That pseudo-start menu works fine as long as you only have a few dozen applications. Beyond that, you realize why you've always organized your programs by function, not alphabetically.
My biggest complaint with 8.1 is that it goes out of its way to hide the actual pathnames of executables. It used to not matter whether you knew the real location of a file because you could usually find it in the Start Menu.
This morning I wanted to add a shortcut to Remote Desktop into a folder, but I couldn't remember the name of the executable (it's mstsc.exe, duh). So I had to locate and run it via the Search bar, open Task Manager to discover the actual pathname, and then manually type it into the shortcut. In previous Windows versions I'd have simply dragged it from the Start Menu.
If W10 turns out to be as solid internally as 8.1 but brings back the damn start menu, then I'm onboard! But I'll wait a few months - I got tired of being a pioneer 20 years ago. Anybody else invest six months learning Xenix? It was the Next Big Thing c. 1985. Nope, my pioneering days are done.
