Hmm. Indeed. It's rare but possible. However, I ran some more tests and it seems uninstalling the bloatware that came with my laptop is the main culprit. Except, it's also happened once with a clean install as well, mainly overlapping ownership errors which are fixed as a result of the scan.
Thanks. I'll run it tomorrow. Stay tuned.
Partly true, but it is concerning if it occurs after a clean installation or a factory image from the manufacturer.
Whether it's significant or not very much depends on the type of errors SFC finds and fixes.

Microsoft seem a bit lax sometimes in checking their builds before release.
Thanks. This is good to know.
Thanks. Good to know.
SFC says that it found and fixed errors. If you open your C:\Windows\Logs\CBS\CBS.log in Notepad and search for "twice" I'm willing to bet you'll find that the only errors it fixed were "owned twice or has its security set twice" ones, like mine in post #8. As I said, this type of error is typically found after an update, but has no significance. As the next line says, the new owner SFC resets it to is invariably the same as the original owner.
There are two types of error SFC may find and fix. The first is the trivial ownership/permission one I described above. The second is replacing corrupt files with good copies from the component store. This second type may indeed take several runs before all corruption is fixed.
