Enable the Windows built-in local Administrator account and set a password. Also, hide the account from Login Screen, using the registry.

net user administrator /active:yes
net user administrator YourPasswordHere
reg add "HKEY_Local_Machine\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList" /v Administrator /t REG_DWORD /d 0 /f
exit 0;

 

after running this script... How can i log in remotely with admin rights?

Hey @VulperiaStefan form Pulseway here, thanks for your message. 

Once you have ran the script as well as installed the Pulseway agent on you PC, you should then be able to login remotely via the remote control section on your sidebar. Here you also have options between a shared or MS RDP. 

I hope this helps and if you have any other questions, please ask away.
