Existem alguns tópicos em answer.microsoft.com onde os engenheiros da Microsoft confirme que esta é realmente uma credencial criada pelos produtos da Microsoft:
Credenciais genéricas desconhecidas no windows 7 - virtualapp / didlogical
Um funcionário da Microsoft chamado Divya R diz:
Virtualapp/Didlogical is a credential that is stored when you use any of the Windows Live products, this can include Windows Live Messenger, Windows Live Mail, Windows Live Sign-In Assisstant, Windows XP Mode and other Microsoft services.
You may delete the entry from the Credential Manager.
como o virtualapp / didlogical chegou às minhas credenciais genéricas do Windows 8 em meu computador desktop e isso afeta o acesso à Internet?
Um funcionário da Microsoft chamado Tadasha Mishra diz:
The entry Virtualapp/Didlogical is a credential that is created when you use any of the Windows Live applications and other Microsoft services.
Sob credenciais genéricas eu estou recebendo VIRTUALAPP / DIDLOGICAL (mas em letras minúsculas) eu apague mas retorna mais tarde. Como faço para me livrar dele permanentemente?

Também há casos em que os produtos da Microsoft apresentam um mau funcionamento porque essa credencial estava incorreto.
Por exemplo, no OneNote 2010 não sincronizado com a correção do SkyDrive :
Since the recent IE fix I’ve had an issue with OneNote 2010 not syncing with OneDrive (formally SkyDrive). It would say I needed a password to connect and when I would try to sign in it would come back with: “We can’t sign you in because the network isn’t available. Make sure your computer is connected to the Internet and try again.”
Since the failure occurred when trying to sign into Windows Live, decided it might be an issue with the Windows Live ID credential store by Windows – turns out I was right. By deleting the stored credentials I was able to get OneNote syncing again.
Um bom resumo deste assunto pode ser encontrado no artigo O que é Virtualapp / Didlogical? :
Virtualapp/Didlogical is a credential that is stored when you use any of the Windows Live products, this can include Windows Live Messenger, Windows Live Mail, Windows Live Sign-In Assisstant, Windows XP Mode and other Microsoft services.
In general it is safe to delete it – however, it’s pretty useless to remove it IF you are using Windows Live or any other Microsoft services on a regular basis. I would therefore not recommend to delete it.
If you continue to use the Microsoft Windows Live products, you will always have this entry. The only solutions is to uninstall Windows Live products and look for alternatives, but since this is not a security problem there is absolutely no reason to do that.
