Unless it's from other than HP and other than HP usually tells you the key or is cracked pirate copies.
Anyhow there are so many posts about using the following method to get in and create a new admin account.
https://www.technibble.com/bypass-windows-logons-utilman/ works for W8 too.
But I'd do that fast as you may want to move to W10 before the deal is over.
I accuired a window 8 computer from my now deceased neighbor. So while setting it up and changing some things for my son whom i gave it to. The adminstrator was changed from within the control panel to myself and the deceased neighbor was changed the local host. So when this change was made it never asked me to create an admin password. So when we dl something it ask for a password from the admin but there is not one. I do not have a recovery disk all i have is what i believe to be the boot manager on a flash drive. I have ordered a recovery disk for the same model tower but it will not come with the product key. The original os i according to HP was windows 8 but according to the info in setting it is running 8.1.
What are my options here?
