annoying issue of "How do you want to open..."

I the annoying issue of "How do you want to open..." but it wont tell me what the program is that is trying to be opened. Just allowed Windows 10 to do it's upgrade from 7 last week and it wont stop even though I have already entered the apps to use with my normal programs. HELP!!!!!!

If you don't know what program/file is trying to be opened, then do you mean that some programs automatically run them?

Try to check if apps are automatically running by themselves. Go to Task Manager>Startup.

When was this generated? Was it from rt click, Open With, or by some other means - an apparently random popup?
Do you perhaps mean file, not program?

'but it wont tell me what the program is that is trying to be opened'

If so, just try opening it with one of the programs, and then work backwards to find the origin of this prompt.

If it were Open With, you should have two more entries at the bottom - Search the Store, and Choose another App.

Note: you will get this prompt when trying to open a file type which was associated, after installing a further registered program that can also open that file type. Annoying, I find.

Please note that to set your defaults in Win 10, you must do this from the Control Panel, Settings, or Open With- not from within programs- that's not been supported from Win 8.

Hello, I do have programs that run in the background looking for ems files. Manager>Startup does show what's running but not what need attention. I can shut down those programs but the screen still pops up. I am running Chrome too if that might be an issue.

It would help you to try to open the file. Then you can see which file the system is attempting to open.

It will not show what file I need to open that is causing the pop up.

Since you mentioned .ems - try this

Launch Command Prompt (Admin)
Right click Windows Logo on Taskbar, pick Command Prompt (Admin)

then enter the following command

reg query HKCR.ems /s > %TEMP%HKCRems.txt

exit

Please attach %TEMP%HKCRems.txt to your next post.

Hi, is that ('will not') a prediction, a guess, or have you actually tried it? You should have a chance to see the file name I'd have thought.

And you don't need to open a file yourself.. the file has already been selected and is going to be opened - or at least accessed- by the program you select.

Sorry, I should have stated that when this window pops up, it does not tell me what program needs an app assigned to it.
