My wife has a 2 year HP laptop. It came with Windows 8. I had an old licence of Windows 7, and installed it. Don't know if I still have the CD, but defiantly have the PC with presumably the code with the original Windows 8 licence.
Over time, slow....
Today, she did the Windows 10 upgrade, and conditions are about the same.
Planning on reformatting the hard drive and performing a fresh install.
What are the steps to ensure I have a legal Windows licence?
Also, I am sure I could look it up, but any links to a good tutorial or advice would be appreciated.
