Reopen Notepad++ after update, restart or shutdown Windows 10 from where I was
In theory, shutting down windows and having application saving their settings, does work BUT only if there is enough time left to do so.
What happens on a windows shutdown is that windows sends a WM_QUERYENDSESSION message to all running programs.
As we see here, npp handles this case.
Now the application has 5 seconds to handle this request, if it can’t it will be terminate.
So, there is no guarantee that a clean application shutdown can be proceeded on a windows shutdown therefore my recommendation would be to exit your application explicitly.
@PeterJones Sorry. It happens with 7.7.1. My backup settings are to remember the current session as they have been for several years now. It used to work very reliably. I use Notepad++ for my todo list and for a couple of text files I know I need every day.
Exactly when it became unreliable or why I’m not sure unfortunately. All I can say is ‘sometime in the last few months’. It might be when Windows is shutdown because of a forced update. Closing Notepad++ is fine. Shutting down Windows manually appears to be fine.
if it used to work previously, did you change something?
Like installing other plugins or formerly you used to use local files and
now you are using files on the network? Something else?
If it is a forced shutdown, it might be that npp has only 1 second left to do its config saving.
However, my recommendation stays, close your apps explicitly if possible.

Something has surely changed. I had the same issue, but I think I managed to solve it. My N++ was always downloaded as standalone and saved in a custom path. Recently auto-updater kicked in and I allowed the installer to run, but I changed install path to my custom path. This is when restoring session stopped working. Today I downloaded a standalone version and overwrote the installed one. I tried once and session was recovered after closing.
Maybe this brings a hint or something.

the new version, seems to solved the ȚsessionȚ problems. Thank you.

On Friday I discovered part of the problem. I started shutting down my computer prior to leaving work and shutdown was blocked by several applications including Notepad++. When I cancelled shutdown I discovered that Notepad++ was prompting me to reload a file that had changed earlier in the day - in fact the one I like to keep open.
So I clicked ‘Yes’ to tell it to reload the changed file. What actually happened was that the tab closed, leaving just one other tab.
And of course when I reloaded Notepad++ today only that other tab has loaded.
This scenario could be quite common. I’m a programmer and the file I like to keep open will often change as I change branches during the day but I don’t always notice.
This is with 7.8.1.
@Andrue-Cope I have the session issue with 7.8.1. In the past if my laptop refused to wake up from sleep mode, a power cycle did not affect the session at all… all open files, all changed files, all “new” files would come back up right where I left them. Now, changes are lost as are new files. I hope there is a fix for this as it is one of my favorite features (out of many) of Npp.
Sorry, but this doesn’t make sense to me.
Npp writes the new session information on application exit and this
has been since it was introduced, as far as I know.
So, when putting a laptop in standby it will comeback with the current
used files on a normal wake up but it won’t comeback with the newly
added files on a power cycle as it hasn’t been written those new files to
session.xml yet. The same might happen if npp gets forced to exit.
If there is no time to write to session.xml those new files get lost.
The only way to make it work, to have the newly created files get saved
in session.xml always, would be to add them whenever one creates a
new one or opens an existing one. But this, obviously, has a drawback
as well, the session.xml would get written constantly and in terms of
performance, IO operations are one of the worst things, not to
mention that maybe 99% of those operations might be useless as the
files get closed during runtime.
Well I think what I’ve seen is a bug. If I’m asked ‘Do you want to reload the file?’ and I click [Yes] then that’s what it should do whereas it actually closed the tab. I’ll try and replicate it tomorrow as Friday night is when I normally give my work machine a rest.
Just to be sure, 100% agreed - your case, "Do you … ", should be handled having those open tabs in mind.
@Ekopalypse Thanks for the reply. I just did a little controlled experiment and I see where the “new” behavior may be.
With my saved list of opened files… the ones I really care about… loaded. I created a new file with junk in it and left it unsaved. I created a second file, saved it, and then added some changes and left it that way. Then I closed NPP.
Past behaviour would be NPP would exit without any further input. Restarting NPP would open my session where it left off with saved files, new unsaved files, and changed files retaining their changes. This is what I am accustomed to.
However, with this last update, I now get a question asking if I want to save each file “needing” a save. I want the state saved, but I don’t necessarily want them written to disk by the filename or “New x”. So what I am seeing is different from what Andrue is seeing.
I may try to roll back this update if I can still get the older executables.
I guess I see. What I assume is that the session setting isn’t set anymore.
As far as I remember this setting was set with previous npp versions automatically but since some recent versions the community asked to change this to not set.
In order to get the same behavior as with your previous version you need to goto
Settings->preferences->Backup and tick
Remember current session …
and if new, aka unsaved files, should also be available tick
Enable session snapshot …
That did it. I needed enable session snapshot. That one setting was all I needed… darn lost a days work because of that. Thanks @Ekopalypse.

You are perhaps living dangerously with this workflow. If I were you, I would name and save files to disk yourself, and then have a separate backup mechanism that doesn’t involve Notepad++.
@Ekopalypse It did the same thing. This time though I re-opened my file and it was there when I launched NPP this morning. I usually only give Windows half a minute to shut down then force shut down so I’m guessing that this is what’s tripping me up.
Whether fixing the prompt handling would also fix my typical scenario I don’t know. Possibly not.
Half a minute should be more than enough for an app to save its settings but …
I only have win10 in a VM so it isn’t that convinient to do testing on this
and digging through the code didn’t reveal anything obvious.
Just while writing this I think it might be ok to create some tests using
WM messages only and not restarting the VM always.
I’ll come back on this.
