A day before, I am trying to pre-configure my Windows installation disc. I noticed that there is a file located in the disc that has the Product key. It contains information about how to automate the installation or upgrade so the setup runs without requiring user input.

Where is it?
Open windows explorer and go to the [discdrive]\I386 folder, browse for "Winnt.sif" file and drag it to notepad...

^^^^^ No no.......

vishalgmistry means the discdrive i.e. Win XP CD

Thr is a folder called i386.

Not our C:\ drive

Use this software to find keys of installed software:
ProduKey - Recover lost product key (CD-Key) of Windows/MS-Office/SQL Server
(this is perfectly legal)
