OK, I'll do it!
BTW, I took Lappy to Tim the Computer Guy and had him install the 240GB SSD and upgrade RAM from 4GB to 8GB! Got antsy and installed the Anniversary Edition, but it's so easy that I'll just do it again. Total cost was $40.00! I couldn't have bought the additional RAM for that!
What would have taken me hours to do, he did in about an hour!
Going in . . .
OK, the PID.txt works with the Anniversary Edition.
Pro: I don't have to change the Product Key to update from Home to Pro.
Con: I can only use this Flash Drive with Lappy because it has its own PID now.
Tomorrow, I will see if the generic key will work, since everyone but me seems to have gone to bed and I have never used it, so don't have it.
Waiting for the test results........
I'm not sure what's going on, but when I went to the ISO link, I was offered the MCT; not what I want.
