Hi, I am a new member.  I am looking for suggestions for cleaning up the source of a Data Execution Prevention action triggered by Generic Host Process that when interrupted says EventType BEX in the accompanying message (see below for detail). What I have seen on the web is that the most likely cause is HP printer driver or other software. I plan to reinstall HP software for  an OfficeJet 7310xi unless others might know more and suggest otherwise.  Thanks in advance if you know something about this kind of issue. The symptoms of the problem were on startup the appearance of multiple Data Execution Prevention (DEP) messages from the previous Win XP session with a request to send info to MS and also that Windows Explorer took a very long time to find disk drives, folders and files when started up.   I have a workaround for the symptoms in disabling WIA (Windows Image Acquisition) in Services.  That stops the DEP messages at the next login and makes Windows Explorer fast again. Here is more of the detail from the message I get if I leave WIA on automatic or manual rather than disabled: EventType : BEX     P1 : svchost.exe     P2 : 5.1.2600.2180     P3 : 41107ed6 P4 : unknown     P5 : 0.0.0.0     P6 : 00000000     P7 : 009a9eec      P8 : c0000005     P9 : 00000008      Error report will include files C:\DOCUME~1\Jim\LOCALS~1\Temp\WER9fd2.dir00\svchost.exe.mdmp C:\DOCUME~1\Jim\LOCALS~1\Temp\WER9fd2.dir00\appcompat.txt When I open appcompat.txt I see the following except that I deleted the additional  information beyond the SIZE data: <?xml version="1.0" encoding="UTF-16"?> <DATABASE> <EXE NAME="SYSTEM INFO" FILTER="GRABMI_FILTER_SYSTEM">     <MATCHING_FILE NAME="advapi32.dll" SIZE="616960"      <MATCHING_FILE NAME="gdi32.dll" SIZE="282112"      <MATCHING_FILE NAME="kernel32.dll" SIZE="984576"      <MATCHING_FILE NAME="ntdll.dll" SIZE="708096"      <MATCHING_FILE NAME="ole32.dll" SIZE="1285120"      <MATCHING_FILE NAME="oleaut32.dll" SIZE="549376"      <MATCHING_FILE NAME="shell32.dll" SIZE="8454656"      <MATCHING_FILE NAME="user32.dll" SIZE="577536"      <MATCHING_FILE NAME="wininet.dll" SIZE="824832"      <MATCHING_FILE NAME="winsock.dll" SIZE="2864"  </EXE> </DATABASE> The good news is that the message is always the same.
