Windows – How to check if a specific Windows security update is installed

Securitywannacryptwindowswindows 10

Given that the WannaCry ransomware exploit is going around I wanted to check if my computer has the specific security update that should stop the vulnerability – apparently, MS17-010, assuming I'm understanding the vulnerability and that is indeed the right patch. How would one check that detail?

Microsoft tries to give some detail but it's gibberish to someone who's not well versed with registry keys (I think I touched them once before to dig out a stubborn virus back when XP was still a thing – that's it.) Other searches give some clues regard command line options but they're not all that clear and I don't like running commands I don't understand.

Here is a way to check this for windows 10 (Version 1607): As noted here https://support.microsoft.com/en-us/help/4013389/title in section "Windows 10 (all editions)", the security update file name for MS17-010 must be Windows10.0-KB4013429-x64.msu, so the kb number for this patch will be KB4013429.

Then in the windows 10 update history check for an entry containing the KB4013429. At my system this patch was successfully installed in the mid of march and is named cumulative update for windows 10 version 1607 for x64 based systems (KB4013429).
