There's one bug I've encountered in W11 that I find quite annoying.
Whenever I'm pressing the Windows button and start searching for an app (e.g. "Word", "File explorer"...), the first letters I type comes up in the search bar before it suddenly empties itself. Then I've to start over, decreasing effiency, especially if I press enter and accidentally open something else.
Say I press the Win-btn and start typing "word", the first letters "wo" would appear in the search bar before it gets erased and I might finish the last two chars, "rd", and press enter.
