The history of these files is stored in the folder listed in the small dump directory (% SystemRoot % \ minidump. In Windows XP and Windows Server 2003, small memory dump files are used for Windows Error Reporting. To modify the Registry to specify a small memory dump file, set the crashdumpenabled DWORD Value to 3. For example, type the following information at the command prompt, and then press ENTER
Key:

WMIC recoveros set debuginfotype = 3

To modify the Registry to specify that you want to use the D: \ minidump folder as the small dump directory, set the minidumpdir extensible string value to D: \ minidump. For example, enter the following information at the command prompt and press Enter:
