12 Administrator Guide for SAS 9.1.3 Foundation for Microsoft Windows
If the system meets the minimum system requirements, the wizard will display a message to
that effect, and will not perform any updates.
If updates are required, one or more reboots may also be necessary to update components
that are in use by the operating system. Unfortunately, rebooting the system is the only
reliable way to release these in-use files for updating.
To minimize user interaction during reboots, the System Requirements Wizard supports Auto
Logon. Auto Logon temporarily stores a valid User ID and Password in the Windows Registry
during reboots. This User ID and Password combination is used to automatically log on to the
system between any required reboots, and is cleared from the registry after each logon. As the
wizard requires additional reboots, the combination is used again. After the final reboot, the
User ID and Password are no longer present in the Windows Registry. (For more
information on Auto Logon, refer to Microsoft Knowledge Base Articles #Q310584, #Q97597,
and #Q234572.)
In order for Auto Logon to function properly, your PC must not have a hardware password
enabled. A hardware password would prevent the reboots that may be necessary for a
successful update of your system components.
The System Requirements Wizard will prompt for your Automatic Logon credentials.
