For mintty this means you *can* extend its manifest if you like.  It
will avoid that PCA takes control of mintty.  Here's what works for me,
even on W7.  The GUIDs identify the operating system versions.  The
first one is for W7, the second one for Vista.  The GUID for W8 has not
been released yet, afaics.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
  <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
  <compatibility xmlns="urn:schemas-microsoft-com:compatibility.v1">
      <supportedOS Id="{35138b9a-5d96-4fbd-8e2d-a2440225f93a}"/>
      <supportedOS Id="{e2011457-1546-43c5-a5fe-008deee3d3f0}"/>
