How to set alternate location for SQL Server dumps?

To change the default location for dump files, you can add the SQLExceptionDumpPath registry key with REG_SZ type under HKLM\Software\Microsoft\<instance path>\Setup  and set the value of this key to the new path. The default location for this is the SQL installation Path\log directory.

Above change does not require restart

HKLM\Software\Microsoft\<instance path>\Setup\MaxDumps    -DWORD to limit maximum number of dumps (0=Unlimited)

HKLM\Software\Microsoft\<instance path>\Setup\MaxFullDumps to limit maximum number of full dumps (0=Unlimited)
