Microsoft releases Windows 7 KB3178034 update to patch remote code vulnerability

Microsoft hasn’t abandoned its Windows 7 users: it rolled out a new security update to patch a recently detected vulnerability. This vulnerability could allow the remote execution of code if users either visit a specially crafted website or open a specially crafted document.

If you set your computer to install updates automatically, then KB3178034 is already installed on your machine. In case you turned off the Windows Update feature, you can download this security update straight from Microsoft’s web page.

Before you install this security update, you should know that Windows Server users are complaining that KB3178034 breaks their ASP.Net pages. Fortunately, they managed to uninstall it and fix the issue.

This morning KB3178034 was installed on my Windows Web Server 2008 R2 through Windows Update.  Once the server was rebooted, someone tried to log in to one of my ASP.NET applications and got an error about LocalFunctions.  […] I looked at what was installed through Windows update and started with that one (it was top on the list).  Uninstalled it, rebooted the server (it made me), tried the application again and it worked.

So far, regular users haven’t complained about KB3178034 causing any issues to their system, and it could be that this bug manifests itself only on Windows Servers.

Microsoft ended mainstream support for Windows 7 last year, but the company still offers extended support for this popular OS.  According to NetMarketShare, Windows 7 still runs on 49.04% of the world’s computers, while Windows 10 has a global market share of 19.4%.

Microsoft is trying hard to convince Windows 7 users to upgrade to Windows 10, but not even the free upgrade offer has convinced users to give up on their good ol’ OS. Judging by the current trend, we dare say that Windows 7 is the next Windows XP, with the OS poised to run on the majority of the world’s computers even after Microsoft ends support for it in 2020.
