Hey all - Hoping someone can help me with the following:I had 8.1 installed when my hard drive crashed. I installed a new hard drive.My Dell all-in-1 XPS has a Windows Pro sticker but no activation code.I wasn't sure if I had 32 or 64 bit but installed 64. I was never asked for an activation code, so I thought Windows had found this in Bios.Windows told me I was eligible for - and encouraged me to - upgrade to 10.Once I upgraded to 10 I started being told I needed to activate Windows.I used a third party tool to try to find my activation code in BIOS but Windows told me it was already in use.I called Windows support and was told I needed to start again with Windows 8 Pro (not 8.1) but I can't find a version of this on the Windows site. (Can find Windows 8 or 8.1 Pro but not 8 Pro). Questions: If I start again with 8.1 Pro do I need to do something differently before I upgrade to 10? Is there somewhere I can find a safe and legal copy of 8 Pro to download? Any other recommendations of what to try? Thanks in advance!!!
