System.ini Settings in the Registry

Entries from a System.ini file in 16-bit Windows 3.x on the computer when you install Windows NT are preserved as entries under this key:

\Microsoft\Windows NT
\CurrentVersion
\WOW

Table 26.2 describes where you can view or edit entries for similar purposes in Windows NT. These entries are used by applications that look for values in the System.ini file.
