These failures only happen on the cw-gtx560 and cw-rx460 Windows 8.1 machines.
I suspect this is because these have more recent Windows updates than the
TestBot's w8 and w864 machines (see bug 52858). More specifically cw-rx460 has
had more recent updates than cw-gtx560 for quite some time and I further
updated both on 2022-05-02.

I further plan to update the TestBot's VM (the rationale being that Windows 8.1
is old and we really only care about the latest version) which should make it
easier to debug. In the meantime this does seem like a regression.
