Dude, You're a genius! The moment you started talking about an update from januari. i knew it was the update! Unfortunately, I am unable to uninstall this update, as it is marked as necessary update :(

Hi I am still facing the same problem and the Security Update KB5009543 is listed on update history but KB5009543 is not listed in that table from where we can uninstall update

Surely removing this update makes your system vulnerable?
Windows 11: switch on IKEEXT service (IKE and AuthIP IPsec Keying Modules)

teach us the other method, please. My computer is not allowing me to do anything, I tried using CMD, I tried locating it via the way you have done, it is telling me. This is a very important update

I had this problem and before I found your video I upgraded to Windows 11. Did not fix the issue. I did a full wipe and system restore which did not fix the issue. The problem I have now is I do not see that Windows Update listed so I can’t remove it. Any suggestions?

Dont have KB5010793, tried KB5010793 says not applicable on my win10 pro. :(

But, if we want to install the Update again... what i should to do?

[aldiwidodo]
