Hi @Patrick Mor
No this will not block Windows from updating its OS. This is for blocking Windows from checking for app updates/drivers.
App Updates is defined as:
Microsoft product updates: These update other Microsoft products, such as Office. You can enable or disable Microsoft updates by using policies controlled by various servicing tools.
Driver Updates is defined as:
Driver updates: These update drivers applicable to your devices. Driver updates are turned off by default in Windows Server Update Services (WSUS), but for cloud-based update methods, you can control whether they are installed or not.
