I disagree. I was using WinDbg downloaded from the Microsoft Store (so it had the WPF or whatever UI), and it was unusable. (Note: I was using it on a very large project - 4mLOC with hundreds of first- and third-party libs; It's likely I could get some use out of it on a trivial program, but it just didn't get the "real" program; and no, I wasn't simply missing the PDBs).
