So I just reinstalled Home Premium 7 then applied the Home Premium to Professional "Anytime Upgrade". I then installed my favorite little text editor Notepad++ and everything appears to be working well except that Notepad++ is not showing up in the context menu as "Open with Notepad++".
Before I reinstalled 7 I had installed Notepad++ and the context menu relationship worked without issue. I am the administrator and I ran the installer via "Run as administrator". Any thoughts?
