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.
