In my case, it was in HKEY_CLASSES_ROOT\Appid\{86F80216-5DD6-4F43-953B-35EF40A35AEE}.
Under this key you have 3 values :
•The first one (default) with the value "CElevateWlanUi"
•The second one AccessPermission of type Reg_Binary with a binary value (does'nt matter to understand what it means)
•The third one is called DllSurrogate with a null value.


The way I solved the problem is to setup the authorizations of the main Key {86F80216-5DD6-4F43-953B-35EF40A35AEE} by a right-click, then "autorizations".
After you have to take possession of this key.
I setup the owner as our domain administrator.
For that click on the the button "Advanced" then on the tab "owner" and replace TrustedInstaller by the administrator of my domain.
Then, I came back to the main panel of authorizations of the main key.
I deleted the entry LAP505\administrators and the entry LAP505\domain users, and added the entry for my domain administrator with all rights. (LAP505 is the computer name)
I applied all the modifications.
I repeated the operation for the second occurence of the key :
HKEY_LOCAL_MACHINE\Software\classid\Appid\{86F80216-5DD6-4F43-953B-35EF40A35AEE}

And when I logged on with a user with local admin privileges, I could connect to WIFI network, I could access to the network center but I could'nt unmark the "Hide caracters". It works!"
