Microsoft Releases Important Security Update For Windows 7

Microsoft has also released a new security update for Windows 7 on the monthly Patch Day in October. The regular support has already expired, now there is only the Extended Security Update (ESU).

Nothing is known about the changes in this update. Microsoft has launched a series of new updates for users of the old operating systems for general patch day on the second Tuesday of the month in October 2021. The updates are recommended to all users, as the vulnerabilities allow security functions to be circumvented, disclose information, and lead to elevation of authorizations.
