After CU KB4462919 W 10 v1803: can you change default program?Y/N

Cumulative Update KB4462919 Windows 10 v1803 Build 17134.345 - Oct. 9

I can't change default program, am I the only one? (I do not care to fix it).

If you can and I can't It must be a Bug, not a feature.

MS we found another bug

Thanks Maverick!

Me too, i detected it where I preparing a new virtual machine for the work, where I uninstall that update the assignation return to normal, the rarely issue is that only fails with some programs, I don't know whats the cause, but I'm sure that is caused by the KB4462919 Update

I was thinking more like this I associated pdf with Nuance Power PDD rather than the default Edge Using file Association type

yes, I try it and nothing, I try to change the default program for xml to open with notepad++ after the update I only can choose internet explorer and edge, and if I has a file associated before the update to notepad++ and change the default after the update, I can't return to notepad++

Is a rarely issue because not is with all files is only whit some extensions, I try it with txt, sql, xml, jpeg, png

Thanks roy111, and you're not the only one. I was getting pretty frustrated with this error today. Control panel methods also failed to set the associations on my machine. Oddly, I could change a previously assigned association but only once. New file types could not be assigned at all. Removing KB4462919 fixed the problem. I read somewhere the problem may also be fixed with 1809.
