Alright so let me explain exactly what has happened. I bought and built my brand new gaming PC, and of course needed Windows. From a trusted website, I bought a $60 Windows Home OEM key. After typing in the key and downloading Windows, it told me I needed to restart. I restarted, and being ignorant I was unaware that I needed to boot from my hard drive this time to activate Windows. Instead, I typed in the key again (being confused) and it told me it was going to move my old Windows into a windows.old folder. I didn't really know what that meant, so I continued anyway. The next time I did it I remembered I needed to boot from the hard drive after downloading, so I did that. Two days into having this, I'm now getting annoying little watermarks on my screen saying "Activate Windows". I believe this is because I typed in the key multiple times and downloaded it multiple times. Is there a chance I can get to windows.old and boot from there? That has the ORIGINAL key, and these messages are very annoying. It also restricts me from personalizing my PC, and I don't want to have wasted $60 to a simple mistake. Thank you for your help in advance.
