Hello JMKVerma,
Please ask your systems administrator to logon to the eOpen site (https://eopen.microsoft.com/EN/default.asp) and confirm what your assigned VLK is for either Office or Windows. From here they will be able to determine which software they have licenses for and their respective product keys. Should you have any further questions please feel free to reply to this thread.
Thank you,
Matt Prall, MS
