.. when anaysing just installed application, ZSoft Uninstaller write down to log MRU type enteries deleted by Windows core ... after some time if you want to uninstall monitored application, and then uninstall using ZSoft Uninstaller the old MRU type enteries already deleted by the windows core are again recreated to the registry by ZSoft Uninstaller...
As MRU registry enteries may be freely cleaned by hand or some utility (for example MRU Blaster) it is not important that they are recreated once they are deleted ...exactly by recreating theese unnecessary enteries small fragments of mess are made to the registry hives ... so my suggestion is that it is best to put it by default to the ignore list... offcourse it is your decision ...
regards and respect
