[[Windows error dumps are typically named MINI000000-00.DMP and are 64KB in
size. The 000000-00 part of the name is month, day, year (2 digits) and
sequence number for that date (mmddyy-##). You can configure the type of
memory dump performed by Windows. Please see the details in the Microsoft
Support Article. With regard to memory dumps...if it happens regularly or
happens when you run a particular program then you should contact either
Microsoft or the program's support group to tell them there is a problem and
try to work with them to determine what it is. Support may need the file or
details from it.]]

[[What Is a Minidump?
A minidump is a file containing the most important parts of a crashed
application. It is written on the user’s machine and then the customer can
submit it to the developer. The developer can load the dump to help
determine the cause of the crash and develop a fix.]]

appcompat.txt shows up in a temporary folder.
C:\DOCUME~1\Owner\LOCALS~1\Temp\WER9.tmp.dir00\appcompat.txt
C:\DOCUME~1\Owner\LOCALS~1\Temp is a temporary folder. Empty it.
The appcomp.txt file is created when there is a conflict between programs,
drivers, etc. It is a reporting file used when uploading error reports to
Microsoft. Appcomp probably stands for Application Compatibility.
If you do not want to see appcomp.txt again, disable Error Reporting.
Open System Properties...
Start | Run | Type: sysdm.cpl | Click OK |
Advanced tab | Error Reporting button | Check:
 Disable Error Reporting | Check:  But notify
me when critical errors occur | OK | Apply | OK
Disable Error Reporting
[[Select to disable error reporting. When this option is selected, error
reports will not be generated.]]
But notify me when critical errors occur
[[Select this option to have Windows notify you when a critical error
occurs, even if you have disabled Error Reporting.]]

We see a pop-up box when we turned on our computer (WinXPsp2) and did we
want to send report to Microsoft. We were offline; so we did not send.
The report was, as follows, and wonder if someone might be able to tell us
what caused it. (We are already receiving a Blue Screen when we sign on.)
Thanks, Bob
