- Windows 10 received its latest security update
- It fixes 172 security flaws in the operating system, including six zero-day vulnerabilities
- It’s hard to imagine how these security breaches will add up over the months for those who don’t sign up for extended support.
Windows 10 has received its latest update – at least as far as official support is concerned – and it kind of reveals to us the dangers you might face if you continue to use the operating system beyond its end of life.
Bleeping Computer reports that the October 2025 Update contains numerous fixes for security issues in Windows 10.
In fact, this latest cumulative update for Windows 10 contains the cure for 172 security vulnerabilities, including six zero-day vulnerabilities.
A Zero Day Vulnerability is a security flaw in Windows 10 that Microsoft was unaware of when the attack vector emerged and was made public. The name refers to the fact that Microsoft had no days to respond to the threat (in other words, it was not discovered by the developer and fixed in advance – as is ideally the case).
These are therefore worrying vulnerabilities – as malicious actors could attempt to exploit them, given their unpatched nature – and the corresponding fixes are contained in this October update.
Zero-day issues fixed in Windows 10 include a flaw in Windows Remote Access Connection Manager, a Secure Boot bypass, and a hole in TPM 2.0 (somewhat ironically, as this is the security feature needed for an upgrade to Windows 11, a feature that some Windows 10 PCs are missing, excluding them).
Analysis: erroneous thinking
Reading about security vulnerabilities is always boring and dry, and often they’re in parts of Windows you won’t go near – like the dial-up connection manager (and one of the zero-days is a flaw in a fax modem driver, believe it or not).
However, more than 170 security issues remain here – and that’s in just one month. Six months later, you’re faced with a thousand of these little holes in Windows 10, and over time the old operating system will become, so to speak, a real security sieve.
The way these vulnerabilities are multiplying highlights why it’s best not to continue running Windows 10 without security updates, even though it’s a solution some people will undoubtedly follow (as happened with Windows 7).
If you want to argue that you really don’t need Microsoft’s Windows 10 security updates, I explained why you probably do in a recent article. And there’s really no excuse with Windows 10, given that consumers can get an additional year of support for free through Microsoft’s Extended Security Updates (ESU) program (and even if there’s a small problem with that ESU, it’s not a big deal in my opinion).
