I just tried it (Windows 7-32, ~3G memory), and got

No doubt a copy of the original 16-bit program. So it's run in a
virtual 8086 machine, and so far as it knows, it's hosted by DOS on
one of those ancient processors. When I run mem on 64-bit WIn10, I
get:

'mem' is not recognized as an internal or external command,
operable program or batch file.

So they didn't even try to update it for the post-DOS world.

For interest: the version of mem.exe I have (it was I who did the above
trial run), under Windows 7 (32 bit), is in C:\Windows\System32 (and
somewhere in winsxs as well), is 39,274 bytes, and shows created,
modified, and accessed as 2009-7-13 22:40:56. No name, version number,
or many other such fields.
