● 参考解析
Winnt32.exe/unattended:setup.inf will start an unattended installation using the answer file setup.inf. When ReportOnly=Yes is added in the [Win9xUpg] section of the answer file the installation only generates an upgrade report and then exits without making any changes to the current Windows 95 or Windows 98 installation. The upgrade report contains a list of hardware and software incompatibilities and is saved to the root of the system drive if the SaveReportTo key is not specified.
