- Windows 10 has received the latest security update
- It patches 172 OS security vulnerabilities, including six zero-day vulnerabilities.
- It's a sobering thought to imagine how these security holes will accumulate over the months for those who don't sign up for extended support.
Windows 10 has received the latest update – at least as far as official support is concerned – and it's somewhat of an eye-opener to the dangers you may face if you continue to use operating system beyond his End of Life.
Bleeping Computer Reports that the October 2025 update contains many fixes to security issues in Windows 10.
In fact, this latest cumulative update for Windows 10 contains fixes for 172 security flaws, including six zero-day vulnerabilities.
A zero day vulnerability This is a security hole in Windows 10 that Microsoft did not know when the attack vector appeared and was made public. The name refers to the fact that Microsoft did not have days to respond to the threat (in other words, it was not detected by the developer and patched in advance – which is ideal).
So, these are troubling flaws – as attackers may try to exploit them given their unpatched nature – and fixes for them are included in this October update.
Fixed zero-day issues in Windows 10 include a flaw in Windows Remote Access Connection Manager, a bypass in Secure Boot, and a hole in TPM 2.0 (somewhat ironic since this is a security feature required for upgrade to Windows 11functionality that some Windows 10 computers don't have, which excludes them).
Analysis: Faulty Thinking
Reading about security vulnerabilities is always boring and dry, and they're often found in parts of Windows that you wouldn't go anywhere near – like the Dial-Up Connection Manager (and one of the zero days is a bug in the fax modem driver, believe it or not).
However, there are still more than 170 security problems – and this is just in one month. In six months, you'll see a thousand of these little holes in Windows 10, and over time, the old OS will become a veritable security sieve, so to speak.
The way these vulnerabilities are multiplying underscores why it's best not to use Windows 10 without security updates, even though some people will undoubtedly take this course (as happened with Windows 7).
If you want to argue that you don't really need security updates for Windows 10 from Microsoft, I a recent article explains why you're likely doing this. And Windows 10 really has no excuse as consumers can get free year of additional support via Microsoft Extended Security Updates (ESU) program (and although there is a slight catch with this ESU, in my opinion it is no big deal).
