I can't say I've come across a white square bouncing on the systray before.
Are you certain it is a square. I know you can see a white circle with a hole in it, pop up briefly from time to time.
That is the System letting you know an app has located your location.
If that is what it is, you can manage what apps have access to your Location by going to
Start | Settings | Privacy then on the
left pane select
Location. Here you can turn it off altogether, or scroll down and toggle off individual apps that currently have permission to access your location.
Another possibility, is that you have a current update that has downloaded via Windows Update Service silently, and now its attempting to advice you that it needs attention. That usually displays like a white Microsoft flag, with a yellow circle in it, just to the right of the chevron (
^) n the systray.
Another possibility is something is temporarily alerting you, then hiding again in Hidden icons section, that you access by left-clicking that
^ symbol on your systray.
Other than that, the only other thing that might alleviate it would be to run a system file check:
- Tap/Press the Windows key once to give focus to the Cortana search box
- Type cmd then press Ctrl +Shift + Enter keys together simultaneously
- When the User Account Control prompts you, click yes
- At the command prompt type or copy & paste the following command:
Press enter key to execute the command
- When it's done, type exit and press enter key to close the Administrator: Command Prompt console
Note: If it reports it found an issue and repaired it, or failed to repair it, then re-run the previous command: SFC /SCANNOW
Sometimes, you need to run this command 3 or more times to fix any issues that may be found.
