Let there be light!
You probably need to tell your Win 7 to also index the \Windows folder and its subfolders.
I agree with you in one sense. I would like to see everything be the default, but then probably many would complain about the size of the search index and the time required.
This little line will show you where your dumps are located:
enter following and hit enter
wmic recoveros get /all /format:list > %userprofile%\desktop\dmpinfo.txt
enter, followed by hitting enter:
You will see that you have a file called dmpinfo.txt on your desktop.
Control Panel | Indexing Options | Modify button |
expand the folder for your system drive and checkmark the folder that holds your dump file. I checkmark the entire windows folder but that's your choice.
