If you notice your computer is running slow, or you can't communicate from Datamakers to your register (specifically Verifone sites, please do the following to check your PC for these critical updates.
1) In the lower left corner/Cortana search box type "updates"
2) If it looks like "you're up to date" look a little bit further down and you might notice a "download and install" link.
3) Click on this and let that finish downloading AND installing. Be patient as it may take 5 - 10 minutes. It will prompt you to "Restart now" when it is finished.
Restart your computer.
Repeat this process after the restart, once more, because it pushes updates down sequentially.
