Provides commands to manipulate lines in the AUTOEXEC.BAT file. The section name, update-autoexec-section-name, must appear in the UpdateAutoBat item in an Install section of the INF file.
Not all item types shown in the preceding syntax are needed or required in an Update Autoexec.bat section. The section can contain as many CmdAdd, CmdDelete and UnSet items as needed, but only one PrefixPath, RemOldPath and TmpDir items can be used in an INF file. The syntax and meaning of each of the item types is described in subsequent sections.
The installer processes all CmdDelete items before any CmdAdd items.
