How to Disable Windows 10 Automatic Updates?

Try this.

Go to Start Menu and search for Settings. Choose Networks & Internet.
You should be seeing the Wi-Fi section, now select Advanced Options.
You'll see the option for Metered Connection in this section, and below it the switch to turn it on. Turn it on.
This should stop downloading updates and if you ever want to update again, you will have to turn the Metered connection off.

In case of Windows 10 home edition here are some of the following options.

1. Use metered connection -

You can find this option in Settings > Network & Internet >Wifi > Metered connection.
2. Set the option to On.

2. GWX Control Panel - This small utility allows disabling of automatic updates from it's options panel. This utility works on all editions of Windows.

3. Show or hide updates - There is one troubleshooter utility from Microsoft itself. You can use this to give yourself an option to either ignore the download or show them for download.

The above mentioned tweaks work for all editions of Windows 10.

Here is how we can disable automatic Windows 10 updates -

The professional, Education and Enterprise editions of Windows 10 have access to registry entries thus allowing you to disable the updates. The Home users too can do it by following the below mentioned steps.

1. Preventing updates using connections
Set the connection as metered. Windows 10 will not download updates on a metered connection.
To do that, follow these procedure -
a. Go to Settings ->Network and Internet.
b. Scroll down to Advanced Options and enable "Set as metered connection".

2. Prevent updates of some specific nature
Windows allows you to block certain specific updates from downloading. You can use third party apps for the purpose.

3. By editing group policies

This method works only with Professional editions of Windows 10. Since you are Home edition, it may not be of any practical use for you.
To do that, type gpedit.msc on your start menu.

Windows 10 do not let your disable updates from control panel because of security issues. In newer version of Windows there are no unnecessary updates. If still you want to disable them then there are three method to do that.

1. Metered Connection (Only for Wi-Fi network)
a.) Navigate to Network -> Wi-Fi ->Metered Connection.
It will disable background use of internet which will save you data.

2. GWX Control Panel
This is a third-party application which you can download from the internet. It lets you disable automatic updates with just one-click. If you don't want to take much hustle then this will be your life saver.

3. By modifying services
a.) Press Windows + R simultaneously a popup windows of Run will appear. Open gpedit.msc using it.
b.) Open Computer Configuration\Administrative Templates\Windows Components\Windows Update
c.) After that find Configure Automatic updates and open it.
d.) Set its value to "Notify to download and Notify to install"

According to third is the best option because whenever there will be new updates you will see a popup and decided whether you want to download updates or not.
It is strictly suggested to download every single updates because they comes with many critical security updates and performance tweaks.

You may try the following simple step too.

Go to start menu
Type as 'Windows update'
Follow the instruction and use the 'never' update option or check list.

Hope it helps.

I tried a simple thing and it worked:

From your Start button, select Settings. Then from the list choose the top most Windows Update. The page will have a link for Advanced Options. Clicking on it, the page will have the first tab for "Choose how updates are installed", within that, there would be only two options,
a) Automatic (recommended)
b) Notify to schedule restart.

Choose the second one.
It will give you options to choose your time of convenience.
Select one time of your choice, they would also suggest one. You can also choose Restart Now, if it is time.
That's it.
