I tried the method for reenable Skip Ahead. It works and it's downloading and installing. No problem here.
Damn... in the middle of installing it reverted back to previous build (16273). Tried twice. I am creating ISO , if upgrade fails, I will do a clean install. Such a waste of time.
Just got home. Clean installed 16278 yesterday, and changed registry to get Skip Ahead update. It seems to be working OK. Will convert, and clean install again!
Yes,,, I know ... this is exactly what I am doing now and it works fine. Should have done this in the first place.
