Uninstalling windows update

[Elonn]

Sorry if this is not the right place to post this relatively new here

After the last windows update KB4530684 my internet slowed down drastically, when PC is off internet runs at 100mb/s (testing from phone) as soon as I hit the power button it drops down to 5mb/s.

I uninstalled the other update but I cannot uninstall this one, tried through CMD aswell did not work.

Can anyone tell me how can I get rid of it.

This is the error when I try to uninstall through windows update history

Bunch of phrases that don’t make sense to me.

” My internet slowed down drastically” “when pc is off internet” “testing on my phone”

 

When you mean slowed down you mean your final throughout onscreen I take it?

There are many parts to that linkage.  Also I’m assuming slower than before.  This implies there is a bottleneck somewhere.  The OS has a lot of settings in it.  It could slow things at many points.  The problem is removing an update may not restore those settings.

 

also “testing on my phone” do you mean you are independently testing the same connection the windows machine uses to show that it remains the same at the router end?  Phones have ways to access the internet that are not always the same as desktops.

 

”when pc is off internet”. This makes no sense at all.  May go to the definition of “internet” in this case.

I'll just simplify it because I know its the last windows update causing it already read the news for past 3 days.

Forget all the slowing down thing, how do I uninstall an update when I get these errors while trying to?

Edit: the update is KB4530684
