Windows 10 automatically downloads and installs updates to make sure your device is up to date. To finish installing the update, your device will need to restart. If you’re asked to restart your device while you’re busy using it, you can schedule the restart for a more convenient time:
Select the Start button, then select Settings > Update & security > Windows Update .
Select Schedule the restart and choose a time that’s convenient for you. Note: You can set active hours to make sure automatic restarts for updates only happen when you’re not using your PC. Learn about active hours for Windows 10
If you’re using Windows 10 Pro or Windows 10 Enterprise, you can choose to temporarily pause updates from being downloaded and installed:
Select the Start button, then select Settings > Update & security > Windows Update . Under Update settings, select Advanced options.
Turn on Pause updates. Note: After a certain amount of time, or after canceling a pause, you’ll need to install the latest updates before you can pause updates again.
There is also a registry change you can make.
IMO, only this would be sufficient:
HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\WindowsUpdate\AU
Key: NoAutoUpdate
Type: DWORD
Value: 1
To enable updates again, remove AU registry key or delete NoAutoUpdate DWORD.
Hope this helps. Good luck!
