I have given up trying to obtain and install the missing DLL files for 8.1. I'm just not that technical a person. So, after wasting several days, I just want to get fully functioning. Can you sketch out the steps for getting rid of the parts of 8.1 I still have, and then installing Windows 10 ? Please keep explanation of the procedure simple, and list whatever URLs must be visited to get this done right. Thanks hugely.
