I actually don't know why a reboot is required for an update, but it seems it is.
I don't remember the exact wording, but I think it asks to restart Windows; that should be clear enough.
If you think it is not clear enough, you can file an enhancement request at https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform
Thank you for the link -- I will definitely make the request.
I am sure the window said "restart Windows", or "restart your computer", or something to that effect, and if we were assigning fault for the reboot, I am sure I was duly warned. It does not make for a good user experience, however.
My bigger complaint was about the hard-and-fast nature of said reboot, which didn't give me a chance to save my work. On this issue, if we were assigning fault for lost data, there was no warning and no reasonable expectation of such outcome.
I don't think there are multiple ways of rebooting. When you, or a program, initiate a reboot, then Windows will reboot - without giving you any options to save your work. Otherwise Windows would simply be unable to reboot.
But you are right: a little warning on the reboot pop-up (save all your work before clicking OK) would probably help many users in your situation.
Just to make sure I was sane, I tried initiating a reboot procedure by three different actions:
- Start -> Shut Down -> Restart,
- Allowed the system to reboot after installing Windows updates,
- Upgraded my video driver and allowed the NVIDIA installer to reboot.
In each case, I had a document open in Notepad and unsaved, for testing. In each case, the reboot process paused while waiting for me to respond to Notepad's dialog about saving, like so:
Just to make sure it works, during one of the reboots I waited for at least a minute before hitting "No" in Notepad's dialog. The reboot continued once I did so. During another reboot, I hit "Cancel". The reboot aborted.
Not so with Adobe updater. I conclude that there are, indeed, multiple ways of rebooting.
Just to let you know that there are indeed multiple ways for triggering reboot of the system.
Based on your input there is now a request in the queue for the next version of the updater to make it less forceful.
