One of the reasons why it’s not worth jumping to Windows 11 is the issue of faulty updates. That happened a more serious problem than it seemsand Microsoft still hasn’t found a solution to avoid or at least reduce the impact and problems caused by these types of updates.

Update KB5041585 became real headache for some users because it causes a number of problems that not only affect the performance of the computer, but also have a negative impact on the security and operation of certain applications under Windows 11.

I’ll tell you exactly what happens. After installing this update on Windows 11, several users experienced errors during the installation indicating that it was not completed. Still, part of the update seems to be installed, causing problems They make the computer much slower.

It also creates a security error which allows attackers to access our computer if we are using IPv6, which makes it easier to execute code on our PC by sending specialized IPv6 packets. As if that wasn’t enough, there is also a Vanguard compatibility issueanti-cheat technology used by games like League of Legends and Valorant, so we won’t be able to play any of them.

Avoid this Windows 11 update

It’s the smartest thing you can do right now. If for some reason you were unable to do so and it tried to install but failed, chances are you’re running into some or all of these issues. If you start to notice that your computer is slower, this update is to blame, as there have been confirmed cases of powerful computers that They were almost unused.

Based on the first reports I’ve had a chance to see in Microsoft’s feedback center, as well as information shared on the Reddit forums, it appears that this loss of performance is occurring for several reasons. Affected users speak among others high consumption of RAM and graphics memoryas well as scenarios in which a 100% CPU utilization 24/7.

Whether the installation of this update is complete uninstall and revert to the previous version could be the solution. In case Vanguard fails you disable the protective layer “Hardware-enforced stack protection”, something we can do directly when we get a “driver cannot be loaded into this device” warning, will make it work again, but we’ll lose an important layer of security.

I think it’s a good time to remind you that deferring the installation of updates in Windows 11 is highly recommended and very easy. By postponing the installation of updates for a few weeks you will not suffer this type of failure which are usually identified a few days after they are launched, avoiding a potential source of problems. That’s what I do with my PC, I put off updates for a reasonable amount of time.
