Why am I getting the message: OS software is not genuine.

[Helomaniac]

My old faithful now has a black background and message that my OS is not genuine. It cam on the machine from Best Buy and has worked well for 10 years. Googled it but no advice helped. My unlock key sticker is worn to badly to read. Can anyone help other than telling me to get a new laptop? Please.
