This example is based on Mercurial used up against development of websites on IIS 7.5
In the example, the repositories will copy and add new files between a repositories according web-folder and it's location on IIS, which also is the safest option.

When you work with Mercurial and in addition got the need to update your IIS 7.5 development files, here is how you can do it with ease.
The scripts will stop a sites AppPool and the website itself, run the Mercurial commands and start the AppPool and website up again.
Which means that the developer always sees the updated site when checking it with a web-browser.
There is some logging added as well.

Locate the websites repositories .hg folder and create/edit the file named hgrc (Remember to adjust the account name and paths)

hgrc

[ui]
; editor used to enter commit logs, etc. Most text editors will work.
editor = notepad
username = administrator@contoso.com

[paths]
default = D:\Repositories\Contoso\

[hooks]
commit = D:\Repositories\Contoso\.hg\HgPost_COMMIT.cmd
push = D:\Repositories\Contoso\.hg\HgPost_PUSH.cmd
changegroup = D:\Repositories\Contoso\.hg\HgPost_CHANGE.cmd

Now add following bat files (Remember to adjust the account name and paths)

HgPost_COMMIT.cmd

CALL "%~dp0HgPost.cmd" commit %* >> C:\inetpub\logs\hg\post.log 2>&1

HgPost_PUSH.cmd

CALL "%~dp0HgPost.cmd" push %* >> C:\inetpub\logs\hg\post.log 2>&1

HgPost_CHANGE.cmd

CALL "%~dp0HgPost.cmd" change %* >> C:\inetpub\logs\hg\post.log 2>&1

HgPull.cmd

@C:\Python26\Scripts\hg pull

HgUpdate.cmd

@C:\Python26\Scripts\hg update -C

HgPost.cmd

@ECHO off

@SET _roboString=%WebDir% %IIS_Dir% %_what% %_options% %_log%

@IF NOT EXIST %RepoDir% (
    @ECHO Error: %RepoDir% is not available
    GOTO :eof )

@IF [%1] EQU [commit] SET HgCommand=COMMIT
@IF [%1] EQU [change] SET HgCommand=CHANGE
@IF [%1] EQU [push] SET HgCommand=PUSH

@ECHO HG %HgCommand% for %RepoMap% executed %DATE% %TIME%
@ECHO.
@SETLOCAL

@ECHO _____________________________________________

@CALL %RepoDir%\.hg\HgUpdate.cmd
@ECHO.
@ECHO _____________________________________________
@IF EXIST %IIS_DIR% (
    IF EXIST %WebDir% (
       @ECHO Stopping %RepoMap% on IIS
       @ECHO.
       @RUNAS /user %UserName% C:\Windows\system32\inetsrv\AppCmd Stop Site %RepoMap%
       @RUNAS /user %UserName% C:\Windows\system32\inetsrv\AppCmd Stop Apppool %RepoMap%

    ) ELSE (
    @ECHO Warning: The repository does not exist as a website. )
    )
@ECHO.
@ENDLOCAL
GOTO :eof

EXIT

In addition to the above, we want some log management added, for that we create another bat file and add it on a task schedule. (Remember to adjust the path)

archive_hg_logs-cmd

ECHO

:DATE
IF NOT EXIST C:\inetpub\logs\hg\post.log GOTO :CLEANUP
MOVE C:\inetpub\logs\hg\post.log C:\inetpub\logs\hg\post_%date:~0,2%%date:~3,2%%date:~6,4%.log

:CLEANUP
IF NOT EXIST C:\inetpub\logs\hg\*.log GOTO :EXIT

::Delete logs older than 3 weeks
FORFILES /P C:\inetpub\logs\hg\ /S /M *.log /D -21 /C "CMD /c DEL @PATH"

:EXIT
EXIT

My task schedule looks like this in XML

TaskSchedule.XML

That's all there is to it.
