How can I verify that a Windows XP POS operating system executable is authentic?

digital-signature windows-xp-embedded

Windows XP Embedded POSReady is now on extended support until April 9, 2019. This means no new features and fewer bug fixes and patches. It is entirely possible that this update was legitimate, but is better checked. It is also possible that the firewall detected just now a change that happened some time in the past.

Possible checks:

  • Verify the history in Windows Update,
  • Run sfc /scannow to check system integrity.

Reboot the device before starting, just in case.
