They both are using there codes correctly i didn't have to do anything with the 7 key. The 10 i had to call the 800 number and give them those 7 digit numbers and it gave me back numbers to enter and it correctly gave me a authorized key and 10 woke up and the black screen started showing the desktop and started updating. I took out the sign in screen so it could install updates and restart as it needed. 7 didn't do much of anything. 10 woke up and have updates that seemed to started updated when i got the new key installed. Anyway, i will check it out in awhile. As for speed.. i didn't check it to much but it did seem faster, but with all the updating going on it was hard to tell. Will let you know. Later, wd66
