</span>I'm not sure what kind of data Firefox analytics<br>
collect, but you could check if<br>
HKLM\SYSTEM\WPA\PosReady\<wbr>Installed == 1 in the<br>
registry. There were some other Windows Embedded<br>
keys as well, but I think those are defunct at<br>
this point. This is not necessarily foolproof as<br>
there are those who only tweak the registry for<br>
the duration of checking WU for updates, but most<br>
casual users likely wouldn't bother with that.<br>
<br>
It may turn out that I have an exaggerated idea<br>
about the size of this group relative to the<br>
overall XP population, but at least based on my<br>
own social circle and quite a few internet forums,<br>
this trick seems to be pretty well known and is<br>
used even by some very unexpected people (based on<br>
their geekiness factor).<br>
<br>
As an aside, I have to say that MS was in a way<br>
quite brilliant in how they convinced everyone<br>
that maintaining XP past its 2014 EOL date was an<br>
absolute no-can-do and making corporations pay for<br>
continued security patches, while at the same time<br>
knowing prefectly well that they'd have to keep<br>
maintaining the virtually identical POSReady<br>
version all the way until 2019. Like I said, there<br>
have been almost no reports of problems with using<br>
these updates on regular XP. IIRC there was one<br>
update that degraded font display, but even that<br>
had nothing to do with anything POSReady specific<br>
and got fixed pretty fast. That's an excellent<br>
track record compared to what's been happening<br>
with Win10 and even Win7 updates recently. So we<br>
have this odd situation where those with no<br>
particular reason to keep up with XP details think<br>
its "dead", "hihghly insecure" and whatnot, while<br>
those on XP can, if they so choose, still get<br>
almost the same level of support directly from MS.<br>
