It appears that UAC is broken

cant move/delete some file/folders, when asked to use administrative right (and say yes) it shows the loading bar and then nothings gets moved/deleted, no error whatsoever

opened control panel, user account and when i click on any option with the Shield (administrative rights) the mouse changes to loading and thengo back to normal, not opening any menu or showing any error

1. Already done a sfc /scannow , no errors found
2. Already used Microsoft's Fix it, reclycle bin broken and repaired, still the same error
3. Used microsoftaccounts tool , this are the errors i got:
   
   • Problem with microsoft account policy... <- this is the problem (didint fix)
   • Trust this PC <- loop of redirections, cant get to trust this pc (only one with w8)
   • Problems witht sytem registration : i think it is because of the soft system reset
   • Some setting have sync turned off : i never configured anything to sync
   • Rootcauses found and created logs : would like to know where the logs are saved...
4. had to use a ".reg" file to change uac setting to never notify, thinking it would fix this, no, it stoped asking though, i can still open a cmd with Administrative rights, but cant access to UAC settings
5. Accesed Administrator account (net user administrator /active:yes)and even with that account could change any settings

so there it is, dont know what else to do in the moment (this pc broke with 8.1 update and was restored to factory configuration, it broke several drivers and kept most of the registry entries, i cant find the cause of this problem.

other info: i tried to delete a file in a program folder and couldnt, downloaded unlocker to check first if it was permissions but no, it showed me a msg telling me that there wasnt any error, and if i would like to delete it, clicked on yes, and it did delete it, what amuses me is that i cant without this tool, not even using the feature that takes over ownership

Edit: wow, in a not crappy pc chkdsk is fast, completed with no errors found : /
