Hello microsoft community,
My mom bought an old laptop at a thrift store. After a while it started saying it had an illegitimate copy of windows 7. It also got a limited interfact which was mostly black and white, and there were some options I couldn't click on. Through school we got a legitimate product code for windows 10 education. After doing an upgrate with that code, we still got the same weird, limited interface. What can I do to get a normal windows 10 interface? The laptop is a dell latitude d830.
