Although Windows 7 system has long stopped supporting, Microsoft still provides security updates for devices that join the ESU program In other words, your Windows 7 device won't get any patches unless your company pays for security updates.
This month, support ESU program windows 7 users get the monthly update summary of kb5014012. In addition to fixing the recently exposed security vulnerabilities, three non security fixes have been introduced:
● fix that the key distribution center (KDC) code incorrectly returns an error message during domain controller shutdown_ ERR_ TGT_ REVOKED
● after installing the windows update and subsequent updates in January 2022 on the primary domain controller simulator (pdce), use netdom Exe or "active directory domains and trusts" snapshot, listing or modifying the route of the name suffix may fail, and you will receive the following error message: "insufficient system resources exist to complete the requested service".
● when attempting to scan outward only trusts, the primary domain controller (PDC) of the root domain incorrectly records warning and error events in the system log.
Since reaching the support period in January 2020, the market share of Windows 7 has obviously decreased significantly, and the operating system is now in the third and final year of ESU plan. In other words, from 2023, even paid updates will not be shipped, so customers have no choice but to upgrade to a newer version of windows.
