I was able to get rid of XNVIEW by downloading it and using it's own uninstaller.
Have tried method suggested by Pyramid 10 with photoscape without success.
Can't figure out how to do what is asked.

Your next suggestion?

*Think

As always, there seems to be lots of alleged fixes out there, which may work on versions earlier than Win 10... but not with Win 10. The struggle for getting rid of this now un-needed bloat seems to be wrapped up in file permissions. But even when I try to clobber it with administrative authority, it won't budge. One fix suggests that you can use disk cleanup to get rid of it by selecting previous installation files. Heh. Yeah. Just TRY and find that option in Win 10.

Ok. Somebody hopefully has managed to resolve this inigma. Step by step, please.

 

Is there any way to permanently get rid of this nag screen?

Every so often when I start up I get this annoying nag screen. I'm really not interested in any of the options offered but there seems to be no way to tell Micro$oft to go away and stop pestering me with it.

It's really starting to get under my skin so if anyone has any suggestions for how I can permanently get rid of it I'd be mightily grateful.
