No, unfortunately that is where I expected to find it, but it does not appear there if caRepeater was started by another EPICS application.  It did appear in the Processes tab in Windows 7, but does not appear in the Details tab in Windows 10.

Hi Mark,

I believe that the other option to find this process in the Windows 10
Task Manager is under the 'Details' tab (which to me looks like the
Windows 7 'Processes' tab) .

Best regards,

Žiga

If an EPICS client or IOC is run on Windows it will launch a caRepeater process that runs in the background.  If you want to update your EPICS installation you must kill that caRepeater process before you can do so.
