All sorts of data corruption possibilities.

Even after UNIX finally added support for file locking, its use relies on all processes making use of the API, if they don't care, they get to access the file anyway.

What angers UNIX users about file locking on Windows, is actually how proper file locking is done outside of UNIX, Windows is not alone in that regard.

As a self identifying Unix user, what angers me about file locking on windows is that I can't delete a file that another process has opened. This often leads to the situation that I can't delete a large directory structure because some unknown program has a file open in said directory. I don't care, just let me delete the directory please! Maybe it's not a "Unix" design, but something done by Linux. The concept that a program can continue using an already opened file while to others it's deleted is quite elegant.

This times 1000. Windows’s pessimistic file locking is why even trivial system updates require a reboot. Makes my blood boil every time.

Mostly because the people writing those updates don't update themselves (pun intended).

It is elegant until it happens to be an important file now lost forever on process shutdown, and yes it is pretty much UNIX.

A very basic attack vector, to yank files used by other processes and not take place in the traditional lock file dance.
