KB3074674 Windows Update is a hotfix for fixing security issues in Windows 10 Build 10240

Microsoft appears to be busy fixing bugs, and the Redmond Company is now rolling out a new hotfix update called KB3074674 Windows Update.


The new update, is not available for all Windows users, unlike the ones which were released yesterday.

Microsoft released Windows Updates KB3074667 and KB3079904 yesterday, to fix critical security issues related to OpenType Fonts in all versions of Windows from Vista to Windows 10. The issue was once again related to Adobe, which has been under flask for severe vulnerabilities found in ts plugins and apps. The latest one, from yesterday, was in the Adobe Type Manager.

KB3074674 has been released exclusively for Windows 10, and to be more specific it is only for Windows 10 Build 10240. This update happens to be the second update for the latest build of Windows 10 Insider Preview, and its also the 2nd update in less than five days for the so-called RTM build. Last week, Microsoft released Windows Update KB3074665 to fix security and performance issues in Build 10240.

This is what Gabe Aul tweeted:

KB3074674 is termed as a cumulative security update and is described as:

This security update resolves a vulnerability in Windows that could allow elevation of privilege if the Windows Installer service incorrectly runs custom action scripts.

Additionally, this update includes non-security-related changes to enhance the functionality of Windows 10 through new features and improvements.

That is a really generic change log, and it is not the first time it has happened. Microsoft has drawn a lot of criticism for lack of information about the changes in the updates it releases. One particular user criticized Aul for the constant updates being rolled out, and pointed out that the general public will not like this practice. Aul replied stating that this only applies to the Insider Program, and that general users won’t see so many updates.

But for once I think I will have to disagree with what he said. This is exactly how users are going to react,given the lack of option to turn off or defer Windows Updates. And a few users from Twitter and the Microsoft forums, have reported that the new update, KB3074674, has failed to install upon rebooting. This is yet another example of why forced Windows updates aren’t a good idea. (KB33074665 also had many issues).

Microsoft should allow users to defer updates, to ensure system stability. Do you agree?
