I bought a new Dell inspiron 2 weeks ago. One day all the default apps disappeared with no reason. I went to my university technology center for help, and they reinstalled the windows 8 for me.
However, the computer I bought is pre-installed with window 8.1. But now my computer is windows8. Here is the problem. I cannot activate the windows. And I could not find product key for my windows because Dell said it was injected in the computer.
