If Microsoft Office 2013 is installed on a PC and you need to know the product key, but there is no product key sticker on the system, you can obtain the product key from a command prompt using the command
cscript “C:\Program Files (x86)\Microsoft Office\Office15\OSPP.VBS”
/dstatus
for the 32-bit version or
cscript “C:\Program Files\Microsoft Office\Office15\OSPP.VBS” /dstatus
for the 64-bit version. If Microsoft Office is installed beneath
Program Files (x86)
that indicates you have the 32-bit version,
since that is where 32-bit versions of applications are installed.
But you will only be shown the last 5 characters of the 25-character product key, because, unlike with prior versions of Microsoft Office, Microsoft is no longer storing the entire product key in the registry where it can be retrieved. So the product key you obtain is only likely useful to you if you have multiple Microsoft Office 2013 product keys and need to determine which one is used on which system. Or if you purchased the software online and received the product key by email, you could use those last 5 characters to search your email or your system for any message or file containing the full product key.
When you run the commands, you will see output similar to the following:
C:\>cscript "\Program Files\Microsoft Office\Office15\OSPP.VBS" /dstatus Microsoft (R) Windows Script Host Version 5.8 Copyright (C) Microsoft Corporation. All rights reserved. ---Processing-------------------------- --------------------------------------- SKU ID: 064383fa-1538-491c-859b-0ecab169a0ab LICENSE NAME: Office 15, OfficeProPlusR_Retail edition LICENSE DESCRIPTION: Office 15, RETAIL channel LICENSE STATUS: ---LICENSED--- Last 5 characters of installed product key: B96XY --------------------------------------- --------------------------------------- ---Exiting-----------------------------
If the software was preinstalled on the system, there is likely a sticker with the full Microsoft Office 2013 product key. But, if it wasn't and you need the full product key, but can't find it via a search through email or files on the system, if you registered and activated the software, you may be able to log into a Microsoft account that you have via Microsoft Office: My Account. You should be able to see the product key there and redownload the software, also, if needed. A last resort might be to contact Microsoft support using contact information from Microsoft's Contact Us page. But you will likely need some way of proving that you purchased the software to have any chance of being issued another product key.
