mat-debug-xxxx.log files

I have the same problem. After reading most of the replies I emptied the temp files. Then I opened Microsoft games, played a game, closed the program and went back and opened temp files again. There was a mat-debug file back there!

It would be interesting if this same procedure would have the same result with anyone else out there. At least we'd have an idea where the mat-debug files are generated from.

That sounds a good idea. I looked at the installed programs and there's one called "Office" (not "Office Hub") and I've removed it. Let's see what happens.

The msconfig trick didn't work - I found a load of mat files today.

Well, the mat files seem to have gone away for good (famous last words). And as I don't have (and don't intend to have) office on my machine, uninstalling it shouldn't make any difference.

If you're running Office, though, it might not be a good thing to do - I have absolutely no idea.

Why are these files appearing in quantity (every 15 minutes), while running Windows 10 home, in my /apps/local/temp folder? They did not appear before the last 3 days ago.

I would still like to find out what application generates "mat-debug-xxxxxx.log" files, however.

Me too! And also to find out how to make sure it doesn't happen again.

It seems to be part of "office"  --- if you scan this thread you will find the the name of the process  that is generated the mat-debug files
