HELP! Unable to install takeownership.reg UAC is turned off!

Im very new to all of this and I was following the instructions to a tutorial on how to change the sound that you hear at the login page and I needed to install takeownership for one of the steps. Unfortunately I have been unsuccessful with installing this. UAC is turned off... I am able to download it. Unzip it. But not able to install. Plz Help. Tell me what I am doing wrong or what steps Im missing or need to add.

Win7 Home Premium Service Pack 1 64bit OS

Unfortunately I am unable to find that tutorial link. I've been so caught up trying to install this takeownership program. I am logged in as administrator. If I remember correctly I needed to download three things in order to change my startup sound. Audacity, Resource Hacker, and Takeownership. So far I've successfully converted my sound file as .wav @299kb. As for the other steps I can't remember too frustrated with not being able to install takeownership. When I unzip takeownership and try to install I don't get an error msg but my notepad pops up and reads....

Code:

 
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\*\shell\runas]
@="Take Ownership"
"NoWorkingDirectory"=""
[HKEY_CLASSES_ROOT\*\shell\runas\command]
@="cmd.exe /c takeown /f \"%1\" && icacls \"%1\" /grant administrators:F"
"IsolatedCommand"="cmd.exe /c takeown /f \"%1\" && icacls \"%1\" /grant administrators:F"
[HKEY_CLASSES_ROOT\Directory\shell\runas]
@="Take Ownership"
"NoWorkingDirectory"=""
[HKEY_CLASSES_ROOT\Directory\shell\runas\command]
@="cmd.exe /c takeown /f \"%1\" /r /d y && icacls \"%1\" /grant administrators:F /t"
"IsolatedCommand"="cmd.exe /c takeown /f \"%1\" /r /d y && icacls \"%1\" /grant administrators:F /t"

here's the link How to change and replace the Startup Sound in Windows 7 - YouTube

I tried the take ownership short cut with the same outcome as b4, it did not instal and my notepad popped up with a similar msg if not the same as I had copied & pasted on here in my last post.

I also followed the steps in the tutorial that was recommended and I received this msg Access is denied. 0 files copied.

Question: In step 15 it states to move and save original imageres.dll to a safe location. I was able to do that. But what happens to the new imageres.dll file that was just created by resource hacker? Where should I place this file or should I just leave it on my desktop? I tried to place it back from its copied location but was denied access there as well.

<stupid question>

Since when does one have to hack a system file or take ownership of anything just to change the startup sound? Isn't that just a matter of editing the sound scheme through Control Panel?

</stupid question>

Yaaay I've finally successfully downloaded AND INSTALLED take ownership!!!!! Thank You BRINK for your time and patience. Sincerely thank you. That was the problem I was openning it with the wrong program. Okay but that was only part 1.

Still trying for part 2 of my problem. The main reason why I started to download audacity resource hacker and take ownership. I'll try this again a lil later. But thanx again BRINK!
