The KB5043076 update is one of the most important for Windows 11, especially if you have a Ryzen 7000 or Ryzen 9000 because it can improve gaming performance by up to 11%. According to AMD, much of this great performance improvement is due to optimizations implemented in the jump predictor.

This performance improvement has caused many users to download and install the update, which is completely optional. It’s understandable, after all, any free performance boost is welcome, but unfortunately it was also confirmed This update is causing problems. Microsoft is not on track with Windows 11 updates.

If you planned to install it, go ahead, but keep this in mind you take a riska reality that unfortunately seems to be our daily bread when we talk about Windows 11. Below I explain some of the issues that have been confirmed with this update.

Issues with Windows 11 KB5043076

This update repeats an issue already confirmed by an optional update released in August, which causes File Explorer to suffers an unexpected closure when opened from the main panel.

There have also been reports that the “Phishing Protection” technology present in Windows security, resets and disables automatically on activation. This happens when you shut down or restart your computer.

It doesn’t end there, other users have performance issues with Windows 11 search function taking too long to load, router connection failure, errors and failure to load certain applications which is only temporarily resolved by turning the PC off and on again.

What to do if you’ve updated and are experiencing these issues

The only known solution at this point is to uninstall the update. To do this, you must enter «Windows Update > Update history > Uninstall updates». Once there you will see a list with the latest optional updates installed, you will just have to search for the KB5043076 update and uninstall it.

To complete the process, restart your computer and enter Windows Update again after Windows 11 finishes booting pause updates for a reasonable amount of time to prevent it from being downloaded and installed again.

I’ve told you this many times, but I’ll say it again. When we talk about Windows 11 and updates it is much better to wait that these have been available for some time before installing them, as this way we will know whether they actually arrived safe or not and avoid many problems.
