Here is a new HP SLIC table and certificate retrieved from a HP custom desktop with pre-activated Vista Ultimate. HP = "HPQOEMSLIC-CPC" HEX = 48 50 51 4F 45 4D 53 4C 49 43 2D 43 50 43 OEMCERT CRC = 573FCB8E As you can see it is almost identical to HPQOEMSLIC-MPC. The difference being "CPC" vs "MPC". I did a byte for byte comparison between the two SLICs and found that the PUBLIC KEY is the same but the MARKER is different (of course the header was also different as you can see). Interestingly, both SLICs use the same certificate. The key retrieved from this machine was the *R933G key. I tested it in VMware and it works. Enjoy. Another interesting point. The OEM sticker on this machine actually had a different product key printed on it than the key retrieved from the machine. The key on the sticker was a OEM-COA Ultimate number. So, I don't get it. Why would HP install a OEM-SLP Ultimate then affix a OEM-COA Ultimate sticker on the machine. Does this mean the OEM-COA number is unused??
