems to make features to all products.
I was no longer able to make system image backups from my system disk, as Windows had decided that my data disk had become a system disk and was to be included in the system image.
Even removing software that was installed to data disk and made to start in the image.
I tested and registered Macrium to handle the the job for future.
They offered 20% discount via Facebook message, so it was much more cost effective to just take it and use it — instead of trying to fix the Windows backup issue.
