Actually at the page [https://support.microsoft.com/en-us/help/4532695/windows-10-update-kb4532695] they say this:
- Updates an issue that causes a grey box to appear when you search within Control Panel and File Explorer.
- Updates an issue that prevents File Explorer's Search Bar from pasting clipboard content using the right mouse button (right-click).
- Updates an issue that prevents File Explorer's Search Bar from receiving user input.
So, search issues are expected to be cured with this one.
But first one needs to successfully install the KB without getting bluescreen though =)
