Permanent activation of UAC

[DenisC]

Hello,
I'm using CCleaner laptop version 5.38.6357 and I'm having a problem.
Indeed, CCleaner on the main Windows account works perfectly well with the parameter UAC = 1.

However when I run it from my 2nd UAC user account is disabled, I activate it and everything works fine.

But when I come back on the first account the UAC is deactivated again.
Is not it possible that the UAC remains active regardless of the open Windows session?
 

Thank you for your reply.
Denis
