STIG ID: WN22-CC-000450 | SRG: SRG-OS-000480-GPOS-00229 | Severity: Medium | CCI: CCI-000366 | Vulnerability ID: V-254376

Description

Windows can be configured to automatically sign the user back in after a Windows Update restart. Some protections are in place to help ensure this is done in a secure fashion; however, disabling this will prevent the caching of credentials for this purpose and also ensure the user is aware of the restart.
