There is a native Windows port here:

  
http://sourceforge.net/projects/ezwinports/files/findutils-4.2.30-4-w32-bin.zip/download

although I never tried this on Windows 8, so caveat emptor.  I do use
this on Windows 7, and there are even 64-bit (as well as 32-bit)
binaries in the pack, which should be significantly faster on a 64-bit
OS.

You could set up a scheduled task that will run every hour, if you
really need the DB to be so up-to-date.  (I have such a task run once
a week, and I never had any problems with files I couldn't find.)

If this is more important to you than get rid of the UAC prompts, then
you are already set up.

In any case, the list of measures I know of that might help you not to
get into trouble with UAC is:

  . Never run "as administrator", except for very rare and specific
    jobs.  Windows treats such users inherently dangerous and will pop
    up UAC prompts where it doesn't for other users.

  . If you possibly can, don't use a user who is "local admin";
    instead, use a "normal" user and grant that user all the necessary
    privileges via the Local Security Policy.

  . Take ownership on the entire hierarchy under C:\Users\YOUR-USERNAME;
    that will fix the ownership problems that Emacs might not like,
    because it doesn't always know that ownership by "Administrators"
    group is OK when the user FOO is a local admin.

  . Take ownership on any directory tree where you happen to work a
    lot, if that tree is not owned by you.

  . If you must run programs that write into C:\Program Files, take
    ownership on that directory and its subdirectories as well.

  . Some utilities might need a manifest where you tell Windows to run
    them at "asInvoker" level, to avoid the UAC prompts, because
    Windows in its infinite wisdom considers certain program names and
    even certain symbols inside them as evidence that the program
    might be "dangerous".  One example is the GNU Patch utility, but
    the exact rules by which Windows decides whether a program belongs
    to the dangerous lot are unpublished, so any program which pops up
    the UAC prompts should have a manifest created for it, before you
    conclude that it's something in the program's code that triggers
    that.

Not sure this will help you; I don't use Everything.  You may wish to
try Findutils anyway before you embark on the above adventure, who
knows, you might even like it.
