Windows 10: "Search my stuff" unclickable, search window becomes blank white box

Hi,

I am a former Windows 7 Ultimate user who upgraded to Windows 10 Pro. I am having some major problems with the Search feature which renders Windows mostly unusable.

The problem consists of the following, in order:

1. Windows Search rebuilds the index with "We're getting search ready...", with only indexed start menu and desktop items in the list.
2. The "Search my stuff" feature is inaccessible. Pressing Enter or clicking it does absolutely nothing.
3. After a while, the popup portion is replaced by a blank white box of the same size with a vertical scrollbar. In this phase, even typing a file/folder name by path and pressing Enter does not work.
4. I have to restart my machine and the process starts over. (Sometimes killing "SearchUI.exe" from Sysinternals Process Explorer, which automatically restarts "SearchUI.exe", does the job instead)

Anyone know what's going on, and how to fix it?

Thank you!

:)

 

How to access or enable Search box in Windows 10 computer?

Cortana exists as an icon. Whether it's an icon or a search box (and I've set it both ways just to honor your question), the "My Stuff" and "Web" buttons no longer appear when I type a file name in the search box.

 

Windows Search Bar becomes unclickable, cannot change default applications

Main specs: surface laptop 64 bit windows 10 pro

After KB4090913 patch (part of the windows 10 1709), 1. my windows search bar becomes not clickable, the color turned grey, and clicking on it does not respond in any way. 2. I cannot change my default programs setting, clicking on anything does not change
anything, also, a “reset default app” notification pops up at every boot-up.

Also I cannot revert the update, tried it once and the act of uninstalling the update itself failed.
