I have a key for '..RX Pro' written down somewhere that I've not yet tried,
and should have installed long ago!
Considering the many updates for Windows, if your Rollback Rx Pro functions as it should,
my gut feeling would be to ride this one out "as is" for as long as you can.
$19 + another 10 doesn't break the bank, yet unless it's time to abandon ship
(when Rollbck Rx Pro no longer "floats",:notworthy: so to speak) there should be no need to jump overboard for it's newer model. They should offer their patrons a special deal to upgrade, IMHO...
This is also how I have satisfied myself running the older version of Shadow Defender which Windows does not permit updating (as far as I know, on the Home Version) unless, or course, I upgrade to Windows Pro or it (the software program) becomes available in the Microsoft Windows Store!
