BUG in feature update to windows 10 version 1909 via enablement package (KB4517245)

Same problem here-it's appears to be a bug!

It's bad PC resources usage of new windows search UI

We have the same issue here with a few users. One of them the issue seems to be when you click File - Open in an application and then go to use the search in the top right of the find file window. The top right search in a normal explorer window is the main issue for another person. Either way something is not right with the top right search in File Explorer.

I was having the same problem when I was using the update (KB4517245), when I clicked in the search box, I had to wait for a abnormally large amount of time before the search box unfreeze and the cursor appeared, the right click never worked for me, not even a single time when I was using the 1909 build 18363.476… However, after uninstalling that update (if you can call it that) and start using again the 1903 build 18362.476 everything is fine again.

Also, with this new update the user needs to press enter or click in the arrow to start the search, this is a new futile and extra work for no reason, before this update the search was automatic, and started as soon as the user stopped writing.

I want to update windows to the latest version but foremost I need a working and functional Windows.

Yes with all these issues. I'll assume windows support people will not have any fixes and yes, go back to 1903 or fresh install of either 1903 or try 1909 again may be only fix. A work around for this file explorer problem may be not as important to me personally as it might of been a couple of years ago. But I'll try to minimize this and will not let this get to me as absolutely nothing created by humans is every perfect...sometimes just workable is the best you can hope for. Note: currently have 12 Window10 systems I care for and this type of stuff is still maddening.

I have no other fixes for this problem except to reinstall windows.

Same problem here...
