GETTING RID OF TRUSTED INSTALLER DELETING FROM REGISTRY

Question

I tried to answer to another thread with a similar title and it has been locked..I wonder why? Of course not is obvious,Microsoft is peeved off.
The post started with this :
Has ANYBODY found an effective and easy-to-understand way to disable (decapitate, exterminate, disembowel) windows 7 'TrustedInstaller'?? This has to be, by FAR, one of the WORST devices MS has ever come up with. I wouldn't even be aware of it's existence,
if it had not been for it turning my OS processing into peanut butter sludge on so many occasions. And now, it appears to be interfering with adding legitimate 3rd party procedures and add-ons. It is a gargantuan CPU SUCK, and it doesn't appear to accomplish
ANYTHING that couldn't be accomplished w/ a combination of Win DEFENDER and UAC permissions. I did hear somebody comment, on another forum, that it "protects your system from making damaging changes to itself....blah, blah". Well, a howitzer will probably
be effective at killing flies, too, but is that the approach you want to take? What bothers me is that the PINHEAD who came up with this one, is probably kicking it in a plush MS office right now, and WORSE YET, will probably be making FUTURE decisions on
OS's. (Yeah, just when you thought the fun was over....)
This 'trusted installer' is a disease, and it is about time that Microsoft DID THE RIGHT THING by their customers and came up with an appropriate fix! But while we are waiting for Microsoft to do the right thing (I'm sure there's no hurry there....!) Is there
ANY way to terminate this process?? And I mean 'terminate...with EXTREME prejudice'.
Gratitude in advance to anyone who can help
 ( By someone calling themselves smccfly007)
I TOTALLY AGREE with this person.
Now I want to ask,what would happen if I delete trusted installer.exe from the registry? Would I automatically gain access to the programs this thing takes control of?
I mean it is stopping me from moving Notepad to my desktop,for years I had windows vista and I have always had  the notepad on my desktop....if I try to put a shortcut of Notepad on the desktop is telling me that I need permission from trusted installer.YOU
GOTTA BE FREAKING KIDDING ME!!!!!!!!!!!!  This is just another feature of freaking BigBrother is Watching you!
It annoys me that some clever big wigs think adding this features is clever or of any use....another symptom of why this world is upside down.
SERIOUSLY if anyone at all can provide me with a real solution to this please come forward,I ain't a computing expert so need step by step explanation but.......I want rid of this freaking virus.
Like mr 007 which post I pasted above any help will be greatly appreciated.
By the way I am a lady.

Answer 1

So apparently you did not read the post very well. Trusted installer is stupid at best. Before windows 7 this was not a thing and computers all over the world did not end....... I do not have a tried an true way cutting out this tumor that is keeping from
deleting things like background pictures how ever here are the steps to taking control over the stupid thing. It sucks I know but better slow than windows getting to do what it wants.
1. Go to the folder that contains the file or Folder whose ownership you want to change.
2. Right Click of mouse on that file or Folder and Choose “Properties“.
3. Navigate to “Security”
tab.
4. Click on “Advanced” on
the Security tab to open the Advance security setting for the file.
5. On the Owner ; Click on “Change“.
6. Click on “Advanced” on
the open “Select User or Group” Window.
7. Click on “Find Now” on
the open Window.
8. It will show you all the available user on the Search results.
9. Now select the user that you want to give the ownership and click on “OK“.
10. Again Click on “OK” on
the “Select User or Group” to change the ownership.
11. Now the Ownership for that file or folder is changed.
12. Now apply all the changes and Click on OK and close all the open Window.
13. That is it.
Again I am sorry it is only a treatment not a cure. 
BTW if you are going tell us about what its purpose is WE DON'T CARE. we lived fine without it before and now it is just causing stupid problems. 
I will keep looking and let you know what i come up with.
