Hello ladies and gentlmen,

I have encountered an extremely annoying problem. Yesterday, i signed in with my outlook mail into Windows feedback, just to try it. Everything was fine untill Windows changed the default Administrator (the one that was when launching Windows) with the new one (the one that i signed in with).
Changing the administrator back was impossible. Every time i try to run an app There is a popup "Do you want to let this program make changes to your computer?", there are 2 options: Yes and No. However, Windows requests me to type the password, but there is no place to type it in, and the option "Yes" is faded. Nor i can change any permission settings: the same message pops up again.

Any ideas? Help!
