Microsoft has updated older operating systems as part of its “Tuesday Patches”. Published patches fix some problems in Windows 7 and Windows 8.1, while at the same time bringing security improvements.
Software giant Microsoft still offers extended Windows 7 support for enterprise users for a fee. Companies can receive security updates by January 2023 under the Windows 7 ESU program.
By 2021, the price of the ESU, i.e. Extended Security Updates service, has increased to $50 per computer. In 2022, it will go up to $100 per computer.
The company has released a Windows 7 update number kb5003233 for ESU users only. The patch solves an issue with the SMB protocol while at the same time making some improvements to the security system.
The software giant also released an update to another legacy operating system, Windows 8.1, kb5003209. This patch contains the same security improvements as KB5003233.
