The CBS log is free of any indications of errors (obviously, so is the SFC scan!)
The messages you are seeing are absolutely normal - please don't think otherwise!
ALL real errors are flagged as such.
Some minor errors are flagged as 'Warnings'
mostly, anything else, that is not directly related to an error message can be ignored.
The word 'error' doesn't even appear in your new log.
The word 'warning' appears once - as
Line 16: 2014-05-01 13:11:57, Info CBS SQM: Warning: Failed to upload all unsent reports. [HRESULT = 0x80004005 - E_FAIL]
This is perfectly normal - and is simply because the system attempts to send reports before the full OS is properly completed loading - and the firewall gets in the way (amongst other things - I'm not even convinced that networking is switched on at that point!)
The word 'fail' appears in only two other lines - prior to the one above in the boot process, and probably for much the same reason.
In the words of my grandfather - "Dinna fash yersen, sonny!" :)
Just for grins - what are the current content of the Pending folders?
