The tenth modification of Windows until recently suited almost all users. At least, the installation of updates in it could be disabled forever. Despite this, Microsoft has taken a completely unprecedented step by launching a new mechanism for installing updates, regardless of whether the user wants it or not. Naturally, at the end of the installation, a system restart always follows. And if it happens like at the time when you are working with an important document? After a sudden reboot, changes may not be saved! Let's see how to disable the automatic restart of Windows 10 so that it does not start at the most inopportune moment for this. There are five ways to offer for use, among which, however, you will not find methods for completely deactivating the Update Center and all its related services, since at the moment such a functionfrom the side of the corporation is completely blocked.
How to disable automatic restart Windows 10: setting the activity period for installing updates
Let's start with the least radical solution, which will not disable automatic restart, but will allow you to instruct the system so that updates are not downloaded or installed at a certain time while you are working at the computer. To do this, open the options menu using the Start button or the Win + I shortcut, then go to the security and updates section.
First in the list will be the menu related to the settings of the "Update Center". Click on the link to change the activity period.

The system will prompt you to set a time interval when you normally use your terminal, so that no update-related activities are performed during this time.

Note: just in case, you can use the advanced options and turn on the display of notifications about the need for a restart, so that the restart is not performed unexpectedly for you. You can also postpone the installation of updates, but at the maximum such period is no more than thirty-five days.
How to cancel the automatic restart of Windows 10 if the updates have already downloaded?
But what if the system has already downloaded the necessary updates and is about to install them? Disabling automaticWindows 10 restart cannot be deactivated in the same section, but you can use the restart options link.

In the settings window, simply specify the day and time when the updates should be installed. In a sense, this is equivalent to the situation when you put off installing them.
Note: if there are no downloaded packages, the link described above with all its settings in the "Update Center" section will be absent.
Setting the restart prohibition in group policies
Now let's move on to more effective ways and see how to disable automatic restart in Windows 10 using the group policy options management section for this. This toolkit is called through the Run console by entering the gpedit.msc command (which corresponds to the full name of the executable file in the System32 directory).
Here you need to expand the computer configuration branch and go down the folder tree through the administrative templates to the Windows components section, where the Update Center directory is located.

On the right side of the workspace there is a setting that disables automatic restart if users are working in the system. After calling the editing of the parameter by double clicking, you must set its value to the enabled state, and then save the set options.
Actions in the registry
Now it's time to saya few words about how to disable the automatic restart of Windows 10, if you use the system registry for this. The actions are similar to what you did in group policies, only they are performed using a different technique.
Call the editor from the Run menu with the regedit command, and in the HKLM branch, through the SOFTWARE and Policies subfolders, get to the WindowsUpdate directory. It has a subfolder AU, and in it on the right in the window there will be the coveted key NoAutoRebootWithLoggedOnUsers. If for some reason it is not there, you will need to create such an entry in the form of a 32-bit DWORD parameter yourself.

Double-click to edit the option, and set the value to one.
Pay attention to two important nuances! First, unlike group policies, when performing any actions with the registry, a restart is required. Secondly, the values set in the registry are higher in priority than similar group policy options. In other words, if you change something in the registry, a similar setting in the policies for changing will become unavailable. But when setting options in policies, changing them in the registry will not be difficult.
Scheduler Tasks
Finally, you can turn to the so-called "Task Scheduler", the role of which in the system parameters, many users greatly underestimate. In the Run console, enter the control schedtasks command, and after starting the applet, go to the library"Scheduler". Then it remains to go through the Microsoft and Windows directories to the UpdateOrchestrator section.

In the field of installed tasks in the central part of the working window, find the Reboot parameter and select the option to disable it via RMB. The installation of available updates will be performed only in case of a manual restart of the PC or laptop.
Note: if you want to simplify your task as much as possible, you can use a special program called Winaero Tweaker, where the option to disable automatic restart can be found in the Behavior section.
