Regarding question 2...
While not a definitive resource, considering everything I have read
about file dates there are only 4 dates kept for files. I would assume
that LastWriteTime would equate to the last time the file was modified.
ChangeTime would equate to the last time the file's entry in the MFT was
changed.

Subject: Two Windows questions
All,
I've got a couple of questions, primarily for clarification. After
researching these both for a while, I'd like to try to get some more
definitive information...
First...the UserAssist\{GUID}\Count keys:
http://personal-computer-tutor.com/abc3/v29/vic29.htm
Does anyone have any specific information (ie, definitive source)
available on what kinds of activities result in entries in these keys?
My second question refers to the FILE_BASIC_INFORMATION structure:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/kmarch/
hh/kmarch/k112_3de98e8c-d842-45e9-a9bd-948276ef1b87.xml.asp
The structure is described as:
typedef struct FILE_BASIC_INFORMATION {
LARGE_INTEGER CreationTime;
LARGE_INTEGER LastAccessTime;
LARGE_INTEGER LastWriteTime;
LARGE_INTEGER ChangeTime;
ULONG FileAttributes;
} FILE_BASIC_INFORMATION, *PFILE_BASIC_INFORMATION;
Does anyone have a definitive resource that specifies the difference
between the LastWriteTime and the ChangeTime? I've looked at MSDN, in
Brian Carrier's book, and via Google...input would be greatly
appreciated.
Thanks,
