What is the error code?
Do you have Malwarebytes installed? If yes then this is preventing install of updates for many users, the suggestion is to disable all protection & turn off ‘start protection when Windows starts’ then restart the PC & try downloading the update again. If it still fails then open control panel>Programs & features>Turn Windows features on/off & disable NET 3.5, restart when prompted then try installing again.
The error code is 0x800f085. Also,I found this on the Microsoft site.
Since a few days I try to download and install KB5016688 but keep getting or if it does work I have the following problems:
No sound in the taskbar
no internet,
long before starting up,
the icons in the taskbar don't appear immediately,
also a sinner in the taskbar,
black screen during startup.
I am forced to delete the KB every time, to restart it to make windows run normally again.
I tried this several times.
Guided by microsoft support, yesterday, my computer was tinkered with, among other things, an appropriate latest version of windows to to fix any eventual problems with downloaded updat KBs etc...
After about two houres...restart laptop...same problems.
Because I can't prevent downloading and installing the KB in question, I remove it after updating...
I hope for a solution but...
So with the previous I don't think I am going to install this update.
