I then set CWDIllegalInDllSearch = 0 (supposedly no different from the default system). This seemed to fix it, until 10/13/10 when it crashed again. At that point I uninstalled WindowsXP-KB2264107-x86-ENU.exe. No more DEP errors.I did not try adding explorer.exe to the DEP exception list. My DEP is set to "all programs & Services".My computer is a stock Dell Inspiron 530.Anyone else had this issue??1 person needs an answerI do too

Hi tdwzxe7q, · Is there any specific purpose to make the registry changes? You may want to perform a system file scan to check for any system file corruptions. a. Click Start, All programs and then Accessories. Click Command Prompt.b. In the Command Prompt window type “sfc /scannow” (without quotes) and then press Enter.c. After the scan has completed, close the command prompt window, restart the computer and check for the issue. Refer to this article for more information.
