over the years I've had the same phenomenon with various versions of msysgit
(now at 1.9.5.msysgit.0, on Windows 7 64bit), so I'm now sufficiently
confident of it being a long-standing, longer-term issue and thus I'm
reporting it now.

Good idea.

Since I'm doing development in a sufficiently rebase-heavy manner,
I seem to aggregate a lot of objects.
Thus, when fetching content I'm sufficiently frequently greeted with
a git gc run.
This, however, does not work fully reliably:

    Auto packing the repository for optimum performance. You may also
    run "git gc" manually. See "git help gc" for more information.
    Counting objects: 206527, done.
    Delta compression using up to 4 threads.
    Compressing objects: 100% (27430/27430), done.
    Writing objects: 100% (206527/206527), done.

A workable workaround for this recurring issue
(such a fetch will fail repeatedly,
thereby hampering my ability to update properly)
is to manually do a "git gc --auto"
prior to the fetch (which will then succeed).

I've never had this issue. The error message from unlinking the file
means that someone is still accessing the file and thus it can not be
deleted (due to the implicit file locking on windows).

Best guess is that an antivirus is still accessing it. There is a tool called `WhoUses.exe` in msysGit (I do not remember if I included it into Git for Windows 1.x for end users) which could be used to figure out which process accesses a given file still: https://github.com/msysgit/msysgit/blob/master/mingw/bin/WhoUses.exe (maybe that would help you identify the cause of the problem).

Ciao,
Johannes
