I recently lost my previous MDL account when lavabit went under. I rarely need to post anything, as usually the answer is in the stickies, or a previous user's post. So I just made a new account. I'd post links to what I've been reading about, but I can't due to my account not having any previous posts. Well, I've read over how AIO installation media is made, and also how to upgrade a Win 8 KMS/activated install to 8.1 using "setup.exe /auto:upgrade" ...then I found a pre-activated AIO iso file on TPB for Win 8.1 AIO so I could upgrade. I spent several hours reading about this stuff, so maybe I missed the answer somewhere. Sorry if that's the case. My questions are: 1.if I use the pre-activated installation of 8.1 from the .iso shown above, will there be a watermark problem if I don't upgrade using the method shown in VMWare by ambidav? ("setup.exe/auto-upgrade") 2. How are these AIO .isos pre-activated? Thank you for your time. I hope this question hasn't been posted too many times. I couldn't find the answers to those two questions.
