Hi there and welcome
How exactly did you do the recovery and what is the make and model of the computer?
How exactly did you do the recovery?
ok, but they do not come with disks so looks like you used a disk from another installation which explains the issue.
You need to do the recovery this way
Power off the notebook
Then power it on and keep tapping F11 until you get to the recovery manager. If it does not get to this, repeat using F10 instead.
Once there, choose to do a factory reset
Let this complete and when it has it will have the version of windows that is was designed for.
The Key is specific to the actual disk, so it is not possible just to give it out.
Let me know how you go please.
