when i try to start up my computer i get this error "a problem is preventing windows from accurately checking the license" i don't know what could have caused this. i tried searching up google to find answers and 1 article said to delete a registry in " HKEY_USERS\.DEFAULT\Software\Microsoft\Cryptography\Providers
HKEY_USERS\S-1-5-20\Software\Microsoft\Cryptography\Providers"
i get up to microsoft but after that i cant find "Cryptography". any help would be very appriciated, thanks.
