02/17/2026, 7:30 PMOkay, who has dealt with API hook exclusions recently? Working through an issue right now, and we're configuring our one our apps using the ExcludedImageNames registry key (applied via GPO). Citrix used to have a document outlining the various methods for this, and I swear one of them was also the UviProcessExcludes registry key, but now I cannot find that article.

02/17/2026, 8:22 PMYeah, we have been using ExcludedImageNames, as well, but have also been asked recently to try UviProcessExcludes for other things. This is the only article I could find showing the two, and it's not clear which one should be used for newer VDAs: https://web.archive.org/web/2/https://support.citrix.com/support-home/kbsearch/article?articleNumber=CTX107825

02/17/2026, 8:55 PMYep, I'm aware of the 14-character limit. I wrote a script years ago to append this stuff with that in mind.
