Windows 10: what is TWINUI ?

i got 2 popups saying "an app default was reset" - an app caused a problem with the default app setting for ".avi / .mov so it was reset to TWINUI" what is the cause of these errors

:)

 

I cannot open images and get "Class not Registered" error

Just found a blog (What is TWINUI in Windows 10 all about? – Ctrl blog) that I think says that wherever you see TWINUI, that means there's no default set up and because of a bug some users can't change their system's default programs in the Settings app. It's usually
because of a System Registry corruption. I'm not tech savvy, so instead of restoring the registry (that sounds scary), I think I'll just do what I did for now for anything else that has (the evil) TWINUI.

 

remove TWINUI from default apps

That is kind of funny. TWINUI means “open this with the app chooser”, so it indicates that you have no app set for this type. Quite interesting to see that
this can actually happen. Thank you for sharing screen shots.

 

hmmm

so registry may be corrupt? one problem after another on my pc, how do i keep my sanity. ill look into this furthur, cheers

Please provide more info as it is needed to help you with this to determine the core problem.

When does this pop up happen, are you trying to open a YouTube video or a pic on your 'puter ?

What other problems are you having and when did they start.
You have mentioned in another thread that you have many problems with a 2 month old 'puter.

All these might be interconnected and need to be looked at for a common connection.

I would advise you not to go into the registry until a member who has proven experience in this area
advises you on how and what to change in advance.

Please provide the the needed info in your next post before you try to do anything else which
may make your problems more complex.

 

earlier I ran wise registry cleaner and cleaned up stuff. so far, that problem isn't showing up. the only thing I found that was corrupt was Microsoft store..rebooted after downloading app diagnostic pgm. expect more glitches as the weeks progress lol

 

What was the name of this program ?

Most members here use CCleaner Free version it is a superior program.
CCleaner - Free Download - Piriform

 

its called apps diagnostic10. I scanned pc with it and it helped to identify problem

 

What about all the other problems you have been having ?
Can you list them ?

 

the areas that had error was .AVI and .MOV that's all. but haven't seen errors since after reboot.

 

@Pathfinder Malcolm, if something screwy happened and your extensions (.avi, .mov, maybe others) are messed up, look at Shawn's tutorial for resetting the defaults to clean up. Might help.

TWINUI basically means to open a file from the web with your default app, if any. Here is a basic definition of the meaning.

very good. I saved zip "just in case" ill read that docu more later, cheers

 

If you still have Wise Cleaner installed, I suggest uninstalling it and replacing it with CCleaner.
It is a very safe program to use.
