I noticed the Edge Browser reference too, but the phrase "for the best protection" seemed a little unnerving as it suggetsts that M$ have known about it for a LLOONNGG time and it is a difficult thing to patch. Their record of continuous updates are renown many of which are race conditions but this one goes back a long way so much like our BREXIT exit will be a difficult one to cure due to its age and intertwined nature.
Just my opinion of course but nevertheless bringing it into the open will make Joe Public aware of it.
However, this is an equally dangerous bug like the Linux and Android ones posted recently.

ipsec_ranbits
IPSEC_RANBITS(8) [FIXME: manual] IPSEC_RANBITS(8)
NAME
ipsec_ranbits - generate random bits in ASCII form
SYNOPSIS
ipsec ranbits [--quick] [--continuous] [--bytes] nbits
DESCRIPTION
Ranbits obtains nbits (rounded up to the nearest byte) high-quality random bits from random(4), and emits them on standard output as an
ASCII string. The default output format is datatot(3) h format: lowercase hexadecimal with a 0x prefix and an underscore every 32 bits.
The --quick option produces quick-and-dirty random bits: instead of using the high-quality random bits from /dev/random, which may take
some time to supply the necessary bits if nbits is large, ranbits uses /dev/urandom, which yields prompt results but lower-quality
randomness.
The --continuous option uses datatot(3) x output format, like h but without the underscores.
The --bytes option causes nbits to be interpreted as a byte count rather than a bit count.
FILES
/dev/random, /dev/urandom
SEE ALSO
ipsec_datatot(3), random(4)
HISTORY
Written for the Linux FreeS/WAN project <http://www.freeswan.org> by Henry Spencer.
BUGS
There is an internal limit on nbits, currently 20000.
Without --quick, ranbits's run time is difficult to predict. A request for a large number of bits, at a time when the system's entropy pool
is low on randomness, may take quite a while to satisfy.
Though not a bug of ranbits, the direct use of /dev/hw_random, the Linux hardware random number generator is not supported because it can
produce very non-random data. To properly use /dev/hw_random, the rngd daemon should be used to read from /dev/hw_random and write to
/dev/random, while performing a FIPS test on the hardware random read. No changes to Openswan are required for this support - just a
running rngd.
