No it does not. And it is not likely to do so either. It wouldn't be all that hard to add, but if something changes, what should be done upon uninstallation? Deleting it wouldn't be very wise, and it can't be replaced with the old file as ZU doesn't have that...
1) I would email the author of the program and ask why there was no mention of an OS file being replaced.
2) I backup my OS directory just in case a file crashes or something like the AVG Anti-virus false positive problem of last year occurs (AVG incorrectly recognized Winlogon.exe as a trojan, and either quarantined or deleted it, causing many of their users to be unable to boot up. They had to either boot to DOS and copy Winlogon.exe from a floppy or do a repair with their Windows disk).
This way I have a copy on a CD of all my
current OS files and can replace one in an emergency. I also use an imaging program that copies my OS/Program files partition.
That's why a file comparison by date and version number would be advantageous, in my opinion.
I think several of the Karen Kenworthy's Karenware Powertools freeware programs can do it. Her backup Replicator program copies file info and so does her directory printer program.
