When does the Operating system verify the Authenticode Signatures for signed EXEs and signed DLLs?

When PE Files (exes, dlls etc.) are code signed using signtool, they can be verified to check if they have been authored by trusted publishers. In which scenarios does the Operating system actually verify signed EXEs and DLLs?

1. Are signatures of EXEs verified every time they are run?
2. If an EXE has a dynamically linked DLL, is the DLL's signature verified when the EXE is run?
   
3. If the EXE dynamically loads a DLL using LoadLibrary, is the DLL's signature verified when the EXE is run?
4. When an EXE requires elevated privilege (UAC), is the signature of the EXE and the DLL dependencies verified as well? (1-3)

If this questions belongs in a different category or community, please let me know. Thanks.

1. In normal mode open an administrator command prompt and enter the below command
2. In safe mode open an administrator command prompt and enter the below command

The two-step verification emails show up in my inbox but I added a rule to mark the domain name safe a long time ago (verified that "techpowerup.com" is still in the safe sender list).
