My thinking is that is someone told him to delete X, Y and Z from the registry, perhaps going back to them for help would be a good idea.

Why, it was deleted might give us a clue as to any other issues that can cause the same problems.

What, would tell us more about what was done.

Agreed. The answer re malware removal or the like is a common enough reason & has been attempted by some at one time or another. Long ago, I also found out the hard way messing around with the OS registry without backing up and/or knowing exactly what you're doing is a no no. lol

Many years ago people would come here first asking about regedit, and the answer would be don't mess with it. Unfortunately there are so many other sources now that they come here afterwards and those giving the advice are not available to ask about their advice,
