It has been some time now that in Windows 11, I experience this weird issue:
Now and then, I see a window (something bigger than a command prompt) opening and closing immediately.
It has a blue color, and I am unable to see if there is text inside. For sure if there is it is just a few characters.
It always opens at the same place; the center of the left monitor (I have 2 monitors).
I have tried to:
- disable all the Microsoft Office tasks
- not open Opera (as I thought it could have been related...)
- check all the registries and startup options (I don't find anything strange)
But it is still here.
As for the frequency, sometimes 2 or 3 times a day, sometimes not even once... I don't have an exact timing for it.
I am thinking to reinstall the OS as I don't know what this thing is doing.
Do you have any suggestions?
