I was reminded tonight why one should avoid using Microsoft's latest desktop operating system, Windows 10, for any critical system. I had postponed some work on a Microsoft Windows 10 system that I was connected to by a Remote Desktop Protocol (RDP) connection. I had been working on the system a few days ago and returned to using the connection this evening only to see the system was going to reboot in a few minutes for an automatic update. I often have many applications and windows open at once and I knew there wasn't enough time for me to save all of my work, but I thought, even though I only had a few minutes remaining until the forced reboot, that I could at least postpone the reboot until tomorrow evening using the steps at Changing the time for a Windows 10 automatic restart that I've used before to postpone the forced reboot due to a software update. However, tonight when I got to the Windows Update settings window where a "Restart now" button appears, I was not able to click on "Change active hours" because that option did not appear under the "Restart now" button. I frantically tried to find another alternative. I thought, perhaps, I could hibernate the system to save the work in progress, but it was too late; the system rebooted and I lost all of the work in progress, much of which I'll be unable to recreate, since it had been several days since I had been working on the system and I now can't rememeber what I had put in some open Notepad windows, etc.
I understand the need to update systems to install security patches to prevent malware attacks, etc., but I've never lost data on this system over the course of several years due to such issues. I've only lost data due to Microsoft's automatic reboot "security feature".
I've read Microsoft is deigning to give their users a little more control over reboots due to automatic updates with the release of the Windows 10 "Creator's Edition" in April of 2017, e.g., see Windows 10 now prevents random reboots during updates, but Microsoft's decision that rebooting a system while a user is working on it even when there are open unsaved files, because Microsoft has decided that "this is for your own protection and too bad if you lose data" gives me a much more negative view of the company and its products. And I know there are many others similarly angered at the company after losing work to these forced reboots in Windows 10.
