Almost all users Windows γνωρίζουν την εφαρμογή “Windows Update” μια υπηρεσία ενσωματωμένη στο λειτουργικό τους, που βοηθάει στη λήψη και εγκατάσταση των τελευταίων ενημερώσεων, service pack, drivers και των κρίσιμων επιδιορθώσεων που κυκλοφορεί η Microsoft.

So they are unable to download or install new updates, there are messages from random errors, or the application is unable to look for new updates, and when searching it can search for years.
