User account control

User Account Control (UAC) is a Windows security feature that helps prevent malware from compromising the operating system. UAC restricts programs to standard user privileges.

When UAC is enabled, programs that require elevated privileges cannot run without your permission.

The backup-archive client requires elevated privileges. If UAC is enabled when you run the client, a User Account Control dialog box is displayed. The dialog asks if you want to allow the program to run. If you are not logged in as an administrator, the dialog also asks for your account credentials.
