There is a small window that opened up on my desktop. It opened along with Windows when booting up.
Task manager does not show it as an open window:
Alt + Tab can switch focus to the window, but it does not have a title bar.
Windows + Tab does not see the window at all.
Visual Studio's Spy++ gives this information on it:
And finally, Process Explorer cannot find that handle given by Spy++.
How can I find out what process this window belongs to so that I can further investigate what it is?

I might be naive here but... where's the window? Is it the white rectangle over the malwarebytes and EPUB? – Doktoro Reichard – 2013-09-15T17:06:25.697
At any rate, if you can get focus, can you press Alt + F4, while analyzing the Processes tab? Maybe that will tell you what process it is. – Doktoro Reichard – 2013-09-15T17:08:48.783
Yes, it is the white rectangle in that picture. I agree with your idea of using Alt+F4 to close it while analyzing process explorer. Although I would like to explore further ideas before closing it just to make sure. – Ash – 2013-09-15T18:05:48.793
are you worried it's some kind of virus or malware? I'd just close and not obsess over it too much, unless it happens every time. – Sickest – 2013-09-15T18:09:55.343
How about going through your startup list and disabling startup items you suspect? Or just try the 'Diagnostic startup' in
msconfigto rule out the possibility that it's something wrong internally in Windows. – ADTC – 2013-09-15T19:06:38.363
