I couldn’t find any info on how to get this information easily, so I wrote an analysis to retrieve some data from the Windows Licensing and Office Software Protection Services. Since most of these properties are collected via WMI, you may want to extend the report interval, some are at once a day, some once an hour.
I found it for to find out what KMS servers your windows Vista/7 or Office 2010 installations are using, and if they are succesfully activating. Hopefully some of you will find it useful as well.
Included properties:
Names of licensed products
Product name of the installed products.
License State
One of the following license states: OOB Grace|Licensed|OOT Grace|NonGenuineGrace|Notification
I guess the relevance for the OS Analysis should really read like this …
name of operating system starts with "Win" and release of operating system as version >= "6.0" as version
That will cover Vista/Server 2008/ 2008 R2/ Win7, and whatever comes next. The relavance for the Office Analysis will already cover any version greater than or equal to 14, which should cover the next version of office too. That is if Microsoft continues to use the same licensing platform.
