Microsoft is releasing seven bulletins (five ‘critical’, two ‘important’) to address a total of 12 vulnerabilities. The critical bulletins address 10 of the vulnerabilities in Microsoft Windows, Microsoft Office, Internet Explorer, and Microsoft Server Software. The important bulletins address the remaining two vulnerabilities in Windows.
Remember to close all applications at the end of work day today because several updates require a reboot to complete installation.
