Windows 10: URGENT: Wannacry fix - THIS UPDATE NOT APPLICABLE TO OS

Hello,

BIG PROBLEM.

My organization is responding to the Wannacry update by rolling out new Windows 10 machines to critical users who run Windows 7.

The OS version we are rolling out with is Windows 10 Enterprise, 1607, 14393.1198.

The problem:

1) We are attempting to meet compliance by patching the systems with the Wannacry fix KB4013429.

2) BUT, when we go to install it says "This update is not applicable to your operating system."

What's going on?

:)

 

Windows 10 versions not affected by wannacry

Thanks for the reply and I take security seriously and thankfully am not a click happy user as you mention. Though, with something like WannaCry, I'm at the mercy of ANY click happy user who is on the same network as I am.

After looking in to this more, I believe my personal machine running windows 10, even though they are not updated to the latest version of windows, are patched and safe from WannaCry.

For anyone else trying to figure this out on windows 10:

• Click on start icon
• Type "winver" and hit enter, this opens the windows version dialog box.
• Take note of your windows version AND OS build number.
• If your Windows Version # is 1703
  • You are protected against this current exploit.
• If your Windows Version # is 1607:
  • Check if your OS build number is equal or greater than 14393.953
  • If greater, you should be protected from the current WannaCry exploit.
  • If it's not, you should upgrade
• If your windows version # is less than 1607, upgrade immediately.

Wannacry

Windows 10 version 1607 OS build 14393.1066

Is this version open to attach from Wannacry?

 

Microsoft Update Catalog

Try downloading the proper version from the link above. The one that say server may work. I am assuming that you use a 64 Bit OS.

 

Welcome to TenForums @ricecracker

KB4013429 (os build 14393.953) is not applicable to your system because you have already got KB4015217 which is what took your build up to 14393.1198.

Explain to your 'higher ups' that cumulative updates include all previous fixes and that...

https://support.microsoft.com/en-us/...date-kb4015217


You can show them the update history here https://support.microsoft.com/en-us/help/4000825 so they can trace back the chain of replacements all the way back to that KB4013429.

 

Well... in short, taking in mind the build number, you are already patched and up to date, nothing more needs to be done.

 

Indeed. Danke, everyone. This was helpful.
