Description of the uAInSessionHelper.exe Helper Process
Some information is only available to processes running in a user’s session, not to services running in session 0. In order to be able to collect such data, too, uberAgent makes use of the helper process uAInSessionHelper.exe
.
uAInSessionHelper is a lightweight and short-lived process that collects specific data, sends it to the main service and then exits.
How Often is uAInSessionHelper.exe Run?
uAInSessionHelper is run for the following reasons:
-
To collect information about a UWP app

Common Errors
Class Not Registered
You may see messages like the following in uAInSessionHelper’s log file:
2015-09-04 22:16:48.140 +0200, ERROR, HK, XA1$, 1856, IE Performance, Action 2 failed with: -2147221164
2015 - 09 - 04 22:16:48.142 +0200, ERROR, HK, XA1$, 1856, GetBrowserPerformanceIE, Failed (2) with: Class not registered
The root cause for these errors is that uberAgent can only determine IE performance per website if IE is run in desktop mode, i.e. not as a Citrix XenApp published application. If IE is run as a published application certain classes required by uAInSessionHelper are not available, thus the messages.
