The latest security patch for Windows 11, KB5015814, seems to be plaguing a growing number of users, with lots of error codes during installation and even some instances of boot looping. Since this is a security update, it’s not the kind of patch you really want to skip, as it could lead to your machine being compromised if you decide to postpone it. Not very happy.
The patch notes include a single line for the highlights of the update:
- Fix security problems for your Windows operating system.
Great, thanks Microsoft. However, there is a bit more information at the bottom of the page, including the fact that this patch includes improvements introduced with KB5014668 (opens in a new tab) and the PowerShell log has been fixed — hardly anything affecting most, but I’m sure our IT department will be delighted with the news.
There is also a known issue with .Net Framework 3.5 applications failing to open and having general issues. Some users find it helpful to disable .Net Framework 3.5 before installation. Disabling Malwarebytes first can also help here. There is a workaround on the patch notes page (opens in a new tab)may be useful.
Another known issue affecting IE mode in Microsoft Edge. Obviously, model dialogs can prevent Edge from responding, which is not ideal. The solution here is to use Known Issue Recovery (opens in a new tab)—In other words, this is completely broken. While there probably aren’t many users running IE mode, since it’s basically to support older sites that require Internet Explorer 11 which is now deprecated, it will annoy anyone who has to rely in it.
This is not the first time users have had issues with such automatically applied security updates, and the curse of the Third Patch has become a minor issue because of it. This probably won’t be the last time there is a problem either.
While these patch issues are relatively minor, nothing can prevent more serious problems from appearing in the future. Your best bet is to keep your machine backed up, you know, just in case. But of course, you’ve already done that, haven’t you. Aren’t you?
