The Win 10 patch is still uploaded, but it's actually a goodbye patch. 🖤

Microsoft released a security update (Patch Tuesday) for October 2025 for Windows 11, code KB5066835 and KB5066793, the last round in which Windows 10 will receive a free update, after the official supply phase expires this month.

.

In this round, a total of 172 vulnerabilities were fixed, including six Zero-Day vulnerabilities that were made public and actually compromised in some cases.

.

There are a total of 8 Critical vulnerabilities, divided into Remote Code Execution - RCE: 5, and Elevation of Privilege: 3.

.

A breakdown of the vulnerabilities that have been addressed is as follows:

- Elevation of Privilege vulnerability: 80 items

- Security Feature Bypass vulnerability: 11 items

- Remote Code Execution Vulnerability: 31 items

- Information Disclosure: 28 items

- Denial of Service vulnerability: 11 items

.

These figures do not include vulnerabilities that were addressed earlier in the same month; such as Azure, Mariner, Microsoft Edge and other Microsoft services.

.

In addition, Microsoft officially announced the end of Windows 10 support. Users can apply for Extended Security Updates (ESU) to receive security updates for 1 year. The enterprise segment can be extended for up to 3 years.

.

In addition to Microsoft, there are other software manufacturers that release security updates during the same period, such as Adobe, Cisco, Draytek, Gladinet, Ivanti, Oracle, Redis, SAP, and Synacor.
