What is AiM?
AiM is Auto ini Mod.
It does what it says on the tin. Mod some ini settings automatically!
I recommend Skyrim configurator by pfannkuchen_gesicht to fully edit you Skyrim configuration. He added (after my suggestion) the three options for us, which now makes his Configurator my preferred utility. Still you can use AiM if you only want the three options set.

Messages: Please read all the description. While the ReadMe is basically the same, I will update here. So read down. >>> Read past this section, if you just want to know more...
> If you use a mod manager such as NMM, rearranging your mod load ordering with Skyrim Launcher Data Files will forfeit the benefit of the handy BOSS masterlist, if you run Skyrim from the Launcher directly without NMM. If you happen to rearrange with the Launcher, start NMM and shuffle a mod up and down in the list. Do any rearranging in your Mod Manager. NMM will keep mod priority intact, you cant move a mod down if it requires top loading. I found that JaySuS Swords is kept at top of order as requested by BOSS masterlist. So, NMM doesn't need a re-sort option. Just remember to load Skyrim with NMM or shuffle like I mentioned above.

What settings?
Automatically;
Enable 'Data Files' option in Skyrim Launcher.
Enable Print Screen (Prt Scr) Key for 'Screenshots'.
Disable Bethesda 'Intro Video'.

So, briefly, hows it work?
v1.03, automatically in order:
1) Run a few checks, such as, see if Skyrim folder and ini files are available.
2) Backup your ini files for you automatically. Two sets of backups.
3) Give you the option to abort the operation and exit.
4) Wipes any of the set variables and their lines we are replacing.
^ Into a temp text file we make the changes.
5) Check that the [Sections] exist in the ini files.
^ They should, but if they don't we will add them at end of file.
6) Adds the variables within the correct [Section] and setting.
^ Now all should be intact, we replace the ini with the temp. Job done, have a beer :)

How do I install this?
Just extract the files somewhere (Desktop,C:\,G:\String Nice) and run "Auto_ini_Mod.bat".
If you run it from a location other than Windows Homedrive (C:\), Run as Admin.
BTW, AiM is made for Windows 7. May or may not work on Windows XP.

Backups:
Well AiM makes two sets of backups at the very beginning before any changes.
Skyrim.ini.orig_bak is a first run backup. It never gets replaced unless you rename or delete it.
Skyrim.ini.mod_bak is updated everytime you run AiM.
To Restore a Backup:
A) Use "Auto_ini_Mod_Backup_Restore.bat" OR...
1) Browse to your My Doc\My Games\Skyrim folder.
2) Delete Skyrim.ini file to be restored.
3) Rename Skyrim.ini.orig_bak to Skyrim.ini
Note: If you want to run "Auto_ini_Mod_Backup_Restore.bat" from a storage device other than your Windows Homedrive (C:\), Run as Admin.

Changes:
v1.03 Added support for running from location other than Windows Homedrive (C:\).
Refined the checking of directories to include notification when Admin is needed.
Also added the location check to Backup Restore.
Spaced text in a little for display.
Any directory structure and location will now work. Run from "G:\String Red Hot", my favourite =)
v1.02 Fixed the whole directory with spaces problem for sure this time.
added "Auto_ini_Mod_Backup_Restore.bat".
v1.01 Fixed a problem when AiM's directory included spaces. Sorry about that.
v1.00 Initial release.
