The first ESU update for Windows 10 PCs is update KB5068781, officially known as “2025-11 Cumulative Update for Windows 10 Version 22H2 (KB5068781)” and now available to those enrolled in the ESU.
This is the first security update for Windows 10 PCs, and you should install it (as well as all future security updates) to keep your system guarded against ongoing risks and threats. These updates will keep coming over the next year until Microsoft ends the ESU program.
What does update KB5068781 do?
With the ESU program being a source of security updates, Windows 10 PCs will no longer receive feature updates. That means no new features will be coming to your Windows 10 PC anymore.
Update KB5068781 fixes 63 security vulnerabilities, one of which is already being actively exploited by hackers in the wild and is therefore considered a zero-day vulnerability. The update also fixes a bug that issued a false warning on PCs eligible for the ESU program that they had reached the end of Windows support. Microsoft recently released an emergency update that fixed that false warning.
How to get the KB5068781 update
As soon as your Windows 10 PC is registered for ESU, it will automatically install KB5068781 (about 200MB) because it’s an important security update. You don’t need to install it manually. After installing this update, your Windows 10 PC will have Build Number 19045.6575.
Update KB5068781 is also available for manual download via the Microsoft Update Catalog. Depending on your system architecture, this download ranges in size from 430MB to 776MB. But again, this manual download isn’t necessary for most—only in exceptional cases.

update KB5068781This update fixes as many as 29 elevation of privilege and 16 remote code execution vulnerabilities, among the total 63 security issues found in Windows. However, remember that the 63 figure does not include fixes for Microsoft Edge, as we’re primarily talking about Windows here.
Windows 10 KB5068781 patches a critical bug (CVE-2025-62215) where attackers could gain unauthorised access to the system. It means that if an attacker exploits the vulnerability, they can do pretty much everything that you can do as an administrator on your PC.
These vulnerabilities can be exploited through apps or other forms of attacks, but if you install Windows 10’s November 2025 Update, you’re safe.
