Disabling Automatic Updates on Windows 10 (WiFi)
There isn't any straightforward way to disable these updates, but it is possible to trick Windows-quite literally.
Sadly, the trick works only if you are on a WiFi network.
On the brighter side, it works on any variant of Windows 10.
Open the Settings app and select Network and Internet. Now connect to your hotspot. Your screen must show something like this.
Select Advanced Options. Toggle the Set as Metered Connection switch to On.
Now, hopefully, your computer should stop downloading updates automatically.
A word of caution, though. I am not responsible for any damage that may occur to your computer as a direct consequence of not installing critical updates.
