This is a regression.
Prior to 7u1, the AU UAC program name was changed from "jucheck.exe" to "Java Auto Updater". This allowed for a more recognizable/less scary file name/source of the UAC request. The program name has reverted back to (~7u3 and beyond), "jucheck.exe". See snapshots attached.

Here's just one user comment:
"jucheck" looks like a "junk" alert. Why not use the word "java" which would be more friendly??

Please change program name back to, "Java Auto Updater"
