so the keywords seem to be RACAgent and RACTask. And some
folders that it keeps. It probably does that, so a user can
erase Event Viewer, without damaging the RAC collection.

RACAgent not on my system; RacTask exists (as a 4,502 byte file -
with no extension - as the only file in
C:\Windows\System32\Tasks\Microsoft\Windows\RAC) .

This shows the size and file types of the two data folders it uses.
It keeps information in SQL Compact databases (doesn't use Microsoft
ESE Jet Blue).

My C:\ProgramData\Microsoft\RAC\PublishedData contains one file,
RacWmiDatabase.sdf, size 148 KB; my
C:\ProgramData\Microsoft\RAC\StateData contains two, RacDatabase.sdf 543
KB and RacMetaData.dat 1 KB, actually 8 bytes (AB BF FA 00 AD DB BA 00).
Still getting just the grey pillars with no overgraph.

And I see evidence here, that this thing ties into CEIP and Telemetry.
So if a program fails, it's probably reported to the software developer.
And RAC is keeping statistics.

The machine I was looking at was "polluted" by a Visual Studio
installation, so I have to be careful to not jump to too many
conclusions. But the stuff looks "complicated at the edges".

There is a RAC Engine DLL that does some math or something, but
I can't figure out much else.
