Thanks for the feedback. I did both HP and DELL because some people like to have the SLIC match their actual manufacturer and since yours is an HP PC I figured I would do that one as well. The SLIC 2.1 in BIOS must match the Certificate but, it doesn't matter which SLP key you use as long as it is Valid and matches for your Version of Win 7 (Ultimate, Professional, etc.).
Maybe not: awdflash biosc6.bin /py/sn/wb/cc//cd/cp/ld/r/F Maybe this is better?? awdflash biosc6.bin /PY /SN /WB /CC /CD /CP /LD /E
