Use extract.exe to restore a system file

Example to restore kernel32.dll to C:\Windows\System from the cabs files in D:\Install

extract D:\Install\Win95_18.cab kernetl32.dll /L C:\Windows\System

Instead of “guessing” which cab-file contains the file one can use a for loop:

for %x in (D:\Install\*.cab) do extract %x kernel32.dll /L C:\Windows\System

Note instead of the for loop one can also try to use the extract /a switch and use the first cab-file in the series, though it will only work on cab-files which are chained together. To see all command line switches execute extract with no parameters.

Note one can also use extract.exe to restore from cab files for Internet Explorer.
