Surprise! Emergency IE patch preventing some PCs from booting

[javajolt]

Three days ago Microsoft released an emergency patch for Windows 10 to address a remotely exploitable vulnerability in Internet Explorer.

On release, the patch came with some known issues on some older versions of Windows 10 (though none on 1809) which are listed below:



Since then however, Microsoft has added a further, somewhat more serious issue, affecting some Lenovo PCs which may cause them to fail to boot.



The issue is only affecting PCs on 1607 ie. the 2016 Anniversary Update, who applied KB4483229, and therefore most likely business PCs which are able to delay updates.

Given the seriousness of the vulnerability, which was being exploited in the wild, issues cropping up is not a reason not to install patches, but it may make a case for delaying the installation for a week or two to allow more brave users to find the pitfalls first.
