I suspect that there's something inhibiting the SPPSVC at times - do you have any game-optimising software installed? This type of thing has a nasty habit of blocking such services in the mistaken belief that it frees clock-cycles for the came.
The other likely cause is malware (or even your AV!)
<thinking aloud>
In the 10,000 or so MGADiag reports I've analysed in the past couple of years, I don't recall ever seeing this particular error message before
C:\Windows\system32\slmgr.vbs(1333, 5) (null): The service has not been started.
The 80070426 error is a relatively common one, but usually present in the MGADiag report - and indicates that a service couldn't start within the timeout (usually the SPPSVC).
Since your SPPSVC seems to have no problem starting manually, there should be no problem running normally unless there's interference.
As the problem only shows in the SLMGR.VBS area, it is more likely to be something associated with the scripting at that point - unfortunately my scripting skills are best described as non-existent.

Did you run the script commands in my earlier post? (SLMGR.VBS.... etc?) what happened?
I'll do some research - but I'm occupied most of tomorrow, so it'll probably be Friday before I can get back to you.
