  1. Rectangular box quickly flashes on bootup


    Has any noticed upon a reboot, when one comes to the Windows screen, a rectangular box quickly flashes and disappears? It's like it's there for a nanosecond and it's gone as quick as it comes.

    I thought it to be related to this one computer but then noticed the same thing on another computer. Am using Windows 10 with the latest updates and no malware / viruses on the System.

    It's as though something is attempting to load and then doesn't make it. No errors showing up whatsoever and all works well. Again, just wondering if this was something that came with an earlier update and wasn't fixed in the last one or is this a prelude to something more disasterous.

    :)

    Rectangular Box in Upper Left Corner

    I believe I accidentally generated this rectangular (not square) box while I was learning about the Magnifier. This rectangular (7.5 cm X 4.3 cm) box causes whatever is located underneath it to be slightly whiter than it normally would be. Everything functions properly while 'inside' this box. I have tried to 'ungenerate' this box by manipulating Magnifier but to no avail. I have investigated several forums/BBs/KBs but found no solution to my problem. What investigative step do I take next to solve this problem?
    Thank you.

  3. Flashing box or window

    I just installed a Windows 10 update & some kind of box flashes on & off every 30 seconds or so, on my screen in the upper left area. It flashes too quickly to tell if there is any text. Any suggestions about how to stop this?

    Rectangular box quickly flashes on bootup

    Item select rectangular box in list view since Creator's Update

    Since the release of Windows 10 Creator's Update, Microsoft introduced a subtle but (at least for me) very annoying feature when you're using List View in any of your folders:

    Now the blue item select rectangular box It occupies the entire size of the column in which the file is, when before the release of Creator's Update it only occupied the size of the file name. This is very annoying to me because I continually do "missclicks" and inadvertently clicking on a file. Is there any way to change this by modifying the registry or some other way?

    Thanks very much for your attention.
