    I tried all means possible to open UAC, including the one you mention (from cmd.exe as administrator) and no success. I have a single user account, myself as administrator. There's also an "Administrator" account, but I have not tested trying opening UAC from there.

    If you are able to open just fine in the other account, then you could delete the old account and create yourself a new user account to use instead while signed in to the "Administrator" account.

    Since you don't have a restore point, you could either leave it as is for now and use the .reg files to set UAC with, or refresh Windows to fix it.

    Since a refresh will wipe my desktop apps I'd rather opt for a fresh windows install, but before doing that I'll wait a bit more with my system as is, maybe there's some other solution. What about a windows repair that will preserve my apps? Would that fix it? Also, what about restoring/extracting the UAC exe from the windows install disk, is that possible? I remember it was possible with XP Another option: registry cleaners?

    Yeah, you could give a repair install a try without losing anything.

    What about re-registering C:\Windows\system32\UserAccountControlSettings.dll ?

    regsvr32 C:\Windows\system32\UserAccountControlSettings.dll

    Also, the two files I have in C:\Windows\system32 are as follows:

    Code:
    08/22/2013  06:53 AM            72,704 UserAccountControlSettings.dll
    08/22/2013  07:10 AM           219,136 UserAccountControlSettings.exe
    What do yours look like?

    Hmmm, I just tried it and got the same error you did.

    One last thing to try:

    Open a Elevated Command Prompt.
    Type cd C:\Windows\system32 and press Enter.
    Type UserAccountControlSettings and press Enter.

    See if UAC opens now.
