When filling the progress bar, the “pressing” of the keys is transmitted

Question

Windows

Some kind of poltergeist.
Given: an old laptop asus m9v, Windows XP home.
When installing any programs / updates, copying files, unzipping archives, in general, in any programs where hidden / visible progress is observed, the bar system "sees" the keystroke.
Such text is typed, opened the notepad and put the cursor ... (or in the English layout)
