what is TWINUI ?

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

but wise cleaner does incredible job of cleaning a lot of stuff, including tracers. lots of tracers when I use gfx program and watching YT vids. maybe ill save ccleaner file for reference

OK the, its your choice.
I can only suggest a safer program from experience, can't make you use it.

This notification that an app default was reset is caused by running any older app that checks for or resets file associations in a non-approved way. Some methods that used to be legitimate are deprecated in the latest versions of Windows 10.

Note: The app reset is usually triggered when a 3rd party program changes file associations in an incorrect way, instead of directing users to the Default Apps or Default Programs window. Since the hash algorithm is in place, incorrect modification of file associations in the registry would cause Windows 10 to reset the associations settings to Windows defaults.
The ultimate fix would be to upgrade the 3rd program (viewer, browser or anything) you’re using and make sure it’s compatible with Windows 10. If that doesn’t help and Windows 10 continues to reset the associations, then use the registry fix below.

I have one such app that triggered this notification - Office Starter 2010 that was on my OEM Win7 PC before the free upgrade. From Excel or Word, using 'File open' would trigger a string of these. At first there was no problem. Then after one of the 1511 Cumulative Updates the notifications started. Since the AU they seem to have stopped. Strangely, although Windows said it had reset to the default applications, on checking none of the file associations had actually been reset.
