I have a win8 laptop and a win 8.1 notebook. The OEMKEY reveal tool worked on them both but neither one has a product key sticker. I have 2 win 7 machines, both have product key stickers. The sticker on the win7 laptop has 2 characters which are illegible. WEhen using the OEMKEY reveal tool I get a message "Unable to open MSDM table". How can I get the product key for the laptop with the illegible sticker? Refering to the manufacturer may be a no go as it is a Gateway, (who are they and are they still around). Any advice would be appreciated, thanks.
