When I try to do anything that needs elevated privileges in Windows 10 (such as run a program downloaded from Internet), I get the question
Do you want to allow this app to make changes to your PC?
but it has no yes option, only no button. This happened after I changed my account's type to user (it was administrator). However, for whatever reason, the laptop seems not to have any other administrator account, or it is not enabled. Commands like
net user administrator /active:yes
show the same dialog, without a yes button.
I tried substituting SETHC.EXE with CMD.EXE as this question recommends, and five times pressing Shift really brings a command prompt, but it does not have admin rights: it runs under the same user account.
Anything else I can try?
