[tex-live] Install-TL hanging at TeXlive.infra.win32

[Philip TAYLOR]

The problem has now disappeared.  I removed
all non-essentials from the taskbar notification
area (and hence stopped them running), ran SysInternals
"Filemon" to watch the installation drive in
the hopes of being able to identify the cause
of the hang, and repeated the installation.
On this occasion it got past TeXlive.infra.win32
with no apparent difficulty, although I see from
the log (below) that it was unable to "unlink" it.
