Windows 10: Programs are opening automatically after reboot

Since Fall Creators Update, Windows remembers which applications were open at the time of system shutdown, and launches them automatically at system startup.
How can I disable this behavior?

Default Program Resetting Automatically

The Default Program for opening Images and PDF are changing automatically to Microsoft default (Paint 3D and Edge).

But I need these files to be opened with third party applications. If I reset the default program to my desired application in settings, It will be changed. But after some time or after reboot It will changing to Microsoft application as default!

 

How to safely delete Temp files in Windows 10?

They all can, and should be, deleted periodically.

The temp folder provides workspace for programs. Programs can create temporary files there for their own temporary use. Each program should delete all its temporary files when it closes, but for various reasons it doesn't always happen (for example,
if the program crashes, it never gets to do this). That's why it's a good idea to periodically clean out anything left there.

Also note that there are some program installations which work in two steps. The first step concludes by writing temporary files and rebooting. The second step starts automatically after rebooting and needs to find those files there (and then deletes
them when it's done).

Other than doing it automatically when rebooting (that would interfere with installations like the kind I described), it's always safe to delete the contents of the temp folder. Because it's safe to delete any temp files that aren't open and in use
by an application, and since Windows won't let you delete open files, it's safe to (try to) delete them at any time. If any fail to delete because they're open, they'll either be deleted automatically when the app using them closes, or you'll get them the
next time you delete manually.

Some people may suggest that you reboot before deleting anything, but that's not necessary, for the reason described above (on the other hand, it doesn't hurt to do it).

 

Hello shmu26, *Smile

The best way would be to close all apps before shutting down.

One workaround would be to press an hold the Shift key while clicking on Shut down in the power menu.

Another option is the Shut down context menu below to make it easier to shut down how you want.
