One small point, it *can* matter whether a file works on a single user
machine or not depending how it was copied from one to the other.  If a
transfer was performed with something like a USB memory stick that is
formatted using FAT or FAT32 then there should not be any problems as
ownership information is stripped when using those storage formats.
However, if the transfer was performed with an NTFS formatted memory
stick or if it was a network copy that can maintain NTFS attributes then
there will be a problem.

Windows stores ownership information internally as GUIDs which will be
unique across all machines assuming the user account was created
directly (not enterprise user management).  It doesn't matter whether
the machine is "single user" or "multi user", every locally created user
has a GUID that other machines won't know about.
