Hello,
I'm annoyed by the following problem:
- Everything (see http://www.voidtools.com/) apparently requires to run as an
administrator on Windows Vista, 7 and 8 -- I did not have any problem at all
under Windows XP
- Emacs can't communicate with it (to display the locate results, in Helm, for
example) if it's not running as well as an administrator...
So, for the last few days, I'm running both programs as an administrator.
But that brings the following big inconvenients:
- I need to confirm, at every launch of Emacs, that I'm OK for it to run as an
admin (User Account Control, UAC prompt)
- Files created under Emacs are now owned, by default, by "Adminstrators"
- When Emacs crashes, GDB can't connect to the process -- unless, I guess, if
my terminal is running as well as an adminstrator
- and so on...
I guess I'm not the only one using Emacs and Everything on a recent Windows
platform. How did you solve this dilemna?
Best regards,
Seb

The Emacs annoyances you describe are directly caused by trying to adapt Emacs to the deficiencies of non-Free software. Perhaps try another tool, such as GNU locate, which does not suffer such problems.

I doubt it's related to the fact that Everything is not open (well free
regarding the price).
Another tool such as locate could certainly work, though it's not
straightforward to set up under Cygwin, and locate's contents is only updated
every once in a while.
Everything, on the other hand, is always fully up-to-date. You move a file, it
already knows about that. Very practical.
Best regards,
Seb

I would try to setup an Windows batch file (.cmd) and call the "runas"
executable specifying a different user. With a little bit of tweaking you
should be able to make this work without entering your password very often
and by keeping the environment of your user.
Even though Voidtools runs as Administrator, it should run your Emacs (or
any other program) under a more restrictive account. My suggestion should
help you to accomplish that. This is really a question for their support
site...

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.

Under XP, the first user created during setup is automatically an
administrator unless you take specific steps to avoid it.

You could write (or have someone (possibly the developer of
Everything) write for you) an intermediate program that would start as
administrator, interact with Everything, and provide a programmatic
interface over some form of interprocess communication to low
privilege users. (Ideally, it would have to check the access rights of
the connecting user against the access lists of the directories the
user is trying to search.) You might be able to tweak the ES
commandline client, or borrow some of its code, to do that.
That said, Everything seems to be a very ugly piece of software, even
for a Windows program, from an architectural point of view. (It should
have its service part split off of the GUI part, and it should not
contain an implementation of a server for an extension of the FTP
protocol.)

Update on this. Very hot. Everything's latest (beta) version of 10 January...
2013 [1] does solve the problem I had: Everything is now working without
requiring to "run as an administrator". So does run Emacs now, while getting
back the functionality I was striving for.
Problem is solved. Case closed.
Thanks for your help.
Best regards,
Seb
[1] There have been a couple of changes since December 2012, after more than 2
years with no activity at all. I don't know which beta version does solve the
problem, but the very latest does.
