You’re missing the key that Kali uses to sign their packages. You can use gpg to download the key and apt-key add to add it:

 gpg --keyserver pgpkeys.mit.edu --recv-key ED444FF07D8D0BF6
 gpg -a --export ED444FF07D8D0BF6 | sudo apt-key add -

Run applications as administrator by default in Windows 10

If a search lead you here, and you want to always run a specific application as administrator even when launching its associated file type, you have to use the registry. Those compatibility tabs on properties are no longer available in windows 10.

Create a new registry key in one of these existing keys,
for current account only:

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

for all users:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

Create a new key, the name of the new key should be the path to the application you want to always launch elevated, the value of this key should be
~ RUNASADMIN
