MS13-054-Windows6.1-KB2834886-x64.msu is showing ‘Installed by User’ in the client GUI; however, the update is not listed in the client’s Add/Remove Programs as installed.
Found the rule is working appropriately for IsInstalled; however, if an issue occurs during installation, the update can implement the updated .dll, yet the update fails to completely install.
Added source code change to the rule to add secondary checks for IsInstalled=TRUE.
