Recently, an entry keeps appearing on my taskbar. It appears for less than a second before disappearing again. I once managed to click it, but no window popped up. The icon is a blank rectangular box and there is no description. It’s driving me nuts trying to work out what it is! How can I identify this process?
Programs do seem to come and go at times. When you’re diagnosing performance or security issues, understanding what’s coming and going can be important. Sometimes, it can just explain a flashing item in the task bar.
Fortunately, there is a fairly simple way to trace what’s happening.
