Hello today I go to my laptop and all I get is "This Copy of Windows is not Genuine". So I took a look around and did a reboot and noticed this error "Serial Number not Found" in the top right hand corner. So I went into my BIOS settings and towards the bottom there are a few things. UDID id and such, all that are zeroed out. I've looked around the forum and found this thread "SLP Marker File Update Utility". I was wondering if it would be possible to use those tools on my laptop and what steps would I need to take. Thank you anyone who helps this laptops been with me for at least 5 years now and I can't afford a new one or sending it in for repairs.
